Dynamic ASP button generation

Lloyd_Christmas · May 18th, 2005, 09:19 AM

I am trying to dynamically generate HTML content with VB in ASP.NET. Everything is wonderful except for the <asp:Button> which does not appear. I have read that I need to create an object and add it to the page. Sounds great except except I haven't found an example give me a more explicit idea of what to do. Any help would be greatly appreciated, code is included below.

<body bottomMargin="400" leftMargin="0" topMargin="0" onload="resizeTo(document.body.scrollWidth,documen t.body.scrollHeight)"
rightMargin="0" MS_POSITIONING="GridLayout">
   <%
   Dim Func As Integer
   Func = Request("Func")
   if Func <> 2 Then
        Func = 1
   End if
   Select Case Func
   Case 1
         Response.Write("<form runat='server' enctype='multipart/form-data' ID='Form1' ACTION='report.asp?func=2'>")
         Response.Write("<table align='center' cellspacing='2' cellpadding='2'>")
         Response.Write("<tr><td colspan='2'><H2>Report</H2></td></tr>")
         Response.Write("<tr><td>Main File</td><td><input type='file' runat='server' id='namefile' NAME='namefile' /></td></tr>")
         Response.Write("<tr><td>G1 File</td><td><input type='file' runat='server' id='g1file' NAME='g1file' /></td></tr>")
         Response.Write("<tr><td>I File</td><td><input type='file' runat='server' id='ifile' NAME='ifile' /></td></tr>")
         Response.Write("<tr><td>G2 File</td><td><input type='file' runat='server' id='g2file' NAME='g2file' /></td></tr>")
         Response.Write("<tr><td colspan='2' align='center'><asp:Button ID='cmdCheck' Text='Check' runat='server' OnClick='check' /><input type=""reset"" /></td></tr></table>")
         Response.Write("<asp:datagrid ID='DataGrid1' runat='server'></asp:datagrid>")
         Response.Write("<asp:label ID='l1' runat='server'></asp:label></form>")

       Case 2
          Response.Write ("Case 2")
   Case Else
          Response.Write("oh no")
       End Select %>

</body>

This is a completely incorrect approach to ASP.NET.

You can't Response.Write HTML that outputs markup of ASP.NET controls. The control markup has to be parsed by the ASP.NET process. By doing what you are trying to do you are sending HTML to the browser that looks like this:

<asp:button...>

The browser how no idea how to deal with this so it just ignores it. I think you need to go back to the beginning and get an understanding of the basics of how ASP.NET works.
