Hello,

The code that you used is for setting the text of label which is placed in FooterTemplate of RadComboBox on changing the selection. I tried your code and it is working fine in my end (works only if you add FooterTemplate).

If you are trying to set the selected item text to label outside the RadCombobox, then you can try following code for that.

aspx:

<telerik:radcombobox id="RadComboBox1" runat="server" OnClientSelectedIndexChanged="calc">
<FooterTemplate>
<asp:Label ID="LabelFooter" Text="Text" runat="server"></asp:Label>
</FooterTemplate>
<Items>
<telerik:RadComboBoxItem runat="server" Text="Item1" Value="Item1"></telerik:RadComboBoxItem>
<telerik:RadComboBoxItem runat="server" Text="Item2" Value="Item2"></telerik:RadComboBoxItem>
<telerik:RadComboBoxItem runat="server" Text="Item3" Value="Item3"></telerik:RadComboBoxItem>
</Items>
</telerik:radcombobox>

<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

javascript:

<script type="text/javascript">
function calc(sender,args)
{
    var footer = sender._getFooterElement();  //Accessing the label in footer of RadComboBox
    footer.innerHTML = args.get_item().get_text(); //Setting the text of footer

    var label = document.getElementById("Label1"); // Access the label with id 'Label1'
    label.innerText  = args.get_item().get_text(); // Set the text of label
}
</script>
