Question

我有一个gridcontrol（GridControl1）在gridcontrol里面，有两个网格视图（GridView1＆amp; GridView2）我想获得GridView2中Selected行项的值并将其放在文本框中。在GridView1上我可以使用此代码获取：

public static Size GetCurrentDisplaySize() {
    var displayInformation = DisplayInformation.GetForCurrentView();
    TypeInfo t = typeof(DisplayInformation).GetTypeInfo();
    var props = t.DeclaredProperties.Where(x => x.Name.StartsWith("Screen") && x.Name.EndsWith("InRawPixels")).ToArray();
    var w = props.Where(x => x.Name.Contains("Width")).First().GetValue(displayInformation);
    var h = props.Where(x => x.Name.Contains("Height")).First().GetValue(displayInformation);
    var size = new Size(System.Convert.ToDouble(w), System.Convert.ToDouble(h));
    switch (displayInformation.CurrentOrientation) {
    case DisplayOrientations.Landscape:
    case DisplayOrientations.LandscapeFlipped:
        size = new Size(Math.Max(size.Width, size.Height), Math.Min(size.Width, size.Height));
        break;
    case DisplayOrientations.Portrait:
    case DisplayOrientations.PortraitFlipped:
        size = new Size(Math.Min(size.Width, size.Height), Math.Max(size.Width, size.Height));
        break;
    }
    return size;
}

但如果我在GridView2上选择任何一行，我什么也得不到。

有没有办法做到这一点。

如果您使用了主要细节，请查看help article describing in detail

在你的GridControl中你必须处理Grid_MasterRowExpanded，然后在程序上添加gridView.SelectionChanged的句柄，这段代码会帮助你

 Private Sub Grid_MasterRowExpanded(ByVal sender As System.Object, ByVal e As DevExpress.XtraGrid.Views.Grid.CustomMasterRowEventArgs) Handles Grid.MasterRowExpanded
        Dim view As GridView = sender
        Dim detail As GridView = view.GetDetailView(e.RowHandle, e.RelationIndex)
        detail.OptionsSelection.MultiSelect = True

        If e.RowHandle = 0 Or e.RowHandle = 1 Then
            AddHandler detail.SelectionChanged, AddressOf detail_SelectionChanged
        End If

    End Sub

    Private Sub detail_SelectionChanged(ByVal sender As System.Object, ByVal e As DevExpress.Data.SelectionChangedEventArgs)

        viewSelected = sender

        Dim ro As DataRowView = viewSelected.GetFocusedRow
       txtEmpId.Text = ro.Item("colEmp_Id") 

    End Sub

从gridview2获取选定的行项目
