Hi, how can I bind a RadGrid when I need to include details from more than one entity?

I have the following code that runs, definitely brings back data but does not show anything in my grid (with AutoGenerateColumns set to "true"):


I don't mind admitting my LINQ to Entities knowledge is "ongoing" but you can see what I am trying to do: for every ParentEntity, get me their properties and for every ChildEntity under that, get me their properties as well. I want the grid to display those.

Because the ChildEntity may not necessarilly immediately have a ParentEntity, I can't do a master / detail view with two grids.

but when i move from Page 1 to Page 2 And come back to page 1 with some query string when click on radio button list it does not post back

Plz See Code below

 <div id="divshippmethod" class="PageSection full ShippingInformation" runat="server">
        <h1>
            Shipping Method</h1>
        <div class="content">
            <asp:RadioButtonList CellSpacing="0" CellPadding="0" ID="rbtnShippingMethod" RepeatDirection="Horizontal"
                AutoPostBack="true" runat="server">
                <asp:ListItem Text="&nbsp;&nbsp;Shipping Information" Value="0" Selected="True"></asp:ListItem>
                <asp:ListItem Text="&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Mail List Upload"
                    Value="1"></asp:ListItem>
            </asp:RadioButtonList>
        </div>

Rajax setting are below
 <telerik:AjaxSetting AjaxControlID="rbtnShippingMethod">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="rbtnShippingMethod" LoadingPanelID="RadAjaxLoadingPanel" />
                        <telerik:AjaxUpdatedControl ControlID="pnlShipping" />
                        <telerik:AjaxUpdatedControl ControlID="pnlMailListUpload" />
                    </UpdatedControls>
                </telerik:AjaxSetting>

Protected Sub rbtnShippingMethod_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles rbtnShippingMethod.SelectedIndexChanged
        If rbtnShippingMethod.SelectedValue = 1 Then
            pnlShipping.Visible = False
            pnlMailListUpload.Visible = True
        Else
            pnlShipping.Visible = True
            pnlMailListUpload.Visible = False
        End If
    End Sub
first time when pnlMailListUpload. is true, it has a button which Response.Redirects to another page on which i do some activity and come back to this page again.

now if i select any item from the radiobuttonlist then rbtnShippingMethod_SelectedIndexChanged is not firing , on doing inspectElement from FF we found that the required postback JS (__dopostbakc) is not attached with the onclick event of the radio button.

plz help.

How to find the detail table in ItemCommand Event in radgrid?

Hi,
we are using RadControls for ASP.NET AJAX Q3 2010 in SharePoint 2010 custom user controls.
In general, if I have a scheduler in a user control and after adding the scripts programmatically as posted here (asp-updatepanel-and-radscheduler-issues) it works fine with update panel and the default ajax script manager of sharepoint.
The problem starts when using a RadTabStrip that loads to the RadMultiPage user controls programmatically. When the user selects the tab that loads a user control that contains a scheduler control then a javascript error occurs ('b.TouchScrollExtender' is null or not an object).
If I don't include the RadTabStrip into an update panel then I can select another tab and navigate away from the tab with the scheduler control, but if I use update panel or even RadAjaxManager and AddAjaxSetting programmataically then I cannot navigate away and do any other action.

Thank you in advance,
Ilias

I have a horizontal Gantt chart with a single series date data loaded for the two YAxis'. I'd like to be able to turn on the XAxis MajorGridLines so that a line appears from left side of the chart to right in order to make the XAxis item labels line up with the bars.

Is this possible?
