how can I enable scrollbars on the WPF Datagrid?
提问by Edward Tanguay
When I run the following Northwind WPF Toolkit Datagridcode from this article, I get a datagrid, but there are no scrollbarsand hence the user can only see part of the datagrid. I am using the newest version March 2009.
当我运行下面的罗斯文WPF工具包Datagrid的从代码这篇文章中，我得到一个数据网格，但有没有滚动条，因此用户只能看到数据网格的一部分。我使用的是 2009 年 3 月的最新版本。
What do I need to specify so that the WPF Datagrid has scrollbars?
我需要指定什么才能使 WPF Datagrid 具有滚动条？
I tried putting the datagrid in a ScrollViewer but that didn't help.
我尝试将数据网格放在 ScrollViewer 中，但这没有帮助。
XAML:
XAML：
<Window x:Class="TestDataGrid566.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:toolkit="http://schemas.microsoft.com/wpf/2008/toolkit"
Title="Window1" Height="600" Width="800">
<StackPanel>
<toolkit:DataGrid x:Name="TheDataGrid" AutoGenerateColumns="True"/>
</StackPanel>
</Window>
code-behind:
代码隐藏：
using System.Linq;
using System.Windows;
using TestDataGrid566.Model;
namespace TestDataGrid566
{
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
NorthwindDataContext db = new NorthwindDataContext();
var customers = from c in db.Customers
select c;
TheDataGrid.ItemsSource = customers;
}
}
}

Put the DataGridin a Grid, DockPanel, ContentControlor directly in the Window. A vertically-oriented StackPanelwill give its children whatever vertical space they ask for - even if that means it is rendered out of view.
把DataGrid在Grid，DockPanel，ContentControl在或者直接Window。垂直方向StackPanel将为其子项提供他们要求的任何垂直空间 - 即使这意味着它被渲染出来。

WPF4
<DataGrid AutoGenerateColumns="True" Grid.Column="0" Grid.Row="0"
ScrollViewer.CanContentScroll="True"
ScrollViewer.VerticalScrollBarVisibility="Auto"
ScrollViewer.HorizontalScrollBarVisibility="Auto">
</DataGrid>
with : <ColumnDefinition Width="350" />& <RowDefinition Height="300" />works fine.
与 : <ColumnDefinition Width="350" />&<RowDefinition Height="300" />工作正常。
Scrollbars don't show with <ColumnDefinition Width="Auto" />& <RowDefinition Height="300" />.
滚动条不显示<ColumnDefinition Width="Auto" />& <RowDefinition Height="300" />。
Also works fine with: <ColumnDefinition Width="*" />& <RowDefinition Height="300" />in the case where this is nested within an outer <Grid>.
也适用于：<ColumnDefinition Width="*" />&<RowDefinition Height="300" />在它嵌套在外部<Grid>.
回答by Jay
If any of the parent containers RowDefinitionHeight set to "Auto"also stoppers for scrollbars
如果任何父容器RowDefinition高度"Auto"也设置为滚动条的塞子
Alternatively you may set Height "*"
或者，您可以设置高度“*”
Which happened in my case.
这在我的情况下发生了。

Add grid with defined height and width for columns and rows. Then add ScrollViewerand inside it add the dataGrid.
为列和行添加具有定义高度和宽度的网格。然后添加ScrollViewer并在其中添加 dataGrid。

In my case I had to set MaxHeightand replace IsEnabled="False"by IsReadOnly="True"
在我而言，我不得不设置MaxHeight和更换IsEnabled="False"由IsReadOnly="True"
