Introduction

Today, in this article let's play around with one of the interesting and most useful concepts in C#.

Question: What is Update Data with Stored Proc using XSD (Typed Dataset)?

In simple terms "It provides the flexibility to update data with a Stored Procedure using a dataset".

Step 1: Create a new WebForm project:

Step 2: The employee dataset looks like this:

Step 3: The complete code of WebForm1.aspx looks like this:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="SPUpdateXSDApp.WebForm1" %>

<body>

    <form id="form1" runat="server">

    <div>

        <center>

            <table>

                <tr>

                    <td>

                        <asp:Label ID="Label1" runat="server" Text="Update with Stored Proc using XSD" Font-Bold="true"></asp:Label>

                    </td>

                </tr>

                <tr>

                    <td align="center" colspan="2">

                            <SortedDescendingHeaderStyle BackColor="#383838" />

                        </asp:GridView>

                    </td>

                </tr>

            </table>

            <br />

            <br />

            <table>

                <tr>

                    <td>

                        <asp:Label ID="Label6" runat="server" Text="Please Enter Id: " ForeColor="Brown"

                            Font-Bold="true" Font-Italic="true"></asp:Label>

                </tr>

                <tr>

                </tr>

                <tr>

                    <td>

                </tr>

                <tr>

                    <td colspan="2" align="center">

                    </td>

                </tr>

            </table>

        </center>

    </div>

    </form>

</body>

</html>

Step 4: The complete code of WebForm1.aspx.cs looks like this:
 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using SPUpdateXSDApp.EmployeeDSTableAdapters;namespace SPUpdateXSDApp

{

    public partial class WebForm1 : System.Web.UI.Page

    {

        protected void Page_Load(object sender, EventArgs e){TextBox4.Focus();

        }

        protected void Button1_Click(object sender, EventArgs e)

        {

            if (string.IsNullOrEmpty(TextBox4.Text) || string.IsNullOrEmpty(TextBox1.Text) || string.IsNullOrEmpty(TextBox2.Text) || string.IsNullOrEmpty(TextBox3.Text))

            {

                Label5.Text = "Please Enter Some Values";Label5.ForeColor = System.Drawing.Color.Red;

            }

            else

            {

                objQueryAdapter.UpdateData(int.Parse(TextBox4.Text), TextBox1.Text, TextBox2.Text, int.Parse(TextBox3.Text));

                EmployeeDS.SelectDataDataTable objEmployeeTable = objAdapter.GetData();

                var query = from r in objEmployeeTable select new

                {

                    FirstName = r.FirstName, LastName = r.LastName, Age = r.Age

                }

                ;

                GridView1.DataSource = query;GridView1.DataBind();

                Label5.Text = "Records Updated Successfully";

                Label5.ForeColor = System.Drawing.Color.Green;

                TextBox4.Text = string.Empty;

                TextBox1.Text = string.Empty;

                TextBox2.Text = string.Empty;

                TextBox3.Text = string.Empty;

            }

        }

        #region Instance MembersQueriesTableAdapter objQueryAdapter = new QueriesTableAdapter();

        EmployeeDSTableAdapters.SelectDataTableAdapter objAdapter = new EmployeeDSTableAdapters.SelectDataTableAdapter();

        #endregion

    }

}
 

Step 5: The output of the application looks like this:
