Parameter that filter on another parameter

[Andreas Selling]

Hello

I have two parameters that hava a datasourse. The second one has a filter on the selected ID on the first parameter.
When I run the report in a browser with reportviewer and select a value on report parameter 1. The report seems to do a posback and all parametersfields dissapear.

I run Q1 2010 SP1
C# 4
Integrated mode.

This worked in previus versions of report viewver. Eiter way its the c# 4 uppgrade or the upgrade of the telerik reporting to q1 that is causing this problem.

Any ideas?

I sent Telerik a support ticket instead.

Set RequestValidation to 2.0 in web.config and it solves it.

Hi guys,

This is a breaking change in .net 4.0 which causes additional validation for the values in the parameters page. We will provide a fix for this change in the next release or internal build. For the time being you can solve the problem by adding following entry in the web.config file:

Copy Code

<httpRuntime requestValidationMode="2.0" />

You can find additional information on the change in the following blog post: RequestValidation Changes in ASP.NET 4.0.

All the best,
Steve
