c# - AjaxControlToolkit ComboBox cannot be enabled after disabling -

-

i have ajaxcontroltoolkit combobox follows:

<atc:combobox   id="cmbid1"   runat="server"   width="150px"   rendermode="block"   dropdownstyle="dropdownlist"   autocompletemode="suggestappend"> </atc:combobox>

elsewhere on page, have checkbox want use toggle combobox:

<asp:checkbox   id="lockcheckbox"   runat="server"    text="locked"   enabled="false"    oncheckedchanged="lockcheckbox_checkedchanged"   autopostback="true" />

then have handler this:

protected void lockcheckbox_checkedchanged(object sender, eventargs e) {     if (lockcheckbox.checked)     {         cmbid1.enabled = false;          enablecontrolnotlockeddown();     }     else     {         cmbid1.enabled = true;     } }

instead of toggling combobox enabled disabled , vice versa, comobox gets disabled , never becomes enabled again.

what doing wrong?

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
