[Solved] ClientEvents Not firing

[Cal]

I have a case with following control structure (described below), even thought the Ajax is happening and the target drop down is being populated, the client events are not being fired.

UserControl
  --> RadCombo: Inside it I have an item template which has a RadTreeView, the structure like this

    

<telerik:RadComboBox ID="lstTransTypes" runat="server" MarkFirstMatch="true" Skin="Vista"
            EmptyMessage="Select tranaction Type" AllowCustomText="true" Width="100%" AutoPostBack="True"
            OnSelectedIndexChanged="lstTransTypes_SelectedIndexChanged">
            <ItemTemplate>
                <div id="div1">
                    <telerik:RadTreeView ID="tvwTransTypes" DataFieldID="id" DataFieldParentID="parentid"
                        Skin="Vista" CheckBoxes="true" CheckChildNodes="true" DataTextField="valuetext"
                        runat="server" Width="400px" Height="250px" OnNodeCheck="tvwTransTypes_NodeCheck">
                        <DataBindings>
                            <telerik:RadTreeNodeBinding Expanded="False" />
                        </DataBindings>
                    </telerik:RadTreeView>
                </div>
            </ItemTemplate>
            <Items>
                <telerik:RadComboBoxItem />
            </Items>
        </telerik:RadComboBox>

and the Ajax proxy is setup like this:

<telerik:RadAjaxManagerProxy ID="AjaxManagerProxy1" runat="server">

    <AjaxSettings>

        <telerik:AjaxSetting AjaxControlID="lstTransTypes">

            <UpdatedControls>

                <telerik:AjaxUpdatedControl ControlID="lstFilter" LoadingPanelID="RadAjaxLoadingPanel1" UpdatePanelHeight="" />

            </UpdatedControls>

        </telerik:AjaxSetting>

       


      


    </AjaxSettings>

             

</telerik:RadAjaxManagerProxy>

Hi Cal,

You should also ajaxify the RadComboBox control itself, this way it will trigger postbacks to the server and hit the OnSelectedIndexChanged event. Also use the RadAjaxManagerProxy only if you use master/content pages or WebUserControl, otherwise for standard purposes you can use the RadAjaxManager control.
 Here is a code illustrating this:

<telerik:RadAjaxManager ID="AjaxManagerProxy1" runat="server">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="lstTransTypes">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="lstFilter" LoadingPanelID="RadAjaxLoadingPanel1"
                            UpdatePanelHeight="" />
                            <telerik:AjaxUpdatedControl ControlID="lstTransTypes" LoadingPanelID="RadAjaxLoadingPanel1"/>
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>

If the problem persists we will appreciate further details of the code and what events exactly do not fire. More information on RadAjaxManager and RadAjaxManagerProxy can be found here:
