Question

In my winforms application, I have a DataGridView where one row uses the DataGridViewComboBoxColumn control so that it contains comboboxes for this column.

Is it possible to programatically replace some of the comboboxes in that column with something else? (for example a label saying “n/a”). I only want a combobox in certain rows.

You should use DataGridViewComboBoxCell property instead of DataGridViewComboBoxColumn property. Something like below:

for(int intCount=0;intCount<dgv.Rows.Count;intCount++)
{
   if(intCount % 2 == 0)  //Your own condition here
   {
      DataGridViewComboBoxCell cmb = new DataGridViewComboBoxCell();
      //cmb.Value   // assign values in the combobox
      dgv[0,intCount] = cmb;
   }
   else
   {
      DataGridViewTextBoxCell txt = new DataGridViewTextBoxCell();
      txt.Value = "n/a";
      dgv[0,intCount] = txt;
   }
}

In the above example, I am assigning the Individual cell properties in the first column.
