DataBinding ListBox.DataTextField

[musosdev]

Hi guys

I have an asp:ListBox on my form, which I'm populating with a DataReader,
using DataSource/DataBind.

The problem is that the main field I want to use for DataTextField,
"Company" in this case, is often blank. How can I get the DataBinding to
go...

"if Company is blank, use ContactName, else use Company"

...is that even possible? Or is there a way I can do this in the SQL somehow?

Hope that makes sense!

Cheers

Dan

Dan,

You can do it in the select:

select ... case Company when null then ContactName else Company end as
CompanyName...

Hi Dan,

ListBox is a simple databound control which doesn't support itemdatabound
event like repeater or datalist. So if you want to do it in ASP.NET layer,
you can consider programmtically loop through the datareader and populate
the listbox instead of using databinding. Also, for T-SQL layer, you can
have a look at Eliyahu's suggestion and you can also try posting in
SQLServer. programming newsgroup since there're many experiences SQL guys
there.
