Answer 1

I have added CheckBox to Select all CheckBox in Datagrid Row

if you mean select all checkbox in datagrid column, then i would say: simply update your itemssource collection with checked/unchecked.

public bool SelectAll
{
  get{return this._selectAll;}
  set
  {
     this._selectAll = value;
     this.MyItemsSourceCollection.ForEach(x=>x.MyRowCheckProperty=value);
     this.OnPropertyChanged("SelectAll");
  }
}

xaml

i dunno if the xaml bindings are right, but i hope you can see my intention
