Hi,
I'm trying to implement F11 feature - full screen in my application.
It works like a charm for standard .NET Form, but for RadForm I have some inaccuracy.
Win7 x64 - on the top of the screen I see part of title bar which should be normally hidden by calling "targetForm.FormBorderStyle = FormBorderStyle.None;".
WinXP - on the top I still can see like 2px space from title bar, but more important is that it doesn't cover Windows taskbar in the bottom of the screen.
The Code is simple:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using Telerik.WinControls;
using Telerik.WinControls.UI;
namespace RadControlsWinFormsApp1
{
public partial class RadForm1 : RadForm
{
public FormState fs = new FormState();
public RadForm1()
{
InitializeComponent();
}
private void radButton1_Click(object sender, EventArgs e)
{
fs.Maximize(this);
}
private void radButton2_Click(object sender, EventArgs e)
{
fs.Restore(this);
}
}

public class WinApi
{
[System.Runtime.InteropServices.DllImport("user32.dll", EntryPoint = "GetSystemMetrics")]
public static extern int GetSystemMetrics(int which);
[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern void
SetWindowPos(IntPtr hwnd, IntPtr hwndInsertAfter,
int X, int Y, int width, int height, uint flags);
public static void SetWinFullScreen(IntPtr hwnd)
{
SetWindowPos(hwnd, IntPtr.Zero, 0, 0, GetSystemMetrics(0), GetSystemMetrics(1), 64);
}
}
/// <summary>
/// Class used to preserve / restore state of the form
/// </summary>
public class FormState
{
private FormWindowState winState;
private FormBorderStyle brdStyle;
private bool topMost;
private Rectangle bounds;
public bool IsMaximized = false;
public void Maximize(RadForm targetForm)
{
if (!IsMaximized)
{
IsMaximized = true;
Save(targetForm);
targetForm.WindowState = FormWindowState.Maximized;
targetForm.FormBorderStyle = FormBorderStyle.None;
targetForm.TopMost = true;
WinApi.SetWinFullScreen(targetForm.Handle);
}
}
public void Save(RadForm targetForm)
{
winState = targetForm.WindowState;
brdStyle = targetForm.FormBorderStyle;
topMost = targetForm.TopMost;
bounds = targetForm.Bounds;
}
public void Restore(RadForm targetForm)
{
targetForm.WindowState = winState;
targetForm.FormBorderStyle = brdStyle;
targetForm.TopMost = topMost;
targetForm.Bounds = bounds;
IsMaximized = false;
}
}
}
When you replace RadForm by Form everything is all right on both OS :-(
Any idea, any help?
Thanks Zbyněk
