Question

I have a structure that looks following

Class TreeNode  {
    public TreeNode Parent { get; }
    public IEnumerable<TreeNode> Children { get; }
    public . . . . 
}

I want to bind this to a asp.net telerik radgrid with detail tables for each level of the children. I know that radgrid supports declarative binding to a self referencing hierarchy using a datasource control but that assumes you have a flat dataset (e.g. from a database) and can look at a parent key field of some sort. My question has anyone bound a radgrid to a data structure like this before and is there a way to do it declaratively or mostly declaratively?

Answer 1

I can t answer your question directly since I ve no experience with the telerik grid, but I can offer a work around.

Add a method to your class that flattens its contents into a self-referencing table like structure such as the one you mentioned. This way you can still work with the class and it s more advanced structure like you want to, but can still output the contents in a consumable form that matches the expectations of the UI components.

This is also a good candidate for an extension method too.

Answer 2

Another possible way I can think of is to build the hierarchy dynamically by filtering the date for the child tables based on their parent inside the DetailTableDataBind grid handler. This demo is a good reference:

but I must agree that Stephen s suggestion might be more handy.
