WebExplorerBar Inside UpdatePanel
posted

Can someone kindly tell me why this will not postback? All I want to do is have an asp button click event fired on click of the nodes that do not have any children. This works if I take the explorer bar out of the update panel. It also works if I pre-expand the nodes then click on an end node first. For some reason, after I click on a parent node I'm no longer able to postback to the server.

One other odd behavior is when I click on a parent node first then navigate to an end node, I can get a postback to happen if I double-click the node.... this is not normal.

<script type="text/javascript">

function webReportMenu_ItemClick_Client(sender, eventArgs) {

   var item = eventArgs.getExplorerBarItem();

   if (item.get_childrenCount() == 0) {

      var btn = $get('<%= this.btnExplorerPost.ClientID %>');

      btn.click();

   }

}

</script>

 

<asp:UpdatePanel runat="server" UpdateMode="Always">

<ContentTemplate>

<asp:Button ID="btnExplorerPost" runat="server" OnClick="btnExplorerPost_Click" />

<ig:WebExplorerBar ID="webReportMenu" runat="server" DataSourceID="SampleDataSource" GroupExpandBehavior="SingleExpanded" >

<ClientEvents ItemClick="webReportMenu_ItemClick_Client" />

<DataBindings>

<ig:ExplorerBarItemBinding DataMember="ReportLevel" TextField="Name"/>

<ig:ExplorerBarItemBinding DataMember="ReportCategory" TextField="Name"/>

<ig:ExplorerBarItemBinding DataMember="ReportName" TextField="Name"/>

</DataBindings>

</ig:WebExplorerBar>

</ContentTemplate>

</asp:UpdatePanel>

 

<asp:XmlDataSource runat="server" DataFile="~/Sample.xml" ID="SampleDataSource" XPath="/Root/ReportLevel" />

    Hi there,

    I think you have to use the triggers functionality of update panel in order to do this:

    <Triggers>

     

     

     

     

     

     

    <asp:AsyncPostBackTrigger ControlID="btnExplorerPost" />

     

     

     

    </Triggers>

    Put the code above into the update panel.
