Open and Close Popup

Open Popup

The ShowPopup() method invokes the editor popup. You can open a popup using the OpenPopupCommand.

The PopupOpening event occurs right before the popup is actually opened. After the dropdown has been shown, the editor fires the PopupOpened event.

Close Popup

The CancelPopup() method closes the editor’s popup window, discarding all the changes made.

To programmatically hide the editor’s popup window and save the changes, use the PopupBaseEdit.ClosePopup method. You can also close a popup using the ClosePopupCommand.

The PopupClosing event occurs right before the popup is actually closed. After the dropdown has been closed, the editor fires the PopupClosed event.

Useful API

The PopupContentTemplate property allows you to specify the drop-down window content.

Useful API

You can make an editor focus its popup on opening. To do this, set the FocusPopupOnOpen property to true.

The ShowSizeGrip property allows you to enable a size grip, so your end user can resize the popup window.
