ASP.Net C＃其中ID等于Cell

Question

大家好，我有这样的发言：

cmd = new SqlCommand("UPDATE Comments SET Flagged = '" + "Yes" + "' WHERE Comment_ID ='" + Row.Cells[0] + "'", con);

Visual Studio强调Row.Cells [0]在当前上下文中不存在Row。

你能看一看，看看我哪里出错。

完整方法代码：

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {

       GridView1.RowCommand += new GridViewCommandEventHandler(GridView1_RowCommand);
        if (e.CommandName == "cmdFlag")
        {
        con.Open();

        cmd = new SqlCommand("UPDATE Comments SET Flagged = '" + "Yes" + "' WHERE Comment_ID ='" + Row.Cells[0] + "'", con);

        cmd.ExecuteNonQuery();

        Response.Redirect("~/renteronly/flagset.aspx");
        }
}

Answer 1

Mark，您需要将 CommandArgument 属性绑定到 Comment_ID 。

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
    if (e.CommandName == "cmdFlag")
      {
        con.Open();
        cmd = new SqlCommand("UPDATE Comments SET Flagged = 'Yes' WHERE Comment_ID = @Comment_ID", con);
        cmd.Parameters.AddWithValue("@Comment_ID",e.CommandArgument);
        cmd.ExecuteNonQuery();
        Response.Redirect("~/renteronly/flagset.aspx");
      }
   }

Answer 2

您可以像GridView.SelectedRow一样获取所选行。
