如何在（锚定或停靠）之后获得控制高度？ [英] How to get height of control after (anchored or docked )?

问题描述

我正在为项目创建自定义datagridview控件。我必须计算要添加的行数以避免垂直滚动条。当用户控件未锚定或停靠时它可以工作但是当（锚定或停靠）然后它失败时。



当我检查计算时，控制大小给出控制前的控件大小或锚点发生。

如何在停靠或锚定后获得实际的运行时控制大小？

推荐答案

简单：处理Resize事件。

Simple: handle the Resize event.

public partial class MyUserControl : UserControl
    {
    public MyUserControl()
        {
        InitializeComponent();
        ShowSize("Constructor");
        }
    private void ShowSize(string from)
        {
        Debug.WriteLine("{0} : ({1}, {2})", from, Width, Height);
        }
    private void MyUserControl_Load(object sender, EventArgs e)
        {
        ShowSize("Load");
        }
    private void MyUserControl_Resize(object sender, EventArgs e)
        {
        ShowSize("Resize");
        }
    }

添加到表单，并设置为Dock：填写设计器。

运行应用程序，然后你get：

Add to a form, and set as Dock:Fill in the designer.
Run the app, and you get:

Constructor : (150, 150)
Resize : (357, 188)
Load : (357, 188)
Resize : (531, 381)

表单原始大小为：（373,226）并且表单在Form Load事件中调整大小（547,419）

Where the Form original size was: (373, 226) and the form was resized in the Form Load event to (547, 419)
