I have created a DataSet in my winforms c# project and data bound some user controls to a data table in it. I only use ReadXml and WriteXml to store the dataset in a local xml file, it is not database bounded.Nevertheless, it works just fine.
Later, when I add data columns to the data table I am unable to select those columns from data binding source's field list picker when want to bind it to a control.I have tried several things such as recreating the bindingsource component, recreating the dataset coponent on the form, but no success.
Maybe it has something to do with this behaviour and so it worth mentioning, that the solution consists of many class libraries, and the dataset is defined in one class library, while I have a form in another class library referencing and using that dataset via a data source. But everything works fine, I am just unable to extend the data table with new columns.
Any ideas ? Thanks.
