Listbox not show data

[Naunton]

Hi all,

I have bind listbox as the following at RadAjaxManager1_AjaxRequest event.

ListBox1.DataTextField = "Desc"
ListBox1.DataValueField = "ID"
ListBox1.DataSource = dt
ListBox1.DataBind()

Data didn't show out in ListBox1.

But when I look at Watch window like this   ListBox1.Items.count it shows me 5 , when I look detail  ListBox1.Items(0).text it shows "AAA".
So this mean data are already in Listbox, but just not show.

Please advise how I can show these data?
Here is my Listbox sourcecode

<telerik:RadListBox ID="ListBox1" runat="server" CheckBoxes="True"
            Skin="Default" Height="300px" >
        </telerik:RadListBox>

Please Help...

Thanks and best regard.

Hello naunt,

You need to add the following setting to RadAjaxManager in order to make this work: "RadAjaxManager1 updates RadListBox1".

I hope this helps.
