Hi Ray,
Please try the following sample code snippet which works fine at my end. Let me know if you have any concern.
ASPX:
<telerik:RadComboBox ID="RadComboBox1" runat="server" DataSourceID="SqlDataSource1"
AllowCustomText="true" Filter="StartsWith" DataTextField="text" DataValueField="id">
</telerik:RadComboBox>
<telerik:RadButton ID="RadButton1" runat="server" Text="Get Selected Value" AutoPostBack="false"
OnClientClicked="OnClientClicked">
</telerik:RadButton>
JavaScript:
<script type="text/javascript">
function OnClientClicked(sender, args) {
var combo = $find("<%=RadComboBox1.ClientID %>");
alert(combo.get_selectedItem().get_text());
alert(combo.get_selectedItem().get_value());
}
</script>
Thanks,
Shinu.
