Help for right syntax in .net for defining variables in web pages

User 2512513

I am trying to create a website in asp.net with multiple navigations links. A sample of the same in .asp is: Define a variable on the homepage: <% Dim varSection varSection = Request.Form("varSection") If varSection = "" Then varSection = "Home" End If%> And then call frm an include file as: <% If varSection = "Home" Then %> Display this content <% End If %> <% If varSection = "Abt" Then %> Display this content <% End If %> Likewise, I seek help with the right syntax in asp.net as above. Currently my homepage in asp.net just has the following code: <%@ Register TagPrefix="MY" TagName="top" src="includes/top.ascx"%> <%@ Register TagPrefix="Page" TagName="left" src="includes/left.ascx"%> <%@ Register TagPrefix="Header" TagName="right" src="includes/right.ascx"%> <%@ Register TagPrefix="Hdr" TagName="bottom" src="includes/bottom.ascx"%>

You can do it in many ways, the simplest would be to do it with javascript. Just add the contents in div tags, set the display property on the click of the links using javascript.

As Dinesh said, there are many ways to do this. Unless design considerations make it too difficult, my preference is to use HyperLink controls on the page and set their properties in the page's PreRender event:

Protected Sub Page_PreRender(ByVal sender As Object, _
ByVal e As System.EventArgs)
Dim varSection As String = Request.Form("varSection")

Select Case varSection
    Case "Home"
        With Link1
            .NavigateUrl = "Go here"
            .Text = "Home"
            .ToolTip = "Go Home"
        End With
        Link2.Visible = False
        Link3.Visible = False

     Case "Abt" 
        'Etc.
End Select

End Sub

Another way of doing it would be to put static links on Panel controls, with only one visible depending on the value of varSection. When the page gets rendered, controls with no visibility are not added to the output stream so you don't need to worry about adding bloat. Can't help you with @Register as I've never had to use it. Our registration info is in web.config.

Thanks Dinesh for the reply. It would be really helpful if you can provide me with a sample code in review of the .asp code I submitted. I am a just a newbie & not well-versed with the correct syntax.

Thanks Greg. From my query i initially submitted, I am looking out for a similar logic towards wht you stated @ putting static links on Panel controls & toggling b/w on-off visibility. Request you to provide with the correct syntax of the code to be used.
