use the CellPainting event

C#

private void Grid_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
    if (e.RowIndex >= 0 && e.ColumnIndex >= 0)
    {
        if (Grid.Columns[e.ColumnIndex].Name == "CheckBoxColumn" && Grid.Rows[e.RowIndex].Cells["ColumnToCheck"].Value == <TrueHideValue>)
        {
            e.PaintBackground(e.ClipBounds, true);
            e.Handled = true;
        }
    }
}

Hi,
You can do that in ItemDataBound event of Datagrid.
Search the column you want with help of FindColumnByUniqueName and you can hide that column. Give a try...

Thank you,

You can handle this during ItemDataBound event of the datagrid:

In this event, while the data is binded row by row - add something like:

C#

protected void DataGrid1_ItemDataBound(object sender, DataGridItemEventArgs e)
{
// 
//
   //This textbox has the value of the cell based on which you need to hide checkbox
   Textbox txtCheckValue =   (Textbox)e.Row.FindControl("Textbox1"); 
   //Check the value condition as per your wish
   if(txtCheckValue_SatisfyCertainCondition())
   {
     Checkbox chkCurrRow =   (Checkbox)e.Row.FindControl("Checkbox1"); 

     // set visibility of your control
     chkCurrRow.Visible = false;
    }
//
//
}
