Conditional Format with e.item.hasChildItems

[armando]

Hi, I need some of help

I have a grid master / detail, but I need to change the color of the row if I have information in the detail
Currently I have this in my code

Protected Sub RadGridPEDG_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGridPEDG.ItemCreated
        Dim tableName As String
        tableName = e.Item.OwnerTableView.Name
         
        If (e.Item.HasChildItems = true ) Then
             Dim dataBoundItem As GridDataItem = e.Item
             dataBoundItem.BackColor= Drawing.Color.Red
               
        End If
end  Sub

But not working

Thanks !!

Hello Armando,

Try the following code snippet in the prerender event.
C#:

Protected Sub RadGrid1_PreRender(sender As Object, e As EventArgs)
    For Each item As GridDataItem In RadGrid1.MasterTableView.Items
        If item.HasChildItems Then
            item.BackColor = System.Drawing.Color.Blue
        End If
    Next
End Sub

Thanks,
Shinu.

Hi Armando,

I would suggest you using another approach to hide the expand/collapse button if there is no information in the corresponding detail table. The same code successfully could be used to change the color of the item which has no additional information in them as well. You could review the following help topic, to see how this could be achieved:
http://www.telerik.com/help/aspnet-ajax/grid-hide-expand-collapse-images-when-no-records.html

Additionally, I am attaching a sample project to show a working example of the code.

Greetings,
