I am using a column containing combo boxes to format the column data in databound grid.

Eg the datatable that is bound to the grid contains values such as X, A and I display Cancelled or Accepted etc.

This works well but I will never need the user to edit this column so don't need the down arrow icon you click on to activate the drop down. Is there a way to hide this icon ?

Cheers

Hi Geoff,

Thanks for your interest in Syncfusion products.

You can prevent the user from changing the combobox cells by making them 'read-only' instead of hiding the dropdown icon button. Please try the following code in PrepareViewStyleInfo event to achieve this feature.


private void gridDataBoundGrid1_PrepareViewStyleInfo(object sender,GridPrepareViewStyleInfoEventArgs e)
{
if(e.ColIndex == 3 && e.RowIndex != 0) //Check for combobox cell
{
e.Style.ReadOnly = true;
}
}


Please check out the sample here.
