The disappearance of the child template

[Jasper]

Hello there,

I believe I've found a bug in gridview. After adding a childtemplate (1) to a childtemplate (2) of the mastertemplate, any change to the grid will 'disconnect' childtemplate (1) from childtemplate (2).

To work around, add the following in your *.designer.cs after the changes:

this.gridTemplate2.Templates.AddRange(new Telerik.WinControls.UI.GridViewTemplate[] {
    this.gridTemplate1
});

Of course, this is incredibly annoying to do every time you change the grid, so I'm hoping another solution is possible.

Hello Jasper,

Thank you for writing. 

We have a similar issue logged in our feedback portal. You can track its progress, subscribe for status changes and add your vote/comment to it on the following link - feedback item.

Currently, the possible solution that I can suggest is to setup the hierarchy programmatically :  http://docs.telerik.com/devtools/winforms/gridview/hierarchical-grid/binding-to-hierarchical-data-programmatically

I hope this information helps. Should you have further questions I would be glad to help.
