Hello, Telerik, I have a question to you regarding the hierarchical RadGrids.
I'm using a hierarchical RadGrid (Telerik control) but there are some bugs regarding the sort of the second level. I have two levels and the second level is loaded based on the first level.
Columns of the first level: Foo1, Foo2, Foo3
Columns of the second level: Bar1, Foo2, Bar2, Bar3
Binding is issued through a function.
If a single row of the first level is expanded (we can see a single sub-grid from the second level) and I want to sort by Bar1, the sort happens, but an error occures:
Uncaught TypeError: Cannot call method 'sort' of null
If a single row of the first level is expanded (we can see a single sub-grid from the second level) and I want to sort the second level by Foo2, the sort happens for the parent grid's (!) Foo2 column
If two rows of the first level are expanded (we can see two sub-grids from the second level) and I want to sort both the subgrids by the same column a strange rectangle appears instead of the ascending/descending sign, I get the same error as described in the first problem but the sorting is not issued.
I would like to get rid of these problems, my question is the following:
If we have a hierarchical RadGrid and both the first and the second level is sortable how can I implement a sort of the second level to be free of bugs?
Thank you in advance for your responses.
