[英]C# Property Grid
I am writing an application which is going to allows users to change the properties of a text box or label and these controls are user controls. 我正在编写一个应用程序,它将允许用户更改文本框或标签的属性,并且这些控件是用户控件。 Would it be easiest to create a separate class for each user control which implements the properties I want them to be able to change and then bind those back to the user control?
为每个用户控件创建一个单独的类,实现实现我希望它们能够更改的属性,然后将其绑定回用户控件,是否最简单? Or is there another method I am overlooking?
还是我还有其他方法要忽略?
Create a custom Attribute, and tag the properties you want the user to edit with this attribute. 创建一个自定义属性,并使用该属性标记要用户编辑的属性。 Then set the BrowsableAttribute property on the property grid to a collection containing only your custom attribute:
然后将属性网格上的BrowsableAttribute属性设置为仅包含您的自定义属性的集合:
public class MyForm : Form
{
private PropertyGrid _grid = new PropertyGrid();
public MyForm()
{
this._grid.BrowsableAttributes = new AttributeCollection(new UserEditableAttribute());
this._grid.SelectedObject = new MyControl();
}
}
public class UserEditableAttribute : Attribute
{
}
public class MyControl : UserControl
{
private Label _label = new Label();
private TextBox _textBox = new TextBox();
[UserEditable]
public string Label
{
get
{
return this._label.Text;
}
set
{
this._label.Text = value;
}
}
[UserEditable]
public string Value
{
get
{
return this._textBox.Text;
}
set
{
this._textBox.Text = value;
}
}
}
