styling is not working correctly on newer version of RadMenu

Hi,

Earlier we were using 2009 Q1 RadMenu and recently upgraded to 2011 Q1, but we are having some styling issues. What we did for newer version was just updated newer dll reference.

Do we need to to any thing while upgrading version in order to have same look and feel like earlier version.

Please suggest me.

Note: we were using customizing styles earlier.

Thanks
Tan.

Javascript Errors when displaying a Report Viewer...

I have a fairly simple page where a user selects report parameters, clicks a button, then a Report Viewer is displayed(visible=false on page load)...

I get this error after the user clicks the button:

Microsoft JScript runtime error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ctl00_MainContent_ReportMainContent_ReportViewer1_ReportViewer'. If it is being updated dynamically then it must be inside another UpdatePanel.

I know it has to do with the Report Viewer being invisible at first, but I'm not sure how to use RadAjax and still hide the Report Viewer until I am ready to use it? Below is the HTML and code behind for the button click.

Environment
Windows 7
Visual Studio 2010
ASP.NET 4.0
Latest Build for Telerik Controls(2011.1.413.40)
IE 8

thanks

Grid and GridNumericColumn thousand separator needed

Hello,

I have a RadGrid which has GridNumericColumns declared like this:

<telerik:GridNumericColumn DataField="Feb" DataType="System.Int32"

HeaderText="Feb" DecimalDigits="0" EditFormColumnIndex="0"

SortExpression="Feb" UniqueName="Feb" FilterControlWidth="50px" >

<HeaderStyle Width="80px" />

</telerik:GridNumericColumn>

It displays perfectly when in edit mode. It adds thousand separator. But, when Grid is in View mode, then it shows numeric value without thousand separator.

Is there quick and easy way to show thousand separator when grid is in view mode?

The same question would be for displaying numeric values in Chart series and axis when using Telerik.Reporting

Thanks
Tadas

Radgrid Export to Excel issue

Hi,

So I had Radgrid on my page full with data, then I am using Export to Excel method from Radgrid to generate excel file.
Then I save that file TestExcel.xsl on my computer.

The problem is : After that I am trying to open that saved excel file using connection, with that below, then it fires for exception.

_objXConn.ConnectionString = String.Format( _

"Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1""", _fullFilePath)

Exception:

System.Data.OleDb.OleDbException: External table is not in the expected format.

There is no issue with the code when i try to open some other excel files with that connection.
Why is this happening? Can you help me?
