问题描述
我有一个属性网格,并且其中一个属性使用 UITypeEditor 来编辑值(在表单上).
I have a property grid and one of the properties uses a UITypeEditor to edit the value (on a form).
但是该属性仍然是可编辑的,我不希望如此.有没有办法做到这一点?我查看了类似的问题 Propertygrid UIEditor禁用了通过键盘进行值编辑,但是它不能解决我的问题,因为解决方案是使用TypeConverter的简单下拉列表.
However the property is still editable, which I do not want. Is there a way to do this? I looked at this similar question Propertygrid UIEditor disabling value editing through Keyboard but it does not solve my problem as the solution is a simple dropdown list using TypeConverter.
推荐答案
一种解决方案是声明 TypeConverter 不会执行任何操作,诸如此类:
One solution is to declare a TypeConverter that does ... nothing, something like this:
这是您要编辑的课程:
public class MyClass
{
[Editor(typeof(MyClassEditor), typeof(UITypeEditor))]
[TypeConverter(typeof(MyConverter))]
public string MyProperty { get; set; }
}
这是自定义UITypeEditor:
This is the custom UITypeEditor:
public class MyClassEditor : UITypeEditor
{
public override UITypeEditorEditStyle GetEditStyle(ITypeDescriptorContext context)
{
return UITypeEditorEditStyle.Modal;
}
public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value)
{
MessageBox.Show("press ok to continue");
return "You can't edit this";
}
}
这是著名的转换器,我花了几天的时间来写:
This is the famous converter that took me days to write:
// this class does nothing on purpose
public class MyConverter : TypeConverter
{
}
