I have a sinking feeling that I'm going to feel stupid after one of you helps me with this one...

I'm positioning a RadWindow via OffsetElementID. That's working exactly as I want it to (opening the window right beside where the link in the Radgrid is), but whenever I click the Details link the page scrolls back to the top (it's not  a page refresh), which often hides the window if it was further down the list. Anyway ideas on how to stop this?

<telerik:RadWindowManager ID="RadWindowManager1" runat="server">
            <Windows>
                <telerik:RadWindow  
                    id="RadWindow1"
                    offsetelementid="detailsLink"

Here's my codebehind:
Private Sub RadGrid1_Init(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles RadGrid1.Init
    Dim menu As GridFilterMenu = RadGrid1.FilterMenu
    Dim i As Integer = 0
    While i < menu.Items.Count
        If menu.Items(i).Text = "NoFilter" Or _
           menu.Items(i).Text = "Contains" Or _
           menu.Items(i).Text = "DoesNotContain" Or _
           menu.Items(i).Text = "StartsWith" Or _
           menu.Items(i).Text = "EndsWith" Or _
           menu.Items(i).Text = "EqualTo" Or _
           menu.Items(i).Text = "NotEqualTo" Or _
           menu.Items(i).Text = "GreaterThan" Or _
           menu.Items(i).Text = "LessThan" Then
            i = i + 1
        Else
            menu.Items.RemoveAt(i)
        End If
    End While
End Sub 'RadGrid1_Init
    
Protected Sub clrFilters_Click(ByVal sender As Object, ByVal e As EventArgs)
    For Each column As GridColumn In RadGrid1.MasterTableView.Columns
        column.CurrentFilterFunction = GridKnownFunction.NoFilter
        column.CurrentFilterValue = String.Empty
    Next
    RadGrid1.MasterTableView.FilterExpression = String.Empty
    RadGrid1.MasterTableView.Rebind()
End Sub
  
Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs)
    If TypeOf e.Item Is GridDataItem Then
        Dim detailsLink As HyperLink = DirectCast(e.Item.FindControl("detailsLink"), HyperLink)
        detailsLink.Attributes("href") = "#"
        detailsLink.Attributes("onclick") = [String].Format("return openDetailsWin('{0}');", e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("pkRequestID"))
    End If
End Sub

Hi RW,

Try setting the detailsLink hyperlink like this:

Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs)
    If TypeOf e.Item Is GridDataItem Then
        Dim detailsLink As HyperLink = DirectCast(e.Item.FindControl("detailsLink"), HyperLink)
        'detailsLink.Attributes("href") = "#"
        'detailsLink.Attributes("onclick") = [String].Format("return openDetailsWin('{0}');", e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("pkRequestID"))
        detailsLink.Attributes("href") = "javascript:void(0);"
        detailsLink.Attributes("onclick") = [String].Format("openDetailsWin('{0}'); return false;", e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("pkRequestID"))
    End If
End Sub

When href is set to #, the browser treats the link as an anchor and usually will automatically scroll the page to top while trying to find that anchor in the content. To avoid that, I would suggest to use javascipt:void(0); instead.
