Hi,

I have a RadComboBox with a Header and Item Templates. I have set the EnableLoadOnDemand to true and using the OnItemsRequested event to populate the ComboBox. In the event am getting the values in a DataSet and using it as the datasource and binding it to the ComboBox using DataBind() method. But the data is not getting displayed and in the UI it is just showing the message as "Loading...". Am not even getting any exceptions and the datasource is being assigned properly. Am I missing something else?. Please help me in this regard. Thanks.

Below are the aspx and the script CS code i have written. Please find the attached screenshot as well.

<script type="text/C#" language="CS" runat="server">

protected void RadComboBox_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)

{

try

{

SomeClass sclass = new SomeClass()

DataSet ds = sclass.SomeMethod();

RadComboBox rcb = (RadComboBox)sender;

rcb.DataSource = ds;

rcb.DataTextField = "Column1";

rcb.DataValueField = "Column0";

rcb.DataBind();

}

catch (Exception ex)

{

throw ex;

}

</script>

<telerik:RadComboBox HighlightTemplatedItems="true" IsCaseSensitive="false" ID="ddlRadComboBox1" EnableLoadOnDemand="true" runat="server" TabIndex="9" OnItemsRequested="RadComboBox_ItemsRequested" style="width:30%;height:25px;" DropDownWidth="750">

<HeaderTemplate>

<table style="width: 750px; font-family:Verdana; font-size:11px;" cellspacing="0" cellpadding="0">

<tr>

<td style="width:35%;">Column 1</td>

<td style="width:65%;">Column 2</td>

</tr>

</table>

</HeaderTemplate>

<ItemTemplate>

<table style="width: 750px; font-family:Verdana; font-size:11px;" cellspacing="0" cellpadding="0">

<tr>

<td style="width:35%;"><%# DataBinder.Eval(Container.DataItem, "Column1")%></td>

<td style="width:65%;"><%# DataBinder.Eval(Container.DataItem, "Columns2")%></td>

</tr>

</table>

</ItemTemplate>

</telerik:RadComboBox>

Binding a Grid on ComboBox select using OData binding

Telerik Support Team,

We have an ADO.NET service which is hosted on a server. I would like to use a grid and bind it client-side using a data binding feature explained in one of the posts on the Telerik site. The grid should not be bind on load but should be bind when a user selects a value from a ComboBox. I know there is a support for filter options in a Data Service but don’t know how to get stated with it since there is no documentation found on your website.

Please advise how this can be achieved.

Thanks,

Ronak

Spanning Multiple Dates

I was wondering if it is possible to add appointments in the MonthView where the user has selected (highlighted) a few days. For example in the picture I have attached, I highlighted Jan 2 - Jan 5. Is there a property or event that is raised that lets me know if the user has selected several days?

[Solved] Highlight previously selected node after postback

Hi,

I wanted to 'highlight' previously selected node in my treeview after postback. I was using cookies to retain the treeview state after postback. Everything is working fine except after postback I am seeing parent node highlighted instead of child node.

Please take a look at the images I attached.

Childnode.jpg --> I selected node 'Baseball' and postback occurs
Parentnode.jpg --> I see the 'US Sports' highlighted instead of 'Baseball' node.

Any one?
