function

Hi,
I have this function for a ToolStripMenu When a button is selected, the function will search to see if

there is some other button selected, and will deselect it:

private void button1ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (button1ToolStripMenuItem.Checked)
            {
             button1ToolStripMenuItem1.Checked = false;
             button1ToolStripMenuItem2.Checked = false;
             button1ToolStripMenuItem3.Checked = false;
             button1ToolStripMenuItem4.Checked = false;
             button1ToolStripMenuItem5.Checked = false;
             ..........................
             button1ToolStripMenuItem30.Checked = false;
             
                
            }
        }
private void button1ToolStripMenuItem1_Click(object sender, EventArgs e)
        {
            if (button1ToolStripMenuItem.Checked)
            {
             button1ToolStripMenuItem.Checked = false;
             button1ToolStripMenuItem2.Checked = false;
             button1ToolStripMenuItem3.Checked = false;
             button1ToolStripMenuItem4.Checked = false;
             button1ToolStripMenuItem5.Checked = false;
             ..........................
             button1ToolStripMenuItem30.Checked = false;
             
                
            }
        }


......................


private void button1ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (button30ToolStripMenuItem.Checked)
            {
             button1ToolStripMenuItem1.Checked = false;
             button1ToolStripMenuItem2.Checked = false;
             button1ToolStripMenuItem3.Checked = false;
             button1ToolStripMenuItem4.Checked = false;
             button1ToolStripMenuItem5.Checked = false;
             ..........................
             button1ToolStripMenuItem29.Checked = false;
             
                
            }
        }

private void button2ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (button2ToolStripMenuItem.Checked)
            {
             button2ToolStripMenuItem1.Checked = false;
             button2ToolStripMenuItem2.Checked = false;
             button2ToolStripMenuItem3.Checked = false;
             button2ToolStripMenuItem4.Checked = false;
             button2ToolStripMenuItem5.Checked = false;

             button2ToolStripMenuItem30.Checked = false;
             
                
            }
        }

You can give them all the same event, deselect all the items that are not the 'sender'

private void button1ToolStripMenuItem_Click(object sender, EventArgs e){
   ToolStripMenuItem sender_item = sender as ToolStripMenuItem;
   foreach (ToolStripMenuItem item in toolStrip1.Items) {
      item.Checked = (item.Name == sender_item.Name);
   }
}

thank you dannystommen
the problem is that i don't know how to create the declaration for

 ContainerButton1
{
             button1ToolStripMenuItem1;
             button1ToolStripMenuItem2;
                          ..........................
             button1ToolStripMenuItem30;
}

 ContainerButton2
{
             button2ToolStripMenuItem1;
             button2ToolStripMenuItem2;
                          ..........................
             button2ToolStripMenuItem30;
}

etc...

when i select button1ToolStripMenuItem1 from ContainerButton1 i don't want to deselect anny buttons from container2 , container 3 etc...
