dataset

Hello,

I have a DataSet with a DataTable having the columns Number and Description.

I do not want to bind both properties to a BindingSource bound again to 2 controls.

What I want is a 3rd column in the DataTable called NumberDescription which is a composition

of Number and Description. This property is bound only to 1 control/BindingSource`s property

not 2.

There is the partial XXXDataSet.Designer.cs file and the partial XXXDataSet.cs file. Of course I have defined the public string NumberDescription {get (doing some checks here;set (doing also some checks here} in the XXXDataSet.cs file.

But all this does not bind my new property/Column to the BindingSource the DataTable is bound to because the DataSet does not know the new column/property.

To make this new property/column known I could add a new column to the DataTAble in the DataSet designer view naming it NumberDescription. At least I see know the new property in the listing of the BindingSource so I can choose it. But all that did not help??

So how do I do that stuff properly? Should I call the NumberDescription Property in the Number AND Description Property ?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
