How To Update a Grid View Value Using Procedure in ASP .NET
Step 1: First creating a Stored Procedure using SQL Server. Procedure name as empDetails
CREATE PROCEDURE empDetails @name nchar(10), @id nchar(10), @emp_age nchar(10)
AS
BEGIN
UPDATE emp_tbl SETnme = @name,
age = @emp_age
WHERE emp_id = @Id
END
AS
BEGIN
UPDATE emp_tbl SETnme = @name,
age = @emp_age
WHERE emp_id = @Id
END
Step 2. Design the page. Take a Grid View Control to show data and three textboxes and a button.
<%@ Page Language="C#" AutoEventWireup="true"
Codevirtual="Default.aspx.cs" Inherits="_Default" %>
<%@ Register assembly="AjaxControlToolkit"
namespace="AjaxControlToolkit" tagprefix="cc1" %>

<asp:BoundField DataField="emp_id" HeaderText="Employe ID" />
</Columns><HeaderStyle BackColor="#CCCCCC" BorderStyle="Inset" BorderWidth="2px" />
</asp:GridView> </div>
<br /><br /> <table>
<tr><td>Enter ID(From Grid View):</td><td>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox></td></tr>
<tr><td>Enter Name:</td><td>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox></td></tr>
<tr><td>Enter Age:</td><td>
<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox></td></tr>
<tr><td>
<asp:Button ID="Button1" runat="server" Text="Update" onclick="Button1_Click" />
]</td></tr>
</table>
</form>
</body>

public void update_value(string emp_name, string Id, string emp_age)
{

SqlCommand cmd = new SqlCommand("empDetails",newConnection);
cmd.CommandType = CommandType.StoredProcedure; //Procedure
cmd.Parameters.AddWithValue("@name", emp_name);
cmd.Parameters.AddWithValue("@id", Id);
cmd.Parameters.AddWithValue("@emp_age", emp_age);
cmd.ExecuteNonQuery();
newConnection.Close();
}
protected void Button1_Click(object sender, EventArgs e)
{ //call the function to updating the grid view
update_value(TextBox2.Text,TextBox1.Text,TextBox3.Text);
}
}
