I have a form with levels of check boxes.  Level 1 selection enables level 2 checkboxes.  If I click level 1 and wait a long period, then click level 2 boxes I am fine or if I have stops I am fine BUT if I click too quickly then I get an page cannot be displayed.
- What is the code to determine when an autopostback is finished processing?
OR
-should I  just move the user onto the next page?
Thank you for your assistance


<asp:RadioButton ID="rdoExist"  CssClass="radio" runat="server" 
     style='left:14px; top:216px; width:181px;'  OnCheckedChanged="SetGrpZ"
            GroupName="GROUP_1" Text="Existing Business" AutoPostBack="True" />
 
public void SetGrpZ(object sender, EventArgs e)
        {
            string myCtl = ((Control)sender).ID;
 
            switch (myCtl)
            {
                case "rdoExist":
                 {
                
                chkC.Enabled = false;
                chkR.Enabled = false;
                chkA.Enabled = true;
                 break;
                 }

how can you click on the second level of check boxes if they are not even enabled yet.

Please post the full html code, it will help to analyze.

It looks like your handler is called when Page is posted.
However, your AutoPostBack is set.
need more details.

Level 1 -  User makes a radio selection of rdoNew or rdoExist which fires -Page_load & SetGrpZ
SetGrpZ disables radio New and Existing and enables checkbox chkA
If clicking chkA immediately after radio click results in:
Error 1:  chkA shows no check mark until second click
Error 2:  shows Page Cannot Be Displayed
Works fine IF - 1.  Extended period between radio click and checkbox click OR 2. Code break on SetGrpZ

how about remove SetGrpZ from chkA as a eventhandler; just a private member function instead.
In a word, call SetGrpZ in your Page_load.

You took me in another direction which ended up doing javascript and input buttons.  It is working great now.  Function was the clue.
