Hi all

iam using Asp.net2.0 , c#,sqlserver

Now i ran the application on server  it does not give effect.

if i go to reportserver and uploaded the RDL  then it is working nice.

But my client dont want to  upload every time if i modified RDL's

how can i get (latest result of modified RDL) on server
