Hello
I'm using ASP.NET AJAX Q1 2012 version. When I put two RadAsyncUpload on one page, and try to set enabled property on false, i receive some JavaScript error. It's working when there is only one RadAsyncUpload control.
<telerik:RadScriptManager ID="RadScriptManager1" runat="server"> </telerik:RadScriptManager> <telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server"> </telerik:RadAsyncUpload> <telerik:RadAsyncUpload ID="RadAsyncUpload2" runat="server"> </telerik:RadAsyncUpload>
namespace test1 { public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { RadAsyncUpload1.Enabled = false; RadAsyncUpload2.Enabled = false; } } }
<telerik:RadTreeView ID="radTreeView" runat="server" Width="100%" AutoGenerateColumns="true" OnNodeClick="radTreeView_OnNodeClick">
<WebServiceSettings Path="BuildTrgMP.aspx" Method="GetChildNodes" />
</telerik:RadTreeView>
I have coded the GetChildNodes webservice call on the server side and this all works fine: when the user clicks a + on the tree, the little whirly appears which the webservice is called to populate the tree, which it does so correctly.
What I want to do is the opposite situation: when the user clicks a - on the tree, I want it to invalidate everything under that node such that the next time the + is clicked, the webservice is again called so that the list is updated from the database.
At the moment clicking the + just reopens the list which has previously been cached in the browser and the webservice is not called to refill the list.
How do I use OnClientNodeCollapsing (or any other approach) to invalidate the list such that pressing + causes the webservice to be called again ?
Thanks
