Hi,

I created a SSRS report using RDP class and Contract Class And UI builder class.

I want to open it by creating a dialog box .I created the menu Item for SSRS report and I tried to open it .

But at that time I found an error and I am not able to open it.

The error is-

“Contract class Map should have a public constructor with no arguments.”

Please give me some solution.
