>Hi, I have been searching for this for quite a while and couldn't find a solution...
I have my aspx file and in it a asp:SqlDataSource, where I want to get values which are equal to the Request.QueryString["key"]. I have defined a parameter for it but I can't find the right syntax to set the value.
Currently it is looking like this:

<SelectParameters>
    <asp:Parameter Name="courseID" DefaultValue="<%= Request.QueryString["course_name"] %>"/>
</SelectParameters>

where I always get the error, it is not well formed. What is the correct syntax, and is there an article how you use this <%.. %> commands?
Thanks for your answer. Stefan
