DetailTable contents of RadGrid lost on postback

I have a RadGrid with a DetailTableView. I populate a detail table in the OnDetailTableDataBind handler when the node is expanded.
However, when I postback the page, the DetailTableViews data will be empty.
Is there a way to persist the data?
I have tried to set ViewStateMode="Enabled" on the GridTableView.
The attached screenshot1.png depicts the grid after I have populated the detail table:

When I have changed the starttime for the RadGrid table item, the detail table is now emptied.

The attached screenshot2.png shows what it will look like.

Here is the declaration of the RadGrid:

<telerik:RadGrid ID="grd" AutoGenerateColumns="False"

OnDetailTableDataBind="grdActivitiesToCopy_OnDetailTableDataBind"

AllowMultiRowSelection="True" runat="server" ViewStateMode="Enabled">

<MasterTableView>

<Columns>

<telerik:GridClientSelectColumn UniqueName="DetailCheckColumn" />

<telerik:GridBoundColumn HeaderText="Date" DataField="StartDay"/>

<telerik:GridBoundColumn HeaderText="Time" DataField="TimeInterval"/>

<telerik:GridBoundColumn DataField="EventName" HeaderText="Activity"/>

<telerik:GridTemplateColumn HeaderText="New starttime">

<ItemTemplate>

<telerik:RadDateTimePicker runat="server" SelectedDate='<%#Eval("DateStart") %>'

AutoPostBackControl="Both"

OnSelectedDateChanged="GrdActivities_OnStartDateChanged"/>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="New endtime">

<ItemTemplate>

<telerik:RadDateTimePicker ID="endDateTime" runat="server"

SelectedDate='<%#Eval("DateEnd") %>'/>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

<DetailTables>

<telerik:GridTableView ShowHeadersWhenNoRecords="True" Name="Child"/>

</DetailTables>

</MasterTableView>

<ClientSettings>

<Selecting AllowRowSelect="true"/>

</ClientSettings>

</telerik:RadGrid>

grdActivitiesToCopy_OnDetailTableDataBind is called when the item is expanded (every time). I would prefer to have the detail tables populated in the Page_Load event.
Is that possible?

[Solved] WAI-ARIA: Can I assign roles to the RadPanelBar

I may be configured something wrong, but after enabling ARIA support on the RadPanelBar all I can see is that the items are rendered with a role="tab".

Shouldn't the RadPanelBar itself be rendered with a role="tabstrip" attribute?

Actually, in the project I'm assigned to, the RadPanelBar is used as a means of navigation - it's bound to the SiteMapDataSource. So I'd like to change the RadPanelBar's role to "navigation". How can I do this?

Your answers are appreciated.

Radwindow - random styles?

See the two images? Two radwindows in the same application, opened the same way. Two different "styles"? What's the deal with this? What controls it? I think they both look ok, but it would be sort of awesome if I could pick just one!

ID undefined on Client side

HI

What would cause this line to return Undefined. This was working in the VB version, but I'm redoing it in C# binding to an oData webservice deserialised using NewtonSoft.json library.

function OnClientAppointmentClick(sender, eventArgs) {
var booking_id = eventArgs.get_appointment().get_attributes().getAttribute("Id");
alert(booking_id);

I have the id in the datasource and the following markin in the control.

DataKeyField="Id"

OnDemand Duplicates Items on virtual scrolling

I have a RadComboBox with multiple columns of text shown, I have not found a solution to the virtual scrolling duplicating all items in the combo.

Here is the code - aspx:

<telerik:RadComboBox ID="radcmbProduct" runat="server" Width="400px" Height="200px" AllowCustomText="false"

EmptyMessage="Select a Product" EnableLoadOnDemand="True" ShowMoreResultsBox="true" DropDownWidth="600px"

EnableVirtualScrolling="true" HighlightTemplatedItems="true" MarkFirstMatch="true" ItemsPerRequest="60"

NoWrap="true" OnItemsRequested="radcmbProduct_ItemsRequested" OnItemDataBound="radcmbProduct_ItemDataBound">

<HeaderTemplate>

<ul>

<li class="col1">Title</li>

<li class="col2">System</li>

<li class="col3">Price</li>

</ul>

</HeaderTemplate>

<ItemTemplate>

<ul>

<li class="col1">

<%# DataBinder.Eval(Container.DataItem, "Title") %></li>

<li class="col2">

<%# DataBinder.Eval(Container.DataItem, "GameSystemName")%></li>

<li class="col3">

<%# DataBinder.Eval(Container.DataItem, "DisplayPrice")%></li>

</ul>

</ItemTemplate>

</telerik:RadComboBox>

and here is the code behind:

private DataSet GetProductDataSet(string productText)

{

string errorMsg = string.Empty;

DataSet DS = new DataSet();

Product.GetByName(FacilityID, productText, ref DS, ref errorMsg);

return DS;

}

protected void radcmbProduct_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)

{

DataSet data = GetProductDataSet(e.Text);

radcmbProduct.DataSource = data;

radcmbProduct.DataBind();

}

protected void radcmbProduct_ItemDataBound(object sender, RadComboBoxItemEventArgs e)

{

e.Item.Text = ((DataRowView)e.Item.DataItem)["Title"].ToString() + " | " + ((DataRowView)e.Item.DataItem)["GameSystemName"].ToString() + " | " + ((DataRowView)e.Item.DataItem)["DisplayPrice"].ToString();

e.Item.Value = ((DataRowView)e.Item.DataItem)["ProductID"].ToString();

}

So I need to find a way to prevent the items duplicating on scrolling, while maintaining the multiple column text capability. I have tried adding radcmbProduct.Items.Clear() prior to the DataBind() in the Items Requested method, however, this had no effect.

I have tried using the attributes as suggested in a previous post however, there were issues with that where the multi-column would only populate the first column.

I have not found a working solution.

Telerik RadGrid AJAX UI Batch Edit Mode Template Column with Dropdo

I am using Telerik RadGrid for AJAX UI. The grid is being used in batch edit mode. Grid has a column which needs to display dropdown in edit mode. In telerik forums, the approach is used by using SQLDatasource. But I wish to populate the dropdown when the the cell is clicked. I guess the only way to achieve is to use the client side api. Can somebody guide me on how to achieve this.
