Xceed.Wpf.DataGrid Assembly > Xceed.Wpf.DataGrid.Views Namespace : TableViewScrollViewer Class

Represents a scrollable area that can contain other visible elements laid out in a tableview.

Syntax

Visual Basic (Declaration) 
<TemplatePartAttribute(Name="PART_RowSelectorPane", Type=Xceed.Wpf.DataGrid.RowSelectorPane)>
Public Class TableViewScrollViewer 
   Inherits DataGridScrollViewer
   Implements ISupportInitialize, IFrameworkInputElement, IInputElement, IAddChild, IHaveResources, IAnimatable, DUCE.IResource 
C# 
[TemplatePartAttribute(Name="PART_RowSelectorPane", Type=Xceed.Wpf.DataGrid.RowSelectorPane)]
public class TableViewScrollViewer : DataGridScrollViewer, ISupportInitialize, IFrameworkInputElement, IInputElement, IAddChild, IHaveResources, IAnimatable, DUCE.IResource 

Example

All examples in this topic assume that the grid is bound to the Orders table of the Northwind database, unless stated otherwise.
The following example demonstrates how to prevent scroll bars from being displayed by providing an implicit style for the TableViewScrollViewer that sets the HorizontalScollBarVisibility and VerticalScrollBarVisibility properties to Hidden.
XAMLCopy Code
<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid"> 
  <Grid.Resources> 
    <xcdg:DataGridCollectionViewSource x:Key="cvs_persons" 
                                    Source="{Binding Source={x:Static Application.Current},  
                                                     Path=Persons}"/> 
 
    <Style TargetType="{x:Type xcdg:TableViewScrollViewer}"> 
      <Setter Property="HorizontalScrollBarVisibility" 
              Value="Hidden"/> 
 
      <Setter Property="VerticalScrollBarVisibility" 
              Value="Hidden"/> 
    </Style> 
  </Grid.Resources> 
  <xcdg:DataGridControl x:Name="PersonGrid" 
                        ItemsSource="{Binding Source={StaticResource cvs_persons}}"/> 
</Grid>

Remarks

Fixed Columns vs. Templates This feature is available only in the Professional Edition 

In order to support fixed columns when creating a new row template for a table-view layout, the following criteria must be met:

  1. The PART_CellsHost template part must be a FixedCellPanel.
  2. The FixedCellCount property of the FixedCellPanel must be bound to the table view's FixedColumnCount property using a TwoWay ViewBinding.

The fixed-cell-panel properties listed below are also usually bound when provided a new row template for a table-view layout:

  1. SplitterStyle (TemplateBinding xcdg:TableView.FixedColumnSplitterStyle)
  2. SplitterWidth (xcdg:ViewBinding FixedColumnSplitterWidth)
  3. ShowSplitter (xcdg:ViewBinding ShowFixedColumnSplitter)
  4. FixedColumnDropMarkPen (xcdg:ViewBinding FixedColumnDropMarkPen)

If a new template is provided for a DataGridControl and fixed columns are to be supported, it is essential that a TableViewScrollViewer be used. This scroll viewer is responsible for preserving the TranslateTransforms that fix and scroll elements, as well as executing the PageLeft and PageRight actions according to the reduced viewport.  It is also recommended that an AdornerDecorator be located above the TableViewScrollViewer of the templated DataGridControl to support drag and dropping of the fixed-column splitter correctly.
