Question

我正在尝试使用repeater Control

插入评论

我在html中的代码

 <asp:Repeater ID="repConcerns" runat="server" OnItemCommand="post"  >
           <ItemTemplate >           
             <div class="row col-md-12">


                         <div class="col-sm-2" style="background-color:#808080">
                         <asp:Image ID="Image1" runat="server" ImageUrl='<%#Eval("Pathh") %>' width="90px" Height="90px" CssClass="img-circle" title='<%#Eval("Name") %>'/>&nbsp;<br/><asp:LinkButton ID="LinkButton1" runat="server" Text='<%#Eval("Name") %>'  CssClass="btn btn-info btn-sm" CommandName="btnMessage" CommandArgument='<%#Eval("Username") %>'></asp:LinkButton><br/>                    

                              </div> 
                       <div class="col-sm-10" style="background-color:#808080" >
                         <asp:Label ID="Label1" width="100%" style="padding:7px;" runat="server" Enabled="false" Text='<%#Eval("Title") %>'> </asp:Label>
                         <asp:TextBox ID="txtMessage" placeholder="Empty Post" width="100%" style="padding:7px;" runat="server" Text='<%#Eval("Detail") %>' TextMode="MultiLine" Enabled="false" Height="100px"> </asp:TextBox>
                         <asp:HiddenField ID="HiddenField1" runat="server" Value='<%#Eval("Sno") %>' />
                        <div class="bar"></div> 

                           <asp:TextBox ID="txtcomment" runat="server" CssClass="form-control form-control-sm" placeholder="Comment / Write Openion Suggestion" TextMode="MultiLine" Height="40px"></asp:TextBox>
                           <asp:LinkButton ID="btn" runat="server"  CssClass="btn btn-primary" CommandName="comment" CommandArgument='<%#Eval("Sno") %>' >Post</asp:LinkButton>
                       </div>



              </div> 
               <div  style="padding-bottom:10px;"></div>

                 <%--<br /> --%>                     
           </ItemTemplate>
        </asp:Repeater>

和C＃代码

 protected void post(object source, RepeaterCommandEventArgs e)
{

    if(e.CommandName== "comment")
    {
        a = e.CommandArgument.ToString();

        SqlConnection con = new SqlConnection(strconn);
        SqlCommand com = new SqlCommand();
        com.CommandText = "insert into Comments(Sno,Comment,Username)values('" +a+ "','" + txtcomment.Text  + "','" + username + "')";
        con.Open();


    }
}

我不知道如何插入表格＃34;评论＆＃34;。我做了一个＆＃34; Page＆＃34;他们是墙上的帖子。我已经为评论添加了一个选项。每个帖子都会显示评论按钮。但我不知道如何在表格中插入评论＆＃34;评论＆＃34;。我试图插入评论与相应的＆＃34; Sno＆＃34;保存在HiddenField中的帖子。但是当我尝试在那里写文本框id时，＃34; txtcomment.text＆＃34;它给了我错误。我如何插入。

我已对你的原始代码做了一些修改 - 注意评论：

protected void post(object source, RepeaterCommandEventArgs e)
{

    if(e.CommandName== "comment")
    {
        //Find TextBox Control
        TextBox txt = (TextBox)e.Item.FindControl("txtcomment");
        var sno = e.CommandArgument.ToString();

        SqlConnection con = new SqlConnection(strconn);
        SqlCommand com = new SqlCommand();
        com.CommandText = "INSERT INTO Comments(Sno,Comment,Username) VALUES (@SNO, @COMMENT, @USERNAME)";
        com.Connection = con;

        //Add Command Parameters
        com.Parameters.AddWithValue("@SNO", sno);
        com.Parameters.AddWithValue("@COMMENT", txt.Text);
        com.Parameters.AddWithValue("@USERNAME", username);

        con.Open();

        //Execute Command
        com.ExecuteNonQuery();
    }
}

中继器控制，插入
