gridview点击某行获取值的问题

Question

  protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
        {
            try
            {                this.TextBox5.Text = "4";                this.TextBox4.Text = this.GridView1.Rows[e.NewSelectedIndex].Cells[2].Text.ToString();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                //鼠标移动到每项时颜色交替效果
                e.Row.Attributes["onmouseover"] = "e=this.style.backgroundColor;this.style.backgroundColor='#cccccc'";
                e.Row.Attributes["onmouseout"] = "this.style.backgroundColor=e";
                //设置悬浮鼠标指针形状为"小手"   
                e.Row.Attributes["style"] = "Cursor:hand";
                //鼠标点击某行即选中某行
                e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.GridView1, "Select$" + e.Row.RowIndex);
            }为什么我点击gridview某一行，this.TextBox4.Text获取不到值

Answer 1

GridView1.Rows[GridView1.SelectedIndex].Cells[0].Text;

Answer 2

很简单，用RowDataBound事件，将我代码中的控件换成你的就Ok了
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("onmouseover", "thiscolor = this.style.backgroundColor,this.style.backgroundColor='LightCyan'");
            e.Row.Attributes.Add("onmouseout", " this.style.backgroundColor = thiscolor");
            e.Row.Style["cursor"] = "hand";
        }        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("OnDblClick", "javascript:window.opener.document.Form1.jhbh.value='" + e.Row.Cells[0].Text.ToString().Trim() + "';" +
                "window.opener.document.Form1.Button1.click();" +
                "window.close();");
        }
    }

Answer 3

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
  {
this.TextBox4.Text = this.GridView1.Rows[e.NewSelectedIndex].Cells[2].Text.ToString();//这行应该放到这里面才对吧？？并确定cell[2]是不是你想传递值的行
  }

Answer 4

是的啊，那句写在rowdatabound肯定是错的
