Class AutoLabel

Represents a AutoLabel control with advanced customization options on background, text, and border etc.

Inheritance

System.Object

AutoLabel

Implements

IThemeProvider

IVisualStyle

Namespace: Syncfusion.Windows.Forms.Tools

Assembly: Syncfusion.Shared.Base.dll

Syntax

public class AutoLabel : Label, IThemeProvider, IVisualStyle

Remarks

Once a control is labeled by an instance of AutoLabel (through the LabeledControl property, the label gets moved around as the labeled control moves around automatically, preserving the relative positions. The relative positions can also be configured to be left, top or custom through the Position property.

Note that the FlowLayout manager will treat the label and its control as a pair, always laying them out together as if they were one single control.

Examples

using System.Windows.Forms;
namespace AutoLabel
{
    public partial class Form1 : Form
    {
        private Syncfusion.Windows.Forms.Tools.AutoLabel autoLabel1;
        public Form1()
        {
            InitializeComponent();
            //Initialization
            this.autoLabel1 = new Syncfusion.Windows.Forms.Tools.AutoLabel();
            //Set the properties
            this.autoLabel1.Text = "autoLabel1";
            this.autoLabel1.BackColor = System.Drawing.Color.DarkGray;
            this.autoLabel1.ForeColor = System.Drawing.Color.DarkBlue;
            this.autoLabel1.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
            this.autoLabel1.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;
            // Add the AutoLabel control to the form.
            this.Controls.Add(this.autoLabel1);
        }
    }
}
