    Hello,    

    RadGridView manages user mouse and keyboard input over its rows by GridRowBehavior. Depending on the row type, RadGridView introduces different behaviors. Additional information about the row behavior and how to plug into it is available in the following help article: https://docs.telerik.com/devtools/winforms/controls/gridview/rows/row-behaviors

    However, if you need to detect keyboard events while the editor in RadGridView is activated, please refer to the following article: https://docs.telerik.com/devtools/winforms/controls/gridview/editors/handling-editors'-events

    I hope this information helps.

    Thank you for your response,

     

    But My Actual requirement is , When i press Esc Key  in an editable RadGridview Cell , i need to show some message, but the problem is when i press Esc Key CellEditorInitialized event is not triggering and the Whole data in the Cell gets cleared and Cell goes to editmode false.

    Is there any other way to detect the Esc key press.

     

    Thanks in advance

    Hello, Kishor,  

    Pressing the Escape key will abort the edit operation and the changes will be rejected. It is desired behavior. You can plug into this behavior by creating a custom GridDataRowBehavior and overriding its ProcessEscapeKey method. You can find below a sample code snippet demonstrating how to show a message box after the default logic for processing the Escape key has already been executed. It is up to you whether the default logic will be performed and what exactly to performed according to the requirements that you have: 

    public RadForm1()
    {
        InitializeComponent();
         
        //register the custom row  behavior
        BaseGridBehavior gridBehavior = radGridView1.GridBehavior as BaseGridBehavior;
        gridBehavior.UnregisterBehavior(typeof(GridViewDataRowInfo));
        gridBehavior.RegisterBehavior(typeof(GridViewDataRowInfo), new CustomGridDataRowBehavior());
    }
     
    public class CustomGridDataRowBehavior : GridDataRowBehavior
    {
        protected override bool ProcessEscapeKey(KeyEventArgs keys)
        {
            //execute the basic logic
            bool result = base.ProcessEscapeKey(keys);
     
            RadMessageBox.Show("Escape key is pressed");
             
            return result;
        }
    }

    I hope this information helps.
