PopupClosingEventArgs Class
Contains data for the Closing event.
Namespace: DevExpress.Blazor
Assembly: DevExpress.Blazor.v24.2.dll
NuGet Package: DevExpress.Blazor
Declaration
public class PopupClosingEventArgs :
CancelEventArgs
Remarks
The Closing event is raised before the Popup is closed. Use the event argument’s CloseReason property to identify which action closes the Popup. You can set the Cancel
property to true
to cancel a close action.
Close Reason | Description |
---|---|
CloseButtonClick | A user clicks the Close button in the Popup header or clicks a custom button (if you call the predefined CloseCallback to create this button). |
EscapePress | A user presses Escape. |
OutsideClick | A user clicks outside the Popup’s boundaries. |
Programmatically | You set the Visible property to false or call the CloseAsync method. |
You can also handle the Closed event that fires after the Popup is closed.
In the following example, neither the Close button in the header nor the custom OK button closes the Popup until a user enables the checkbox in the footer.
<div @onclick="@(() => EulaVisible = true)">
<p>CLICK TO SHOW A POP-UP WINDOW</p>
</div>
<DxPopup @bind-Visible="@EulaVisible"
ShowFooter="true"
HeaderText="DevExpress EULA"
Closing="EulaPopupClosing"
Closed="EulaPopupClosed">
