C#: How do I add a ToolTip to a control?


Answers

Drag a tooltip control from the toolbox onto your form. You don't really need to give it any properties other than a name. Then, in the properties of the control you wish to have a tooltip on, look for a new property with the name of the tooltip control you just added. It will by default give you a tooltip when the cursor hovers the control.

Question

I have some controls that I would like to display a ToolTip for when the mouse is hovering over it. How can I do this? I would like to know how to do this properly in code, but also in the designer (There is a ToolTip component in the toolbox, but I don't quite.. get it).

I wouldn't be surprised if this is a duplicate, but I can only find questions that are on more advanced, specific scenarios. I would like to know the basics.




ToolTip in C# is very easy to add to almost all UI controls. You don't need to add any MouseHover event for this.

This is how to do it-

  1. Add a ToolTip object to your form. One object is enough for the entire form. ToolTip toolTip = new ToolTip();

  2. Add the control to the tooltip with the desired text.

    toolTip.SetToolTip(Button1,"Click here");
