Child relation sorting for the DataSet in C#

[anujsharma181]

Hi
I am trying to sort the child table.
Here's the complete scenario. I have used web services to get values in the data set. There are 2 tables T1 and T2 for data sets and they have a parent child relationship . T1 is parent and T2 is the child. Now I am retrieving all the values of T1 in grid 1( using dataviews) and T2 (child)( Also using dataviews)will contain only the values associated with T1(Parent). I have used data binding for that and I have used WPF (Windows Presentation Foundation) for developing my UI and C# is my back end code. I have 2 grids , grid 1 contains values displayed by d1 and grid 2 contains values displayed by d2 but only associated with grid 1. Little tricky scenario. I am trying to sort the dataview d1 (which contains T1's values in g1). Since T1 is the parent, I would be able to sort d1 and it also displays all the values associated in T2's data view d2. I apply d1.sort() and it does work.But My problem is that when I want to sort the d2 (which has child relationship), it does not work. I could not figure out how to sort the child values in the data view. I want to sort the child items in grid2 and moreover I want the grid 1to display the values associated with the grid 2. Thus binding should remain and also sort should be done on the child relationship. Please help me out.
Thanks a lot
