[Solved] build an hierarchical grid with nested detail out of a class instance

[Marcel Keller]

Hi there,

with Telerik it is rather easy to bind a custom class to a radGrid. But for now I do spend hours of research on how to visualize the hierarchy of my class!

Let's assume, we're having this class structure:

class MasterRecord
{
    public string Title { get; set; }
    public string Description { get; set; }
    public List<SlaveRecord> SlaveRecords { get; set; }
    public SlaveRecord SingleRecord { get; set; }
}

class SlaveRecord
{
    public string Title { get; set; }
    public string Description { get; set; }
}

If I bind a list of <MasterRecord> to the datasource, all my entries show up in the grid (two columns: Title; Description ), but I can't manage to show up the SlaveRecords or even the SingleRecord!

I've tried a lot of stuff so far, but nothing gets it to work as expected. If I'm in the context of a NestedViewTemplate I'm able to Eval() on the current child, but it doesn't get connected with another radGrid.

Hope, someone could help me here, as all i want to achieve is a basic property grid / property editor.

Hello,

In order to achieve your goal you should define first the nested TableView and then assign a datasource to it. You could check this online demo application which illustrates similar approach.
