Hi,

I have a TabControl with 2 tabs.
A Datagrid in each tab.
The first column header in each DataGrid is a CheckBox.
When the control display for the first time, i can see my checkbox in the header of the datagrid in the first tab selected.
Then, when i switch to another tab, my checkbox disappear.

Could you help me ?
