   {  
     public long Appr_LeaveId { get; set; }  
     public string Appr_LeaveType { get; set; }  
     public int? Appr_RemainLeave { get; set; }  
     public DateTime Appr_FromDate { get; set; }  
     public DateTime Appr_ToDate { get; set; }  
     public string Appr_Action { get; set; }  
     public long Appr_EmpId { get; set; }  
     public int? Apply_Day { get; set; }  
     public string Appr_Status { get; set; }  
     private int apvNoOfdays;  
     public string Emp_Name { get; set; }  
     public string Emp_Department { get; set; }  
     public string Department_Name { get; set; }  
     public string Designation_Name { get; set; }  
     public long Apply_ID { get; set; }  
     public int Appr_TotalLeave  
     {  
       get  
       {  
         return this.apvNoOfdays;  
       }  
       set  
       {  
         if (value != this.apvNoOfdays)  
         {  
           this.apvNoOfdays = value;  
           NotifyPropertyChanged("Appr_TotalLeave");  
         }  
       }  
     }  
     private void NotifyPropertyChanged(string info)  
     {  
       if (PropertyChanged != null)  
       {  
         PropertyChanged(this, new PropertyChangedEventArgs(info));  
       }  
     }  
     public event PropertyChangedEventHandler PropertyChanged;  
   }

         </DataGrid>  

        

Cast the DataGrid With Class for Get DataGrid Value :

 List<ELeaveApprove> leaveApvList = new List<ELeaveApprove>();  
       for (int i = 0; i < approveDataGrid.Items.Count; i++)  
       {  
         ELeaveApprove eLeaveApproveObj = (ELeaveApprove)approveDataGrid.Items[i];  
         if (eLeaveApproveObj.Appr_Action == "Approve")  
         {  
           leaveApvList.Add(eLeaveApproveObj);  
         }  
         if (eLeaveApproveObj.Appr_Action == "Reject")  
         {  
           leaveApvList.Add(eLeaveApproveObj);  
         }  
       }  

Using leaveApvList you can also filter you datagrid value.
