I more concerned about the look and feel of the grid. So i will not be interested to have RowDetailsVisibility as the look and feel is not as good as ChildTableDefinition, especially the expand and collapse button. not only that i dont see any option to expand all the rows at a time. I will appreciate if you could give me a workaround in ChildTableDefinition please.
Above is how i have implemented the hierachy event. and for the childgrid event on LOADED event i am assigning the ItemSource. So in this scenario please let me know how do i implement TAB control either at the design time or at the runtime.
If i am able to get access to the child grid at runtime, i believe I can implement TAB. I will try to set the focus when the Parent row looses focus to the childgrid. please advice.
