Binding of indexed property

    I am trying to bind child collection to FlexGrid e.g.
    public class MyParentClass {
    public string Id {get;set;}
    public List<MyChildClass> Children {get;}

    public class MyChildClass {
    public string Name {get;set;}
    <GridColumn Binding="Id" Header="Id" >
    for (int i = 0; i < 3; i++)
    int j = i;
    <GridColumn Binding=@("Children["+j+"].Name") Header=@("Name" + j) />
    But I cannot see anything except data in the first column
    Is this limitation of control or I made a mistake?
    Thank you

    The code snippet provided by you seems OK and it should work. We tried the same and it works for us with the build version: 3.1.20193.434.

    Please refer to the following code and the attached sample for reference.
    <FlexGrid ItemsSource="TreeItems" AutoGenerateColumns="false">
    <GridColumn Binding="ID"></GridColumn>
    <GridColumn Binding="Name"></GridColumn>
    @for (int i = 0; i < TreeItems[0].Children.Count; i++)
    <GridColumn Binding=@("Children["+i+"].Name") Header=@("Child"+(i+1)+" Name")></GridColumn>

    List<Tree> TreeItems = Tree.GetData(5);

    Just for information, assigning i to variable j is not useful in this case. You may avoid the line of code.

    Hope it helps!
