MVVM - How to create columns at runtime for a xamdatagrid?

由 假装没事ソ 提交于 2020-01-01 05:01:07

Infragistics XamDataGrid with variable number of columns

由 懵懂的女人 提交于 2019-12-23 20:56:54

I have a typeconverter which will convert the data stored in a custom class to a label or textblock containing several text elements with different colors. The data is provided in a datatable (any method that works will be fine) and each value is correctly applied to a cell. The

问题 In a True MVVM model we do not expect any code behind in xaml.cs also we do not expect viewModel to have refernece of view.
