我怎样才能得到一个PropertyGrid中显示SaveFileDialog？

问题描述

我有，我希望能够以显示SaveFileDialog为用户在数据导出到一个新文件的过程属性网格控制。我可以很容易地挂钩一个OpenFileDialog与FileNameEditor但似乎没有要保存文件的等价类。

I have a property grid control where I want to be able to display a SaveFileDialog as the user is in the process of exporting data to a new file. I can easily hook up an OpenFileDialog with a FileNameEditor but there doesn't seem to be an equivalent class for saving files.

有没有办法，我可以指定一个现有的类在System.ComponentModel.Editor属性，这样一个SaveFileDialog显示？

Is there an existing class that I can specify in the System.ComponentModel.Editor attribute so that a SaveFileDialog is displayed?

推荐答案

所以您在设置的对象 propertyGrid1.SelectedObject 需要的公共属性如下所示：

So the object that you set in the propertyGrid1.SelectedObject needs a public property like the following:

            private string _saveFile;
	[BrowsableAttribute(true)]
	[EditorAttribute(typeof(SaveFileNameEditor), typeof(System.Drawing.Design.UITypeEditor))]
	public string SaveFileEditorVlad
	{
		get { return _saveFile; }
		set { _saveFile = value; }
	}

为了使的的回答工作:)然后在运行时，当您编辑此属性，省略号会显示，你就可以选择一个文件另存为。

in order to make Stewy's answer work :) Then at runtime, when you edit the this property, the ellipsis will show and you'll be able to select a file to Save As.
