Overriding items source of SfDataGrid.

I am trying to override the metadata of SfDataGrid with following code:
public class AdvancedGrid : SfDataGrid
ItemsSourceProperty.OverrideMetadata(typeof(AdvancedGrid), new FrameworkPropertyMetadata(OnItemsSourceChanged));
private static void OnItemsSourceChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
if (d is AdvancedGrid grid)
grid.HandleItemsSourceChanged(e.OldValue, e.NewValue);
Please note I have triedPropertyMetadata and UIPropertyMetadata too for passing in metadata details.
Everytime I am ending in exception:
{"Metadata override and base metadata must be of the same type or derived type."}

Hi Vasudeva 
We have analyzed your query to override metadata of SfDataGrid from our end. We have used GridPropertyMetadata type in our source for ItemsSourceProperty. Because of this only exception raises. So you can resolve this exception by using GridPropertyMetadata instead of FrameworkPropertyMetadata,. Please refer below code snippet  
public class CustomSfDataGrid : SfDataGrid 
        public CustomSfDataGrid() 
            ItemsSourceProperty.OverrideMetadata(typeof(CustomSfDataGrid), new GridPropertyMetadata(null, OnItemsSourceChanged)); 
        public static void OnItemsSourceChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) 
            //You can write your own code here. 
Please let us know if you need further assistance on this.
