checkbox status not saved when update panel fires

Question

I have an div id = campaignDiv and I load its content dynamically

The content is checkboxes .

I have an update panel that fires every 30 seconds.

Answer 1

To have more space for code here is my suggestion for the checkboxlist again. I hope it's that what you are asking for.

.aspx

.aspx.cs

if (!IsPostBack)
{
    var comps = new[] { "default", "sales", "direct" };
    for (int i = 0; i < comps.Count(); i++)
    {
         myCheckboxList.Items.Add(new ListItem{Text = comps[i]});
    }
}

This way it will keep your checkbox checked
