Event Data

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

Property	Description
Allow	Gets or sets a value that indicates whether to show the edit form.
RowHandle	Gets the handle of the row that raised the event.

Remarks

In v21.2+ , handle the RowEditStarting, RowEditStarted, and RowEditFinished events to process how a user interacts with the Edit Form. You can also create commands in a View Model and bind them to the RowEditStartingCommand, RowEditStartedCommand, and RowEditFinishedCommand properties.

The EditFormShowing event allows you to cancel the operation (suppress the Edit Form). The following example disables the Edit Form for odd rows:

csharp

private void TableView_EditFormShowing(object sender, DevExpress.Xpf.Grid.EditFormShowingEventArgs e) {
    if(e.RowHandle % 2 != 0) {
        e.Allow = false;
    }
}
