Browser Quirk: Dynamically appended checked checkbox does not appear checked (IE)

Problem
Dynamically appended checkbox element does not appear checked despite setting the checked property state to true or "checked".

Browser
Internet Explorer

Example
The Javascript code:
Expand|Select|Wrap|Line Numbers
  1. var cb = document.createElement("input");
  2. cb.type = "checkbox";
  3. cb.name = "checkbox1";
  4. cb.id = "cbID";
  5. cb.checked = true;
  6. obj.appendChild(cb);
Solution
Use defaultChecked instead of checked:
Expand|Select|Wrap|Line Numbers
  1. cb.defaultChecked = true;
Alternative Solution
Set the checked state after appending the checkbox:
Expand|Select|Wrap|Line Numbers
  1. obj.appendChild(cb);
  2. cb.checked = true;

I have a number of input boxes used to display totals based on selected items for each row in a table. There are more than a few rows that are identical, except for the form field name. I have added a sample of that below (there would be many more rows). I'm wondering if there is a way to dynamically generate the variable names (ie: T1val, T2val, etc.) in my function 'calc', based on the argument 'regnum' that I pass it. The problem...

I'm extremely frustrated with ASP.NET...again! To me this should be as simple as setting oCheckBox.Checked = True.. yet for some reason it isn't. I have a user control (ascx) that that has a checkbox and I can't get it to default to checked. I tried radiobuttons and experienced the same result.. can't start them as checked. The really frustrating thing is that I set the attributes of other input controls in the Init() with no problem. ...

Hello All, I am programmatically building a table on my web page with one row and two columns. The first column contains a web server checkbox dynamically created and the second column simply contains text of whatever I put in. This is running fine. If I check the checkbox, how would I check if this checkbox is checked or not during postback? The dynamically created checkbox seems to have disappeared during postback.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
