Server control width won't apply with IE11 ? - html

Question

I have this simple server control with a valid Width attribute : ( asp.net 4 , vs2010 )
<asp:TextBox runat="server" ID="TXT_UserName" Width="250px"></asp:TextBox>
On all browsers (all + ie<11) it does render as it should with the appropriate Width
But with ie11 ( windows 8.1 ) it wont render as it should : (it's even not in the view source ) :
Here is how I see it in other browsers ( including ie<11)
I've already added (for past problems which are now solved) the App_Browsers folder with the appropriate files for compatibility with IE versions :
Question :
Why I'm not seeing the width attribute and how can I fix it ?

Answer 1

Hmm...can't reproduce your error, and I don't have any special App_Browser folder, though I'm on VS2012 (4.5):
<asp:TextBox ID="styletextbox1" runat="server" Width="250px"></asp:TextBox>
Render Source (ie11):
<input name="ctl00$MainContent$styletextbox1" type="text" id="MainContent_styletextbox1" style="width:250px;" />
Dev tools (ie11):
So our diff are:
VS2012
4.5
App_Browser
Hth...

Answer 2

I had the same issue and fixed.
Your App_Browsers folder should contain:
firefox.browser, ie.browser, and ie11.browser
The ie11.browser content:
<browsers>
<browser id="IE11" parentID="Mozilla">

<userAgent match="Trident\/7.0; rv:(?'version'(?'major'\d+)(\.(?'minor'\d+)?)(?'letters'\w*))(?'extra'[^)]*)" />
<userAgent nonMatch="IEMobile" />
</identification>
<capture>
<userAgent match="Trident/(?'layoutVersion'\d+)" />
</capture>
<capabilities>
