private void AddCustomDataTableStyle()
{
   myDataGridTableStyle1 = new DataGridTableStyle();
   myDataGridTableStyle1.MappingNameChanged+=
      new System.EventHandler(MappingNameChanged_Handler);
   myDataGridTableStyle1.GridLineStyleChanged += 
      new System.EventHandler(GridLineStyleChanged_Handler);
   myDataGridTableStyle1.MappingName = "Customers";

   // Set other properties.
   myDataGridTableStyle1.AlternatingBackColor = Color.LightGray;
   myDataGridTableStyle1.GridLineStyle=
      System.Windows.Forms.DataGridLineStyle.None;

   // Add a GridColumnStyle and set its MappingName.          
   DataGridColumnStyle myBoolCol = new DataGridBoolColumn();
   myBoolCol.MappingName = "Current";
   myBoolCol.HeaderText = "IsCurrent Customer";
   myBoolCol.Width = 150;
   myDataGridTableStyle1.GridColumnStyles.Add(myBoolCol);

   // Add a second column style.
   DataGridColumnStyle myTextCol = new DataGridTextBoxColumn();
   myTextCol.MappingName = "custName";
   myTextCol.HeaderText = "Customer Name";
   myTextCol.Width = 250;
   myDataGridTableStyle1.GridColumnStyles.Add(myTextCol);

   // Create new ColumnStyle objects.
   DataGridColumnStyle cOrderDate = new DataGridTextBoxColumn();
   cOrderDate.MappingName = "OrderDate";
   cOrderDate.HeaderText = "Order Date";
   cOrderDate.Width = 100;

   // Use PropertyDescriptor to create a formatted column.         
   PropertyDescriptorCollection myPropertyDescriptorCollection = this.BindingContext
      [myDataSet, "Customers.custToOrders"].GetItemProperties();

   csOrderAmount.MappingName = "OrderAmount";
   csOrderAmount.HeaderText = "Total";
   csOrderAmount.Width = 100;

   // Add the DataGridTableStyle object to GridTableStylesCollection.
   myDataGrid.TableStyles.Add(myDataGridTableStyle1);
