Hi,
Im trying to build a combo box that will allow multiple selections. My issue is that when i build the checkboxes i can't get to bind text against each checkbox. it comes up empty. is this the correct way to achieve what i want ?
Thanks

 <radc:RadComboBox runat="server" ID="RadComboBox1" HighlightTemplatedItems="true" >
                <Items>
                    <radc:RadComboBoxItem Text="One" Value="1"  />
                    <radc:RadComboBoxItem Text="Two" Value="2"/>
                    <radc:RadComboBoxItem Text="Three" Value="3"/>
                </Items>
                <ItemTemplate>
                    <asp:CheckBox runat="server" ID="CheckBox"  Text=""/>
                    <span><%# DataBinder.Eval(Container, "Text") %></span>
                </ItemTemplate>
  </radc:RadComboBox>

Hello nadeetha,

You need to call the DataBind() of the RadComboBox in your Page_Load event.

RadComboBox1.DataBind(); 

I hope this helps.

I was having the same problem with Databinding inside a Template. Calling the DataBind method on the RadComboBox instance in the OnLoad event of the page (or UserControl) works indeed. Is it also possible to use the new ASP.NET "Bind" syntax? I tried this:

<telerik:radcombobox id="myList" runat="server" skin="Telerik">
   <itemtemplate>
      <asp:label runat="server" id="itemText" text='<%#Bind("Text") %>'></asp:label>
   </itemtemplate>
   <items>
      <telerik:radcomboboxitem Text="Item 1" />
      <telerik:radcomboboxitem Text="Item 2" />
      <telerik:radcomboboxitem Text="Item 3" />
   </items>
</telerik:radcombobox>

But it's not working; all rendered <li> items are empty. Am I doing it wrong?

Hello Sipke,

For the Prometheus controls you need to use DataBinder.Eval method.

This is described here: Controls > RadComboBox > Templates > Data Binding in Templates

I hope this helps.

Hi, is there a way to do this same databinding for a control that is created at runtime?
