WebBrowser control inherits display style from control class. If you want to control the border style of control, you can use code like that, e.g. in Form.Designer.cs:
using System;
using System.ComponentModel;
using System.Windows.Forms;
public class wbExt : System.Windows.Forms.WebBrowser
{
private BorderStyle _borderStyle;
[
Category("Appearance"),
Description("The border style")
]
public BorderStyle BorderStyle
{
get
{
return _borderStyle;
}
set
{
_borderStyle = value;
this.RecreateHandle();
Invalidate();
}
}
protected override CreateParams CreateParams
{
get
{
const int WS_BORDER = 0x00800000;
const int WS_EX_STATICEDGE = 0x00020000;
CreateParams cp = base.CreateParams;
switch (_borderStyle)
{
case BorderStyle.FixedSingle:
cp.Style |= WS_BORDER;
break;
case BorderStyle.Fixed3D:
cp.ExStyle |= WS_EX_STATICEDGE;
break;
}
return cp;
}
}
public wbExt()
{
}
}
Now you can change generated code in Form class.
private wbExt webBrowser1;
and rewrite creation of webBrowser item in InitializeComponent of form, like that:
this.webBrowser1 = new WindowsFormsApplication1.wbExt();
So, now
webBrowser1.BorderStyle = BorderStyle.None;
will remove any borders from webBrowser control.
