Is there any limitation on the size of the value of Parameter in sql server reporting services Report .

I am unable to pass Parameter value to the Report from the Web application if the value exceed 1600 chars.

I am using Web Application form's Post method to connect to report server and pass parameters. So The Query String limitation of 2040 chars is already been taken care.

My Report Execution simply hangs if the Report Parameter Value exceeds 1600 Chars.

Please help.

TIA
