Create pressed-in buttons in c#

hi
if you want to change the button appearence then you have to use some another method from outside. 

for this use two images, one looks like pressed button and another like released button (up). and then use if...else condition in code-behind to switch between them. 

hope this helps

Try this

public partial class Form1 : Form
{
bool bttnclicked = false;
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
toolStripButton1.BackColor = Color.Green;
}

private void toolStripButton1_Click(object sender, EventArgs e)
{
if (!bttnclicked)
{
toolStripButton1.BackColor = Color.Red;
bttnclicked = true;
}
else
{
toolStripButton1.BackColor = Color.Green;
bttnclicked =false;
}
}


}

there is button control there in toolstrip Control . you can control its toggle by Checked and Unchecked Property
