Debugging RadGrid postback problems

This is kind of a general issue for a lot of different problems I've had when working with RadGrids. If there's some sort of error in the code, I've been having a difficult time (in many cases) trying to figure out what exactly the problem is. In particular, if some sort of error is introduced that affects the edit/insert mode, my only sign that something is wrong is that the edit/insert buttons stop working and the Firefox error console reports something like the following:

                    Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.         
            Details: Error parsing near 'ý         
            Source File: http://eon2.actteleservices.com/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_RadScriptManager1_TSM&amp;compress=1&amp;_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d4.0.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-US%3a8f393b2b-3315-402f-b504-cd6d2db001f6%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2010.1.309.40%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-US%3aa491094c-5dfe-45a9-a72f-e5f5f0640d11%3a16e4e7cd%3aed16cbdc%3af7645509%3a24ee1bba%3ae330518b%3a1e771326%3a8e6f0d33%3a58366029%3aaa288e2d         
            Line: 15         

Is there any way to get more specific errors for RadGrid postbacks? Is there some logging that I'm not aware of that might help to isolate the issue? I'm usually reduced to guessing at this point until I manage to hit whatever the problem is.

ISSUE WITH APPOINTMENT STYLE

The appointment background style in the scheduler is not rendered when I navigate from (say) monthview to dayview. The style gets reflected only for the first time when I create the appointment. The code for applying the background color is written in RadScheduler_AppointmentDataBound() handler. Any help in this regards is appreciated.

URL Routing with Telerik

Hi..

I'm just wondering.. How can I implement URL Routing with Telerik using GridHyperLinkColumn?

We're kinda new to Telerik so we can't really go around it ourselves. =)

Thank you, in advance.

Hierarchical RadGrid Calling Data Source Multiple Times

I have a RadGrid that is contained within a RadTabStrip/RadMultiPage/RadPageView. This grid consists of a MasterTableView and two detail tables. The data source for the grid is an ObjectDataSource and is being set in the OnNeedDataSource method. The user enters a date range and clicks a button to populate the grid. The button click event fires the grid.Rebind method. The Rebind fires, calling the OnNeedDataSourceMethod. After this method fires the select method of the ObjectDataSource gets called three times.

Is there a reason it's hitting the database three times? Is there a way to get around this? The dataset returns fairly quickly, but pulling it back three times is slowing down the load of the grid.

[Solved] Display Additional Columns from SQL table on top Of a Rad scheduler cell

Hello Telerik Team,

I have a requirement where i need to bind the scheduler to a sql database table and display some columns
from the table on top of the cell.I mean by default scheduler just shows up the subject on the cell but i wanted to display some additional columns from database example priority column, Description column,etc on top of each cell instead of the edit template.At the same time i need to colour code the cell based on the status column values.

I have connected the scheduler to sql datasource already and able to fetch the information.

Any pointers in this direction are greatly appreciated.

Thank you
Smith
