我在 WPF(c#) 中编写了一个程序。我使用 DataSet 来填充 DataGrid。DataGrid 单元格在向上/向下滚动后更新并更改其位置和大小！我怎么解决这个问题？我想 DataGrid 在滚动之前自行更新。
这是示例：
滚动前：
滚动后：
这是我的 XAML 代码：
<Window x:Class="RFID.CareerWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<Setter Property="FlowDirection" Value="RightToLeft"></Setter>
</Style>
<Style x:Key="DataGridCellStyle" TargetType="DataGridCell">
<Setter Property="HorizontalAlignment" Value="Center" />
</Style>
</Grid.Resources>
<GroupBox Header="نوع عملیات" Margin="10,200,10,0" VerticalAlignment="Top" Height="110" Style="{StaticResource GroupBoxStyle}">

<GroupBox Header="" Margin="10,433,10,0" VerticalAlignment="Top" Height="105" Style="{StaticResource GroupBoxStyle}">

c</Canvas>
</GroupBox>
<DataGrid x:Name="dg1" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Height="185" Width="408" FlowDirection="RightToLeft" FontFamily="2 badr" FontSize="20" VerticalContentAlignment="Center" HorizontalContentAlignment="Center" AlternatingRowBackground="DarkGoldenrod">
</DataGrid>
</Grid>
</Viewbox>
</Window>
这是 C# 代码：
namespace RFID
{
/// <summary>
/// Interaction logic for CareerWindow.xaml
/// </summary>
public partial class CareerWindow : Window
{
public CareerWindow()
{
InitializeComponent();
loadAll();
}
private void loadAll()
{
DBConnect con = new DBConnect();
dg1.ItemsSource = con.getTopCustomerInScore(0).Tables[0].DefaultView;
}
}
}
