I have checkbox as the first column in my xamgrid. The checkbox is bound to the viewmodel. I am setting the default state of the checkbox to false. When i click on the checkbox, it checks and unchecks immediately. Vice versa for unchecking. This happens only the first time for that checkbox. If i check/uncheck the next time, it works as expected. Not sure, why the checkbox event fires twice during the first click. Could it be anything to do with rowselection? Appreciate your thoughts. Thanks!!
