HierarchyLoadMode "ServerOnDemand" not working with NestedViewTemplate

I'm trying to exploit the Telerik example here:
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx
The goal is to add editing capabilities to this demo, so in the NestedViewTemplate inside the page views of RadMultiPage I have FormView to present the data.
I'm facing several little problems even if overall it seems to work well.... I will try to ask help for one issue at a time.
The first issue I'm facing is that all the details inside the NestedViewTemplate are loaded on page load even if HierarchyLoadMode is set to "Conditional" or "ServerOnDemand".
I would like, for obvious reasons, to fire the FormView bindings inside the NestedViewTemplate only when the parent row is expanded.

Any hint? (structure follows)

<NestedViewTemplate>

<asp:Panel runat="server" ID="RadGrid1DetailContainer" CssClass="RadGridDetailContainer" Visible="false">

<telerik:RadTabStrip runat="server" ID="RadGrid1DetailTabStrip" MultiPageID="RadGrid1DetailMultipage1" SelectedIndex="0" CssClass="RadGridTabStrip">

<Tabs>

<telerik:RadTab runat="server" Text="Dati utente" PageViewID="RadGrid1DetailRadPageView1">

</telerik:RadTab>

<telerik:RadTab runat="server" Text="Anagrafica" PageViewID="RadGrid1DetailRadPageView2">

</telerik:RadTab>

<telerik:RadTab runat="server" Text="Altri dati" PageViewID="RadGrid1DetailRadPageView3">

</telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage runat="server" ID="RadGrid1DetailMultipage1" SelectedIndex="0" RenderSelectedPageOnly="false">

<telerik:RadPageView runat="server" ID="RadGrid1DetailRadPageView1" CssClass="RadGridPageView">

<asp:Label ID="Label1" Font-Bold="true" Font-Italic="true" Text='<%#: Item.UserId%>' runat="server" Visible="false"></asp:Label>

<asp:FormView id="RadGrid1DetailForm1" CssClass="RadGridDetailForm" DataSourceID="UserDetailsObjectDataSource" runat="server" ItemType="Eva.Entities.EvaUser">

<ItemTemplate>

<div class="form-horizontal form-stripe" style="padding: 12px;">

<eva:FormUserDetail ID="FormUserDetail1" Item="<%# Item %>" View="Detail2" runat="server" />

<div class="form-actions">

<button class="btn btn-primary">

<i class="icon icon-pencil"></i> Modifica

</button>

</div>

</ItemTemplate>

</asp:FormView>

<asp:ObjectDataSource ID="UserDetailsObjectDataSource" runat="server" TypeName="Eva.Bll.Core.EvaUsersManager" DataObjectTypeName="Eva.Entities.EvaUser" SelectMethod="GetById">

<SelectParameters>

<asp:ControlParameter ControlID="Label1" PropertyName="Text" Type="Int32" Name="UserId"></asp:ControlParameter>

</SelectParameters>

</asp:ObjectDataSource>

</telerik:RadPageView>

<telerik:RadPageView runat="server" ID="RadGrid1DetailRadPageView2">

</telerik:RadPageView>

<telerik:RadPageView runat="server" ID="RadGrid1DetailRadPageView3">

</telerik:RadPageView>

</telerik:RadMultiPage>

</asp:Panel

</NestedViewTemplate>

Inside RadGrid ItemCommand event I check the ExpandCollapse command to set the panel visibility accordingly

' Loads inner forms details when row is expanded

If e.CommandName = RadGrid.ExpandCollapseCommandName AndAlso TypeOf e.Item Is GridDataItem Then

DirectCast(e.Item, GridDataItem).ChildItem.FindControl("RadGrid1DetailContainer").Visible = Not e.Item.Expanded

End If

To trigger editing (expand the row and set the FormView in edit mode, always inside RadGrid ItemCommand, I linked a button to this and it works as expected

e.Item.Expanded = True

DirectCast(e.Item, GridDataItem).ChildItem.FindControl("RadGrid1DetailContainer").Visible = True

Dim gridFormView As FormView = DirectCast(e.Item, GridDataItem).ChildItem.FindControl("RadGrid1DetailContainer").FindControl("RadGrid1DetailMultipage1").FindControl("RadGrid1DetailRadPageView1").FindControl("RadGrid1DetailForm1")

gridFormView.ChangeMode(FormViewMode.Edit)

It seems that setting the panel RadGrid1DetailContainer to Visible="false" didn't help to delay the binding

Change the background color of the "Check All Items" option on ComboBox

I think I posted this in the wrong area the first time. Here it is again...

I've seen some similar threads to this question, but nothing that specifically addresses it. I have a RadComboBox that I add various items, too. I needed the ability to select "ALL" items, so I put in the EnableCheckAllItemsCheckBox property. Now, all of the items that I add have a white background, bu tthe all items checked button has a dark gray background that the UI people don't like. I've figured out some other issues with this, but the one thing remaining is...

How do I change the background color of the All items checked option? I've tried style sheets and some other things, but nothing works so far. This is what I use, along with some javacript to click it on default

<telerik:RadComboBox runat="server" ID="cboInvoiceStatus" CheckBoxes="True" AutoPostBack="true" HighlightTemplatedItems="true" IncludeSelectOption="false" EnableCheckAllItemsCheckBox="true" AllowCustomText="true" Localization-CheckAllString="Select All" >
</telerik:RadComboBox >

Any help is appreciated. Thanks,

Last Columns getting invisible while frozen the first column in grid

Hi,
I have one rad grid with 20 more columns, While i frozen the first column, the last three columns will be in out of the grid..
and i used to show full columns in grid with "UseStaticHeaders=True",
Bcoz am getting different count of columns from DB when i show a grid.

This is my grid:

------------------

<telerik:RadGrid ID="RadGrid2" runat="server" Skin="Vista" AutoGenerateColumns="false"

OnItemDataBound="RadGrid2_ItemDataBound" OnNeedDataSource="RadGrid2_NeedDataSource"

OnPreRender="RadGrid2_PreRender" Height="400px" Width="970px">

<MasterTableView HeaderStyle-CssClass="disable-highlight" Width="98%" HeaderStyle-HorizontalAlign="Center"

HeaderStyle-Wrap="true" HeaderStyle-Height="52px">

<Columns>

</Columns>

</MasterTableView>

<ClientSettings Scrolling-AllowScroll="true" Resizing-AllowColumnResize="true" Scrolling-SaveScrollPosition="true"

Scrolling-FrozenColumnsCount="2" Scrolling-UseStaticHeaders="true">

<Selecting AllowRowSelect="true" />

<ClientEvents OnColumnDblClick="myDblClickEvent" OnRowDblClick="RowSelectCheck" />

<Scrolling AllowScroll="true" UseStaticHeaders="true" />

</ClientSettings>

</telerik:RadGrid>

In Code Behind:

------------------

I have added the dynamic columns from DB like following.

GridBoundColumn objBound = new GridBoundColumn();

RadGrid2.MasterTableView.Columns.Add(objBound);

objBound.HeaderText = dtnewd.Columns[1].ToString().ToString();

objBound.UniqueName = dtnewd.Columns[1].ToString().ToString();

objBound.DataType = typeof(string);

objBound.DataField = dtnewd.Columns[1].ToString();

objBound.HeaderStyle.Width = 100;

objBound.HeaderStyle.Wrap = true;

objBound.ItemStyle.Width = 100;

objBound.ItemStyle.Wrap = true;

Can you anyone help me..?

Thanks

Can't get RadGrid ClientID from grid opened in RadWindowManager

I have an asp.net page with a RadGrid that displays insurance agents. The page opens a web user control for editing the insurance agent. That control also has a button that uses the RadWindowManager to show another page as a dialog that contains a RadGrid that displays insurance companies. When the insurance companies window is closed I need to add the selected insurance companies to the insurance agent being edited. The RadWindowManager seems to do something to interfere with the insurance company RadGrid's ClientID because the script returns just the ID entered at design time. I have also tried using the Page_PreRender event to add the script, but the ClientID is still wrong. I am willing to change how I am doing this if there is a better way.

The .aspx page RadWindowManager code:

<telerik:RadWindowManager ID="RadWindowManager1" runat="server">

<Windows>

<telerik:RadWindow ID="RadWindow1" runat="server"

OnClientClose="onInsuranceCompanyListClose"

ShowContentDuringLoad="false"

Modal="true"

Width="800px"

Height="600px"

Title="Add Insurance Companies"

VisibleStatusbar="false"

Behaviors="Move, Close">

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

... other page code

<button type="button" class="btn" onclick="addInsuranceCompany()">Add</button>

... still more code

<script type="text/javascript">

function addInsuranceCompany() {

radopen("InsuranceCustomerSelection.aspx", "RadWindow1");

}

function onInsuranceCompanyListClose(oWnd, args) {

alert(args.length + ' args');

}

</script>
