YSOD: URL Picker inside DataType Grid

description

Hi,

I recently upgraded to uComponents v5.5.1 on umbraco v4.11.8 and now get the following exception from pages with my DataType Grid added:
The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I've got a pretty complex DataType Grid with images, text and URL pickers in. It seems if I remove the URL picker from the grid then it stops the exceptions happening... but I really need the URL picker in there!

Any suggestions for a workaround/fix?

Cheers,

Paul

We've also got this issue with v5.5.0 & v5.5.1 on a few versions of Umbraco (4.11.10, 6.1.3 & 6.1.4)
Again, this only occurs when we add a URL Picker to a DataType Grid.

Wow I didn't know the URL picker could be used in a DTG...

I have no idea why this is happening, perhaps you can supply a longer stack trace?

Hello,

I also reproduce it in Umbraco v6.1.3 and uComponents 5.5.1

I created a new bug - https://ucomponents.codeplex.com/workitem/14870

Can you try installing version 5.5.2-build010 and see if it solves your problem?

Run the following commands in your Package Manager Console:

Install-Package DiscoverPackageSources
DiscoverPackageSources -Url "https://www.myget.org/F/ucomponents/"
Install-Package uComponents -Version 5.5.1-build010

I have 5.5.2 uComponents from NuGet in Umbraco 6.1.5 and still get this error.

My bad, I upgraded from 5.5.1 to 5.5.2 but the assemblies weren't overwritten before I tested. The error is fixed.
