1，confirm()在.net的button中的使用。
（1）对System.Web.UI.WebControls.Button button3控件
因为它的click事件是服务器端的，首先在服务器端给button绑上客户端的事件，代码是:
this.Button3.Attributes.Add("onclick","return confirm('aa')");
如此即可
（2）对protected Infragistics.WebUI.WebDataInput.WebImageButton WebImageButton2;
需要在客户端给click事件加上WebImageButton2_Click方法，该方法代码:
function WebImageButton2_Click(oButton, oEvent)
{ //Add code to handle your event here.
if(!confirm("dddd"))
oEvent.needPostBack=false;
else
oEvent.needPostBack=true;
}
2，对该protected Infragistics.WebUI.WebDataInput.WebDateTimeEdit idteDateTime; 控件的使用
效果就是在单击右侧按钮后，出现protected Infragistics.WebUI.WebSchedule.WebCalendar SharedCalendar;控件，即下拉的时间表；这主要是客户端的代码，如下：
//建立一个protected Infragistics.WebUI.WebDataInput.WebDateTimeEdit idteDateTime; 控件
<igtxt:webdatetimeedit id="idteDateTime" runat="server" EditModeFormat="D" DisplayModeFormat="D" Width="128px" Fields="2005-7-14-0-0-0-0">
<ButtonsAppearance CustomButtonDisplay="OnRight"></ButtonsAppearance>
<SpinButtons Display="OnRight"></SpinButtons></igtxt:webdatetimeedit>
//建立一个protected Infragistics.WebUI.WebSchedule.WebCalendar SharedCalendar;控件
