One of the most common questions on the net about ASP.Net, when coming from a Classic ASP background, is how to handle situations in which conditional programming is necessary. For instance, in Classic ASP, if you had this code:

If recordset("fieldName") <> "" Then
 ' do this
Else
 ' do this
End if

Since, in ASP.Net, we do not have the sequential code, coming throught the page, like it did with Classic ASP, sometimes we’ll have a label or textbox (or whatever), with the same field information which would have been previously contained in‘recordset(“fieldName”)’

.

To handle this, we would create a helper function, in our code section. So, in this case, let’s call the Function ‘CheckItem’. In the tag, we’d start with something like this:

<asp:Label ID="Label1" Text='<%# Container.DataItem("fieldName") %>' Runat="server" />

Next, we’ll add the code for the function:
