c# - No control created on page_load -

i have asp page containing 2 radio buttons , other textbox , labels. things have make of them disapear (not visible) when radio button selected.

i thought using controlcollection , adding control need make invisible it. had them controlcollection, disapear web page. have no idea why.

c# code :

private void creategroup() {     controlcollection cc = createcontrolcollection();     cc.add(txt1);     cc.add(txt2);     // , on... } 

if call function on page_load() event, no control on page.

thanks

have tried setting visible=false each control in radio button selection handler?

  void yourradiobutton_checkchanged(object sender, eventargs e)    {       txt1.visible = !yourradiobutton.checked;      txt2.visible = !yourradiobutton.checked;      // , on...    } 

if want create collections of controls in page load ease manipulation, create list<webcontrol>.

list<webcontrol> yourcontrols = new list<webcontrol>(); //...  protected void page_load(object sender, eventargs e) {     yourcontrols.add(txt1);     yourcontrols.add(txt2);     // , on...  }
