Insede of ItemDataBound

Hello I have a datagrid with template items - it's fairely simple, one column of checkboxes, and three columns of the labels (one label in one column). It's implemented like that (that's for one column):

<asp:TemplateColumn HeaderText="Item Description">
            <asp:Label Runat="server" ID="Label16">Item Description</asp:Label>
            <asp:Label ID="lblDescription" Runat="server" Width="250">
                  <%# DataBinder.Eval( Container.DataItem, "description" ) %>

and everything works fine.

I need to do some changes depending on to what my labels are bound - enabling or disable checkboxes in the first column - and I'm trying to check it like that:

if( (( Label )e.Item.Cells[ 3 ].Controls[ 1 ]).Text != someTextContro.Text ) { ... }

inside ItemDataBound and it is always empty... I checked MSDN and it's said this event is called AFTER the item is bound, so presumable if the item IS bound, controls inside this item should be bound as well and should contain some data... Yet it's not working this way.

I can suggest that controls inside the item are bound later, but what do I do in this case?? What is the event I can use to enable/disable my controls depending on what my controls inside items were bound to.

u can simply do so

1. go to design view of your datagrid, in "Properties" ,click "Events" tab, double click "ItemDataBound"
2. this will bring you to code behind
3. then u do sth. like this-->

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    DataRowView dv = (DataRowView)e.Item.DataItem;
    Label lblDescription= (Label)e.Item.FindControl("lblDescription");
    lblDescription.Text = dv["description"];
    //then do your modification
    if (lblDescription.Text == "")

I have exception "specified cast is not valid" on this line:

DataRowView dv = ( DataRowView )e.Item.DataItem;

any ideas?

found how to do it:

System.Data.Common.DbDataRecord ddr = ( System.Data.Common.DbDataRecord )e.Item.DataItem;
string ecert = ddr[ "description" ].ToString();

All credit goes to you as you pointed to the right direction and I was completely stuck :)

Thank you
