How can I add a hint or tooltip to a label in C# W

Question

It seems that the Label has no Hint or ToolTip or Hovertext property. So what is the preferred method to show a hint, tooltip, or hover text when the Label is approached by the mouse?

Answer 1

Just to share my idea...

I created a custom class to inherit the Label class. I added a private variable assigned as a Tooltip class and a public property, TooltipText. Then, gave it a MouseEnter delegate method. This is an easy way to work with multiple Label controls and not have to worry about assigning your Tooltip control for each Label control.

    public partial class ucLabel : Label
    {
        private ToolTip _tt = new ToolTip();

        public string TooltipText { get; set; }

        public ucLabel() : base() {
            _tt.AutoPopDelay = 1500;
            _tt.InitialDelay = 400;
//            _tt.IsBalloon = true;
            _tt.UseAnimation = true;
            _tt.UseFading = true;
            _tt.Active = true;
            this.MouseEnter += new EventHandler(this.ucLabel_MouseEnter);
        }

        private void ucLabel_MouseEnter(object sender, EventArgs ea)
        {
            if (!string.IsNullOrEmpty(this.TooltipText))
            {
                _tt.SetToolTip(this, this.TooltipText);
                _tt.Show(this.TooltipText, this.Parent);
            }
        }
    }

In the form or user control's InitializeComponent method (the Designer code), reassign your Label control to the custom class:

this.lblMyLabel = new ucLabel();

Also, change the private variable reference in the Designer code:

private ucLabel lblMyLabel;

Answer 2

just another way to do it.

Label lbl = new Label();
new ToolTip().SetToolTip(lbl, "tooltip text here");

Answer 3

You have to add a ToolTip control to your form first. Then you can set the text it should display for other controls.

Here's a screenshot showing the designer after adding a ToolTip control which is named toolTip1:

Answer 4

yourToolTip = new ToolTip();
//The below are optional, of course,

yourToolTip.ToolTipIcon = ToolTipIcon.Info;
yourToolTip.IsBalloon = true;
yourToolTip.ShowAlways = true;

yourToolTip.SetToolTip(lblYourLabel,"Oooh, you put your mouse over me.");

Answer 5

System.Windows.Forms.ToolTip ToolTip1 = new System.Windows.Forms.ToolTip();
ToolTip1.SetToolTip( Label1, "Label for Label1");
