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" %>

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

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

<td>

<asp:TextBox ID="TextBox4" runat="server"></asp:TextBox>

<tr>

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

<asp:Button ID="Button1" runat="server" Text="Update Data" OnClick="Button1_Click"

BackColor="Orange" Font-Bold="true" /><br />

<br />

</td>

<br />

<br />

<table>

<tr>

<td colspan="3">

<asp:Label ID="Label5" runat="server" Font-Bold="true"></asp:Label>

</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:

Step 6: The data updated output of the application looks like this:
