Hi all, I want to loop through the datagrid data to retrieve those records has been checked. Anyone know how to do this?

You were in the right path add IsChecked="{Binding Path=IsSelected, Mode=TwoWay}". Dont have the rest of the relative source stuff. Datagrid's itemsource will be searched for the property IsSelected; Make sure you have a property. On a separate note why aren't you using DataGridCheckBoxColumn.
