In My application I populate Nested Rad Grid with three nested tables:
<clients>
<matters>
<files>
</files>
</matters>
</clients

On each level there is a RadioButtonList with three buttons Approve, Assign, Forbid
There are two problems.
How do I populate the Radio Button lists on every level?
What event populates data in the nested views?
Seems easy on the main level, but I cannot make it work on the levels down:

 Protected Sub rgSessionClientsNested_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles rgSessionClientsNested.ItemDataBound
If e.Item.ItemType = GridItemType.AlternatingItem Or e.Item.ItemType = GridItemType.Item Then
Dim dataItem As GridDataItem = e.Item
Dim radCell As Telerik.Web.UI.GridTableCell = dataItem("authorize")
Dim forbidCell As GridTableCell = dataItem("forbidCnt")
Dim state As String = forbidCell.Text
Dim rdList As System.Web.UI.WebControls.RadioButtonList = radCell.FindControl("RadioButtonListClient1")
If state = "A" Then
rdList.Items(0).Selected = True
ElseIf state = "F" Then
rdList.Items(1).Selected = True
ElseIf state = "N" Then
rdList.Items(2).Selected = True
End If

Second question is related to the first one.
When the user clicks a button on any level I need to trigger a database update.
How can I do it?

Thanks in advance!
Here is my nested grid:

Hello,

 One way to populate the RaddioButtonList is programmatically in the ItemDataBound event of the related grid. There you can access the RadioButtonList by first accessing the cell and then using the FindControl method. There you also have access to the data coming from the datasource (through e.Item.DataItem property) which you can use to bind the correct selected value of the RadioButtonList.
As for the populating of the NestedViews when there is a more complex control in it (such as RadGrid) you need another approach different than the ParentTableRelations in the NestedViewSettings. In order to filter correctly the datasource of the inner grid - you have to add a control parameter to its where clause - (for example from a hidden label) as shown in this demo with the EmployeeID parameter of the inner grid.
