Invalid postback or callback argument error

[Chom]

Hello

Could someone help me with this problem. I have 3 grids on a page. I am adding categories to grid 3 (category grid) base on what row is selected in grid 1 (lisitings grid). If I have 3 listings in grid 1 (listings grid) and have added a category to grid 3 with listing 3 selected. When I go and click on listing 2 in the listings grid to add a category for listing 2 I get this error.

Error:-

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

I have tried changing things in the ajax manager and different methods to get the data from the db, but am still having the same problem. In fact after I have added 1 category to grid 3 when I click anywhere on the page I get the above error.

Hi,

I have noticed from your design that  you have used both  RadAjaxPanel  and RadAjaxManger. The Telerik team has documented this error stating the cause to be the  use of both the controls at the same time .Please  take a look at the link below :
Receiving Sys.WebForms.PageRequestManagerParserErrorException

Hi Princy

Thanks for your help. I have removed the ajax manager and have wrapped an ajax panel around everything in the page. All is working well however the binary image upload in the 2nd grid is causing some errors.

I used the RadAjaxPanel1 that was wrapped aroung the rgSlides grid. This call a javascript event and is the code used from the RadBinary image example http://demos.telerik.com/aspnet-ajax/controls/examples/integration/raduploadinajaxifiedgrid/defaultcs.aspx?product=binaryimage

Here are some images of teh problem. when the grid is in EditMode I used a popup window to add the images and I have also changed the grid to Edit Forms. However the problem still persists. I captured a screen shot of the problem. What happens is when I mouseover the Select button a text box with a browse button appears and when i click on the Select button to open the dialog to upload a file, the dialog doe not open.
