In this line:

        mail.Body = "Category:" & " " & DropDownList3.SelectedItem.Text 

You send only the category, you need to add the other information to the Body.

I do not know the names of the fields on your form but you need to change it to something like this:

        mail.Body = "Category:" & " " & DropDownList3.SelectedItem.Text + "<br>" + "Name: " + txtName.Text
