It would be nice if we can just bind a .net DataTable or DateView as ItemsSource to the RadDataGrid.
Programmatically changing column width does not reflect on the UI when the width value is lower than the current width value.
No issues when increasing the value, the UI is updated
Like in the WPF GridView control:

In case there are more columns inside the DataGrid, a horizontal scrollbar appears when a user swipes left. However, sometimes it' not clear there are more columns further on the left. For example, when you define a column's width with a big value or when the number of first 5 columns fit perfectly with a device's width totally by coincidence. In those cases, it'll be helpful to display horizontal scrollbar by default so the user knows there're more information on the left. (Very similar to a vertical scrollbar)
Currently, hiding the 'more' button in the of the DataGrid filter Options panel is not possible. This is a feature request to add such an option to the DataGrid column styling options (potentially as a property of the HeaderStyle).
Flicker can be observed when datagrid is manipulated/updated, or entering in edit mode. One example is tapping on a column header - when there is a column with a HeadetTemplate, the column header flickers. Other example is to double-tap a cell to go in edit mode. Also the behavior can be reproduced when DataGrid TemplateColumn is used.
