在 C # WinForms 中切换按钮

You can always code your own button with custom graphics and a PictureBox, though it won't necessarily match the Windows theme of your users.

Check FlatStyle property. Setting it to "System" makes the checkbox sunken in my environment.

You may also consider the ToolStripButton control if you don't mind hosting it in a ToolStripContainer. I think it can natively support pressed and unpressed states.

I ended up overriding the OnPaint and OnBackgroundPaint events and manually drawing the button exactly like I need it. It worked pretty well.

You can just use a CheckBox and set its appearance to Button:

CheckBox checkBox = new System.Windows.Forms.CheckBox();
checkBox.Appearance = System.Windows.Forms.Appearance.Button;

thers is a simple way to create toggle button. I test it in vs2010. It's perfect.

ToolStripButton has a "Checked" property and a "CheckOnClik" property. You can use it to act as a toggle button

tbtnCross.CheckOnClick = true;

OR

    tbtnCross.CheckOnClick = false;
tbtnCross.Click += new EventHandler(tbtnCross_Click);
.....


void tbtnCross_Click(object sender, EventArgs e)
{
ToolStripButton target = sender as ToolStripButton;
target.Checked = !target.Checked;
}

also, You can create toggle button list like this:

        private void Form1_Load(object sender, EventArgs e)
{
arrToolView[0] = tbtnCross;
arrToolView[1] = tbtnLongtitude;
arrToolView[2] = tbtnTerrain;
arrToolView[3] = tbtnResult;
for (int i = 0; i<arrToolView.Length; i++)
{
arrToolView[i].CheckOnClick = false;
arrToolView[i].Click += new EventHandler(tbtnView_Click);
}
InitTree();
}


void tbtnView_Click(object sender, EventArgs e)
{
ToolStripButton target = sender as ToolStripButton;
if (target.Checked) return;
foreach (ToolStripButton btn in arrToolView)
{
btn.Checked = false;
//btn.CheckState = CheckState.Unchecked;
}
target.Checked = true;
target.CheckState = CheckState.Checked;


}

Changing a CheckBox appearance to Button will give you difficulty in adjustments. You cannot change its dimensions because its size depends on the size of your text or image.

You can try this: (initialize the count variable first to 1 | int count = 1)

private void settingsBtn_Click(object sender, EventArgs e)
{
count++;


if (count % 2 == 0)
{
settingsPanel.Show();
}
else
{
settingsPanel.Hide();
}
}

It's very simple but it works.

Warning: This will work well with buttons that are occasionally used (i.e. settings), the value of count in int/long may be overloaded when used more than it's capacity without closing the app's process. (Check data type ranges: http://msdn.microsoft.com/en-us/library/s3f49ktz.aspx)

The Good News: If you're running an app that is not intended for use 24/7 all-year round, I think this is helpful. Important thing is that when the app's process ended and you run it again, the count will reset to 1.

How about this?

Assuming you have System.Windows.Forms referenced.

var cbtnToggler = new CheckBox();
cbtnToggler.Appearance = Appearance.Button;
cbtnToggler.TextAlign = ContentAlignment.MiddleCenter;
cbtnToggler.MinimumSize = new Size(75, 25); //To prevent shrinkage!

Hope this helps ;)

use if command to check status and let operate as a toggle button

private void Protection_ON_OFF_Button_Click(object sender, EventArgs e)
{


if (FolderAddButton.Enabled == true)
{
FolderAddButton.Enabled = false;
}
else
{
FolderAddButton.Enabled = true;
}
}

This is my simple codes I hope it can help you

private void button2_Click(object sender, EventArgs e)
{
if (button2.Text == "ON")
{
panel_light.BackColor = Color.Yellow; //symbolizes light turned on


button2.Text = "OFF";
}


else if (button2.Text == "OFF")
{
panel_light.BackColor = Color.Black; //symbolizes light turned off


button2.Text = "ON";
}
}

When my button's FlatStyle is set to system, it looks flat. And when it's set to popup, it only pops up when mouses over. Either is what I want. I want it to look sunken when checked and raised when unchecked and no change while mousing over (the button is really a checkbox but the checkbox's appearance property is set to button).

I end up setting the FlatStyle to flat and wrote a new Paint event handler.

 private void checkbox_paint(object sender, PaintEventArgs e)
{
CheckBox myCheckbox = (CheckBox)sender;
Rectangle borderRectangle = myCheckbox.ClientRectangle;
if (myCheckbox.Checked)
{
ControlPaint.DrawBorder3D(e.Graphics, borderRectangle,
Border3DStyle.Sunken);
}
else
{
ControlPaint.DrawBorder3D(e.Graphics, borderRectangle,
Border3DStyle.Raised);
}
}

I give a similar answer to this question: C# winforms button with solid border, like 3d Sorry for double posting.

You should look into Siticone I use it and I love it. It works exactly like a checkbox but is a toggle button. Its downside is a message box will come up every time you open Visual Studios so I just installed a tool that disables it. You can also look into Guana but I found that to have a few bugs :)
