Hello,

thank you for the example. This providers a solution by declaring it in XAML. Can it also be done in code (c#)?

kind regards,

Hello Jonam,

There is no problem to define the calculated column in the code-behind. Thus following the example, that column would be like:

GridViewDataColumn calculatedColumn = new GridViewDataColumn();
calculatedColumn.TextAlignment = System.Windows.TextAlignment.Right;
calculatedColumn.DataMemberBinding = new Binding("Total");
this.gridView.Columns.Add(calculatedColumn);

You can find more information about defining columns in our online documentation.

Hello maya,

thank you for replying. In the online documentation you can find how to create columns with bindings to a value of an object but now how to bind to a calculated column. Do you know how this is possible?

kind regards,

Hello Jonam,

Please give us more specifics about your project. What is the purpose of binging to a column? Do you expect to get its values?

Hello Maya,

What i want in my project specified above and an answer is already given. I want column A to be a total of column B + C. The solution above works fine but i want to create the column dynamic in the code behind and not in the XAML. Do think this is possible?

kind regards,

Jonam

Hello Jonam,

I have prepared a sample project illustrating how to add the "Total" column dynamically on a Button-Click.
I hope that meets your requirements.
