ASP. NET, CheckBoxList choice is automatic width, didn’t set the width attribute set. Referring to the minimum width style of 1 network,

/*  Minimum �  */
.min_width{min-width:300px;
/* sets max-width for IE */
_width:expression(document.body.clientWidth < 300 ? "300px" : "auto");
}

It is written as follows:

<style>
.ckblstEffect td
{
min-width:80px;
_width:expression(document.body.clientWidth < 80 ? "80px" : "auto");
}
</style>

<asp:CheckBoxList ID="ckblstEffect" runat="server" DataTextField="MC"
RepeatDirection="Horizontal" RepeatColumns="10" CssClass="ckblstEffect"
DataValueField="ID" ondatabound="ckblstEffect_DataBound">
</asp:CheckBoxList>

This doesn’t work in Maxthon 4 compatibility mode (IE7), but if you look closely at the expressions in the styles, it doesn’t work at all. Just change to the following style.

<style>
.ckblstEffect td
{
min-width:80px;
width:expression(this.offsetWidth < 80 ? "80px" : "auto");
}
</style>

Minimum width displays correctly in IE10, Max speed 4 and compatible modes. This style can be used for CheckBoxList, DIV, etc.

Please let me know if you find that other browsers cannot display the CheckBoxList minimum width.
