[RESOLVED] DatagridView TextBoxColumn Autosuggest

[danasegarane]

Hi all,
I am using this method to set the AutoSuggest for the TextBox Column in Gridview. But it is not showing the list during typing ?

 private void GridView_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {
           string  Role =e.Control.AccessibilityObject.Role.ToString();
           switch (Role)
            {
                case  "ComboBox":
                    ComboBox cbo = e.Control as ComboBox;
                    
                    break;

                case "Text":

                    if (_CurrentCellColumnIndex == 0)
                    {
                        TextBox txt = e.Control as TextBox;
                        if (txt != null)
                        {
                            //txt.AutoCompleteMode = AutoCompleteMode.Suggest;
                         // private string[] _ModuleAutoCompleteSuggestion; //Declared in FormLevel
                            Array.Sort(_ModuleAutoCompleteSuggestion);
                            txt.AutoCompleteCustomSource.Clear();
                            txt.AutoCompleteCustomSource.AddRange(_ModuleAutoCompleteSuggestion);
                        }
                    }
                    break;

            }
