GridPanel SelectedRows.Count always returning 0
I'm using Ext.NET 2.1, as retrieved through NuGet earlier today.
I have a window with a textbox and a button.
When I click on the button, a window pops up and shows a grid of data. The data is coming from an ASP.NET WebAPI, returned in JSON format, and this part of the process appears to work fine.
Eventually, the idea is that the user will double-click one of the grid rows, the value in the first column will pass back to the textbox, and the window will close.
At this stage, I'm just trying to get a count of the selected rows, after the user double-clicks a row. Given my RowSelectionModel Mode is set to "Single", I would expecta value of "1" to be returned when I double-click a row.
However, the code is always returning "0".
I'm new to Ext.NET, so it's probably something simple ... any help would be appreciated!
See code below:
