Hi guys,

I have a radgrid containing a nestedview. This view is filled with data by e.g.:

<asp:Label ID="LblDeliveryType" runat="server"><%# Eval("DeliveryTypeId")%></asp:Label> 

Above is an ID for a deliverytype, but I want to exchange this ID with some describing text. I have tried to do this in eventhandlers as OnItemDataBound and OnItemCommand at the RadGrid, OnPageViewCreated in my RadMultiPage, and some other places, but in these eventhandlers the data isn't filled out yet, and therefore I can't update the fields.

Any ideas what to do?

Hi Ahrensberg,

aspx:
<telerik:RadGrid ID="RadGrid1" DataSourceID="SqlDataSource1" AutoGenerateColumns="false" runat="server" OnItemDataBound="RadGrid1_ItemDataBound" >             
     <MasterTableView DataSourceID="SqlDataSource1" >                   
               <NestedViewTemplate>   
                        <asp:Label ID="LblDeliveryType" runat="server"><%# Eval("DeliveryTypeId")%></asp:Label> 
                   .... 




c#:
protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e) 
    { 
        if (e.Item is GridNestedViewItem) 
        { 
            GridNestedViewItem nestedItem = (GridNestedViewItem)e.Item; 
            Label lbl = (Label)nestedItem.FindControl("LblDeliveryType"); 
            lbl.Text = "My Custom Text";             
        } 
    } 

Thanks
Princy.

Hi Princy,

First of all, thanks for the quick reply!

I have tried something similar, but the problem is that the label is empty at this point. What I want is something like this:

if (e.Item is GridNestedViewItem) 
    GridNestedViewItem nestedItem = (GridNestedViewItem)e.Item; 
    Label lbl = (Label)nestedItem.FindControl("LblDeliveryType"); 
 
    string content = ""
    if (!lbl.Text.Equals("")) 
    { 
        switch ((DeliveryTypes) Convert.ToInt32(lbl.Text)) 
        { 
            case DeliveryTypes.DayToDay: 
                content = "Day-to-day"
                break; 
 
            case DeliveryTypes.Weekday: 
                content = "Weekday"
                break; 
        } 
    } 
 
    lbl.Text = content

But the lbl.Text is always empty, and therefore the "if (!lbl.Text.Equals(""))" is never entered. :-(

Best regards,
Kenneth
