Hi Charith,


How about the following approach to enable/disable combo?

aspx:

    <telerik:GridTemplateColumn>
        <EditItemTemplate>
            <telerik:RadComboBox ID="RadComboBox1" runat="server" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged">
                <Items>
                    <telerik:RadComboBoxItem Text="Yes" />
                    <telerik:RadComboBoxItem Text="No" />
                </Items>
            </telerik:RadComboBox>
        </EditItemTemplate>
    </telerik:GridTemplateColumn>
    <telerik:GridTemplateColumn>
        <EditItemTemplate>
            <telerik:RadComboBox ID="RadComboBox2" runat="server" OnClientLoad="OnClientLoad">
                <Items>
                    <telerik:RadComboBoxItem Text="123" />
                    <telerik:RadComboBoxItem Text="456" />
                </Items>
            </telerik:RadComboBox>
        </EditItemTemplate>
    </telerik:GridTemplateColumn>
</Columns>

javascript:

<script type="text/javascript">
    var combo;
    function OnClientLoad(sender, args) {
        combo = sender;
    }
    function OnClientSelectedIndexChanged(sender, args) {
        if (args.get_item().get_text() == "Yes") {
            combo.enable();
        }
        else {
            combo.disable();
        }
    }
</script>
