Inserting New Row in GridView in Asp.net 2.0

steps:

1) Create the simple web application (asp.net with C#).

2) Create new table (User) in your database.

Column Name	Data Type
UserId	int (Pk and AutoIncrement)
UserName	varchar(50)
Address1	varchar(50)
EmailAddress	varchar(50)

3) In your application (.aspx file) put the below code. we have first true the property of gridview (ShowFooter) and put the asp control in to the FooterTemplate. put the one label for display message.Here I not implement the edit command.

  <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="UserID"
                CellPadding="4" ForeColor="#333333" GridLines="None" ShowFooter="True">
                <Columns>
                    <asp:TemplateField HeaderText="UserID" InsertVisible="False" SortExpression="UserID">
                        <ItemTemplate>
                            <asp:Label ID="lblUserID" runat="server" Text='<%# Eval("UserID") %>'></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="UserName" SortExpression="UserName">
                        <EditItemTemplate>
                            <asp:TextBox ID="txtUserName" runat="server" Text='<%# Bind("UserName") %>'></asp:TextBox>
                        </EditItemTemplate>
                        <ItemTemplate>
                            <asp:Label ID="lblUserName" runat="server" Text='<%# Eval("UserName") %>'></asp:Label>
                        </ItemTemplate>
                        <FooterTemplate>
                        <asp:TextBox ID="txtfooterUserName" runat="server"></asp:TextBox>
                        <%-- Here we Put the RequiredFieldValidator for textbox (txtfooterUserName) --%>
                        <asp:RequiredFieldValidator ID="rfvUserName" runat="server" ControlToValidate="txtfooterUserName" ErrorMessage="*"></asp:RequiredFieldValidator>
                        </FooterTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="Address1" SortExpression="Address1">
                        <EditItemTemplate>
                            <asp:TextBox ID="txtAddress1" runat="server" Text='<%# Bind("Address1") %>'></asp:TextBox>
                        </EditItemTemplate>
                        <ItemTemplate>
                            <asp:Label ID="lblAddress1" runat="server" Text='<%# Eval("Address1") %>'></asp:Label>
                        </ItemTemplate>
                        <FooterTemplate>
                        <asp:TextBox ID="txtfooterAddress1" runat="server"></asp:TextBox>
                        </FooterTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="EmailAddress" SortExpression="EmailAddress">
                        <EditItemTemplate>
                            <asp:TextBox ID="txtAddress1" runat="server" Text='<%# Bind("EmailAddress") %>'></asp:TextBox>
                        </EditItemTemplate>
                        <ItemTemplate>
                            <asp:Label ID="lblEmailAddress" runat="server" Text='<%# Eval("EmailAddress") %>'></asp:Label>
                        </ItemTemplate>
                        <FooterTemplate>
                        <asp:TextBox ID="txtfooterEmailAddress" runat="server"></asp:TextBox>
                        <asp:RequiredFieldValidator ID="rfvEmailAddress" runat="server" ControlToValidate="txtfooterEmailAddress" ErrorMessage="*"></asp:RequiredFieldValidator>
                        <asp:RegularExpressionValidator ID="revEmailAddress" runat="server" ControlToValidate="txtfooterEmailAddress" ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" 

                    ErrorMessage="Please Enter Valid Email Address" ></asp:RegularExpressionValidator>
                        </FooterTemplate>
                    </asp:TemplateField>
                    <asp:TemplateField HeaderText="EditRecord">
                        <EditItemTemplate>
                            <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="True" CommandName="Update"
                                Text="Update"></asp:LinkButton>
                            <asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" CommandName="Cancel"
                                Text="Cancel"></asp:LinkButton>
                        </EditItemTemplate>
                        <ItemTemplate>
                            <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Edit"
                                Text="Edit"></asp:LinkButton>
                        </ItemTemplate>
                        <FooterTemplate>
                        <asp:LinkButton ID="lnkInsert" runat="server" Text ="Insert" OnClick="lnkInsert_Click"></asp:LinkButton>
                        </FooterTemplate>
                    </asp:TemplateField>
                </Columns>
                <FooterStyle BackColor="Silver" Font-Bold="True" ForeColor="White" />
                <RowStyle BackColor="#EFF3FB" />
                <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
                <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
                <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
                <EditRowStyle BackColor="#2461BF" />
                <AlternatingRowStyle BackColor="White" />
            </asp:GridView>

<asp:Label ID="lblMessage" runat="server" Text ="Insert Record Successfully" Visible ="false" > </asp:Label>

4) Open Code Behind File and on the page load event put the below code.

protected void Page_Load(object sender, EventArgs e)
    {
        //check whether page is postback or not
        //if page is not postback at that time we bind the gridview
        if (!Page.IsPostBack)
        {
          //call the function BindGridView
            BindGridView();
        }
    }

    public void BindGridView()
    {
        //here write connection string
        string strsql = DBConnection.sqlstr;

        //create object for sqlconnection
        SqlConnection sqlcon = new SqlConnection(strsql);

        //here i use the query
        //create the object of sqlcommand
        SqlCommand sqlcmd = new SqlCommand("select * from [User]", sqlcon);

        //create sqldataadapter object and give the sqlcommand as parameter
        SqlDataAdapter adp = new SqlDataAdapter(sqlcmd);
        //declare the dataset
        DataSet ds = new DataSet();
        //fill dataset using fill method of SqlDataAdapter
        adp.Fill(ds);

        //bind the GridView1
        GridView1.DataSource = ds.Tables[0];

        GridView1.DataBind();
    }

   

5) On Click Event of the Insert button put the below code or directly paste below code.

protected void lnkInsert_Click(object sender, EventArgs e)
    {
        string strsql = DBConnection.sqlstr;

        //create object for sqlconnection
        SqlConnection sqlcon = new SqlConnection(strsql);

        //here i use the query
        string strQuery = "Insert into [User] (UserName,Address1,EmailAddress) values (@UserName,@Address1,@EmailAddress)";
        //create the object of sqlcommand
        SqlCommand sqlcmd = new SqlCommand(strQuery, sqlcon);
        //find the footer row for UserName And Assign the value
        sqlcmd.Parameters.Add("@UserName", SqlDbType.VarChar, 50).Value = ((TextBox)GridView1.FooterRow.FindControl("txtfooterUserName")).Text;
        sqlcmd.Parameters.Add("@Address1", SqlDbType.VarChar, 50).Value = ((TextBox)GridView1.FooterRow.FindControl("txtfooterAddress1")).Text;
        sqlcmd.Parameters.Add("@EmailAddress", SqlDbType.VarChar, 50).Value = ((TextBox)GridView1.FooterRow.FindControl("txtfooterEmailAddress")).Text;
        //open the sql connection
        sqlcon.Open();
        // Execute the Insert Command In to Database
        sqlcmd.ExecuteNonQuery();
        //close the sqlconnection
        sqlcon.Close();
        //if record successfully insert we display the message
        lblMessage.Visible = true;
        //bind grid view for latest record
        BindGridView();
    }

Check Application.
