Problem With TFS Reports Parameter Change

When we Change an Existing TFS 2010 Report and  upload it to the ‘TFS report site’ in order to add it to a specific team project (How to Add TFS 2010 Report to a Team Project) we many times want to change the default parameters of that report.

If you try to add default values of a parameter it should work when you’ll upload the new report to the report site and you will see the changes. if you try to delete one of the default values, when you upload the file you will not see the changes.

The reason for that is that the parameters are global (can be used in more then one report) which is why by default you are not let to deduct any default values from the parameters.

Solving this is easy; simply delete the original report before uploading the new one, that way the parameters will be uploaded with the report exactly as you constructed them in report.
