after the checked event in the checkbox at the 2nd column inside the DataGrid called MyData
{ var u = from element in Mydata.Columns[2] where element is CheckBox select element; foreach (itm in u) { ((CheckBox)itm).IsChecked = true; } }

Since you have the datasource that bind to the DataGrid, if you set your DataField that bind to the CheckBoxColumn to True for your DataList, all the check box will be checked automatically.
Just remember, Silverlight is data centric. You can always change the data to change the UI. You do not have to access the UI control to change the Data.

You can set any control or composite control to the Column.Header.
If you do it in code:
StackPanel sp = new StackPanel();
TextBlock t= new TextBlock();
t.Text = "YourHeaderText";
sp.Children.Add(t);
CheckBox c = new CheckBox();
sp.Children.Add(c);
theColumn.Header = sp;

Hi i am also having the same scenario. when i am trying to put a checkbox in the Header i am getting an error saying "The Element is already a child" kind. How can i desing the XAML..

"The Element is already a child" means you are trying to add an element which is already in the visual tree. You can not add the same element more than once to the visual tree. Make sure your element has unique ID.
Also the code I provided (setting a control to the DataGrid.Header) no longer works since SL2 final release (it only worked in SL2 beta). You need to set a Header Template to define the header now.
