怎么老提示字符格式有问题呢？

Question

protected void LinkButtonUpdate_Click(object sender, EventArgs e)
    {
        int nCount = GridView1.Rows.Count;
        int nSelectNum = 0;
        for (int i = 0; i < nCount; i++)
        {
            CheckBox CheckBox1 = GridView1.Rows[i].Cells[0].FindControl("CheckBox1") as CheckBox;
            if (CheckBox1.Checked)
            {
                nSelectNum++;
            }
        }
        if (nSelectNum > 1)
        {
            Response.Write("<script>alert('不能选择多个记录进行修改!')</script>");
        }
        else
        {
            nCount = GridView1.Rows.Count;
            for (int i = 0; i < nCount; i++)
            {
                CheckBox CheckBox1 = GridView1.Rows[i].Cells[0].FindControl("CheckBox1") as CheckBox;
                if (CheckBox1.Checked)
                {
                    int bianhaoID = Convert.ToInt32(GridView1.Rows[i].Cells[1].Text);
                    Response.Redirect("update.aspx?BHID="+bianhaoID);
                }
            }
        }    }

Answer 1

Response.Redirect("update.aspx?BHID="+bianhaoID); 
//
Response.Redirect("update.aspx?BHID="+bianhaoID.ToString());

Answer 2

LZ。
 int bianhaoID = Convert.ToInt32(GridView1.Rows[i].Cells[1].Text); 
                    Response.Redirect("update.aspx?BHID="+bianhaoID); 你不感觉你自己做画蛇添足吗？

Answer 3

GridView1.Rows[i].Cells[1].Text
格式不对嘛
这段代码太多多余的地方了

Answer 4

int bianhaoID = Convert.ToInt32(GridView1.Rows[i].Cells[1].Text);

Answer 5

int bianhaoID = Convert.ToInt32((GridView1.Rows[i].Cells[1].Controls[0] as TextBox).Text);

Answer 6

string url=String.Formatupdate.aspx?BHID={0}", bianhaoID);
Response.Redirect(url); 你看一下这种写法可以吗
要学会自己调试发现问题,然后解决.

Answer 7

            int nCount = GridView1.Rows.Count;
            int nSelectNum = 0,index = -1;
            for (int i = 0; i < nCount; i++)
            {
                if ((GridView1.Rows[i].Cells[0].FindControl("CheckBox1") as CheckBox).Checked)
                {
                    nSelectNum++;
                    if (nSelectNum > 1)
                    {
                        Response.Write(" <script>alert('不能选择多个记录进行修改!') </script>");
                        return;
                    }
                    index = i;
                }
            }
            if (index != -1)
            {
                Response.Redirect("update.aspx?BHID=" + GridView1.Rows[i].Cells[1].Text);
            }

Answer 8

            int nCount = GridView1.Rows.Count;
            int nSelectNum = 0, index = -1;
            for (int i = 0; i < nCount; i++)
            {
                if ((GridView1.Rows[i].Cells[0].FindControl("CheckBox1") as CheckBox).Checked)
                {
                    nSelectNum++;
                    if (nSelectNum > 1)
                    {
                        Response.Write(" <script>alert('不能选择多个记录进行修改!') </script>");
                        return;
                    }
                    index = i;
                }
            }
            if (index != -1)
            {
                Response.Redirect("update.aspx?BHID=" + GridView1.Rows[index].Cells[1].Text);
            }
