ToolTipController SetToolTip method question

created 16 years ago

Hello,
I am trying to use the default tooltip controller on a LabelControl. I was basing my code on this article
LabelControl
When I tried the following
ToolTipController defController = ToolTipController.DefaultController;
defController.SetToolTip(lblControl1, "Test test");
I can’t see the tooltip for the lblControl1.
The ToolTipController property for lblControl1 in the designer is not set to anything, which should allow me to use the default static controller to control the tooltips for this control, correct?
Do I have to set something else in order for me to get the tooltip working?
Thanks,
peter

    Hi,
    The SetToolTip method assigns a hint to a control, but doesn't display it. To display the hint, you need to use the ShowHint method:

    C#
    using System;  
using System.Collections.Generic;  
using System.ComponentModel;  
using System.Data;  
using System.Drawing;  
using System.Text;  
using System.Windows.Forms;  
using DevExpress.Utils;  

namespace WindowsApplication2  
{  
    public partial class Form1 : Form  
    {  
        public Form1()  
        {  
            InitializeComponent();  

            ToolTipController defController = ToolTipController.DefaultController;  
            defController.SetToolTip(labelControl1, "Test02");  
        }  
        ToolTipController defController;  
        private void Form1_Load(object sender, EventArgs e)  
        {  
            defController = ToolTipController.DefaultController;  
            defController.SetToolTip(labelControl1, "Test03");  
        }  


        private void labelControl1_MouseMove(object sender, MouseEventArgs e) {  
            defController.ShowHint(defController.GetToolTip(labelControl1), labelControl1.PointToScreen(e.Location));  
        }  
    }  
}

    Thank you, Marina

      Te suggestion you made resolved the issue. I wasn't aware that I have to explicitly make a call to show the hint - after I did that I was able to get the hint working.
      Thanks,
