I have a grouping grid filled with rows of information where a 'Status' field may be different from row to row. Based on the value of the Status, I may have no items in a context menu or I may have one or more different items.
I want to use the new record-based selection code so my grid settings are as follows:
I catch the grid mouse click event and if it is a right mouse button, I fall through the code to 1st clear the current context menu, then resetup the context menu based on the status values in the row(s) selected.
This all works fine if I click on the ROW HEADER. But if I click on the Row Header and get a context menu item with A, B, and C menu items. Then I left-click on a cell in a different row; the row appears to be selected just fine; I fall through my code and I can see that the grid's context menu is being cleared but the context menu with A, B, and C still appears.
I found a support note on another grid-vendors site (Infragistics) that addressed a similar problem. They stated that the context menu was assigned to the underlying textbox on the grid so they provided code to clear each cell's context menu.
I see nothing remotely similar in the Syncfusion Grouping Grid but I'm guessing the problem is something like this.
How do I force the grid's cell to realize that a new Context Menu has been assigned to the grid and to use that one instead of the 'old' one?
Once again - all works fine if I click on the Row Header and not in an individual cell.
Note - to clarify my previous message. I left-click in a cell on a different row and the row appears selected. Then I right-click to bring up the context menu and it falls through my code ...
(I wanted to clarify that I do a left-click to select the row; then a right-click to show the menu).

Not exactly the behaviour I was after but I worked around the issue. The users must right-click in the row header in order to get a context menu. Using the options specified in this thread, the behaviour was not consistent.

I finally achieved the behaviour I was after with the following:
Catch grid TableControl Mouse Down. In that Event, clear the grids context menu. If the button is a right-click, resetup the context menu.
The clearing of the context menu appears to work ok.
