问题描述

<asp:GridView ID="GridView1" runat="server" CellPadding="1" CellSpacing="1"  DataKeyNames="PostID"

                       AutoGenerateColumns="False" Width="98%" OnRowCommand="GridView1_RowCommand"

                       AllowPaging="True" ShowHeader="false" onrowdatabound="GridView1_RowDataBound" BackColor="White" RepeatLayout="Table" BorderColor="#B0E3FF" BorderStyle="None" BorderWidth="1px" style="margin-left: 9px; height:auto">

 <asp:Button ID="btnComnt" runat="server" OnClick="btnComnt_Click" class="btnComment" Text="Comment" />
                 <asp:HiddenField ID="HiddenField1" Value='<%#Eval("PostID") %>' runat="server" />

 </asp:GridView>

我将数据输入HiddenField。

protected void btnComnt_Click(object sender, EventArgs e)
        {
            int userid = int.Parse(Session["UnAuthentication"].ToString());
            string date = DateTime.Now.ToString();
            int privates = 0;

            TextBox txtNewComent = FindControl("txtComent") as TextBox;
            HiddenField postNo = FindControl("HiddenField1") as HiddenField;

                Post post = new Post();
                post.Comment = new Comments(int.Parse(postNo.Value), txtNewComent.Text, userid);
                dll.PostReply(post);


        }

推荐答案

foreach (GridViewRow row in GridView1.Rows)
          {

              string textBoxText = ((TextBox)row.FindControl("txtComent")).Text;

              string userId = ((HiddenField)row.FindControl("HiddenField1")).Value;




                      Post post = new Post();
                      post.Comment = new Comments(int.Parse(userId), textBoxText.ToString(), userid);
                      dll.PostReply(post);
