VB.NET WPF DataGrid光标滚动到指定行

本篇介绍VB.NET在WPF中怎么滚动光标到指定的行

1.假设你已经在Xaml中配置好DataGrid控件,假如名称为”DGV”

2.写一个通用的方法,用来滚动贯标到指定行

''' <summary>
''' WPF DataGrid定位到指定行
''' </summary>
''' <param name="dataGrid">DataGrid控件</param>
''' <param name="index">指定行的索引</param>
Public Sub ScrollViewVerticalTo(dataGrid As DataGrid, index As Integer)
    Dim lvap As New DataGridAutomationPeer(dataGrid)
    Dim svap As ScrollViewerAutomationPeer = lvap.GetPattern(PatternInterface.Scroll)
    Dim scroll As ScrollViewer = svap.Owner
    scroll.ScrollToVerticalOffset(index)
End Sub

3.调用通用方法

Dispatcher.Invoke(Sub() ScrollViewVerticalTo(DGV, DTable.Rows.IndexOf(rw)))
