Vue FilterBuilder - fields

Configures fields.

Selector: DxField
Type:

Array<FilterBuilder Field>

Default Value: []

This property accepts an array of objects, each configuring a filter condition's appearance. Each condition consists of a data field, operation and value. A logical operation can combine conditions on the same level in a group.

DevExtreme HTML5 JavaScript Filter Builder Fields

See the Field section for details on fields you can specify in each object.

calculateFilterExpression

Specifies the field's custom rules to filter data.

Selector: calculate-filter-expression
Type:

Function

Function parameters:
filterValue: any

A user input value.
Contains an array if the selectedFilterOperation is one of the following: "between", "anyof", "noneof".

selectedFilterOperation:

String

A selected filter operation.

Return Value:

Filter Expression

A filter expression.

NOTE
When you configure the filterBuilder integrated in the DataGrid or TreeList, specify the calculateFilterExpression in the column with the same dataField instead.

The calculateFilterExpression function should return a filter expression. A basic filter expression has the following format:

[selector, comparisonOperator, filterValue]

  • selector
    A dataField to filter.

  • comparisonOperator
    One of the following operators: "=", "<>", ">", ">=", "<", "<=", "startswith", "endswith", "contains", "notcontains".

  • filterValue
    A user input value. Values from the selector are compared to this value.

In the following code, the calculateFilterExpression function implements an exclusive "between" operation. The function overrides the default inclusive implementation. Note that for the "between" operation, the filter expression has a different format:

[ [selector, ">=", startValue], "and", [selector, "<=", endValue] ]

NOTE
The this keyword refers to the field's configuration.

caption

Specifies the data field's caption.

Type:

String

| undefined
Default Value: undefined

If you do not specify this property, the FilterBuilder generates the caption based on the dataField property. For example, if dataField is "fullName", the caption is "Full Name".

customizeText

Customizes the input value's display text.

Selector: customize-text
Type:

Function

Function parameters:
fieldInfo:

Object

The field's data.

Object structure:
Name Type Description
value

String

|

Number

|

Date

The unformatted value (as specified using the editor or in the lookup's data source).
valueText

String

The value with the format applied.
Return Value:

String

The input value's text.

NOTE
The this keyword refers to the field's configuration.

dataField

Specifies the name of a field to be filtered.

Selector: data-field
Type:

String

| undefined
Default Value: undefined

dataType

Casts field values to a specific data type.

Selector: data-type
Type:

DataType

Default Value: 'string'

editorOptions

Configures the UI component used to edit the field value.

Selector: editor-options
Type: any

Depending on the dataType, the FilterBuilder offers a user different UI components for editing: TextBox, DateBox, Lookup, etc. In the editorOptions object, you can specify properties for the UI component.

Angular

Because editorOptions depend on the dataType, they cannot be typed and are not implemented as nested configuration components. Specify editorOptions with an object.

app.component.html
app.module.ts
<dx-filter-builder ... >
    <dxi-field ...
        [editorOptions]="{ format: 'currency', showClearButton: true }">
    </dxi-field>
</dx-filter-builder>
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';

import { DxFilterBuilderModule } from 'devextreme-angular';

@NgModule({
    declarations: [
        AppComponent

    ],
    providers: [ ],
    bootstrap: [AppComponent]
})
export class AppModule { }
Vue

Because editorOptions depend on the dataType, they cannot be typed and are not implemented as nested configuration components. Specify editorOptions with an object. We recommend that you declare the object outside the configuration component to prevent possible issues caused by unnecessary re-rendering.

App.vue

    <DxFilterBuilder ... >
        <DxField ...
            :editor-options="fieldEditorOptions"

            fieldEditorOptions: { format: 'currency', showClearButton: true }
        }

}
</script>
React

Because editorOptions depend on the dataType, they cannot be typed and are not implemented as nested configuration components. Specify editorOptions with an object. We recommend that you declare the object outside the configuration component to prevent possible issues caused by unnecessary re-rendering.

App.js
import React from 'react';

import FilterBuilder, {
    Field
} from 'devextreme-react/filter-builder';

class App extends React.Component {

                />
            </FilterBuilder>
        );
    }
}
export default App;
NOTE

Do not specify the onValueChanged property in this object. If you need to add custom logic to the default value change handler, override the handler in the onEditorPreparing function as follows:

jQuery
JavaScript
$(function() {
    $("#filterBuilderContainer").dxFilterBuilder({
        // ...
        onEditorPreparing: function(e) {
            if (e.dataField == "requiredDataField") {
                const defaultValueChangeHandler = e.editorOptions.onValueChanged;
                e.editorOptions.onValueChanged = function(args) { // Override the default handler
                    // ...
                    // Custom commands go here
                    // ...
                    // If you want to modify the editor value, call the setValue function:
                    // e.setValue(newValue);
                    // Otherwise, call the default handler:
                    defaultValueChangeHandler(args);

See Also

falseText

Specifies the false value text. Applies only if dataType is "boolean".

Selector: false-text
Type:

String

Default Value: 'false'

filterOperations

Specifies a set of available filter operations.

Selector: DxFilterOperation
Type:

Array<FilterBuilderOperation | String>

Default Value: undefined

The following table lists available filter operations by data type. The FilterBuilder uses the first operation in each array as the default operation for the specified data type.

dataType filterOperations
"string" [ "contains", "notcontains", "startswith", "endswith", "=", "<>", "isblank", "isnotblank" ]
"numeric" [ "=", "<>", "<", ">", "<=", ">=", "between", "isblank", "isnotblank" ]
"date", "datetime" [ "=", "<>", "<", ">", "<=", ">=", "between", "isblank", "isnotblank" ]
"boolean" [ "=", "<>", "isblank", "isnotblank" ]
"object" [ "isblank", "isnotblank" ]

The "isblank" operation returns null values and empty strings; "isnotblank" returns other values.

NOTE
Lookup's default operations are [ "=", "<>", "isblank", "isnotblank" ] regardless of the data type.

format

Formats a value before it is displayed.

Selector: DxFormat
Type:

Format

Default Value: ''

See the format section for information on accepted values.

This property also controls the user input in cells that use the DateBox UI component for editing. For cells that use other UI components, you can specify the editorOptions.format property.
