Server error control 'btnSubmit' of type 'Button' must be placed inside a form tag with runat=server.
I created a form in asp.net using vb.net code the form consists of a button(btnSubmit) a textbox (txthistorialprices) and and a dropdownlist (ddlStocks). When the user selects an item in the dropdownlist and clicls the submit button, thw code in the submit button should open a sequential file containing the same name as the symbol with the file suffix of .txt.. I have put three files in s shared file called C:\share. When I run the solution I get this error: Control 'btnSubmit' of type' Button' must be placed inside a form tag with runat = server. I new at this stuff and have no idea what I did wrong. Here is all my code:
