CssClass的ASP.net按钮不起作用

Question

Problem:

I have two ASP.net Buttons that work fine in the Chrome and Firefox browser but not in IE 9.0.

*Does not work on IE 9.0*
<asp:Button ID="btnMeal" runat="server" onclick="btnMeal_Click" Text="." CssClass="buttonmeal" />

*Works fine on IE 9.0 and other browsers*
<asp:Button ID="btnType" runat="server" onclick="btnType_Click" Text="." CssClass="button"/>

CSS Code:

/*Doesnt work*/
.buttonmeal
 {
        background: url('../images/meal.png') no-repeat;
        width:82px;
        height:32px;
        border:0px;     
    }

/*Works*/
    .button
    {
        background: url('../images/type.png') no-repeat;
        width:82px;
        height:32px;
        border:0px;     
    }

Maybe I think the problem is because it renders in IE differently and only button is used in IE.

<td class="myStyle">
    <input type="button" name="select" ...>
</td>

Most likely a caching issue (it was for me anyway). There's a good change your browser is not using the newest version of your CSS file. Try a hard refresh:

Chrome / IE / Firefox : Ctrl + R
