For more information about handling events, see Handling and Raising Events.

The following code example allows you to toggle sorting availability on a DataGrid by clicking a button and the current sorting status is displayed in a label. This example requires that you have a DataGrid with a System.Data.DataSet that contains some data, a Button and a Label on a Form.

private void DataGridTableStyle_Sample_Load(object sender,
                                       EventArgs e)
{
   myDataGridTableStyle1 = new DataGridTableStyle();

   mylabel.Text = "Sorting Status :" + 
         myDataGridTableStyle1.AllowSorting.ToString();
   if(myDataGridTableStyle1.AllowSorting == true)
   {
      btnApplyStyles.Text = "Remove Sorting";
   }
   else
   {
      btnApplyStyles.Text = "Apply Sorting";
   }
   // Attach custom event handlers.
   myDataGridTableStyle1.AllowSortingChanged += 
               new System.EventHandler(AllowSortingChanged_Handler);
   myDataGridTableStyle1.MappingName = "Customers";
} 
private void AllowSortingChanged_Handler(object sender,EventArgs e)
{         
   mylabel.Text = "Sorting Status :" 
         + myDataGridTableStyle1.AllowSorting.ToString();
}     
private void btnApplyStyles_Click(object sender, EventArgs e)
{       

   if(myDataGridTableStyle1.AllowSorting == true)
   {            
      // Remove sorting.
      myDataGridTableStyle1.AllowSorting = false; 
      btnApplyStyles.Text = "Allow Sorting";
   }
   else
   {
      // Allow sorting.
      myDataGridTableStyle1.AllowSorting = true;
      btnApplyStyles.Text = "Remove Sorting";
   } 

   mylabel.Text = "Sorting Status :" + myDataGridTableStyle1.AllowSorting;
   // Add the DataGridTableStyle to DataGrid.
   myDataGrid.TableStyles.Add(myDataGridTableStyle1);
}
