Drag and drop html elements into SpellAsYouType textbox.
If a user selects html items on the screen, they are able to drop them into the spellAsYouType textbox.

This can be shown on your Spell As You Type sample page.  Drag the SpellWaitPeriod dropdown into the spell textbox.

Is there anything that can be done  to prevent this?

Re: Drag and drop html elements into SpellAsYouType textbox.
Yes, you can prevent drag-and-drop using the UltimateSpell client-side API functionality. You should define ondrop event handler and cancel the event when it fires as follows:

<script type="text/javascript">
function <%=UltimateSpell1.ClientID%>_OnLoad() {
   UltimateSpellAsYouTypes['TextBox1'].AddEventHandler('drop', function(evnt) { HandleDrop(evnt); });
}

function HandleDrop(evnt) {
   UltimateSpellAsYouTypes['TextBox1'].CancelEvent(evnt);
}
</script>

You need to replace UltimateSpell1 with the server-side ID of your UltimateSpell control and replace TextBox1 with the client-side ID of your text area control.

Please also note that we made some minor changes in our JavaSCript code, which we will email you shortly.

Re: Drag and drop html elements into SpellAsYouType textbox.
I too am trying to prevent users from being able to drag controls, images, selected items and drop them into the SAYT field.  I tried the example you gave using the code below:

function UltimateSpell1_OnLoad()
{ 
   alert(1);
   UltimateSpellAsYouTypes['txtSpellCheckField'].AddEventHandler('drop',function (evnt) {HandleDrop(evnt)});
   alert(2);
}
function HandleDrop(evnt) 
{
   alert('txtSpellCheckField');
   UltimateSpellAsYouType['txtSpellCheckField'].CancelEvent(evnt);
}

with no avail.  The following is the html for my textbox that the spellcheck is on.

<input name="txtSpellCheckField" type="text" maxlength="255" id="txtSpellCheckField" />

This is the "View Source" of the control from IE (not from Visual Studio).  I just colored it to make it easier to read.

My server control is done this way:
<asp:TextBox AutoPostBack=False MaxLength=255 ID=txtSpellCheckField Runat=server></asp:TextBox>

I see the alerts "1" and "2" just fine.  But if I drag something into the SAYT field it drops just fine.  I never get the alert of "txtSpellCheckField".  Can someone identify what I am doing wrong?

It is because we haven't published the latest JavaScript files on our website yet. We will send you a patch shortly.
