E1042

Occurs in the DataGrid or TreeList UI component if the key field is not set.

If your data is a JavaScript array, use the UI component's keyExpr property to specify the key field. Otherwise, use the key property in the store.

E1043

Occurs when the key property of the Store has an incorrect value.

Make sure that the field specified in the key property exists in all data objects associated with the Store.

E1044

Occurs in the TreeList UI component when the key field specified in the keyExpr property differs from the one specified in the Store.

Check that the key and keyExpr properties have the same value.

E1045

Occurs in the TreeList UI component if editing takes place without the key property specified in the Store.

Specify key in the Store.

E1046

Occurs in the TreeList and DataGrid UI components if the key field is not found in at least one data object.

Check that all data objects have the field specified in the UI component's keyExpr property or the Store's key property.

E1047

Occurs in the FilterBuilder UI component if the filter expression contains a data field that is not defined in the fields array.

Check that the data field used in the filter expression exists in the fields array.

E1048

Occurs in the FilterBuilder UI component if a condition in the filter expression contains an operation unavailable for the used field.

Check that the field's filterOperations property includes the operation.

E1049

Occurs in the TreeList or DataGrid when filterSyncEnabled is true and the columns[].dataField or columns[].name property is not specified in at least one column that allows filtering.

Check that all columns that allow filtering have the dataField or name property specified.

E1050

Occurs in the DataGrid or TreeList when trying to check the validationRules of a column that has a third-party editor in its editCellTemplate.

This error is specific to the popup and form editing modes. To correct it, choose a different editing mode or validate the editor's value in the onRowValidating function instead of using the validation rules.

E1051

Occurs in the HtmlEditor when the valueType is "markdown" but the markdown converter is not imported.

Import the converter:

import "devextreme/ui/html_editor/converters/markdown";
// or
// require("ui/html_editor/converters/markdown");

E1052

Occurs if the dataSource property is not specified in the UI component.

E1053

Occurs in a text editor when its buttons[] property is set to an invalid value.

Set the buttons[] property to an array that contains objects or string values.

E1054

Occurs in a text editor when at least one of its buttons does not have a name.

Check that the name property is specified for all the buttons.

E1055

Occurs in a text editor when at least one of its buttons has an invalid or non-unique value assigned to the name property.

Check that the name property has a valid and unique value for all the buttons.

E1056

Occurs in a text editor when it does not support the button type that you included in the buttons[] array.

Follow to the UI component's buttons[] description and ensure that you use only the types specified in the accepted values.

E1058

Occurs in the Scheduler when the startDayHour is set to a time that is later than the endDayHour.

To remove this error, specify a startDayHour that is earlier than the endDayHour,

E1059

Occurs in a DataGrid or TreeList when at least one of its columns has a non-unique value assigned to the name property.

Check that the name property has a unique value for all the columns.

E1060

Occurs in a DataGrid or TreeList when at least one of its editable columns does not have a name.

Check that the name property is specified for all editable columns.

E2001

Occurs when data of an unsupported type was provided to a UI component.

A UI component accepts an array of objects as a data source. If you try to pass anything else, the E2001 error occurs. To see an example of how to provide data for a UI component, refer to the Specify a Data Source help topics.

E2002

Occurs when axis type and data type are incompatible.

By default, data type of arguments and values is determined automatically based on the type of values from the data source. In some cases, specifying the data type explicitly may be required. For this purpose, the argumentAxis.argumentType and valueAxis.valueType properties can be used.

Similarly, the types of argument and value axes are determined automatically based on the data type, or set explicitly using the type property of the argumentAxis or valueAxis object correspondingly.

If data of a specified data type cannot be represented on an axis of a specified axis type, the E2002 error occurs. For example, if you try to represent data of a string type on an axis of a logarithmic type, you will get this error.

E2003

Occurs when one of the data source fields has an unsupported type.

Data source fields must contain values of numeric, string or date-time types only. Otherwise, the E2003 error occurs.

E2004

Occurs when values in a data source field have different types that cannot be cast to one type.

For example, this error takes place when among date-time values of a data source field, a string value occurs, and it cannot be converted into date-time type.

E2005

Occurs in the Funnel UI component when the specified value field is absent in the data source or all its values are negative.

Check that you set the valueField property to a field in the data source containing at least one positive value.

E2006

Occurs in the Sankey UI component when data objects are looped.

Check that data objects are not looped.

E2007

Occurs in the Sankey UI component if any of the required fields are not found in at least one data object.

Check that each data item has the following structure:

{ source: String, target: String, weight: Number }

E2008

Occurs in the Sankey UI component if the source or target field has an incorrect data type in at least one data object.

Check that each data item has the following structure:

{ source: String, target: String, weight: Number }

E2009

Occurs in the Sankey UI component if the weight field has an incorrect data type or value in at least one data object.

Check that the weight field in each data object is an integer number greater than 0.

E2101

Occurs when series.type property of Chart or PieChart has an unknown value.

You can find lists of acceptable series types for the Chart here and the PieChart here.

E2102

Occurs in Chart when two or more value axes on a single pane have the same name.

When you visualize data using several value axes on a single pane, these axes must have different names. If they do not, the E2102 occurs.

E2103

Occurs if an incorrect value was assigned to a property that accepts callback functions only.

This error occurs when you try to assign anything other than a callback function to properties like customizeTooltip in Chart or onPointSelectionChanged in PieChart.

E2104

Occurs if the logarithmBase property of Chart or RangeSelector was set to an invalid value.

This error may occur if you have set the logarithmBase property of a logarithmic axis (for Chart) or a logarithmic scale (for RangeSelector) incorrectly. The value assigned to this property must be an integer number greater than 1.

E2105

Occurs if an invalid value was specified for a strip or constant line.

A strip for an axis is specified by the startValue and endValue properties of an object in the strips array. A constant line is specified by the value property of an object in the constantLines array. All these properties accept numeric values. If you try to assign a value of another type to one of these properties, the E2105 error occurs.

E2202

Occurs when the startValue or endValue property of the RangeSelector's scale is not valid.

The startValue and endValue properties accept a numeric or date-time value depending on the scale data type. If anything else is passed, the E2202 error occurs.

E2203

Occurs in the RangeSelector UI component when the selected range is invalid.

Commonly, this error appears when either the value property or the setValue(value) method were used incorrectly. To troubleshoot, check that the range you are trying to select falls between the scale start and end values and that the type of the range values is the same as the scale type.

W1001

Occurs in the Map UI component if the key property value is changed after the UI component is created.

Do not change the key after the UI component is created.

W1002

Occurs when you are trying to access an item that does not exist.

Check the validity of the specified item.

W1003

Occurs in the List UI component if you try to select an item relating to a group that does not exist.

Check the validity of the specified group.

W1004

Occurs in the List UI component if you try to select an item that does not exist within the specified group.

Check the validity of the specified item.

W1005

Occurs when data is loaded twice when applying initial filter settings.

When both a value for the Filter Row and text for the Search Panel are set for the grid, data loading will be performed twice. The first load will be performed to learn data types for grid columns, and the second one - to apply filters. To avoid double data loading, set data types for all grid columns.

W1006

An error occurred while communicating with the map service. See the map service documentation.

W1007

Occurs in the TreeView if a node refers to a parent node that does not exist.

Make sure that the parent node exists, and that the field that provides its ID is identical to the keyExpr.

W1008

Occurs in the Scheduler UI component if you try to scroll to a date outside the current view.

Check that the scrollToTime(hours, minutes, date) method is called with a date in the current view.

W1009

Occurs in the List UI component when you try to search through data specified using the items property.

Specify data in the dataSource property instead.

W1010

Occurs when trying to select all the items in a grouped List with the selectAllMode set to "allPages".

Set the selectAllMode to "page" or use a data source with a plain structure. If you need hierarchical data and the capability to select all items across all pages, transform plain data using the DataSource's group property.

W1011

Occurs in the DataGrid UI component if the keyExpr property is specified and the data is not a JavaScript array.

Check that the DataGrid is bound to a JavaScript array.

W1013

Occurs if you specify the deprecated message field in the object passed to the custom(options) method.

Use the messageHtml field instead. Messages that contain HTML tags should be encoded. See the link above for an example.

W1014

Occurs when a page contains more SpeedDialAction UI components than specified in the maxSpeedDialActionCount property.

Increase the maxSpeedDialActionCount:

DevExpress.config({
    floatingActionButtonConfig: {
        maxSpeedDialActionCount: 7
    }
});
// ===== or when using modules =====
import config from "devextreme/core/config";

config({
    floatingActionButtonConfig: {
        maxSpeedDialActionCount: 7
    }
})

... or remove unnecessary SpeedDialAction UI components.

W1015

Occurs in the Scheduler when the range from the startDayHour to the endDayHour cannot be divided into even intervals because of the specified cellDuration.

To resolve this warning, calculate the range duration in minutes and find a cellDuration that divides the range duration without remainder. For instance, the range from 8 to 24 hours has a duration of 16 hours or 960 minutes. To specify the cellDuration, use any value that divides 960 without remainder.

W2002

Appears when none of the data source objects contain a valid argument or value field.

When providing data for Chart or a chart within RangeSelector, you must specify argument and value fields for chart series. If the chart data source does not contain the specified fields, or none of their values are valid, the UI component places the W2002 warning into the browser console.

W2003

Appears when the specified tick intervals lead Chart or RangeSelector to generating an excessive number of ticks.

When dividing the Chart's axes or RangeSelector's scale, you can specify intervals for major and minor ticks. However, if these intervals appear too small, the UI components will ignore them and divide the axes or scale using default tick intervals. In addition, the W2003 warning will appear.

W2101

Appears if the pane specified by the defaultPane property does not exist.

When a multi-pane chart is used, you can specify the pane to be used by default using the defaultPane property. The name of the pane assigned to this property must be also declared within the panes array. Otherwise, the W2101 warning appears, and the last pane declared in this array is used.

W2102

Appears if a value axis specified for a series does not exist.

Using a multi-axis chart), you should specify a value axis for each series using the series.axis property. These value axes should be declared in the valueAxis array as well. If not, a value axis with the name specified for a series will be created automatically, and the UI component will place the W2102 warning into the browser console.

W2103

Appears when a chart hides its title due to the layout being adapted.

This warning may appear if your scenario allows for the change of the UI component container's size. If so, when the size is reduced down to a minimum, which is specified by the height and width properties of the adaptive layout object, accessory UI component elements will be hidden. The W2103 warning, particularly, appears when the chart hides its title.

W2104

Appears when a chart hides its legend due to the layout being adapted.

This warning may appear if your scenario allows for the change of the UI component container's size. If so, when the size is reduced down to a minimum, which is specified by the height and width properties of the adaptive layout object, accessory UI component elements will be hidden. The W2104 warning, particularly, appears when the chart hides its legend.

W2105

Appears when a chart hides one of its axis titles due to the layout being adapted.

This warning may appear if your scenario allows for the change of the UI component container's size. If so, when the size is reduced down to a minimum, which is specified by the height and width properties of the adaptive layout object, accessory UI component elements will be hidden. The W2105 warning, particularly, appears when the chart hides one of the axis titles.

W2106

Appears when a chart hides labels of one of the axes due to the layout being adapted.

This warning may appear if your scenario allows for the change of the UI component container's size. If so, when the size is reduced down to a minimum, which is specified by the height and width properties of the adaptive layout object, accessory UI component elements will be hidden. The W2106 warning, particularly, appears when the chart hides labels of one of the axes.

W2107

Appears if the export menu was hidden due to the container's size being too small.

Enlarge the container's size.

W2108

Occurs if the browser does not support exporting images to the specified format.

Choose another format.

W2301

Occurs if the distance between the start and end scale values in a gauge equals zero.

Specify the startValue less than the endValue.

JavaScript

$(function () {
    $("#gaugeContainer").dxLinearGauge({ // or dxCircularGauge
        // ...
        scale: {
            startValue: 0,
            endValue: 50
        }
    });
});

$(function () {
    $("#barGaugeContainer").dxBarGauge({
        // ...
        startValue: 0,
        endValue: 50
    });
});
