item bound error in hierarchy

[Webster Velasco]

hi im having a poblem when i try to expand my childtable on my data grid.. to be clear i have a prob on itemdatabound event         If TypeOf e.Item Is GridDataItem Then

Dim dataItem As GridDataItem = DirectCast(e.Item, GridDataItem)

Dim DateDiff As Int32 = Convert.ToInt32(dataItem("colDTDIFF").Text)

If DateDiff <= 30 Then

dataItem.BackColor = Drawing.Color.IndianRed

ElseIf DateDiff <= 60 Then

dataItem.BackColor = Drawing.Color.Yellow

ElseIf DateDiff <= 90 Then

dataItem.BackColor = Drawing.Color.SpringGreen

End If

End If

End Sub Dim DateDiff As Int32 = Convert.ToInt32(dataItem("colDTDIFF").Text) --> erro from this line

Hi,

You can set the Name property for your detailtable of your grid. Then in the ItemDataBound event of the grid, you can check for the Name of the ownertableview and access the item accordingly:

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" OnItemDataBound="RadGrid1_ItemDataBound">
       <MasterTableView Name="Master" DataSourceID="SqlDataSource1">
              <DetailTables>
                    <telerik:GridTableView DataSourceID="SqlDataSource2" Name="Detail" runat="server">

c#:

 protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        if (e.Item is GridDataItem && e.Item.OwnerTableView.Name == "Detail") // to check for the detail table
        {
            GridDataItem childItem = (GridDataItem)e.Item;




        }
    }

Hope this helps..
Princy.
