title: In WPF, how can I allow only a single cell to be selected in a DataGrid?
body: <p>I want it to only be possible to select one cell in a DataGrid. With multi select disabled, you can still select a range of cells, but I want it to only allow a single-cell selection. Is there any way to do this through the properties? Or will I have to intercept the selection and filter out everything but one cell?</p>
