我试图使用 PanelName添加文本视图。 Controls.Add（ LabelName）它在一个案例中有效，但在其他情况下无效。

案例1：我创建了一个TabControl和一个标签页，然后动态添加了另一个带有面板且包含标签的标签页。

案例2 ：当我使用给定代码动态添加一个面板（已经创建）主tabcontrol时，它无法正常工作。

public Form0（） { 的InitializeComponent（）; //////// 案例2 //顶部面板 Panel panelTop = new Panel（）; panelTop.Dock = DockStyle.Top; panelTop.BackColor = Color.Yellow; tabPage1.Controls.Add（panelTop）; //标题 标签头=新标签（）; Head.Name =" LAMDA"; Head.AutoSize = true; //Head.Anchor = AnchorStyles.Top& AnchorStyles.Right& AnchorStyles.Left; // Head.ForeColor = Color.Black; // Head.Size = new Size（20,10）; // Head.Location = new Point（20,20）; panelTop.Controls.Add（Head）; Head.Parent = panelTop; // bottom // left //右边 //填写¥b $ b InitializeProfile（）; }¥b $ b void InitializeProfile（） { $ createTabProfile（）; $ }¥b $ b void createTabProfile（） ///////// CASE 1 { //个人简介attribs TabPage tab1 = new TabPage（" Profile"）; tab1.BackgroundImage = Image.FromFile（" .\\BackTab.png"）; tab1.BackgroundImageLayout = ImageLayout.Center; tab1.BackColor = Color.White; tabControl1.TabPages.Add（tab1）; $ $ //面板创建主体$ Panel mainPanel = new Panel（）; mainPanel.Dock = DockStyle.Fill; mainPanel.BackColor = DefaultBackColor; tab1.Controls.Add（mainPanel）; //名称标签问候语部分¥b $ b 标签NameLabel =新标签（）; NameLabel.Text =" NAME"; $ NameLabel.Location = new Point（210,0）; mainPanel.Controls.Add（NameLabel）; // DP PictureBox DP =新PictureBox（）; DP.Image = Image.FromFile（@" .\\NarutoDP.png"）; DP.Size =新尺寸（150,150）; DP.Name =" DP"; DP.BorderStyle = BorderStyle.FixedSingle; DP.Location =新点（0,0）; DP.Visible = true; mainPanel.Controls.Add（DP）; DP.Parent = mainPanel; // tab1.Controls.Add（DP）; $ }

解决方案

如果将代码从表单构造函数移动到Load或Shown事件，它是否有效？

I was trying to add a text view using PanelName.Controls.Add(LabelName) it worked in one case but doesnt working other.

Case 1: I created a TabControl and a tabpage then dynamically added another tabpage having a panel and containing label worked.

Case 2: When I added a panel dynamically to (already created) main tabcontrol using given code it doen not worked.

public Form0() { InitializeComponent(); ////////CASE 2 //Top panel Panel panelTop = new Panel(); panelTop.Dock = DockStyle.Top; panelTop.BackColor = Color.Yellow; tabPage1.Controls.Add(panelTop); //HEading Label Head = new Label(); Head.Name = "LAMDA"; Head.AutoSize = true; //Head.Anchor = AnchorStyles.Top & AnchorStyles.Right & AnchorStyles.Left; // Head.ForeColor = Color.Black; // Head.Size = new Size(20, 10); // Head.Location = new Point(20,20); panelTop.Controls.Add(Head); Head.Parent = panelTop; //bottom //left // right //fill InitializeProfile(); } void InitializeProfile() { createTabProfile(); } void createTabProfile() /////////CASE 1 { //Profile attribs TabPage tab1 = new TabPage("Profile"); tab1.BackgroundImage = Image.FromFile(".\\BackTab.png"); tab1.BackgroundImageLayout = ImageLayout.Center; tab1.BackColor = Color.White; tabControl1.TabPages.Add(tab1); //Panel creating main Panel mainPanel = new Panel(); mainPanel.Dock = DockStyle.Fill; mainPanel.BackColor = DefaultBackColor; tab1.Controls.Add(mainPanel); //Name Label Greeting part Label NameLabel = new Label(); NameLabel.Text = "NAME"; NameLabel.Location = new Point(210,0); mainPanel.Controls.Add(NameLabel); //DP PictureBox DP = new PictureBox(); DP.Image = Image.FromFile(@".\\NarutoDP.png"); DP.Size = new Size(150, 150); DP.Name = "DP"; DP.BorderStyle = BorderStyle.FixedSingle; DP.Location = new Point(0, 0); DP.Visible = true; mainPanel.Controls.Add(DP); DP.Parent = mainPanel; // tab1.Controls.Add(DP); }

解决方案

If you move the code from the form constructor to either Load or Shown event does it work?
