Combobox default value

Question

Hello, I have implemented a combobox in a column and I need this combobox by default before the user selects the item, it shows the content of the observable list. It's not working for me because the combobox has no ID to link to the header row.

"By default, GridComboBoxColumn displays the value by using the MappingName property" ok, but the property has no binding to the row header.

Hi Sergio Ayala,We are little unclear with your
scenario. But to display the default text in GridComboBoxColumn,
please refer to the below code snippets and attached sample.

this.sfDataGrid.DrawCell += SfDataGrid_DrawCell; 
   
  private void SfDataGrid_DrawCell(object sender,
  Syncfusion.WinForms.DataGrid.Events.DrawCellEventArgs e) 
  { 
      if(e.Column.MappingName == "ShipCountry" && string.IsNullOrEmpty(e.DisplayText)) 
      { 
          e.Style.TextColor
  = Color.Gray; 
          e.DisplayText
  = "Select
  Item"; 
      } 
  }
