DataBind based on Parameter

I have a DataSource assigned to a DropDownList (DD2) that has a WHERE clause specified by the contents of another DropDownList (DD1). When I change the DD1, however, that DD2 does not reload its data. Is there a way to get DD2 to reload when DD1 is changed?

I've tried:

protected void DD1_SelectedIndexChanged(object sender, EventArgs e)
{
    DD2.DataBind();
}

But this appears to do nothing.

Move the logic of setting the DD2 DataSource and DD2 DataBind() to a new function and call that instead. Your problem is likely that the datasource is getting incorrectly set.

protected void DD2Bind()
{
    DD2.DataSource = //fetch data source
    DD2.DataBind();
}

protected void DD1_SelectedIndexChanged(object sender, EventArgs e)
{
    DD2Bind();
}
