首先设计一个容错提示的窗口图像为如下:
关键HTML文本如下:
“原因:<%=content[Int32.Parse(Request.QueryString["ms"])]%>”
然后在代码编辑窗口中添加如下不分:
public class WebForm1 : System.Web.UI.Page
{
public string[] content;
private void Page_Load(object sender, System.EventArgs e)
{
content=new string[10];
content[1]=".提示1.";
content[2]="提示2";
... ...
}
===========================================
在容错的网页中这样调用:
[/*以下是一个示例!*/]
public void Check()
{//检测用户输入的合法性;
//检测[订单号][类型]是否为空白;
if (lOrderName.InnerText.Trim() == "" || lOrderCategory.InnerText.Trim() == "")
{
Response.Redirect(@"..\Exceptions.aspx?ms=11");
}
//判断用户输入的数量是否正确;
try
{
int i = Convert.ToInt16(tbQuantity.Text);
if (i ==0)
{
Response.Redirect(@"..\Exceptions.aspx?ms=12");
}
}
catch
{
Response.Redirect(@"..\Exceptions.aspx?ms=12");
}
//判断日期是否正确;
try
{
Convert.ToDateTime(tbTerm.Text);
}
catch
{
Response.Redirect(@"..\Exceptions.aspx?ms=9");
}
//判断交货期必须大于开单日期;
if (Convert.ToDateTime(tbTerm.Text) < Convert.ToDateTime(Request.Cookies["Order"].Values["Date"]))
{
Response.Redirect(@"..\Exceptions.aspx?ms=14");
}
//判断当前的型号在当前订单中是否已经存在;
DataClass dc = new DataClass();
if (dc.CheckModel(lOrderName.InnerText,lbModel.SelectedValue.ToString()))
{
Response.Redirect(@"..\Exceptions.aspx?ms=13");
}
//当订单类型为:“S-P”时,检测不能超出上限;
if (lOrderCategory.InnerText=="S-P")
{
if (Convert.ToInt32(tbQuantity.Text) > Convert.ToInt32(lbUpper.InnerText))
{
Response.Redirect(@"..\Exceptions.aspx?ms=18");
}
}
}
==========================================
其中Exceptions.aspx就是我们刚才定义的那个容错窗口了!
