ColumnView.ShowingEditor Event

Occurs when a cell inplace editor is about to open, and allows you to cancel this action.

Namespace:DevExpress.XtraGrid.Views.Base
Assembly:DevExpress.XtraGrid.v19.1.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type System.ComponentModel.CancelEventArgs containing data related to this event.

The following CancelEventArgs properties provide information specific to this event.
Property Description
Cancel Gets or sets a value indicating whether the event should be canceled.

Expanded Remarks

To identify the cell whose editor is about to be invoked, use the FocusedRowHandle and FocusedColumn properties. You can then set the e.Cancel parameter to false to prevent the editor from being shown.

The code sample below illustrates how to suppress in-place editor activation for all even grid rows. You can test this sample in this live demo.

If you need to prevent users from editing any Grid cells (or any cells that belong to the individual column), do not cancel the ShowingEditor event. Instead, disable the ColumnViewOptionsBehavior.Editable or OptionsColumn.AllowEdit settings.

The ShowingEditor occurs before the editor opens. If you need to perform specific actions after the editor is shown, handle the ShownEditor event instead.

Note

The ShowingEditor event does not fire for Auto Filter Row cells.
