Hi,

I've got the following code:

</asp:SqlDataSource>

</form>

</body>

</html>

There's nothing in the code-behind file defaualt.aspx.cs. Problem I'm getting is that when I click on the paging or filtering, the AJAX request is served (I can see the telerik:RadAjaxLoadingPanel running), but it runs indefinitely and the data doesn't change. The data source itself is an Access 2007 file (Northwind 2007.accdb) located in the App_Data folder of the application.

I'm using "RadControls_for_ASP.NET_AJAX_2009_3_1103" on VS.Net 2010. The project where this Default.aspx page is set up is a "Telerik RadControls CSharp Web Application".

Thanks in advance for any help.

Sanjay.

Hi Sanjay,

I tried to replicate the issue which you described, but to no avail. I take the provided code and put it in a simple test project attached to this message.

Please, take a look at it and let me know if there are any differences at your ends, which I may be leaving out.

Hi Pavlina,

I've got another question then! Am trying to use the RadFilter, but am getting a error message on compilation saying "Unknown server tag 'telerik:RadFilter'." Am I missing a reference? I have version 2009.3.1103.35 "Telerik.Web.UI.dll" referenced in the project. and my web.config file looks like this:

<?xml version="1.0"?>

<system.web>

<pages>

</controls>

</pages>

</httpHandlers>

</httpModules>

</system.web>

<system.webServer>

</modules>

</handlers>

</system.webServer>

</configuration>

Any suggestions???

HI,

I'm getting a javascript error when using the RadGrid:

Webpage error details

The code is as follows:

<telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>

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

<telerik:AjaxSetting AjaxControlID="RadGrid3">

<telerik:AjaxUpdatedControl ControlID="RadGrid3" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadGrid ID="RadGrid3" DataSourceID="ObjectDataSource1" AllowPaging="True"

PageSize="5" runat="server" GridLines="None" Width="100%">

</telerik:RadGrid>

<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetCurrentOrders"

TypeName="MicrosoftSqlExpress2005" />

If I have the pager to have a mode of "NextPrevAndNumeric" I get the error. If I choose one of the other modes I don't get the error. Any suggestions?

Thanks,

Sanjay.

Here is a link to the project in zipped format:

https://www.yousendit.com/download/ZGJjY05saTFVbSt4dnc9PQ

The link expires on 3rd Nov 2010.

When you download the project, if you look at the following files, i've detailed the problems:

(1) "0001 Basic Paging.aspx": RadGrid1 and RadGrid2 are fine, RadGrid3 doesn't work though because of a different pager mode.
(2) "0002 Basic Paging With Defined Columns.aspx": This works ok, but if you change the pager mode to "NextPrevAndNumeric" it won't work.
(3) "0001 Basic Filtering.aspx": This works ok, but again changing pager mode to "NextPrevAndNumeric" it won't work.
(4) "0002 Filtering Template Columns.aspx": Trying to filter on any column doesn't work. Same for sorting and paging. With paging we have a simple mode of "NumericPages" but it still doesn't work.

Any problems Pavlina, just contact me.

Thanks for your help,

Sanjay.

Hi Sanjay,

You can fix the problem by upgrading to the latest version of the RadControls for ASP.NET AJAX. I am attaching a modified demo for reference.

I hope this helps.
