Answer : asp.net I am trying to convert an html form into an aspx form or ? what ever. Need Help on how to to it.

yes. you have to get this error.

As Bind method is used only for binding data to data controls like gridview, repeater, datalist, etc.

If you have to bind dropdownlist  (or any other control) outside of these data controls then you have to explicitly set its value from code behind.

Like for e.g. when you are binding to dropdownlist.
at last you can set:

DropDownList3.Items.FindByValue("yourvaluehere").Selected  = true;
OR
DropDownList3.Items.FindByText("yourtexthere").Selected  = true;

Hope this clears you.
