This is a conceptual question...

I'm doing server-side advanced binding. My data source is stored in session state. The app allows a user to drill in on a particular row of the grid, which redirects to another page showing tons of detail not available in the grid. The detail page has previous and next buttons which allow the user to cursor through the rows that were displayed in the grid.

This works fine unless the user has resorted the grid. Drilling on the first record in the resorted grid, for example, gets me the original first record in the data source, not the data from the first row. (That is to say, DataSetIndex 0 no longer represents the same data as row 0 in the original data source.) It seems this is because the grid is using its own working copy of the data source I originally assigned. I could, of course, listen for sorting changes in the grid and resort the original data source along with what's happening in the grid, but that is a very inelegant solution.

What's a better way to do this?

export to PDF error

Hello all,
    I have done an example like the demo"export to PDF"http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/pdfexport/defaultcs.aspx
when i click my example,it download a RadGridExport.pdf,but when i open the RadGridExport.pdf,it can't open and tell me "打开本文档时发生错误。文件已损坏并且无法修复"(means that it damaged and can't repair)
when i open the demo's RadGridExport.pdf , it's all right.
I think that it is my code wrong, I don't know how to do.

Please suggest. thank you!

ASCX: The control requires a ScriptManager on the page.

so far - completely unable to get telerik Q2 2009 to work in MVC projects using any sort of encapsulation with ascx files.

Trying to use a combo box inside a ascx that is rendered with Html.RenderPartial.

Is this possible? Or do all the rad controls have to go in the aspx views?

Using LINQ datasource and FormView

First I must say, thanks for this new addition, defintely a nice to have feature.

However I am having some issues with it when not used inside a RadGrid as a BinaryImageColumn.

I took my existing app that used pictures on the file system and changed it to use images in the database using BinaryImage. My datasources are all LINQ Data Sources. My SQL 2000 table has a photo column of type 'Image'. I am using a FormView that gets it data from my LINQ data source.
Looking at your example you use a SQL data source and I would guess that it returns the Image column as a byte[] but when using LINQ my image column comes back as System.Data.Linq.Binary. This causes a 'Specified cast is not valid' exception.
My first work around was to change my Linq definition of my image column to type Byte[] and all works well. Except in another part of my app I use a RadGrid and the BinaryImageColumn it fails to work there. I believe its the opposite issue that it's expecting the other type.
I would prefer to leave my LINQ definition to have the default Image column as a System.Data.Linq.Binary and deal with the casting issue.

Can someone tell me the syntax of how to cast between Byte[] and System.Data.Linq.Binary in the aspx page or do I have to do it in code behind?

Thanks,

Perry
