Is there a way to limit client-side row selection to one row per grouping in a radgrid without causing a postback every time?

I used an old example (see below), but each click of a checkbox causes a postback which is disruptive to the process. I wasn't sure if there was some built in functionality or an easy way to check at the end if too many were selected.

Thank you..

I have a databound grid and am needing to add an additional column that will show a link to a google map for the location designated for the record in each row.

firstly im not sure i am doing this in the correct place, second issue im having (using hard coded parameters) is that the URL is not including these parameter values, the URL just shows the querystring names but none of these has the additional values.

as far as i can see the url format string seems correct and the urlparameters variable is getting the string values set ok, but for some reason they are not replacing the palceholder values in the url.

finally how would i get at the actual datatable values i need once i have this hard coded version working correctly?

heres my code:

Private Sub FillGrid()
        Try

            Dim gc As GridBoundColumn
            Dim glc As GridHyperLinkColumn           

            glc = New GridHyperLinkColumn
            Me.uxGrid.Columns.Add(glc)
            glc.HeaderText = "Map"
            Dim urlparameters As String()           
            urlparameters = New String() {"b12jp", "1234", "32.54545", "-2.2342342"}
            glc.DataNavigateUrlFields = urlparameters
            glc.DataTextFormatString = "{2:D}"
            glc.DataTextFormatString = "{3:D}"
            glc.DataNavigateUrlFormatString = "GoogleMaps.htm?postcode={0}&id={1}&lat={2}&lng={3}"
            glc.UniqueName = ""
            glc.ItemStyle.HorizontalAlign = HorizontalAlign.Center
            glc.Text = "Map"
            glc.HeaderStyle.Width = Unit.Pixel(40)
            glc.HeaderStyle.HorizontalAlign = HorizontalAlign.Center

            For Each col As DataColumn In _myData.Columns

                gc = New GridBoundColumn
                Me.uxGrid.Columns.Add(gc)
                gc.HeaderText = GetCaption(col.ColumnName)
                gc.UniqueName = col.ColumnName
                gc.DataField = col.ColumnName
                gc.Display = True
                gc.HeaderStyle.Width = Unit.Pixel(170)
                gc.ItemStyle.Wrap = True
            Next
           
        Catch ex As Exception
           
        End Try
    End Sub

Hi,

I'm trying to figure out how I can access the controls on a footer row outside the ItemDataBound event.

Objective:
I have a drop down list that has a OnSelected event. When the selection changes it needs to enable/disable controls that are in the footer row.

How can I accomplish this?
