AllowAutomaticInserts and invisible column

Hi,

I have grid that uses OpenAccessLinqDataSource with automatic insert, update and delete. I'm trying to implement insert but with following scenario.

Data table (as class) has 4 properties. ID, IdFirm, Number and Activity. I have set invisible property for ID and IdFirm colum. For ID is clear why I hide it. As for IdFirm I dont wont to display it because it must be connected to some othe class on page and user MUST NOT enter that information.

How to implement automatic insert and intersept that call to add IdFirm property to object and then save it database.

I use command item (AddNewRecordButton)

A minor cosmetic suggestion

Most end-users, if they recognise the word "Ajax" at all, prolly still think it is a product to clean the bathtub with.

Consider changing the default text for the Spell Check button from "AJAX Spellchecker to "Spellchecker"

showtext

Should showtext="false" work when I also have size="large"?

If "yes" then it's broken as I have...

<tools name="Proofing" tab="Home">

<tool name="AjaxSpellCheck" size="large" showtext="false"/>

</tools>

but see screenshot.

Upload Error in Load Balanced Server

Hello ,

We are facing a sporadic issue when using the RadUpload control in our website.

The application is hosted in a load balanced server and the session is stateless.

This is what is happening. If the user uploads 10 files (then it creates 10 temp files on the server in RadUploadTemp folder.)We have 2 app servers and when the user access the server, it might get connected to appserver1. But there is no guarentee that for all the 10times it tries to access the server, it will always go to appserver1 as they are loadbalanced. The moment it hits appserver2, we get file not found exception. If it always hits appserver1 then all the files will be uploaded successfully

We are get the error every now and then. Is there any configuration that can be set in the control that would make the control work without issues in case where the load balancing is set and the session is stateless?

Thank you
Regards
Pankaj

validationFailed handler not working

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"

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">

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
