Migrating windows forms from .net 1.1 to 2.0 (databinding)

[coh pat]

we are migrating our windows application from .net 1.1 to 2.0. we are using typed datasets to get the data from the data base. The text box cotrol binding is not working in .Net 2.0 applicationversion. The syntax is for binding to a text control is

textbox1..DataBindings.Add(New Binding("Text",Datatable,"columnName"))

The same code works fine in .Net 1.1 version. Can you tell me what is changed in the net2.0 framework for databinding a text control. The data binding for other control like drop down list, radio button works well.

Thanks in advance,
