c# - Calling InitializeComponent() twice in constructor -

so made simple class derived form combobox , button.

in class's constructor initializecomponent() gets fired twice follow. (just study purpose)

public form1() {      initializecomponent();      initializecomponent(); // 1 more time }  private void button1_click(object sender, eventargs e) {      messagebox.show(combobox1.text); } 

then whatever items in combobox1 click, combobox1.text string.empty.

the way solve problem seems call combobox1.dispose() between 2 initializecomponent(), , know why.

any appreciated.

thanks in advance.

look @ initializecomponents in form1.designer.cs.

if call twice, you'll have 2 combobox's. 1 may visible on can edit. other 1 (the second) 1 code refers to.

you "prove" introducing static field called counter. edit initializecomponent slightly, such moves combobox bit depending on counter , set combobox.tag counter. finally, increment counter.

however, you'll surely notice, problem of academic relevance. there's no benefit in calling initializecomponents twice.
