master-detail

The detail table does not update when you use a GridDataBoundGrid within a GridRecordNavigationControl for the master table.

I used a previous posted sample for a triple master detail and wrapped the master grid in a GridRecordNavigationControl (see form2 in the attached file).

All the grid's must use the same binding context. By default, a grid takes its bindingcontext from its parent. So, the master grid is using the recordnavcontrol's binding context, and the details grid is using the forms bindingcontext. so, try code like:

//set the grids
this.gridDataBoundGrid1.BindingContext = this.BindingContext;

this.gridDataBoundGrid1.DataSource = parentTable;

this.gridDataBoundGrid2.DataSource = parentTable;
this.gridDataBoundGrid2.DataMember = "ParentToChild";

Thanks Clay, that worked.
It is actually this.gridDataBoundGrid1.Binder.BindingContext in case someone is checking this out.
