Web application slows down when changing data sets.

I have a program that operates on asp.net/vb.net web application. I have a portion of this program that runs a return of retrieving data for charting in the asp.net chart control. The initial running of the program works as intended, but when I repeat the process of selecting a different set of data parameters for the chart to display the program slows down.

Is this because of cache? If so how do I correct this?

Thanks in advance for the help.

Well, what does "the program slows down" mean exactly? Did you profile the server and the client side? Where do you have performance issues?

can you use filters rather than reloading the data from scratch ?

are you using data controls ?

Thanks for the replies. No I did not profile the server and the client side - don't know how to do that.

I don't know how to use filters. I am using data sources in the client side and changing the parameters of those sqldatasource parameters and the using chooses different input criteria (parameter values).

'the program slows down' means when I use the same drop down controls to change the parameter values I get a much slower response than the initial use of the drop down control.
