Question

如何查找一个Panel中的一个GridView中的ItemTemplate项中某一个控件(如:Label)的值？

Answer 1

 Label lbl= ((Label )GridView.Rows[e.RowIndex].FindControl("Label")).Text;

Answer 2

错误 47 “System.Web.UI.ImageClickEventArgs”不包含“RowIndex”的定义，并且找不到可接受类型为“System.Web.UI.ImageClickEventArgs”的第一个参数的扩展方法“RowIndex”(是否缺少 using 指令或程序集引用?) E:\ProgramCode\OnlineTest\OnlineTestWeb\HouAdmin\PaperSet.aspx.cs 92 102 E:\...\OnlineTestWeb\
这是怎么回事？

    //将生产试卷保存到数据库    protected void imgBtnSave_Click(object sender, ImageClickEventArgs e)
    {
        string insertpaper = "insert into Taoti(LessonID,Name,JoinTime) values(" + int.Parse(ddlCourse.SelectedValue) + ",'" + txtPaperName.Text + "','" + DateTime.Now + "');SELECT @@IDENTITY as id";        int afterID = TaoTiManager.GetIDInsert(insertpaper);//保存试卷，并返回自动生成的试卷编号        if (afterID > 0)
        {            foreach (GridViewRow dr in GridView1.Rows)//保存试卷单选题信息

    }搞定了。呵呵。。

先找Panel里的Gridview 然后在遍历
