passing more then one value with the querystring with the same id

Question

I have a datalist that I want to list the Products that are comming from the Querystring. It works like this: Default.aspx/?ProductID=1 I get 1 product like I want

Answer 1

You can have:

/page.aspx?ProductID=1&ProductID=15&ProductID=25

Then Request.Querystring("ProductID") will return 1,15,25

This can then be put into an ArrayList like Request.Querystring("ProductID").split(",")

Passing those 3 values as a parameter is a bit more tricky though, youre probably best passing it as xml:

Passing multiple values for one SQL parameter
