.NET Framework Class Library GridTableStylesCollection Class Namespace:
System.Windows.FormsAssembly:
System.Windows.Forms (in System.Windows.Forms.dll)
 Syntax
Visual Basic (Declaration) <ListBindableAttribute(False)> _
Public Class GridTableStylesCollection _
Inherits BaseCollection _
Implements IList, ICollection, IEnumerable
Dim instance As GridTableStylesCollection
[ListBindableAttribute(false)]
public class GridTableStylesCollection : BaseCollection, IList,

public class GridTableStylesCollection extends BaseCollection implements IList, ICollection, IEnumerable
Remarks
The GridTableStylesCollection contains DataGridTableStyle objects that allows the DataGrid control to display a customized grid style for each DataTable in a DataSet. On the DataGrid control, the TableStyles property returns the GridTableStylesCollection. By default, the GridTableStylesCollection does not contain any DataGridTableStyle objects.Instead, the DataGrid displays each table using default settings for color, width, and formatting.All columns of each table are displayed.When a DataGridTableStyle is added to the collection, the DataGrid uses the MappingName to determine which object supplies the data for the grid.For example, if the data source is a DataSet that contains three DataTable objects, the MappingName must match the TableName of one of the objects.If the MappingName does not match any of the TableName values, the default settings will be used to display data for each table, and the DataGridTableStyle settings will be ignored.

The following code example creates two DataGridTableStyle objects and adds each to the GridTableStylesCollection returned by the TableStyles property of a DataGrid control. AddCustomDataTableStyle()
