Solution 1

Your best bet would be to have a separate collection which you can populate using LinQ, that stores all the positive columns of your datatable, and then bind the combo box column to this separate collection.

Hope this helps

You can do it in code behind by using OnItemDataBound Event of datagrid.

The data is bounded to the datagrid upon firing this event.So, get the column 2 value as

<pre lang="c#">
protected void OnItemDataBound(object sender,DataGridItemEventArgs e)
if(e.Item.Cells[1].Text==1)//column2 value is either 0 or 1 whether true or false
{
//Do Some Action To remove data from Column 1 such as 
   //e.Item.Cells[0].Text=String.Empty;
}
