Hover Hover event does not fire on panel in C #

Question

I am trying to write code in the Mouse_Hover event of a panel in my winform application using C #. This is my code.

private void viewscreen_MouseHover(object sender, EventArgs e) { statuspnl.Enabled = true; statuspnl.Visible = true; } 

but the problem is that the event does not fire when I click on the viewbar.

  // viewscreen // this.viewscreen.BackColor = System.Drawing.SystemColors.ActiveCaptionText; this.viewscreen.Controls.Add(this.statuspnl); this.viewscreen.Location = new System.Drawing.Point(208, 16); this.viewscreen.Name = "viewscreen"; this.viewscreen.Size = new System.Drawing.Size(370, 290); this.viewscreen.TabIndex = 0; this.viewscreen.MouseHover += new System.EventHandler(this.viewscreen_MouseHover);

Create a single application window named "panelvisible". Add one form as "Form1" and add this code to the appropriate files.

Code for the designer

 namespace panelvisible { partial class Form1 { /// <summary> /// Required designer variable. /// </summary> private System.ComponentModel.IContainer components = null; /// <summary> /// Clean up any resources being used. /// </summary> /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param> protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } #region Windows Form Designer generated code /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { this.panel1 = new System.Windows.Forms.Panel(); this.label1 = new System.Windows.Forms.Label(); this.panel2 = new System.Windows.Forms.Panel(); this.panel1.SuspendLayout(); this.SuspendLayout(); // // panel1 // this.panel1.BackColor = System.Drawing.Color.Red; this.panel1.Controls.Add(this.panel2); this.panel1.Controls.Add(this.label1); this.panel1.Location = new System.Drawing.Point(101, 36); this.panel1.Name = "panel1"; this.panel1.Size = new System.Drawing.Size(200, 100); this.panel1.TabIndex = 0; this.panel1.MouseHover += new System.EventHandler(this.panel1_MouseHover); // // label1 // this.label1.AutoSize = true; this.label1.Location = new System.Drawing.Point(49, 42); this.label1.Name = "label1"; this.label1.Size = new System.Drawing.Size(31, 13); this.label1.TabIndex = 0; this.label1.Text = "Hello"; this.label1.Visible = false; // // panel2 // this.panel2.BackColor = System.Drawing.Color.Gray; this.panel2.Location = new System.Drawing.Point(33, 70); this.panel2.Name = "panel2"; this.panel2.Size = new System.Drawing.Size(118, 10); this.panel2.TabIndex = 1; this.panel2.Visible = false; // // Form1 // this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; this.ClientSize = new System.Drawing.Size(494, 205); this.Controls.Add(this.panel1); this.Name = "Form1"; this.Text = "Form1"; this.panel1.ResumeLayout(false); this.panel1.PerformLayout(); this.ResumeLayout(false); } #endregion private System.Windows.Forms.Panel panel1; private System.Windows.Forms.Label label1; private System.Windows.Forms.Panel panel2; } } 

Code for code

 using System; using System.Windows.Forms; namespace panelvisible { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void panel1_MouseHover(object sender, EventArgs e) { this.label1.Visible = true; this.label1.Enabled = true; this.panel2.Visible = true; this.panel2.Enabled = true; } } }

Do you have this code?

 this.viewscreen.MouseHover += new System.EventHandler(this.viewscreen_MouseHover); 

It should be added automatically, but make sure you don't change this ... Another way is to remove the mouseover event and add it again.

Hope this helps.

Are you viewing a form screen or is it really a panel? And is the panel / form enabled?
