    Hi,

    I meet a question on BeginEdit() function. When I call "this.gridView.Rows[1].Cells[1].BeginEdit();" , the text in Rows[1].Cells[1] will be selected so user will overwrite the previous text with the new type. I notice  System.Windows.Forms has a function  "BeginEdit(bool)" in GridView so developer can call

    "BeginEdit(bool)" to not select any contents. Does Telerik has any similar functions to help me unselect text in a Cell? Or How can I unselect text in a Cell programmaticly if I call BeginEdit()?

     

    Thank you,

    Chen

    Hello Chen,

    Thank you for writing.  

    In order to clear the selection of RadTextBoxEditor, it is necessary to handle the RadGridView.CellEditorInitialized event and subscribe to the GotFocus event of the hosted text box in the editor. Then, clear the selection as it is demonstrated below:
    public RadForm1()
    {
        InitializeComponent();
        this.radGridView1.CellEditorInitialized += radGridView1_CellEditorInitialized;
    }
     
    private void radGridView1_CellEditorInitialized(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
    {
        RadTextBoxEditor tbEditor = e.ActiveEditor as RadTextBoxEditor;
        if (tbEditor != null)
        {
            RadTextBoxEditorElement el = tbEditor.EditorElement as RadTextBoxEditorElement;
            el.TextBoxItem.TextBoxControl.GotFocus -= TextBoxControl_GotFocus;
            el.TextBoxItem.TextBoxControl.GotFocus += TextBoxControl_GotFocus;
        }
    }
     
    private void TextBoxControl_GotFocus(object sender, EventArgs e)
    {
        TextBox tb = sender as TextBox;
        tb.SelectionLength = 0;
        tb.SelectionStart = tb.Text.Length;
    }

    I hope this information helps. Should you have further questions I would be glad to help.
