DockPanel Suite DockContent全部出现在DockPanel的左上方

Question

有时，当我的程序启动时，无法将DockPanel DockContent放置在配置文件中分配的正确位置。

配置文件如下所示：

<?xml version="1.0" encoding="utf-16"?>
<!--DockPanel configuration file. Author: Weifen Luo, all rights reserved.-->
<!--!!! AUTOMATICALLY GENERATED FILE. DO NOT MODIFY !!!-->
<DockPanel FormatVersion="1.0" DockLeftPortion="0.25" DockRightPortion="0.25" DockTopPortion="0.25" DockBottomPortion="0.25" ActiveDocumentPane="-1" ActivePane="-1">

      <NestedPanes Count="0" />
    </DockWindow>
    <DockWindow ID="3" DockState="DockTop" ZOrderIndex="4">
      <NestedPanes Count="0" />
    </DockWindow>
    <DockWindow ID="4" DockState="DockBottom" ZOrderIndex="0">
      <NestedPanes Count="2">
        <Pane ID="0" RefID="0" PrevPane="-1" Alignment="Right" Proportion="0.5" />
        <Pane ID="1" RefID="1" PrevPane="0" Alignment="Right" Proportion="0.215625" />
      </NestedPanes>
    </DockWindow>
  </DockWindows>
  <FloatWindows Count="0" />
</DockPanel>

在我的代码中，我具有这三个DockPanel方法，这些方法获取ContentFromPersistString，保存并加载配置文件。

private readonly DeserializeDockContent _deserializeDockContent; 

private IDockContent GetContentFromPersistString(string persistString)
        {
            MainLog("GetContentFromPersistString " + persistString);
            if (persistString == typeof(FrmLogging).ToString())
            {
                logToolStripMenuItem.Checked = true;
                _frmLogging.Dock = DockStyle.Fill;
                return _frmLogging;
            }
            else if (persistString == typeof(FrmTimers).ToString())
            {
                timersToolStripMenuItem.Checked = true;
                _frmTimers.Dock = DockStyle.Fill;
                return _frmTimers;
            }
            else if (persistString == typeof(FrmImageAssessmentControl).ToString())
            {
                imageAssessmentToolStripMenuItem.Checked = true;
                _frmIac.Dock = DockStyle.Fill;
                return _frmIac;
            }
            else if (persistString == typeof(FrmRestrictedBrowser).ToString())
            {
                restrictedBrowserToolStripMenuItem.Checked = true;
                _frmRb.Dock = DockStyle.Fill;
                return _frmRb;
            }
            else if (persistString == typeof(FrmGroupCandidates).ToString())
            {
                groupCandidatesToolStripMenuItem.Checked = true;
                _frmGc.Dock = DockStyle.Fill;
                return _frmGc;
            }
            else
            {
                MainLog("Received Window PersistString: " + persistString);
                return null;
            }
        }

        private void LoadDockingWindowsConfiguration()
        {
            MainLog("LoadDockingWindowsConfiguration()");
            // ReSharper disable once AssignNullToNotNullAttribute
            string configFile = Path.Combine(Path.GetDirectoryName(Application.ExecutablePath), "DockPanel.config");

            try
            {
                if (File.Exists(configFile))
                    dockPanel1.LoadFromXml(configFile, _deserializeDockContent);
            }
            catch (Exception ex)
            {
                MainLog("Error: LoadDockingWindowsConfiguration " + ex.Message);
            }

        }

        private void SaveDockingWindowConfiguration()
        {
            MainLog("SaveDockingWindowConfiguration()");
            // ReSharper disable once AssignNullToNotNullAttribute
            string configFile = Path.Combine(Path.GetDirectoryName(Application.ExecutablePath), "DockPanel.config");
            if (_saveLayout)
                dockPanel1.SaveAsXml(configFile);
            else if (File.Exists(configFile))
                File.Delete(configFile);
        }

在MainForm初始化程序中，我有这个：

 _deserializeDockContent = GetContentFromPersistString;  

我们在表单加载事件中加载对接配置，如下所示：

 LoadDockingWindowsConfiguration();  

这确实是一件令人讨厌的事，将DockContent放置在正确位置的任何帮助将不胜感激。
