请问WPF Spread中能不能像以前版本那样将一列类型设置成按钮

谢谢，表头的文字能不能竖着显示？
这个我自己想办法解决了，把这列设置成自动折行，然后在列头文字中添加\r\n换行，好在我这些列的下面都是CheckBox，如果不是的话这个方法就不能实现了，不然下面表中的文字也换行了。。。 你可以设置文字是否要换行。如果把WordWrap 设置成false， 就不会换行了。
问题解决了就好。:jy74a: 回复 4楼Zoe的帖子
哈哈， 我发现我的问题好多，现在有个 回车跳格的问题，
以前的是这样写的，现在的就不会了。。
InputMap im;
im = ospd.GetInputMap(FarPoint.Win.Spread.InputMapMode.WhenAncestorOfFocused);
im.Put(new FarPoint.Win.Spread.Keystroke(Keys.Enter, Keys.None), FarPoint.Win.Spread.SpreadActions.MoveToNextColumnWrap);
im = ospd.GetInputMap(FarPoint.Win.Spread.InputMapMode.WhenFocused);
im.Put(new FarPoint.Win.Spread.Keystroke(Keys.Enter, Keys.None), FarPoint.Win.Spread.SpreadActions.MoveToNextColumnWrap);
this.gcSpreadSheet1.View.KeyMap.Remove(new KeyStroke(Key.Enter, ModifierKeys.None));
this.gcSpreadSheet1.View.KeyMap.Add(new KeyStroke(Key.Enter, ModifierKeys.None), SpreadActions.NavigationNext);

您好，又麻烦您了， 这种方式的实现可不可以写成 spd.ActiveSheet.Columns.XX=new Text();这种形式，因为有些列我还要用原有的类型， 不这样的话很可能整个表都需要重新来定义。。 产品目前不支持这个功能，可能需要重新定义了。在后续版本的开发中，我们会考虑添加这个功能。 回复 8楼Zoe的帖子
谢谢，希望推出新的版本
现在有个问题 如果我New一个Control类型就可以绑定到该列
但是如果我用穿过来的Control 却只能绑定在这一列的最后，请问这是什么原因？
这是New的正常
Button btnDelete = new Button() { Content = "Delete" };
这是我传过来的 Control 只有最后一行能绑定上
Button btnDelete = listControl.MyControlType as Button;
--------------------------------------------------------------------------------------
下面正常
dobj = new ControlDrawingObject(row, column, btnDelete);
return new DrawingObject[] { dobj };

追加询问：
现有的列类型 如何限制长度以及录入的类型？ 抱歉，您说的这个问题，能否提供简单的demo 方便我们找出问题。
