Displaying Error against the wrong input in textbox

Question

I am working on a project that requires getting input from the user in a multiline textbox in WPF. I want to display an error message as soon as a wrong input is inserted and I want to display it on the side of the textbox. I have tried doing this by throwing exception but it's not displaying the error message on the display. Any suggestions how this can be accomplished?

I found the Solution:

Finf the Report web config in the below path :

C:\Program Files\Microsoft SQL Server\MSRS12.MSSQLSERVER\Reporting Services\ReportManager\web .config

Replace or add below line: to set admin credential for all users to access the report.

<authentication mode="Windows" /> // Authentication mode to be set to windows

<identity impersonate="true " userName="UserName" password="Password"/> // identity impersonate to be set to true and User name & Password of the SQL Server administrator should be added.
