不能以可视方式更改的DataGridView在继承的形式 [英] Cannot visually change DataGridView in inherited form

问题描述

我有一个WinForms与 DataGridView的上形成。在 DataGridView的设置为保护。

当我继承的形式，这是不可能更改 DataGridView的在Visual Studio设计。如果我做一个按钮，它按预期工作的整个事情。

有没有办法解决这个问题？

有些（剪切）码（从DatagridForm.Designer.cs）：

 部分类DatagridForm {
保护的DataGridView DGDATA; 
保护Button按钮; 
} 
  

和来自Inherited.cs：

 部分类继承：DatagridForm {
 
} 
  

解决方案

这博客有解决方案：只要创建一个指向正确的设计师的东西继承的用户控件：

  [设计师（ typeof运算（System.Windows.Forms.Design.ControlDesigner））] 
公共类ucInheritedDataGridView：DataGridView的{} 
  

工程就像一个魅力。唯一的缺点是你不能使用.NET客户端配置文件，因为它有System.Forms.Design不支持（必须添加 System.Design 作为参考）。这不应该是太大的问题，因为客户端配置文件是过时反正每4.5

如果你真的需要在客户端配置文件，另一个解决办法是在<$ C包住 DataGridView的 $ C>面板，您可以移动和调整。

I have a WinForms form with a DataGridView on it. The DataGridView is set to protected.

When I inherit that form, it is not possible to change the DataGridView in the Visual Studio designer. If I do the whole thing with a Button, it works as expected.

Is there a way to fix this?

Some (clipped) code (from DatagridForm.Designer.cs):

partial class DatagridForm {
    protected DataGridView dgData;
    protected Button button;
}

and from Inherited.cs:

partial class Inherited : DatagridForm {

}

解决方案

This blog has the solution: just create an inherited user control that points to the right designer stuff:

[Designer(typeof(System.Windows.Forms.Design.ControlDesigner))]
public class ucInheritedDataGridView : DataGridView { }

Works like a charm. Only downside is that you cannot use the .NET Client Profile, because it has no support for System.Forms.Design (you have to add System.Design as a reference). This shouldn't be too much of a problem, because the client profile is deprecated anyway per 4.5.

If you really need the client profile, another work around is to wrap the DataGridView in a Panel, which you can move and resize.
