How to save parameter in a variable frmURL even though thepage get refrehed

Hi,

I am facing a problem related to web template creation.

I am creating a template where I am redefining the print and download function in the java script. The business scenario is The web template is it will contains a parent hierarchy node of a region and display a table with some characteristic and key-figures based on the region. If you click the print or download to Excel link. it'll open a new template and display the table value into that and then pop-up the print dialog box or get downloaded to Excel.

The problem is I want to pass the DATA_PROVIDER_ID = some view name in the URL. I want to store the DATA_PROVIDER_ID into some variable and then pass it to the new template. It's working fine for the parent hierarchy region. But when I am selecting some child or leaf node for the filter value, the page get refreshed and the variable also get refreshed. There are 4 views. Then how to pass the DATA_PROVIDER_ID for the filter values. Please let me know how can I approach for that. It's urgent.

Deep.
