Why are so many Controls Have a Red Line under it

Here is just one example:

OrderSummaryControl.BindData();

Click on the line Gives me the following

The name 'OrderSummaryControl ' does not exist in the current content

The Control still works as does all the other with redlines and the desiginated help msg of
The name 'OrderSummaryControl ' does not exist in the current content.

But it does not help if I am trying do use the control like in

string t5 = (String) OrderSummaryControl.FindControl("UxQuantityText").ToString();
here I have a red line under OrderSummaryControl and the help msg
The name 'OrderSummaryControl ' does not exist in the current content.
