c# - Remove images appearing on the aspx page -

i created imagebuttons in code-behind. then, populated list of imagebuttons as:

    protected void image_click(object sender, imageclickeventargs e)     {         imagebutton imgbutton = sender imagebutton;         imgbutton.imageurl = resource.tick_image;           // work          imagebuttonlist.add(imgbutton);     } 

on aspx page images appear now. after time, want remove images.

i tried like:

buttonlist.clear(); 

but, still images appearing on aspx page. how should remove images?

my whole code looks like:

public static list<image> randomimages = new list<image>();  protected void page_load(object sender, eventargs e) {     buttonlist.clear();        if (!string.isnullorempty(request.form[resource.reset_button_id]) || !page.ispostback)       {           randomimages = resetgame();       }       addcardstodisplay(randomimages, carddiv, true); }  public void addcardstodisplay(list<image> images, system.web.ui.htmlcontrols.htmlgenericcontrol divisionname, bool isclickable) {     foreach (var image in images)     {         imagebutton button = utilities.createimagebutton(image.newimageurl, image.id, carddiv);         addimagebuttonclickevent(button, isclickable);     } }   protected list<image> resetgame() {     numberofclicks = 0;     return getrandomimages(number_of_images); }      public static imagebutton createimagebutton(string imageurl, string id, system.web.ui.htmlcontrols.htmlgenericcontrol divisionname)     {         imagebutton button = new imagebutton { imageurl = imageurl, id = id };         divisionname.controls.add(button);         return button;     } 

just use command "clear" list. empty usages pf buttons. instead of foreach loop

 imagebuttonlist.clear(); 

and should work. :-)

edit

i thought imagelist parent of controls. not seem case.

if want remove button itself, try as:

 imgbutton.parent.controls.remove(imgbutton); 

if want hide them. do

 imgbutton.visible = false; 

last not least. can reset image url, set null. , shouldmt visible (not sure if give red x though)
