  I am trying to bind child collection to FlexGrid e.g.

  … public class MyParentClass { public string Id {get;set;} public List Children {get;} }

  public class MyChildClass { public string Name {get;set;} } … 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

  Hi, 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">
      <FlexGridColumns>
          <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>
          }
      </FlexGridColumns>
  </FlexGrid>
  
  @code{
      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!
