如何在PropertyValueChanged事件中获取PropertyGrid标签和GridItem标签 [英] How to get PropertyGrid tag and GridItem tag in PropertyValueChanged event

问题描述

我写了一个窗口申请表.表单上有一个buuton，单击它时，popram将创建一个新的PropertyGrid，并为其设置一些功能，如下所示:

I write a window application form. There is one buuton on the form, when click it, the popram will create a new PropertyGrid, and set some features for it as below :

PropertyGrid NewPropertyGrid = new PropertyGrid();
NewPropertyGrid.tag = CheckString;
NewPropertyGrid.PropertyValueChanged += new PropertyValueChangedEventHander(NewPropertyGrid_PropertyValueChanged);
NewPropertyGrid.SelectedObject = NewObject;

当用户更改PropertyGrid的GridItem中的值时，将调用以下事件.

When user changes the value in the PropertyGrid''s GridItem, the event below will be invoked.

void NewPropertyGrid_PropertyValueChanged(object s, PropertyValueChangedEventArgs e)

现在的问题如下:

如何获取PropertyGrid的对象，以便获取其标记(例如PropertyGrid.tag)并在此事件中做进一步检查?

The question now is below :

How can I get the object of the PropertyGrid, so that I can get its tag (eg PropertyGrid.tag) and do further check in this event ?

推荐答案

void NewPropertyGrid_PropertyValueChanged(object s, PropertyValueChangedEventArgs e)

在这里，"s"将为您提供PropertyGrid作为对象.您需要投射并使用它

更新1 :
您还可以检查 e.OriginalSource .


更新2 :
你应该像这样，

Here "s" will give you the PropertyGrid as object. You need to cast it and use it

Update 1:
You can also check e.OriginalSource.


Update 2:
You are supposed to cast like,

((PropertytyGrid)s).Tag

或

or

(s as PropertyGrid).Tag

将其标记为有帮助的答案

Mark it as answer if it helps you
