How to load Grid in UserControl using Web Services

I can load a RadGrid in the main page using get_masterTableView(). However, If I have the grid in an ASCX page, what do I need to do to load that grid from the main ASPX page? I can get a reference to the grid:
var myGrid = document.getElementById('<%= ((RadGrid)myControl.FindControl("RadGrid1")).ClientID %>')
but get_masterTableView() is not valid for myGrid.

Binding dropdown template column to BindingList value

I'm binding a RadGrid to a BindingList, when I edit a Template column with a dropDown I'm trying it to keep the previously selected value

here is a sample of my code:

<telerik:GridTemplateColumn HeaderText="Contributor" UniqueName="Contributor" DataField="Contrib">

<EditItemTemplate>

<asp:DropDownList ID="ddContributor" runat="server" DataSourceID="ldsContibutors"

DataTextField="ContributorName" DataValueField="ContributorID" AppendDataBoundItems="True"

SelectedValue='<%# Eval("Contrib.ContributorID") %>'>

<asp:ListItem>Select a value</asp:ListItem>

</asp:DropDownList>

</EditItemTemplate>

<ItemTemplate>

<%# Eval("Contrib.ContributorName") %>

</ItemTemplate>

eval works fine but bind throws an exception: DataBinding: 'Telerik.Web.UI.GridInsertionObject' does not contain a property with the name 'Contrib'.

I also tried in cs but I cannot find the value in the item["Contributor"].Text
then I tried witha a label in the Item template, ((Label)item["Contributor"].findControl("labelID")).Text but it's always ""
any help will be apreciated thanks!

Pre Render Event looping through many items

I have this code in the Pre Render event in one of my RadGrids.............

For Each item As GridDataItem In Radgrid_AddRemoveProvider.MasterTableView.Items
            Dim lblPID As Label = DirectCast(item.FindControl("lblPID"), Label)

            Dim btnAddProvider As LinkButton = DirectCast(item.FindControl("btnAddProvider"), LinkButton)
            Dim btnRemoveProvider As LinkButton = DirectCast(item.FindControl("btnRemoveProvider"), LinkButton)
            Dim lblFullName As Label = DirectCast(item.FindControl("lblFullName"), Label)
            Dim btnFullName As LinkButton = DirectCast(item.FindControl("btnFullName"), LinkButton)
            ' Dim lblContactType As Label = DirectCast(item.FindControl("lblContactType"), Label)
            ' Dim ddPreferredContact As DropDownList = DirectCast(item.FindControl("ddPreferredContact"), DropDownList)

            If lblPID.Text = Nothing Then
                btnAddProvider.Visible = True
                'ddPreferredContact.Visible = True
                'lblContactType.Visible = False
                btnRemoveProvider.Visible = False
                lblFullName.Visible = True
                btnFullName.Visible = False
            ElseIf lblPID.Text <> Nothing Then
                btnAddProvider.Visible = False
                'ddPreferredContact.Visible = False
                'lblContactType.Visible = True
                btnRemoveProvider.Visible = True
                lblFullName.Visible = False
                btnFullName.Visible = True
            End If

Next

However it loops through this code 100 times looping through each item in my RadGrid. The problem is that it goes through this loop every time I perform any sort of event on the page. Is there anyway I can tell it to stop looping through this code when i am not working with this RadGrid on the page. I tried putting the code in the ItemCreated event, but it does the same thing. Overall I believe this is effecting the performance and speed of my page.
