I find a strange problem. In my current project, there are 3 radiobttons. After each button is clicked, the source of the grid will be changed. However i check the some rows can not be "showed". But when i click it, the value in it can be showed.
I think it is related with the refresh problem. So i invoke the UpdateLayout for the grid. i feel regretful it doesn't work.
Can someone help me to resolve it?
