Event Data

The ResizeStarted event's data class is PopupResizeStartedEventArgs. The following properties provide information specific to this event:

Property	Description
CancellationToken	Specifies an object that propagates a cancellation notification.
Size	Returns the Popup’s size before the resize operation.

Remarks

When the AllowResize property is set to true, users can resize the Popup. Handle the ResizeStarted event to be notified when a user starts to resize the Popup. The event argument’s Size parameter returns the initial Popup size.

The example below obtains the component’s initial size:

<div @onclick="@(() => PopupVisible = true)">
    <p>CLICK TO SHOW A POP-UP WINDOW</p>
</div>

<DxPopup @bind-Visible="@PopupVisible"
         HeaderText="Header"
         BodyText="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris sit amet metus vel
                   nisi blandit tincidunt vel efficitur purus. Nunc nec turpis tempus, accumsan orci auctor,
                   imperdiet mauris. Fusce id purus magna."
         AllowResize="true"
         ResizeStarted="ResizeStarted"
         Width="@Width"
         Height="@Height">
</DxPopup>

@code {
    bool PopupVisible { get; set; } = false;
    string? Width = "200px", Height = "100px";
    void ResizeStarted(PopupResizeStartedEventArgs args) {
        (Width, Height) = ($"{args.Size.Width}px", $"{args.Size.Height}px");
    }
}

Handle the ResizeCompleted event to be notified when a user finishes to resize the component.
