Hi there. I have an aspx page that initially shows a treeview. When a child node on the tree is pressed, i want a RadGrid on the page to be popualated. I set the datasource and do a databind() call but it doesn't seem to be working. I've also tried using needDataSource but it has the same problem. Here's my code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Data;

using Telerik.Web.UI;

using MCMwebapp.Utilities;

namespace MCMwebapp

{

public partial class frmLookupTables : System.Web.UI.Page

{

int CurrentDemog;

bool LookupDataLoaded;

bool isOPS = false;

string selectedNode;

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

}

protected void LookupsTree_NodeClick(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e)

{

RadTreeNode currNode = e.Node;

if (currNode.Nodes.Count == 0) {

if (currNode.ParentNode.Text != "Treatments" && !String.IsNullOrEmpty(currNode.Text))

{

selectedNode = currNode.Text;

Session["selectedNode"] = selectedNode;

loadLookupGrid();

}

protected void loadLookupGrid()

{

using (ServiceReference1.Service1SoapClient myService = new ServiceReference1.Service1SoapClient())

{

if (Session["selectedNode"] != null)

{

LookupGrid.DataSource = myService.getTable();

LookupGrid.Databind();

}

My aspx code:

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="frmLookupTables.aspx.cs" Inherits="MCMwebapp.frmLookupTables" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

<asp:Label ID="LookupLabel" runat="server"></asp:Label>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="LookupGrid">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="LookupGrid" LoadingPanelID="TablePanel"></telerik:AjaxUpdatedControl>

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxPanel ID="TreePanel" runat="server" HorizontalAlign="NotSet" style="background-color:#808080; float:left" Width="40%">

<telerik:RadTreeView ID="LookupsTree" runat="server" OnClientNodeClicked="ClientNodeClicked" OnNodeClick="LookupsTree_NodeClick">

</telerik:RadTreeView>

</telerik:RadAjaxPanel>

<telerik:RadAjaxLoadingPanel ID="TablePanel" runat="server" HorizontalAlign="Right"

style="background-color:#E92326; float:right" Width="40%" >

<telerik:RadGrid ID="LookupGrid" runat="server" BackColor="Gray"

BorderColor="#404040" BorderStyle="Solid" CellSpacing="0" GridLines="None"

Skin="MetroTouch">

<FilterMenu EnableImageSprites="False">

</FilterMenu>

</telerik:RadGrid>

</telerik:RadAjaxLoadingPanel>

<script type="text/javascript">

function ClientNodeClicked(sender, eventArgs) {

var node = eventArgs.get_node();

node.toggle();

}

</script>

</asp:Content>

Any ideas? thanks

OnNodeEdit not triggered correctly in public Demo

Hi!

I might have found a bug in your demo application and this bug is also haunting my application.
In the demo, found here: http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/contextmenu/defaultcs.aspx.,
you can right clikc on a node and create a new folder.

Now, if you change the default text, a postback will occure and the server side event "OnNodeEdit" will be triggered. But, if you dont change the text and just press enter, no server side event will occure and the node will not be saved.

How do I fix this?

Regards,
Per

[Solved] RadWindow "moveto" Throwing Invalid Argument In IE 8

Hey guys,

Not getting very helpful information from the debugger on this, but we have a situation where one RadWindow has a button that calls a function that opens another RadWindow and then position it using "moveTo". This works very well in Chrome but in IE 8 it throws the following exception:

Invalid argument. Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_radScriptManagerCommon_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-US%3acaf9918e-87b7-4f16-b8e8-f81c9ff8f4ab%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%3aen-US%3a8a277cf4-155d-4ba9-b3c0-d6f62646e5f2%3a16e4e7cd%3af7645509%3a22a6274a%3aed16cbdc%3a24ee1bba%3a19620875%3a874f8ea2%3af46195d3%3acda80b3%3a383e4ce8%3a92fe8ea0%3afa31b949%3a490a9d4e%3abd8f85e4%3ae330518b%3a2003d0b8%3a1e771326%3ac8618e41%3a8e6f0d33%3a7165f74%3aaa288e2d%3a58366029%3ae524c98b, line 6 character 63497

The debugger points to a highlighted piece of code that appears to be deep inside some Microsoft stuff:

a.top=d+"px"

I've done quite a bit of searching but haven't seen anyone with the same problem. I did find a post where someone had a similar error as the one above, but it was with opening a RadWindow. Most of the stuff I've seen have recommend to add a setTimeout, but that hasn't worked.

Any help would be greatly appreciated. Thanks.

Programmatically add words to dictionary

Is it possible to add words to the dictionary on the fly? It's infeasible to know the words beforehand. If not, how do I prevent the red squiggles from appearing?

Cascading Select in Javascrip and Telerik RadFormDecorator

I am trying very hard to make my cascading select decorate using telerik form decorator. Here is my js,


var attributes = s.attributes;
 for (var i = 0, iLen = attributes.length; i < iLen ; i++) {
     $elem.append('<option ' + (selectedValue === attributes[i].id ? 'selected ' : '') + 'value="' + attributes[i].id + '">' + attributes[i].name + '</option>');
 }

after this I am calling,


formDecorator.decorate($elem[0], false);

It only works first time when the parent select changed(in a cascading select). But after this nothing works. I have tried,


formDecorator.decorate();

and

formDecorator.updateSelect($elem[0]);

Is there is any way to make it work?

Cancel Image uploading is not actually cancel the AJAX request send to server, which cause apllication hanges

Hi,

I am using radasyncupload cutomhttphandler in my application, but it hangs the application some times while uploading (Even not hits on server side). To handle this scenario I have used a js timer to cancel the uploading after a specific time on clicking cancel button from js but Cancel Image uploading is not actually cancelling the AJAX request send to server, which cause application hangs. For terminating the request we also clicks on remove button it Aborts the request but Initiator is in pending state(please refer attached screen shot) and site still in hanged state. After 5-6 minute it automatically timeout and site is again responsive.

Is there any option set the timeout for this uploader control only? We cannot set AutoPostbackTimeOut of scripmanager and Httpruntime timeout in config.
Or any option to completely terminate the request sends to the server for uploading.

Please find attached screen shot for referring pending request after cancelling and removing the request.

Controls get "visibility: hidden !important" when using RadDecorator

Hey! I am using Telerik Ajax controls in some app, but i have this problem where i use a RadDecorator and all my input controls are getting
"visibility: hidden !important" and wont work properly obviously. I tried removing this RadDecorator and the "visibility: hidden !important" attribute disappear and all the controls work fine but the RadComboBox. I am also using the Metro Skin.

this is how i am using the RadDecorator:

<telerik:RadFormDecorator ID="FormDecorator1" runat="server" DecoratedControls="CheckBoxes, RadioButtons" />

one of the most important controls i am using is the RadComboBox, this is one of the controls that stop working, like if it was disabled, and it is written like this:

<telerik:RadComboBox ID="RadComboBoxBranchOffice" runat="server" DataSourceID="ObjectDataSourceBranchOffice"

DataTextField="BranchOfficeName" DataValueField="BranchOfficeId" AppendDataBoundItems="true" MaxHeight="350">

<Items>

<telerik:RadComboBoxItem Text="--Seleccionar--" Value="0" />

</Items>

</telerik:RadComboBox>

<asp:ObjectDataSource ID="ObjectDataSourceBranchOffice" runat="server" SelectMethod="GetAllByOfficeId"

TypeName="Location.BranchOfficeBll">

<SelectParameters>

<asp:ControlParameter ControlID="RadComboBoxOffice" Name="OfficeId" PropertyName="SelectedValue"

Type="Int32" />

</SelectParameters>
