SQlDataSourceParameterCollection error after upgrading to 5.3.12.119

[Ganesh Shivshankar]

Hi,

I just installed version 5.3.12.119 in my windows 7 machine. Now when I open reports which have a sqldatasource i get this error in the designer

"Object of type 'Telerik.Reporting.SqlDataSourceParameterCollection' cannot be converted to type 'Telerik.Reporting.SqlDataSourceParameterCollection'. "

Not sure how to fix this. I have restarted my machine and tried as well. Need help on this urgently!

Thanks.

Hello Ganesh,

Open the .resx file of the report as xml and delete the base64 encoded values i.e. delete the whole:

<data name="XXXXX_SQLDataSource.DefaultValues" mimetype="application/x-microsoft.net.object.binary.base64">
....
</data>

section. Close the report designer (if any open) and rebuild your solution.

HI Steve,

That worked! Thanks a ton. I hope this wont be a problem when opening this report in Windows XP machine or running it on Windows server?

Thanks.

Hi Ganesh,

You should not have any problem opening those reports on another machine.

All the best,

Great! Thanks Steve,

Just curious to know why this happened in the first place. Never faced this issue when upgrading previously.

Hi Ganesh,

This was a problem we have addressed in newer versions by utilizing the Upgrade Wizard.

Thank you! Similar/Same problem here with Telerik Q1 2015 / VS 2015 RC and no Upgrade wizard available (which I think wouldn't have solved our problem anyway).

Global search and replace solved the issue: <metadata.*DefaultValues" mimetype="application/x-microsoft.net.object.binary.base64">(.|\n)*?</metadata>
