有什么办法可以在Winforms中执行Slider.AutoToolTipPlacement之类的操作吗？

Question

I'm wondering if there is any way to have the value of a slider displayed in tooltip when the thumb is moved on a slider in winforms? It seems to be doable in wpf ( MSDN ). Right now I'm just displaying it in a text box to the side, but I would like a more visually minimal way of doing it. Thanks

Assuming you are using a Trackbar and a Tooltip in your form, you could use the following code :

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        this.trackBar1.ValueChanged += trackBar1_ValueChanged;
    }

    void trackBar1_ValueChanged(object sender, EventArgs e)
    {
        // Force the ToolTip text to be displayed whether or not the form is active.
        toolTip1.ShowAlways = true;

        // Set up the ToolTip text for the Button and Checkbox.
        toolTip1.SetToolTip(this.trackBar1, trackBar1.Value.ToString());
    }
}
