How to manage versions of items

[Mathieu Estratat]

Hi,
I am in front of a design problem : Is there a built in component available to manage the items version in a radgridview ?
A simple view of my problem is :
assume that you have 2 Classes
B with the following fields : string Name, string field1, string field2
A with the following fields : string field1, string field2 and BsField(which is a list of instance of B)

I want to display a list of A in a radGridView and display in the row details for each A the corresponding Bs in a grid following the parent grid design:
Suppose to have the following instances
b1('b11','b12')
b2('b21','b22')
b3('b31','b32')




a1 ('a1','a11','a21',{b1,b2})
a2 ('a2','a12','a22',{b3})

I want to have the following display :
      Name    |    field1    |    field2
-----------------------------------------
+    a1         |    a11      |    a21
-----------------------------------------
+    a2         |    a12      |    a22

with the corresponding display when the row details are open
      Name    |    field1    |    field2
-----------------------------------------
-     a1         |    a11      |    a21
-----------------------------------------
                   |    b11      |    b21
-----------------------------------------
                   |    b12      |    b22
-----------------------------------------
-     a2         |    a12      |    a22
-----------------------------------------
                   |    b13      |    b23

I guess this behavior will be managed by the next upcoming RadTreeListView component (2010 Q2 release), but I wonder if there is an other way to do that ?

Thanks a lot

Mathieu

Hello Mathieu,

 Indeed aligning columns in hierarchical / row details grid is not a trivial task and it will be better to use RadTreeListView in such cases. You can check our beta demo here:

Hi Vlad,
Thanks a lot for your answer.
So, we will have to wait for the RadTreeListView Component release ... Do you know when it will exactely be released ?
Is there a way to have this beta component ? In the latest build (RadControls_for_Silverlight_4_2010_2_0609_DEV) I did not find it.
Best regards
Mathieu

Hello Mathieu Estratat,

The official release or RadTreeListView will come with our Q2 2010 release which is expected in the first half of July.

As for its current availability it is included in our Q2 2010 Beta release (2010.2.609) in RadGridView assembly. To be able to work with it you need references to Telerik.Windows.Controls, Telerik.Windows.Data and Telerik.Windows.Controls.GridView.
