voo’s solution was not working for me, ItemsSource was null, most likely because it was not directly set, but bound. All other solutions I found here at StackOverflow were dealing with sorting the Model only, but the DataGrid header was not reflecting to the sort. Here’s a proper solution based on the incomplete script here: … Read more
Ultimately I needed to do two things: Generate the columns manually from the list of properties returned by the query Set up a DataBinding object After that the built-in data binding kicked in and worked fine and didn’t seem to have any issue getting the property values out of the ExpandoObject. <DataGrid AutoGenerateColumns=”False” ItemsSource=”{Binding Results}” … Read more
Not using Mode=TwoWay for DataGridTextColumns solves one version of the problem, however it seems that this problem can appear out of nowhere for other reasons as well.

While / symbol is valid in DataColumn names, in has a special meaning in binding path and should be escaped if it is a part of name, e.g. [80/4] not 80/4 add event handler to AutoGeneratingColumn event in … Read more

DataTable columns (DataColumn) can be added/removed at runtime and DataGrid … Read more

Try use DataGridTemplateColumn. I created sample test class for databinding public class Test { public Test(string name, string attribute1, string attribute2) { Name = name; Attributes = new Attribute(attribute1, attribute2); } public string Name { get; set; } public Attribute Attributes { get; set; } } public class Attribute { public Attribute(string attribute1, string attribute2) … Read more
