[Solved] Radcombobox itemtemplate and ajax

[Travis]

Hi I am trying to hook up an ajax event every time a checkbox is clicked inside of a dynamically populated radcombobox itemtemplate that contains a label and checkbox.  I get the ajax to work on the first checkbox that is clicked and it refreshes the grid using ajax but once you click a second item it causes a postback. What is the best way to accomplish this?

    Protected Sub chk1_CheckedChanged(ByVal sender As Object, ByVal e As EventArgs)
        rgReceived.Rebind()
    End Sub

    Protected Sub rcbBehavior_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadComboBoxItemEventArgs) Handles rcbBehavior.ItemDataBound
        Dim chkBox As CheckBox = e.Item.FindControl("chk1")
        RadAjaxManager1.AjaxSettings.AddAjaxSetting(chkBox, rgReceived, RadAjaxLoadingPanel1)
    End Sub

 

        <telerik:RadComboBox ID="rcbBehavior"
    runat="server" AllowCustomText="true" ZIndex="3"

    OnClientDropDownOpening="OnClientDropDownOpenedHandler" EmptyMessage="Select Behaviors..."
                                HighlightTemplatedItems="true" Width="240px">
            <ItemTemplate>
                <div>
                    <asp:CheckBox ID="chk1" runat="server" Checked="true" AutoPostBack="true" onclick="onCheckBoxClick(this);"
                                            OnCheckedChanged="chk1_CheckedChanged" />
                    <asp:Label ID="Label1" runat="server" AssociatedControlID="chk1">
                                <%#Eval("Title")%>
                                        </asp:Label>
                </div>
            </ItemTemplate>
        </telerik:RadComboBox>

Hi Travis,

I suggest you allow the whole combobox to update the grid, not every checkbox in its template.
