C#

 m_ProjectMenu = new ContextMenu();
MenuItem MenuItem_Submit = new MenuItem();
MenuItem_Submit.Header = "Submit";
m_ProjectMenu.Items.Add(MenuItem_Submit);

MenuItem MenuItem_Delete = new MenuItem();
MenuItem_Delete.Header = "Delete";
m_ProjectMenu.Items.Add(MenuItem_Delete);

m_ProjectViewGrid.ContextMenu = m_ProjectMenu;
m_ProjectViewGrid.ContextMenuOpening += new ContextMenuEventHandler(m_ProjectViewGrid_ContextMenuOpening);

C#

void m_ProjectViewGrid_ContextMenuOpening(object sender, ContextMenuEventArgs e)
        {
           //here I want get menuitem by its header or name and set its IsEnable property to value I want

I don't know much about WPF yet, but try this and let me know if it works:

C#

m_ProjectMenu.Items("item_name_here").IsEnabled = true;

Hi Macro
unfortunately, it dose not work. Items a collection and only receives numbers as parameter.
