  Convert C# to VB

  Oct 26, 2009 10:33 AM|LINK

  Hi there i am trying to follow the book Apress.Beginning.ASP.NET.E.Commerce.In.C.Sharp.From.Novice.To.Professional with VB.

   

  I am in Chapter 4  and got the first problem:

  CssClass='<%# Eval("DepartmentID").ToString() ==

  Request.QueryString["DepartmentID"] ? "DepartmentSelected" :

  "DepartmentUnselected" %>'>

  this works in c# but not in vb, i get this errors:

   

  Error 1 Expression expected. c:\inetpub\wwwroot\UserControls\DepartmentsList.ascx 4 
  Error 2 Property access must assign to the property or use its value. c:\inetpub\wwwroot\UserControls\DepartmentsList.ascx 5 
  Error 3 Identifier expected. c:\inetpub\wwwroot\UserControls\DepartmentsList.ascx 5 
  Error 4 Syntax error. c:\inetpub\wwwroot\UserControls\DepartmentsList.ascx 6 
  

  thanks in  advance

  Look into using If().

  Hi,
  
  That is Ternary operator in C# and syntax will differ in VB. Use IIF
  
  CssClass= '<%# IIf(Eval("DepartmentID").ToString() =
  Request.QueryString("DepartmentID"),"DepartmentSelected",
  "DepartmentUnselected" %>'

  this.Fayaz();

  Hi,

  Also note that "=" is used for comparison not "==" .

  thank you all for your replys,

  but non of them worked for me.

  this is the Datalist: In C# project

  <asp:DataList ID="list" runat="server" CssClass="CategoryListContent" Width="200px">
    <ItemTemplate>
       »
      <asp:HyperLink
        ID="HyperLink1"
        Runat="server"
        NavigateUrl='<%# "../Catalog.aspx?DepartmentID=" + Request.QueryString["DepartmentID"] + "&CategoryID=" + Eval("CategoryID")  %>'
        Text='<%# Eval("Name") %>'
        ToolTip='<%# Eval("Description") %>'
        CssClass='<%# Eval("CategoryID").ToString() == Request.QueryString["CategoryID"] ? "CategorySelected" : "CategoryUnselected" %>'>>
      </asp:HyperLink>
       «
    </ItemTemplate>
    <HeaderTemplate>
      Choose a Category
    </HeaderTemplate>
    <HeaderStyle CssClass="CategoryListHead" />
  </asp:DataList>

  when i tryed the iif i got this error:

  Error 2 The server tag is not well formed. ./CategoriesList.ascx 5

  I believe the following will work:

   

  CssClass='<%# if(Eval("DepartmentID").ToString() = Request.QueryString("DepartmentID"), "DepartmentSelected","DepartmentUnselected") %>'>
