hi all..

I'm trying pass a DataTable from Class A to Class B [Here I'm using 3-Tier architecture class b is in class library] using properties my code goes like this.


1)public  DataTable TYPE_TYRE()

In the above method(1) I'm using to bind the grid to DataTable  (working fine)

Case1:-
2)  protected void Test_Click(object sender, EventArgs e)

  {
  Vehicle_Bal ObjB = new Vehicle_Bal();
  ObjB.DtTyre = TYPE_TYRE();
  ObjB.BlTest();

  }

In (2) Button Click I'm Calling (1) assigning it to property from Class A to Class B everything is working fine[Case1 when testing] i could get data in to DataTable property in Vehicle_Bal i.e, class B

##But the problem is occurs when My code is like this in my method. 

Case2:-
3)  public void CreateVehicle()
  {
 
  Vehicle_Bal ObjB = new Vehicle_Bal();

  ObjB .PurchaseDt = Convert.ToDateTime(txtPurchaseDate.Text);
  ObjB .WarrentyDt = Convert.ToDateTime(txtWarrentyDate.Text);
  ObjB .MIsc = txtMisc.Text;
  ObjB .VStatus = ddlVStatus.SelectedItem.Text;
 
  (*)ObjB .DtTyre = TYPE_TYRE();-----------(1)
 
4)----ObjB .BlCreateVeh();
  }
 
5) )  protected void btnsave_Click(object sender, EventArgs e)
  {
      CreateVehicle()
  }

In case2 to Upto (*) its is working good, when Im calling  (4) i.e method from Class B and Passing the DataTable to Class B I'm not getting any Data
