问题 This causes the same item to be added to the array - which is used for querying - potentially twice. When the modal is closed and opened again and filtering is not used, everything is fine (this is because my modals are simply within the HTML, I just ng-hide them on click). When an item which has already been added, but its checkmark has been lost due to filtering, is checked again two of the same items are added. When it is unchecked both are removed, unless it is the last item in the array,

问题 I have a listview, with around 200 items, I have implemented a custom ArrayAdapter for the checkboxes. I use a SparseBooleanArray to store the value of the boxes. All of this works fine but I cannot seem to graphically update the checking of the boxes. If the user clicks, then the box is checked. But, if I call setChecked in my code, it has no impact on the box itself (so, even if its value is true, then it is not ticked). I have tested by trying to set all boxes to true and no luck, even

问题 I have a page with a table of stuff and I need to allow the user to select rows to process. I've figured out how to add a column of check boxes to the table but I can't seem to figure out how to test if they are checked when the form is submitted.

Also I'm not very happy with how I'm attaching my data to them (by stuffing it in there ID property). I'm not sure if it's relevant but

How to make checkbox checked by default? 回答1: Ok, I've debbuged a while and found a solution, it lies in the guts of BaseHtml.php at line 1359 in

问题 I have 5 to 6 check boxes (active x) in a row and I have 50 rows. Is there a way to make only one checkbox tick-able in a row ( only one answer either 1,2,3,4 or 5)?. Any simple vba to do this , I don't want to write a code to every checkbox. 回答1: Yes, it can be done BUT Why use ActiveX Controls and so much extra coding? Why not data validation list? See this screenshot If you still want a VBA Solution then I would recommend using FORM Controls and use their ALT Text to configure it. I infact
