Setting dynamic connectionstring in aspx files is easy, for example :

"server=(localhost);uid=sa;pwd=; databse=" + database

But can i do this in Web.Config? I want to pass the value of the
variable "database" from aspx to Web.Config ad then set the dynamic
connectionstring there. Can i do that ? thanks a lot

Make the connect string as:

"server=(localhost); uid=sa; pwd=; database = {0}"

In Application_Load method (in global.asax) or whenever you get the
database name, create an application-scope (or whatever suits you)
variable by formatting the string. Example:

void SomeMethod(string databaseName)
{
string connstr = ConfigurationSettings["connectionString"];
connstr = String.Format(connstr, databaseName);

// now you can scope this connstr to your likes.
}
