AsyncUpload can't access addtional field on server side, always return null value

I tried to put AsyncUpload into one of my usercontrols, but I always got null exception error when I tried to get addtional field at code behind. At first I thought that's user control's problem, but later on, even I put the exact the same code as demo into my test page, I got the same null exception error on this line :

<%#((Telerik.Web.UI.UploadedFile)Container.DataItem).GetFieldValue("TextBox").ToString()%>

Anyone else got same issue as I got? Pls take a look whenever you have time, really appreciate.

<telerik:RadScriptManager ID="ScriptManager1" runat="server" />

Maintaining linebreaks in multiline RadTextBox

Pretty simple question. I'm sure its quite easy but its causing me some trouble.

I've written these 2 lines, neither or which seem to pick up on the line breaks.

desc = Replace(Me.txt_description.Text, System.Environment.NewLine, "<br />")

desc = Replace(Me.txt_description.Text, vbCr, "<br />")

Problem when loading several radcharts on remote.

I got on a page 6 radcharts which are dynamically loaded when clicking on a button.

On my local server, I got no problem, the 6 radcharts are loading without any problem.
But on remote server, when I launch my ajax request, 2 to 4 of the charts load (not the same ones everytime), and for the remaining one, I get the following message :

"Error loading RadChart image.
You may also wish to check the ASP.NET Trace for further details.
Display stack trace?"

If I click OK, the website show me the chart that "couldn't be loaded".

I suppose the problem is that the answer to my ajax request come too soon and the website try to show an image that isn't finished to create, isn't it ?

If it's the case, is it a "delay" property or something to make the chart wait X seconds more before binding ?

Regards,
Nicolas

Telerik comboxbox, asp validators and IE9

I'm having an issue with using a few telerik comboxes. I have them setup like this:

<telerik:RadComboBox ID="ddlM" runat="server" Skin="Forest" Width="220px" ExpandDelay="10"

AllowCustomText="true" MarkFirstMatch="true" OnClientSelectedIndexChanged="lookupValue"

TabIndex="3" />

along with asp required field validators setup like this:

<asp:RequiredFieldValidator runat="server" ID="RequiredFieldValidator2" ControlToValidate="ddlM"

Display="Dynamic" InitialValue="" Type="String" ValidationGroup="g1" ErrorMessage="required."

Text=" X" />

<asp:RequiredFieldValidator runat="server" ID="CompareValidator2" ControlToValidate="ddlM"

Display="Dynamic" InitialValue="Select" Type="String" ValidationGroup="g1" ErrorMessage="required."

Text=" X" />

the problem i am having (and this problem is ONLY happening in IE9, not IE7 or IE8), is that when i enter custom values in the aforementioned combo box(s), the required field validators fire prompting me that input is required. If I choose something from the combox's list, its fine. I thought the validators validated the text property. It would appear that in IE9 this is not the case. Is there any guidance out there on this?

RadAjaxPanel inside RadWindow - how to close window on server side?

Hi

I am using Radwindow as a modal popup for inline form editing. I have created a wizard, using standard 'asp:panels', inside the ContentTemplate of the Radwindow to break up the form in to smaller chunks. In each asp:panel there is a 'next' and 'back' button which is used to navigate between them. These buttons control server side functions to show/hide the various panels during navigation, and perform some form validation etc. in the background. I need this server side functionality.

I posted a message before to prevent flickering between navigation steps and the solution provided was to use a RadAjaxpanel. This worked fine until I try to close the Radwindow using a button with server side code. The server side code is again necessary, as this button saves the content of the form in the Radwindow before closing the Radwindow.

The problem is that when the 'save' button is clicked the Radwindow does not disappear - it will only do this if the RadAjaxpanel is removed from the code - but I need the RadAjaxpanel to prevent the flickering! My sample code is below. Any ideas?

Thanks in advance.

Kevin

PS This code is in a dynamically loaded usercontrol in a page with a master page - a standard 'asp:ScriptManager' is in this master page.
