Question

I am using a JavaScript virtual keyboard for an ASP.NET TextBox. But using a TextBox gives an option to use even system keyboard. I am trying to use an ASP.NET label instead but its not working. Is there any way to make use of virtual keyboard strictly.

Answer 1

Make your textbox read only.

This way your user can not type in, but the javascript from the virtual keyboard can write. This is not a very good lokking user interface thow.

Using Javascript

Second trick is to use the the onkeypress and delete the key. You can add window.event.keyCode=0 on the TextBox when the key is pressed and reset every user input.

onkeypress="window.event.keyCode=0;return false;"

Like this

<asp:TextBox runat="server" ID="txtTest2" 
  onkeypress="window.event.keyCode=0;return false;"></asp:TextBox>

New Version

This is works on every browser. I tested on chrome,firefox,ie

<script>
function DisableKeyboardOnMe(e)
{   
    try
    {
        if (window && window.event)
            window.event.keyCode = 0;
        else
            e.which = 0;
    }
    catch(e){} 

    return false;
}   
</script>

and

<asp:TextBox runat="server" ID="txtTest3" 
    onkeypress="return DisableKeyboardOnMe(event);">test</asp:TextBox>

One more simple way.

I tested on all my browsers and this is working also.

 <asp:TextBox runat="server" ID="txtTest4" 
      onkeypress="return false;"></asp:TextBox>
