If the selection mode of the Grid is different than row selection, no cell of the detailed grid gets selected. The bug is introduced with version 2016 R3 SP1 Steps to reproduce: 1. Run the following demo locally http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/declarative-relations/defaultcs.aspx 2. and add this configuration: <telerik:RadGrid ...> <ClientSettings> <Selecting CellSelectionMode="SingleCell" /> </ClientSettings>
Cell selection is not supported for hierarchy. It is not a bug, it was disabled for hierarchy, in SP1 2016, previously it worked unstable. https://www.telerik.com/support/whats-new/aspnet-ajax/release-history/ui-for-asp-net-ajax-r3-2016-sp1-version-2016-3-1018 Prior Q3 2015 the cell selection worked partially for hierarchy, but it was slow, even on the master grid. We did major rewrite.
Can you explain why this is not going to be fixed? This is critical functionality for our use of this control and which we have had to develop a workaround to provide the functionality that should be in the control supplied.
Could we please have some feedback when a fix is going to be supplied for this?
