if i were using an Ajax control i'd do this with a CSS file some thing like this
.WindowsStyle .ajax__combobox_inputcontainer
{
}
.WindowsStyle .ajax__combobox_textboxcontainer
{
width: 100%;
}
.WindowsStyle .ajax__combobox_textboxcontainer input
{
width: 100%;
font-size: 16px;
font-family: Verdana;
}
.WindowsStyle .ajax__combobox_buttoncontainer
{
}
.WindowsStyle .ajax__combobox_buttoncontainer button
{
background-position: center;
background-repeat: no-repeat;
border-color: ButtonFace;
height: 15px;
width: 15px;
background-image: url('../Images/download.jpg');
}
.WindowsStyle .ajax__combobox_itemlist
{
width:50%;
margin: 0px;
padding: 0px;
cursor: default;
list-style-type: none;
text-align: left;
border: solid 1px ButtonShadow;
background-color: Window;
}
.WindowsStyle .ajax__combobox_itemlist li
{
white-space: nowrap;
padding: 0 3px 0 2px;
}
.ajax__combobox_itemlist
{
padding: 0%;
cursor: default;
list-style-type: none;
text-align: left;
border: solid 1px ButtonShadow;
background-color: Window;
font-size: 16px;
font-family: Verdana;
width: 50%;
}
then set the CSSClass = WindowsStyle
there must be something similar in Ext
