Step 1
To Create the comment box, we need to add some tables and stored procedures.
Create a UserTable:
- CREATE TABLE [dbo].[UserTable](
- [UserName] [varchar](50) NOT NULL,
- [Password] [varchar](50) NULL,
- CONSTRAINT [PK_UserTable] PRIMARY KEY CLUSTERED
- (
- [UserName] ASC
- )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
- ) ON [PRIMARY]
-
- GO
Create a ParentComment Table:
- CREATE TABLE [dbo].[ParentComment](
- [CommentID] [int] IDENTITY(1,1) NOT NULL,
- [UserName] [varchar](50) NULL,
- [CommentMessage] [varchar](300) NULL,
- [CommentDate] [date] NULL,
- CONSTRAINT [PK_ParentComment] PRIMARY KEY CLUSTERED
- (
- [CommentID] ASC
- )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
- ) ON [PRIMARY]
-
- GO
-
- SET ANSI_PADDING OFF
- GO
-
- ALTER TABLE [dbo].[ParentComment] WITH CHECK ADD CONSTRAINT [FK_ParentComment_UserTable] FOREIGN KEY([UserName])
- REFERENCES [dbo].[UserTable] ([UserName])
- GO
-
- ALTER TABLE [dbo].[ParentComment] CHECK CONSTRAINT [FK_ParentComment_UserTable]
- GO
Create a ChildComment Table:
- CREATE TABLE [dbo].[ChildComment](
- [CommentID] [int] IDENTITY(1,1) NOT NULL,
- [UserName] [varchar](50) NULL,
- [CommentMessage] [varchar](300) NULL,
- [CommentDate] [date] NULL,
- [ParebCommentID] [int] NULL,
- CONSTRAINT [PK_ChildComment] PRIMARY KEY CLUSTERED
- (
- [CommentID] ASC
- )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
- ) ON [PRIMARY]
-
- GO
-
- SET ANSI_PADDING OFF
- GO
-
- ALTER TABLE [dbo].[ChildComment] WITH CHECK ADD CONSTRAINT [FK_ChildComment_ParentComment] FOREIGN KEY([UserName])
- REFERENCES [dbo].[UserTable] ([UserName])
- GO
-
- ALTER TABLE [dbo].[ChildComment] CHECK CONSTRAINT [FK_ChildComment_ParentComment]
- GO
-
- ALTER TABLE [dbo].[ChildComment] WITH CHECK ADD CONSTRAINT [FK_ChildCommentID_ChildCommentID] FOREIGN KEY([ParebCommentID])
- REFERENCES [dbo].[ParentComment] ([CommentID])
- GO
-
- ALTER TABLE [dbo].[ChildComment] CHECK CONSTRAINT [FK_ChildCommentID_ChildCommentID]
- GO
Step 2
Create a stored procedure for comments session so as to check credentials of the User.
- create proc spCheckUserCredentials
- (@UserName varchar(25))
- as
- Begin
- Select *from UserTable where UserName=@UserName
- End
Insert comment for ParentComment.
- create proc spCommentInsert
- (@UserName varchar(25),
- @CommanetMessage varchar(300))
- as
- Begin
- Insert into ParentComment(UserName,CommentMessage,CommentDate)values(@UserName,@CommanetMessage,GETDATE())
- End
Insert reply comment for ChildComment.
- create proc spCommentReplyInsert(@UserName varchar(25),
- @CommentMessage varchar(300),
- @ParentCommentID int)
- as
- Begin
- Insert into ChildComment(UserName,CommentMessage,CommentDate,ParebCommentID)
- values(@UserName,@CommentMessage,GETDATE(),@ParentCommentID)
- End
Get Data Comment from database.
- create Proc spGetParetComment
- as
- Begin
- Select *from ParentComment
- End
- create proc spGetParentCommentByParentCommnetID(@ParentCommnetID int)
- as
- Begin
- select *from ChildComment where ParebCommentID=@ParentCommnetID
- End
Step 3
Create a webform for UserLogin.
- <body>
- <form id="form1" runat="server">
- <div>
-
- <table class="auto-style1">
- <tr>
- <td class="auto-style2">Login Page</td>
- <td> </td>
- </tr>
- <tr>
- <td class="auto-style2">UserName</td>
- <td>
- <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
- </td>
- </tr>
- <tr>
- <td class="auto-style2">Password</td>
- <td>
- <asp:TextBox ID="TextBox1" TextMode="Password" runat="server"></asp:TextBox>
- </td>
- </tr>
- <tr>
- <td class="auto-style2">
- <asp:Button ID="Button1" runat="server" Height="31px" Text="LOGIN" Width="115px" OnClick="Button1_Click" />
- </td>
- <td> </td>
- </tr>
- </table>
- <asp:Label ID="Label1" runat="server" ></asp:Label>
- <asp:LinkButton runat="server" ID="lnkRegistor" Text="Registration" PostBackUrl="~/Default3.aspx"></asp:LinkButton>
- </div>
- </form>
- </body>

Parent Comment is a message in the comment box
Reply to a parent comment with a child comment.
