POST arrays not showing unchecked Checkboxes
That behavior is not surprising, as the browser doesn’t submit any value for checkboxes that are unchecked. If you are in a situation where you need to submit an exact number of elements as an array, why don’t you do the same thing you do when there’s an id of some sort associated with each … Read more

Checkbox auto call onCheckedChange when listview scroll?
The ListView recycles the view classes: you will need to explicitly set whether or not the CheckBox is checked in the getView class. So add a check like /** * Ensure no other setOnCheckedChangeListener is attached before you manually * change its state. */ mViewHolder.checkbox.setOnCheckedChangeListener(null); if(shouldBeChecked) mViewHolder.checkbox.setChecked(true); else mViewHolder.checkbox.setChecked(false); before you call setOnCheckedChangeListener.

Unchecked checkboxes are not posted, so the hidden field (set as false) allows the model binding to still work. Look at Request.Form on the post back. If the checkbox is checked, you’ll see: ChxName=true&ChxName=false The model binder uses the first value. and, if the box isn’t checked, you’ll see: ChxName=false
How to implement a button that gets all checkbox’s state and adds the value of checked item into arraylist?
