Angular LoadPanel Properties

Set this object to null or undefined to disable animations.

The function passed to this property enables you to specify a custom condition for UI component closing. For instance, you can prevent closing until a user clicks a certain element.

$(function () {
    $("#loadPanelContainer").dxLoadPanel({
        // ...
        closeOnOutsideClick: function(e) {
            return e.target === $("#someElement").get()[0];
        }
    });
});

import { DxLoadPanelModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
    closeOnOutsideClick(e) {
        return e.target === document.getElementById("someElement");
    }
}
@NgModule({
     imports: [
         // ...
         DxLoadPanelModule
     ],
     // ...
 })

<dx-load-panel ...
    [closeOnOutsideClick]="closeOnOutsideClick">
</dx-load-panel>

<template>
    <DxLoadPanel ....
        :close-on-outside-click="closeOnOutsideClick">
    </DxLoadPanel>
</template>

<script>
import 'devextreme/dist/css/dx.light.css';

import DxLoadPanel from 'devextreme-vue/load-panel';

export default {
    components: {
        DxLoadPanel
    },
    methods: {
        closeOnOutsideClick (e) {
            return e.target === document.getElementById("someElement");
        }
    }
}
</script>

import React from 'react';
import 'devextreme/dist/css/dx.light.css';

import LoadPanel from 'devextreme-react/load-panel';

const closeOnOutsideClick = (e) => {
    return e.target === document.getElementById("someElement");
};

export default function App() {
    return (
        <LoadPanel ...
            closeOnOutsideClick={closeOnOutsideClick}>
        </LoadPanel>
    );
}

The closeOnOutsideClick function is called when a user clicks the UI component or outside it.

              container={containerElement}
          >
          </LoadPanel>
      );
  }

The UI component defines the default container on its initialization. This default container can be one of the following (if the element is absent, the component selects the next one):

• color swatch container

• .dx-viewport

• body

If you set this property to a specific element, the shading applies to this element. The LoadPanel calculates its size relative to the element.

This property allows you to use CSS for wrapper element configuration. You can customize the shade, resize, and drag zones.

The following markup illustrates relations between wrapper and root elements when you set copyRootClassesToWrapper to true:

<body>

    <!-- The following element is the root element on which the component is initialized. -->
    <!-- Specify classes to be copied to the wrapper element here. -->
    <div id="loadPanel" class="custom-class" ... ></div>

    <!-- The following element is the wrapper element. -->
    <!-- Custom classes are automatically copied from the root element. -->
    <div class="dx-overlay-wrapper dx-loadpanel-wrapper custom-class" ... > 

        <!-- The following element contains component content. -->
        <div class="dx-overlay-content" ... >
            <!-- ... -->
        </div>
    </div>
</body>

This property accepts a value of one of the following types:

• Number
  The height in pixels.

• String
  A CSS-accepted measurement of height. For example, "55px", "20vh", "80%", "inherit".

• Function (deprecated since v21.2)
  Refer to the W0017 warning description for information on how you can migrate to viewport units.

The following example shows how to subscribe to component property changes:

$(function() {
    $("#loadPanelContainer").dxLoadPanel({
        // ...
        onOptionChanged: function(e) {
            if(e.name === "changedProperty") {
                // handle the property change here
            }
        }
    });
});

    // ...
    handlePropertyChange(e) {
        if(e.name === "changedProperty") { 
            // handle the property change here
        }
    }

    components: {

    }, 
    // ...
    methods: { 
        handlePropertyChange: function(e) {
            if(e.name === "changedProperty") {

        // handle the property change here
    }
}

export default function App() { 
    return ( 
        <LoadPanel ...
            onOptionChanged={handlePropertyChange}
        />        
    ); 
} 

If you do not specify the container property and set the position.of to a specific element, the shading applies to this element. The LoadPanel calculates its size relative to the element.

When this property is set to true, the UI component text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.

DevExpress.config({
    rtlEnabled: true
});

Shading applies to the first specified element in the following sequence: container => position.of => window

If this property is set to true, the LoadPanel is displayed in modal mode, and users cannot interact with other UI components.

This property supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors
• Paint server address

If this property is set to true, a message is displayed and a load indicator turns in a circle while the view's content is loaded. Set this property to false to display only the text message. This can help avoid problems with animation used for the load indicator when running on a slow device.

This property accepts a value of one of the following types:

• Number
  The width in pixels.

• String
  A CSS-accepted measurement of width. For example, "55px", "20vw", "80%", "auto", "inherit".

• Function (deprecated since v21.2)
  Refer to the W0017 warning description for information on how you can migrate to viewport units.

The LoadPanel calculates its width relative to one of the elements in the following priority: container => position.of => window.
