I am currently using databing to show on an asp:label the result of
appending two database fields in the following way:
<asp:label id=textAcknowle dgedBy runat="server" Text='<%# DataBinder.Eval
(dataSetEventRe sponse1, "Tables[spEventDetails].DefaultView.[0].UserName")
+ " from " + DataBinder.Eval (dataSetEventRe sponse1, "Tables
[spEventDetails].DefaultView.[0].ComputerName") %>'></asp:label>
This works fine, but now I need to make it a bit more complex and check if
the UserName field is null and in case it is, display the name of the
current user (which is obtained from a session variable).
How can I achieve this?
Thanks,

Hi Jeronimo,
I dont think there is any direct way to give conditions for a Label..
One workaound would be like....
Write a function which takes 2 parameters and do all your validations and
checks here for the label control.
And let this method populate the label control...
Hope this helps...
Need any help, do post a msg back..
Happy Coding

You must set it in the Page_Load () event, something like:
private void Page_Load(objec t sender, System.EventArg s e)
if (! IsPostBack) {
textAcknowledge dBy.Text = ....
} else {
....
}
Inline databinding are only for the simple cases.

Jeronimo,
Instead of putting databind expression in the <asp:label... >, handle
ItemDataBound event. In the event handler you can implement any logic you
wish by using normal programming in C# or VB.

Thanks for all your suggestions,
Hi Jeronimo,
I think the two suggestions
1. Using a helper funtion (defined in page class) in your <%# %>
databinding template
2. Programly set the lable's Text in codebehind such as
lblName.Text = .....
are both ok. How do you think of them? If you have any further concerns or
questions on this, please feel free to post here. Thanks,
Steven Cheng

I am building the text for a resume section label in databinding with 20 or
so data columns using a series of 20 or so code snippits like the following:
If e.Item.DataItem("EmployerDisplay") And e.Item.DataItem("Employer") <> ""
Then
Sections.Text += "<BR><B>Employer</B>: " & e.Item.DataItem("Employer")
End If
Is this an efficient way to build the section label's text property? Any
suggestions?

Two-way databinding (as described in

works fine for me if I use it within aspx-files.
However, I would like to use it my codehind file and I don't know how
to get it work since I did not find any equivalent for "Bind" to use in
my ITemplate derived class.
For my ItemTemplate, I use
