Cursor="SizeWE"这个双箭头在GridViewColumnHeader和DataGridColumnHeader表示不一样的问题

Question

各位大侠有碰到过Cursor="SizeWE"这个双箭头在GridViewColumnHeader和DataGridColumnHeader样式中表示不一样的问题吗？能改为一致吗？2个代码如下：

<!-- DataGridColumnHeader -->

<Thumb x:Name="PART_RightHeaderGripper"
                               Cursor="SizeWE"
                            HorizontalAlignment="Right"
                            Background="{DynamicResource {ComponentResourceKey localCodes:HedmSkins, WindowButtonPenColor}}"
                               Width="1"
                               Height="15"
                               VerticalAlignment="Center" >
                            <Thumb.BitmapEffect>
                                <DropShadowBitmapEffect Color="#000"
                                                        Direction="-90" ShadowDepth="2" Softness="0.1" Opacity="0.3" />
                            </Thumb.BitmapEffect>
                        </Thumb>

 

<!-- GridViewColumnHeader -->

 <Thumb x:Name="PART_HeaderGripper"
                               Cursor="SizeWE"
                            HorizontalAlignment="Right"
                            Background="{DynamicResource {ComponentResourceKey localCodes:HedmSkins, WindowButtonPenColor}}"
                               Width="1"
                               Height="15"
                               VerticalAlignment="Center" >
                            <Thumb.BitmapEffect>
                                <DropShadowBitmapEffect Color="#000"
                                                        Direction="-90" ShadowDepth="2" Softness="0.1" Opacity="0.3" />
                            </Thumb.BitmapEffect>
                        </Thumb>

GridViewColumnHeader 能改为DataGridColumnHeader 的样式效果

木有人回答啊！

我觉得是不是Thumb x:Name="PART_HeaderGripper"和Thumb x:Name="PART_RightHeaderGripper"导致的问题啊？

找到了，DataGrid用的还是系统定义的，可GridViewColumnHeader用的不是。通过Reflector工具看了下源码：

GridViewColumnHeader 中有个私有属性，

private Cursor SplitCursor
{
  get
  {
    if (_splitCursorCache == null)
    {
      _splitCursorCache = this.GetCursor(100);
    }
    return _splitCursorCache;
  }
}

通过一个静态私有成员来 设置光标：

private static Cursor _splitCursorCache;

这个 this.GetCursor(100) 就返回那个黑色的Resize图标。具体 GetCursor 方法代码如下：

[SecurityCritical, SecurityTreatAsSafe]
private Cursor GetCursor(int cursorID)
{
  Invariant.Assert((cursorID == 100) || (cursorID == 0x65), "incorrect cursor type");
  Cursor cursor = null;
  Stream cursorStream = null;
  Assembly assembly = base.GetType().Assembly;
  if (cursorID == 100)
  {
    cursorStream = assembly.GetManifestResourceStream("split.cur");
  }
  else if (cursorID == 0x65)
  {
    cursorStream = assembly.GetManifestResourceStream("splitopen.cur");
  }
  if (cursorStream != null)
  {
    PermissionSet set = new PermissionSet(null);
    FileIOPermission perm = new FileIOPermission(PermissionState.None) {
      AllLocalFiles = FileIOPermissionAccess.Write
    };
    set.AddPermission(perm);
    set.AddPermission(new EnvironmentPermission(PermissionState.Unrestricted));
    set.AddPermission(new SecurityPermission(SecurityPermissionFlag.UnmanagedCode));
    set.Assert();
    try
    {
      cursor = new Cursor(cursorStream);
    }
    finally
    {
      CodeAccessPermission.RevertAssert();
    }
  }
  return cursor;
}

 

 

他读取了一个内嵌资源。

所以你要使得统一，就只能改GridViewColumnHeader了。所以通过反射把这个类型中的两个静态私有成员的值改掉就好了：

      typeof(GridViewColumnHeader).GetField("_splitOpenCursorCache", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Static).SetValue(null, Cursors.SizeWE);
      typeof(GridViewColumnHeader).GetField("_splitCursorCache", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Static).SetValue(null, Cursors.SizeWE);

这个代码放在你的Window的构造函数里面就可以了。

 

Sincerely,

非常感谢Bob Bao的回答；问题解决了，果然是高手啊；我弄了半天感觉是wpf本身的问题，以为都无解了。非常感谢
