I am trying to get jquery to handle the delivery of a message if the user tries to upload a file that is open. I am using the sample from here to work with. I know I must have missed something because the example from the link does what I want it to do but I am getting the script errors from below from my page.

Microsoft JScript runtime error: Exception thrown and not caught
Microsoft JScript runtime error: Unhandled Error in Silverlight Application [ScriptObject_InvokeFailed]

confusing because this is not a silverlight application but an ASP.NET

here is my client side code from the .ascx file.

<telerik:RadCodeBlock ID="RadFileUploadCodeBlock" runat="server">

<script type="text/javascript">

//<![CDATA[

function validationFailed(sender, eventArgs) {

$(".ErrorHolder").append("<p>Validation failed for '" + eventArgs.get_fileName() + "'.</p>").fadeIn("slow");

}

function closeDataContainer() {

$('div[id$=datacontainer]').hide('slow');

}

//]]>

</script>

</telerik:RadCodeBlock>

<div id="container">

<div id="content-container">

<div id="content">

<telerik:RadProgressManager runat="server" ID="RadProgressManager1" />

<telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1" MultipleFileSelection="Disabled"

OnClientValidationFailed="validationFailed" AllowedFileExtensions="xls, xlsx"

AutoAddFileInputs="True" Height="25px" Width="250px">

<FileFilters>

<telerik:FileFilter Description="*.xls; *. xlsx" Extensions="xls, xlsx"></telerik:FileFilter>

</FileFilters>

</telerik:RadAsyncUpload>

Select files to upload (xls, xlsx)

</div>

<div id="aside">

<asp:Button runat="server" ID="BtnSubmit" Text="Process File" OnClick="BtnSubmit_OnClick" />

</div>

<telerik:RadProgressArea runat="server" ID="RadProgressArea1" Width="582px">

</telerik:RadProgressArea>

<div id="Div1">

<asp:PlaceHolder ID="MessagePlaceHolder" Visible="false" runat="server"></asp:PlaceHolder>

</div>

<div class="ErrorHolder">

</div>

this.get_tree() is null

I have an existing site and Im starting to use telerik controls in the site but Im getting this javascript error.

this.get_tree() is null

Im using an existing ajaxControlToolkit.TabContainers.

On the first tab you click a button and it displays a third tab containing a RadFileExplorer
now you click on the first tab the 3rd tab goes away
then click on the second tab and the javascript error occurs.

This is some sample code to reproduce it (VB.net 4.0)

Protected Sub tabContainer1_ActiveTabChanged(sender As Object, e As System.EventArgs)

If (tabContainer1.ActiveTabIndex = 0 Or tabContainer1.ActiveTabIndex = 1) Then

With tabContainer1.Tabs(2)

.Enabled = False

.Visible = False

End With

End If

End Sub

Protected Sub Page_Load(sender As Object, e As System.EventArgs)

If Not IsPostBack Then

With tabContainer1.Tabs(2)

.Enabled = False

.Visible = False

End With

End If

End Sub

Protected Sub OpenNewTab_Click(sender As Object, e As System.EventArgs)

With tabContainer1.Tabs(2)

.Enabled = True

.Visible = True

End With

tabContainer1.ActiveTab = tabContainer1.Tabs(2)

End Sub

<form id="form1" runat="server">

[Solved] Find Nodes or Groups

Hello,

I'm building an OrgChart programatically and i want to get certain nodes. I don't find any way of doing this. The only method i found is 'GetNodeByHierarchicalIndex' but i can't get it to work. What is the int[] parameter that you need to pass.

Are there any other methods to get nodes etc...? For now i can manage to use GetAllGroupItems and looping the items and evaluating their level. It would be nice to get all elements for a specific level.

Regards,

Hans

Edit Issue

Hello Telerik,

Issue is user adds a new record to the RadGrid, uploads an image with the RadAsyncUpload and puts in some text. So they decide to go back in a and edit the record again. The RadAsyncUpload will not let them Update due to the image missing from the loaded files, they shouldn't have to find it and upload it again. I want the image in the RadBinaryImage field to populate the RadAsyncUpload on edit so they COULD remove it if they want to erase the image from the data record. Is this possible? If its not is there a workaround, otherwise the users are handicapped to find the image again, and they could never delete the image. Here is the ASPX code:

<telerik:GridTemplateColumn DataField="Image" HeaderText="Image" UniqueName="UploadImage" ItemStyle-HorizontalAlign="Center" ItemStyle-VerticalAlign="Middle" ItemStyle-Width="100px" ItemStyle-Height="100px">

<ItemTemplate>

<telerik:RadBinaryImage runat="server" ID="RadBinaryImage2"

DataValue='<%# Eval("Image") %>' AutoAdjustImageControlSize="false" Height="100px" Width="100px" ToolTip='<%#Eval("Name", "Product: {0}") %>' AlternateText='<%#Eval("Name", "{0}") %>' />

</ItemTemplate>

<EditItemTemplate>

<telerik:RadAsyncUpload runat="server" ID="AsyncUpload2" OnClientFileUploaded="OnClientFileUploadedStore" AllowedFileExtensions="jpg,jpeg,png,gif" MaxFileSize="1048576" OnValidatingFile="RadAsyncUpload1_ValidatingFile" />

<asp:Label runat="server" CssClass="lblWarning" Text="To make your image appear uniform, make the dimensions squared (ie: 100W x 100H) as PNG transparent."/>

</EditItemTemplate>

</telerik:GridTemplateColumn>

Thanks
SDI

[Solved] ajaxRequestWithTarget synchronously?

Hi, I'm using 'ajaxRequestWithTarget' method of RadAjaxPanel.
And it is asynchronously. Before the request is finished I would like to disable any action on client side.

It seems that update of RadAjaxPanel is performed asynchronously, is it possible to make it synchronous?
So for example I call 'ajaxRequestWithTarget' in the onclick event (client side event) of button. It looks like this event is finished before ajax request is done completely.

I know that there are events like:

ClientEvents-OnResponseEnd="OnResponseEnd"

ClientEvents-OnRequestStart="OnRequestStart"

So I could use them to disable this button after requestStart and before requestEnd, but this is additional work.
The simple question is: Can 'ajaxRequestWithTarget' be synchronous ?

Hope I described it good.
Regards.
Chris.

[Solved] RadWindow and validation

I am having a bit of an issue with rad window and calling it from a imagebutton.

My code looks like this:

function openRadWin() {

radopen("./cvv.jpg", "RadWindow1");

}

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true">

<Windows>

<telerik:RadWindow ID="RadWindow1" runat="server" ShowContentDuringLoad="false" Width="500px"

Height="260px" Title="CVV" Behaviors="Close" Modal="true" >

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

<asp:ImageButton ID="ImageButton1" runat="server"

OnClientClick="openRadWin();" ImageUrl="~/question.jpg" Height="20px" Width="20px" />

The issue i am having is that, when i click on the button, it causes validation. But if i add CauseValidation=False to my button, the window opens and closes immediately. It does not show the tool-bar at the top and does wait for end user action.
