Hi Truong, 

 

Thanks for the update. 

 

 

As per GridGroupingControl architecture, the controls present in the RichTextBox were added in a panel. These controls can be hidden by setting Controls.Visible property to False inside the TableControlCurrentCellShowingDropDown event. If the content of the cell are edited by using RichTextBox, to save the changes done, the text entered is set to the the current cell by using SetValue property. Please refer to the below code and sample, 

 

Code Example 

gridGroupingControl1.TableControlCurrentCellShowingDropDown += GridGroupingControl1_TableControlCurrentCellShowingDropDown; 

 

private void GridGroupingControl1_TableControlCurrentCellShowingDropDown(object sender, GridTableControlCurrentCellShowingDropDownEventArgs e) 

 { 

     var ren = e.TableControl.CurrentCell.Renderer as GridRichTextBoxCellRenderer; 

     var panel = ren.DropDownContainer.Controls[0] as GridRichTextEntryPanel; 

     for (int i = panel.Controls.Count-1; i >= 0; i--) 

     { 

         if (!(panel.Controls[i] is RichTextBox)) 

             panel.Controls.Remove(panel.Controls[i]); 

     } 

     //To remove the unwanted spaces 

     panel.Controls[0].Dock = DockStyle.Fill; 

 } 

 

private void GridGroupingControl1_TableControlCurrentCellCloseDropDown(object sender, GridTableControlPopupClosedEventArgs e) 

{ 

    var ren = e.TableControl.CurrentCell.Renderer as GridRichTextBoxCellRenderer; 

    var panel = ren.DropDownContainer.Controls[0] as GridRichTextEntryPanel; 

    var s = panel.Controls[0].Text;         

    int rowIndex = e.TableControl.CurrentCell.RowIndex; 

    int colIndex = e.TableControl.CurrentCell.ColIndex; 

    GridTableCellStyleInfo sty = e.TableControl.GetTableViewStyleInfo(rowIndex, colIndex); 

    Record rec = sty.TableCellIdentity.DisplayElement.GetRecord(); 

    if (rec != null) 

        rec.SetValue(sty.TableCellIdentity.Column.Name, s); 

}
