I don't have an answer, but Google turned up this --
http://ndthangnb.blogspot.com/2010/04/systemwebhttpunhandledexception.html
-- which I suspect is a Web site of one of EPiServer's support staff (they're based out of Vietnam). No clear resolution, but it looks like a known bug -- #27295 -- which is fixed and will ship in the next version. I would open an official support incident to confirm.
Hi,
Yes, this is a registered bug and it has been fixed for EPiServer CMS 6.
Thanks for reply, I had read this earlier, but I am using Episerver 5.2 R2 and need some kind of work around or resolution.
May be re-defining/code property or handling / overriding any method might help. Can any one know details of the fix/where to fix.
I cannot upgrade solution as it is working for couple of years and no plan for upgrade. Need to deliver this for a very small enhancement.

Sorry for posting twice earlier, so the core issue is with Gridview and custom property. So if I use repeater or some other control then I should be able to save the value? If this is the case which control is best or not have issues with custom property?

Hi,
It seems you cannot fix it yourself. This change was made in the file EPiServer.UI.WebControls.PropertyDataForm.cs
/// <summary>
/// Load and translate tab headers.
/// </summary>
private void LoadTabHeaders()
{
_tabs.Clear(); //added
_tabs.AddRange(TabDefinition.List());
}
Where _tabs is a TabDefinitionCollection. You need a way to access that variable and call Clear(). But I don't think it's possible.
But I think the bug only relates to the specific control, ListView.
Thanks for reply, I found the work around. I use repeater in place of grid view. We had parent child controls, so I had to change on both controls. The great thing is with minimal changes this is working now.
Thanks for helping guys, keep the great work.

We have couple of custom properties. During saving of a custom property we are getting following error:
Multiple controls with the same ID 'EditFormBody0' were found. FindControl requires that controls have unique IDs.
This property is adding a user control to a update panel and allows user to multi select child page of certain types. I did not find any issue with code. Any help will be appreciated.
