Hi,
First of all you should add System.Design dll into your references and than if you design your button code as below,at the time you drag and drop your button on the form you will see your text on the button.
[Designer(typeof(MyButtonDesigner))]
class MyButton : Button
{
}
public class MyButtonDesigner : System.Windows.Forms.Design.ControlDesigner
{
public override void OnSetComponentDefaults()
{
base.OnSetComponentDefaults();
Control.Text = "Demo Button";
}
}
Thanks
