How to run onclick event in asp.net from another button's javascript?

Question

Void button has a confirm box after receiving true, expecting running another button's click event however, Void2_Button_Click not run, where is wrong?

protected void Void2_Button_Click(object sender, EventArgs e)
{
        // do something    
}


Void_Button.Attributes.Add("onclick", "var agree=confirm('Confirm to void?'); if (agree){document.getElementById('Void2_Button').click();}");

This question has not been solved yet, Who can answer?

Why do you run another button's click event programatically? Isn't it better to have both buttons trigger the same event handler in code behind? — cederlof

You can also have ordinary server side click for the first button, that will simply call the click event of the other button:

<asp:Button id="Void_Button" runat="server" Text="Void" OnClick="Void_Button_Click" OnClientClick="return confirm('Confirm to void?');" />

protected void Void_Button_Click(object sender, EventArgs e)
{
   Void2_Button_Click(sender, e)
}

You would have to use the .ClientID for javascript. Try

Void_Button.Attributes.Add("onclick", "var agree=confirm('Confirm to void?'); if (agree){document.getElementById('"+Void2_Button.ClientID+"').click();}");
