Hi,

Im trying to implement this on one of my rad grids. http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/usercontroleditform/defaultcs.aspx

However this doesn't work and throws  a " 

Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.



Would anybody know a workaround this issue? The grid needs to be wrapped in an ajax panel due to the updates that it does while scrolling or filtering.  But i'd also would like to be able to edit entries usint that methodology or something that looks very similar.

Thanks
Rafal

Hi Rafal,

The specified message is not an error in your code as this is the Telerik trial message. It will stop popping up as soon as you upgrade to the Dev version of the controls.

The issue did go away. However now my row isn't highlighting when i edit it. I managed to add a javascript function to the edit button but i dont seem to be able to get the row element and hilight it. Can you by any chance point me in the right direction?

var grid = window["<%= grvTypeList.ClientID %>"];
 var masterTable = grid.get_masterTableView();
                    
                   
 //var rowControl = grid.RadGridTable.Rows[rowIndex].Control;
 //grid.MasterTableView.SelectRow(rowControl, true);
 //window.radopen("MiscTypeControl.ascx", "WebUserControl");

Found this on the internet but it doesnt work.

Thanks!

Hello Rafal,

Please refer to the following online demo which elaborates on the RadGrid Automatic Operations. I hope this works.

Hi,

I understand that that part of the radgrid is automatic but it isn't happening. there has been a similar thread on here that hilighted that issue but the solution posted there didn't work. Now there has to be  a way to highlight a row in java script but i haven't been able to figure it out. If you could help me out with that i would appreciate it.

Hi Rafal,

If I properly understand you what to mark the currently edited item as selected, right? If this is the case, you can handle the grid ItemDataBound server-side event and set the Selected property for the currently edited items to true.

Thank you Lana,

That did the trick!

Could you by any chance also help me out with adding a new item? I'm trying to open the custom user control when i add a new item. Unfortunately the demo page does not show an example of how to do that.

Thanks
