No AjaxControlToolkit.CascadingDropDownNameValue[]

1. Add DataSet TA_1.GetData() for dropdownlist_1

2. Add DataSet TA_2.GetData(_Label) for dropdownlist_2

3. Add Label.Text == dropdownlist_1.SelectedValue.

4. Add in dropdownlist_2_DataBound()

{

int _Label = Convert.ToInt32(Label.Text);

DropDownList dropdownlist_2 = new DropDownList();

dropdownlist_2.DataSource =TA_.GetData(_Label);

dropdownlist_2.DataValueField = "id";

dropdownlist_2.DataTextField = "Text";

dropdownlist_2.DataBind();

}
