This problem is quite odd and we have not received such reports so far. I tried to reproduce the problem in my local tests by viewing the live sample version of FirstExperience.aspx in Firefox 16.01 and Chrome 22 but my efforts were not successful -- everything worked smoothly and the reported appearing-textbox control is not reproducible.

I’m willing to advise you further but in order to do so I would need you to elaborate on your specific scenario and possibly give us a step-by-step guide that we can use to observe the problematic behavior.

Is there a element called webgrid1_Moz assocated with the webGrid?  I have no elements with that name on my pages.  Is there code within webGrid:

<input onkeydown="WGUI.TBKDMZ()" onkeypress="WGUI.TBKPMZ()" id="ctl00_MainContent_WebGrid1_Moz" style="position: absolute; top: -500px; left: -500px;" type="text">

Also you need to use XHTML doc type

I'll try to see if I can modify a sample to show it, but as you can cleary see in my image it does appear.

... <input onkeydown="WGUI.TBKDMZ()" onkeypress="WGUI.TBKPMZ()" id="ctl00_MainContent_WebGrid1_Moz" style="position: absolute; top: -500px; left: -500px;" type="text"> ...

It is the textbox element which is used by WebGrid when user edits a cell. The element is supposed to be hidden and unexpectedly appearing in the viewable area of your browser (Firefox and Chrome).

You may try to hide the element by adding following css in the page.

<style type="text/css">
    #ctl00_content_WebGrid1_Moz
    {
        z-index: -1;
        display: none;
    }
</style>

I have tested this workaround in my local end and so far found no problem. Please let us know whether this helps or not.

Yudi,

  that hides the textbox.  Thanks

Glad to hear that the trick to add css selector which pointed to the corresponding textbox element successfully hides the box.
