Answer 1

You're better off having a common method that both of your control handlers call, rather than trying to call one handler from another. That way your code is more extensible and testable, and you don't have to worry about the event arguments or senders.

For example:

private void btnSubmit_Click(object sender, EventArgs e)
{
    DoStuff();
}

private void axTws1_tickPrice(object sender, AxTWSLib._DTwsEvents_tickPriceEvent e)
{    
    if (Condition)
    {
        DoStuff();
    }
}

private void DoStuff()
{
    // code to do stuff common to both handlers
}

Answer 2

Multiple options.

Option 1 :

Preferred approach, move common logic to another method.

private void btnSubmit_Click(object sender, EventArgs e)
{
    CommonLogic();
}

private void axTws1_tickPrice(object sender, AxTWSLib._DTwsEvents_tickPriceEvent e)
{    
    if (Condition)
    {
        CommonLogic();
    }
}

private void CommonLogic()
{
    // code for common logic
}

Option 2:

Executing PerformClick() method which generates a Click event for a button.

btnSubmit.PerformClick();

Option 3:

Invoke the event method like any other normal method.

btnSubmit_Click(sender, new EventArgs());
