In my case I had to set MaxHeight and replace IsEnabled  False  by IsReadOnly  True

Put the DataGrid in a Grid  DockPanel  ContentControl or directly in the Window  A vertically-oriented StackPanel will give its children whatever vertical space they ask for - even if that means it is rendered out of view

Adding MaxHeight and VerticalScrollBarVisibility  Auto  on the DataGrid solved my problem

Add  grid with defined height and width for columns and rows  Then add ScrollViewer and inside it add the dataGrid

This worked for me  The key is to use   as Row height    lt Grid x Name  quot grid quot  gt           lt Grid RowDefinitions gt               lt RowDefinition Height  quot 60 quot   gt               lt RowDefinition Height  quot   quot   gt               lt RowDefinition Height  quot 10 quot   gt           lt  Grid RowDefinitions gt            lt TabControl  Grid Row  quot 1 quot  x Name  quot tabItem quot  gt                   lt TabItem x Name  quot ta quot                           Header  quot List of all Clients quot  gt                           lt DataGrid Name  quot clientsgrid quot  AutoGenerateColumns  quot True quot  Margin  quot 2 quot                             gt  lt  DataGrid gt                   lt  TabItem gt           lt  TabControl gt            lt  Grid gt

If any of the parent containers RowDefinition Height set to  Auto  also stoppers for scrollbars  Alternatively you may set Height      Which happened in my case
