 Note: EMP_ID column is set to Primary key and Identity specification is set to yes with Identity increment and Identity seed equal to 1. Insert some data in this table that you  want to show in the Gridview.
  • Create a stored procedure in sql server as:
CREATE PROCEDURE GET_EMP_DATA                       
AS
BEGIN               
                SELECT * FROM EMPLOYEE                
END
  • Now in web.config file add the connectionstring under <configuration> tag :
<connectionStrings>
    <add name="EmpCon" connectionString="Data Source=LALIT;Initial Catalog=MyDataBase;Integrated Security=True"/>
  </connectionStrings>

  • Add a GridView control in design page of your asp.net website under <BODY> tag
<fieldset style="width:230px;">
            <legend>Gridview Binding Example</legend>
            <asp:GridView ID="EmpGridView" runat="server" AutoGenerateColumns="False" CellPadding="4" ForeColor="#333333" GridLines="None">    
         <AlternatingRowStyle BackColor="White" />
       <Columns>  
        <asp:BoundField DataField="EMP_NAME"  HeaderText="Name" />
        <asp:BoundField DataField="DEPT"  HeaderText="Department" />
        <asp:BoundField DataField="SALARY"  HeaderText="Salary" />  
      </Columns>
         <EditRowStyle BackColor="#2461BF" />
         <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
         <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
         <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
         <RowStyle BackColor="#EFF3FB" />
         <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
         <SortedAscendingCellStyle BackColor="#F5F7FB" />
         <SortedAscendingHeaderStyle BackColor="#6D95E1" />
         <SortedDescendingCellStyle BackColor="#E9EBEF" />
         <SortedDescendingHeaderStyle BackColor="#4870BE" />
 </asp:GridView>
