Parameter Values and Refresh method

[deeparajesh]

I am passing a single parameter in a reportviewer and I have a timer in VB to refresh the report data.In the timer I am calling the refresh method. The problem with Crystal reports is that it prompts for the parameter value each time.Using Enableprompting property I disabled the request for prompt and also have set the default value. But still it does not take the initial value assigned, it takes the null value.

What I need is, it should use the initial value and should not prompt for the parameter each time and still I have to refresh the data for a specific time interval.

Pls. reply immediately .
