Hi Vishnu,

Please correct your code as below:

C#:
if (dataItem["IsLocked"] != null && Convert.ToBoolean(DataBinder.Eval(dataItem.DataItem, "IsBoolFlagTrue"), CultureInfo.InvariantCulture))
{
//Your code
}

Thanks,

Thanks Shinu for your reply... i sorted it out ... but i have another problem
public IList<string> SelectedItemList
{
get
{
IList<string> ItemList = new List<string>();

foreach (GridDataItem dataItem in RadGrid.MasterTableView.Items)
{
if (IsGridItemSelected(dataItem))
{
 SelectedList.Add(dataItem["SelctionID"].Text);
}
}

return SeclectedIDList;
}
}

My code was working fine till we upgraded the telerik libraries & now dataItem["SelctionID"].Text derrived from RadGrid.MasterTableView.Items always returns null...

Hi Vishnu,

Its hard to identify the issue without your full code. Can you please make sure you have not set the Visible property of column to false? In case you want to hide a column set its Display property to false, then it can be accessed in the server side.

ASPX:
<telerik:GridBoundColumn UniqueName="OrderID" DataField="OrderID" Display="false">
</telerik:GridBoundColumn>

Thanks,
Shinu
