c# - Dynamically added CheckBoxes to a CheckBoxList not showing Text -

following code adding checkboxes dynamically checkboxlist:

foreach (wcore.categoryfields cat in global.getcategories()) {         checkbox c = new checkbox();         c.text = cat.categoryid;         c.tag = cat.categoryname;         if (ints != null)         {             if (ints.contains(c.tag))                invoke(new action(()=>checkedlistbox1.items.add(c, true)));             else                invoke(new action(()=>checkedlistbox1.items.add(c, false)));         }         else             invoke(new action(()=>checkedlistbox1.items.add(c, false))); } 

the problem whenever run code, checkboxes added not text. this:

i tried debug , found checkbox instance 'c' getting text not showing it.

see here:

please tell me what's wrong going on in code?

update

please note can't use this:

invoke(new action(()=>checkedlistbox1.controls.add(c))); 

because better use panel instead of checkboxlist then. want 2 values 1 shown text , other hidden value each checkbox in checkboxlist

update 2

code selected items:

list<string> selints = new list<string>(); foreach (listboxitem c in checkedlistbox1.selecteditems) {         selints.add(c.tag.tostring()); } 

try this:

foreach (wcore.categoryfields cat in global.getcategories()){     listboxitem c = new listboxitem;     c.text = cat.categoryid;     c.tag = cat.categoryname;     if (ints != null)     {         if (ints.contains(c.tag))            invoke(new action(()=>checkedlistbox1.items.add(c, true)));         else            invoke(new action(()=>checkedlistbox1.items.add(c, false)));     }     else         invoke(new action(()=>checkedlistbox1.items.add(c, false))); } //add class somewhere in form class or beside public class listboxitem {    public string text {get;set;}    public object tag {get;set;}    public override string tostring(){       return text;    } } 

i doubt somehow checkbox can't displayed string although should show system.windows.forms.checkbox instead of blanks.
