[Nurietin]

Hi Telerik
How can I change dynamically ItemStyle.Font.Bold of

GridBoundColumn

I am trying with this code but does not work ?

GridBoundColumn

gc = RadGridDocument.MasterTableView.Columns.FindByUniqueName("Index") as GridBoundColumn;

foreach (var item in Items)

{

 

if (item.ParentID > 0)

gc.ItemStyle.Font.Bold =

 

true;

 

else

gc.ItemStyle.Font.Bold =

 

false;

}

Hello,

foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            item["Index"].ForeColor = System.Drawing.Color.Red;
        }

Thanks,

Hello,

Try accessing the BoundColumn in ItemDataBound event as shown below.
C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
 if (e.Item is GridDataItem)
 {
  GridDataItem itm = (GridDataItem)e.Item;
  TableCell cell = (TableCell)itm["Index"];
  cell.Font.Bold = true;
 }
}

Thanks,
Shinu.

I solved the problem

foreach (GridDataItem item in RadGridDocument.MasterTableView.Items)
{
var currDocument = Session.GetDocument((int)item.GetDataKeyValue("ID"));

if (currDocument.ParentID > 0)
item["Index"].Font.Bold = true;
else
item["Index"].Font.Bold = false;
}
