How to apply conditional formatting in grid if no child records exist

[AkAlan]

I want to create a nested Grid and would like to be able to apply some formatting for rows in the master table if there are no child records yet created. I assume I need to put code in the ItemCreated event just not sure where to go from there. Any help would be appreciated.

Hello AkAlan,

I tried the following code in the PreRender event to achieve a scenario as yours. Probably it may help you:
c#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            if (item.ChildItem.NestedTableViews[0].Items.Count != 0)
            {
                item.BackColor = System.Drawing.Color.LightGreen;
            }
            else
            {
                item.BackColor = System.Drawing.Color.LightPink;

            }
        }
    }

Note: The HierarchyLoadMode property of the mastertableview should be either set to "ServerBind"/"Client" for the above code to work.

Hope this helps..
Princy.

Thanks Princy, That worked like a charm. I will repost the code in VB for others.

Imports Telerik.Web.UI

Partial Class MyRadGrid
    Inherits System.Web.UI.Page
    Protected Sub RadGrid1_PreRender(ByVal sender As Object, ByVal e As EventArgs) Handles RadGrid1.PreRender
        For Each item As GridDataItem In RadGrid1.MasterTableView.Items
            If item.ChildItem.NestedTableViews(0).Items.Count <> 0 Then
                item.BackColor = System.Drawing.Color.LightGreen
            Else
                item.BackColor = System.Drawing.Color.LightPink
            End If
        Next
    End Sub

End Class

Hi Princy, I just wanted to follow up on this post since I discovered something interesting. This solution won't work if your HierarchyLoadMode is set to ServerOnDemand. Thanks again for the help.
