I've been working with Telerik RadGrid, MasterTableView an I tried to export my data to Excel but with no success. The file is created and saved on my workstation but the file is not of "Excel" kind.

When I open the file it only contains HTML. Is this right? Excel says that the file is not of any correct Excel type!

Update: This error only occurs when you use "Excel Viewer" due to the fact that "Excel Viewer" can't convert the outputed HTML file to a "real" Excel formated document.

Is there anyway to get the output as a real Excel document not a invalid document in HTML?

Hi Telerik

Hi there
   I just want to report a bug i experienced to telerik team. When using Telerik Reporting Chart Control, visiting the Properties dialog box and get into the Lables,Legent & Title, if the Series dropdown value is changed the Chart Build dialog is closed abrubtly.

Software Configuration
Visual Studio 2008
Telerik Reporting Q1 2009 trail
Windows XP OS

Hi There
   I'm having a datatable prepared from the business layer and i need to use that for report parameters. But i am having hard time binding a column in that parameter.

Consider that i want to bind the (ProductId, ProductName) first & second column of the datatable to this report parameter and i want it to show all the row data as a multi value

But as soon as i add this binding, and while executing the report gets empty and not even shows the rest of the report and when i remove the parameter addition and just binds the report and render all the data

I tried a work around to show the dropdown parameter in report viewer by doing the below code snippet instead.

And now it shows the report and also the report parameter dropdown but with all the product name separated by semicolon in the value as it is coded to set as value (not as datasource) but i can only edit them but instead i want it to be a set of checkbox in the pulldown box of dropdown so that user can easily select them (as it would appear when i assign the datasource in design time).

Software Details

• Windows XP sp2
• Telerik Reporting Q1 2009
• Visual Studio 2008

Please guide me a way to assign datasource to parameters dynamically. Thanks in advance. I greatly appreciate a sooner response.

Will the release version support Medium/Partial trust?

Thanks,

Brian

I'm using Asp.Net AJAX UI controls to display a RadGrid on a page with a ReportViewer underneath.  When the user selects a row in the RadGrid I want to capture the ID field from the selcted row and update the ReportViewer by passing that same ID to the newly instantiated report.

Has anyone done anything like this?

I can capture the needed ID from the client-side of the RadGrid, but I can only update the ReportViewer on the server-side.  I guess if I knew how to capture the RadGrid selected row on the server-side I could manage just fine.

i set up a new development machine and now i am getting the following error when i try to open the design view of a report:

Value cannot be null. Parameter name: instance

the sources, assemblies and web.config is all the same as on the other machine where it works.
i tried to rebuild the project, restart VS2008 but nothing helps.

any hint would be highly appreciated
regards

Viewer is not showing up Parameters if div is initially set display = none

 

 

 

 

Hi,

I'm getting an exception when I close the form containing a report viewer,
while it's generating the report.
On slow machines, the generating of the report can take some time,
and users might close the form before the generation is completed.

How should that exception be handled ?

Thanks,
