页面计数器 [英] Page counter

问题描述

每次页面刷新时如何递增页面计数器。



这是我的代码：

Hi,

How can I increment the page counter each time when the page gets refreshed.

Here's my code:

protected void Page_Load(object sender, EventArgs e)
    {

        if (Session["Uid"].ToString() != null)
        {
            UserId = Convert.ToInt64(Session["Uid"].ToString());
            lblCount.Text = Convert.ToString(Convert.ToInt32(lblCount.Text) + 1);
        }
        if (Session["iDataHUBID"].ToString() != null)
        {
            iDataHUBID = Convert.ToInt64(Session["iDataHUBID"].ToString());
            //lblCount.Text = Convert.ToString(Convert.ToInt32(lblCount.Text) + 1);
        }
            lblCount.Text = Convert.ToString(Convert.ToInt32(lblCount.Text) + 1);
        if (!Page.IsPostBack)
        {
            txtCDate.Text = DateTime.Now.ToString("dd/MM/yyyy");
            BindRejectReasonType();
            BindProofTypes();
            ScriptManager1.SetFocus(txtCDate);
            txtBarcode.Attributes["onchange"] = "javascript:return Barcodetest();";
            txtCAFNo.Attributes["onchange"] = "javascript:return CAFtest();";
            btnAccept.Attributes.Add("onclick", "javascript:return ValidateAccept();");
            lblCount.Text = "0";
        }
    }

问候，

推荐答案

如果页面令人耳目一新则意味着



Page.IsPostBack 条件将为假。



所以你把代码放在里面

If The page is refreshing then it means

Page.IsPostBack condition will be false.

so put you code inside

if(!Page.IsPostBack)
{
int PageRefreshCounter = 0;
Session["Counter"] = PageRefreshCounter;
}
if(Page.IsPostBack)
{

Session["Counter"] = ((int)Session["Counter"])++;
}

检查样本并相应更改代码

Check the sample and change your code accordingly

Label1.Text = "1";
        if (Session["counter"] != null)
        {
            Label1.Text = Session["counter"].ToString();
            Label1.Text = (Convert.ToInt16(Label1.Text) + 1).ToString();
        }
        if (!Page.IsPostBack)
        {
            Session["counter"] = Label1.Text;
        }
        Label1.Text = Label1.Text;
