为什么模板列会被歧视呢？

Question

我用gridview分页显示了一些数据，第一页正常，模板列里也正常，但是一点点击“下一页”，这些模板列里的内容就没有了，只留个这列的标题在那里！如何解决呢？？？各位大人！

Answer 1

protected void BTPageIndexChange_Click(object sender, EventArgs e)
    {
        string Arg = ((LinkButton)sender).CommandArgument;        switch (Arg)
        {
            case "First":
                this.GridView1.PageIndex = 0;
                break;
            case "Next":
                if (this.GridView1.PageIndex < this.GridView1.PageCount - 1)
                    this.GridView1.PageIndex += 1;
                break;
            case "Prev":
                if (this.GridView1.PageIndex > 0)
                    this.GridView1.PageIndex -= 1;
                break;
            case "Last":
                if (this.GridView1.PageCount > 1)
                {
                    this.GridView1.PageIndex = this.GridView1.PageCount - 1;
                }
                break;
        }        BindData();
    }

Answer 2

重新绑定BindData()这个有问题吗？注释掉或者贴出来看看。

public void BindData()
    {
        try
        {
            Session["Column"] += "机票明细";
           
            if (!CheckRight("07003", "07", false))
            {
                Session["Column"] = Session["Column"].ToString().Replace("佣金(元)", "");
                Session["Column"] = Session["Column"].ToString().Replace("佣金比率", "");
            }
            if (!CheckRight("07004", "07", false))
            {
                Session["Column"] = Session["Column"].ToString().Replace("毛利(元)", "");
            }            Session["Column"] += "充值";
            for (int i = this.GridView1.Columns.Count - 1; i > -1; i--)
            {
                if (Session["Column"] != null && !Session["Column"].ToString().Contains(this.GridView1.Columns[i].HeaderText))
                {
                    this.GridView1.Columns.Remove(this.GridView1.Columns[i]);
                }
            }            if (Session["sql"] != null)
            {
                //string temp = Session["Group"].ToString();
                DataTable dt = Query.ProcessSql(Session["sql"].ToString(), "MYAMS20");
                //dt.DefaultView.Sort =ViewState["SortExpression"].ToString()+" "+ViewState["SortDirection"].ToString();
                
                this.GridView1.DataSource = dt;
                this.GridView1.DataBind();                this.LBCurPage.Text = (this.GridView1.PageIndex + 1).ToString();
                this.LBTotalPage.Text = this.GridView1.PageCount.ToString();
                this.LBCurRecord.Text = (this.GridView1.PageIndex * this.GridView1.PageSize + 1).ToString();
                this.LBTotalRecord.Text = (this.GridView1.PageSize * this.GridView1.PageIndex + this.GridView1.Rows.Count).ToString();                if (dt.Rows.Count < 1)
                {
                    this.LBTip.Text = "查询结果为空！";
                }
            }
        }
        catch {
            this.LBTip.Text = "查询结果为空！";
        }
    }

Answer 4

楼主,你在Session里放的东西太多了吧?

Answer 5

你跟一下，Session["sql"] 是不是为空？dt是不是还有值？

Answer 6

是不是这样
         case "Next":
                if (this.GridView1.PageIndex < this.GridView1.PageCount - 1)                    this.GridView1.CurrentPageIndex +=1                break;

Answer 7

将你的数据 绑定 写到
if(!IsPostBack)
{
//里面试试
}
