Property Value

Type: System.Boolean

If this property is set to false, links to child tables are not shown.

The following code example toggles the AllowNavigation property between the true and false.


// Create an instance of the 'AllowNavigationChanged' EventHandler.
private void CallAllowNavigationChanged()
{
   myDataGrid.AllowNavigationChanged += 
                                   new EventHandler(Grid_AllowNavChange);
}

// Set the 'AllowNavigation' property on click of a button.
private void myButton_Click(object sender, EventArgs e)
{
   if (myDataGrid.AllowNavigation == true)
      myDataGrid.AllowNavigation = false;
   else
      myDataGrid.AllowNavigation = true;
}

// Raise the event when 'AllowNavigation' property is changed.
private void Grid_AllowNavChange(object sender, EventArgs e)
{
   string myString = "AllowNavigationChanged event raised, Navigation ";
   bool myBool = myDataGrid.AllowNavigation;
   // Create appropriate alert message.
   myString = myString + (myBool ? " is " : " is not ") + "allowed";
   // Show information about navigation.
   MessageBox.Show(myString, "Navigation information");
}
