How to copy one row and paste it into all the selected rows like Excel in the SfDataGrid?

this.sfdatagrid.GridCopyPaste = new CustomCopyPaste(sfdatagrid);
…….
public class CustomCopyPaste : GridCutCopyPaste
{
    public CustomCopyPaste(SfDataGrid sfgrid)
        : base(sfgrid)
    {
    }
    protected override void PasteToRows(object clipboardrows)
    {
        var data = (IList)clipboardrows;
        //Gets the ClipbordText and check if the clipboard text is more than one row
        //means call the base.
        if (data.Count > 1)
        {
            base.PasteToRows(clipboardrows);
            return;
        }
        //Gets the Selected records for paste the copied row.
        var selectedrecord = this.dataGrid.SelectedItems;
        for (int i = 0; i < selectedrecord.Count; i++)
        {
            var selectedRecords = selectedrecord[i];
            // Calls the PasteToRow method with copiedrecord and selectedrecord
            PasteToRow(data[0], selectedRecords);
        }
    }
}
