hi friend.......

frist you have to make gridView in the aspx page like this
there are two ways of Gridview for the getting the Data:

(1)only true the property of gridView for the column which is AutoGenerateColumns

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="True"
            style="margin-top: 0px" Width="529px">
        </asp:GridView>

(2)make Column inyour way like this but set the AutoGenerateColumns="False"...

<asp:GridView ID="Gridview1" runat="server" AutoGenerateColumns="False" Style="margin-top: 0px"
    Width="529px" EmptyDataText="No data availble..">
    <Columns>
        <asp:BoundField DataField="EmpName" HeaderText="Employee Name" ReadOnly="true" />
        <asp:BoundField DataField="DepartmentName" HeaderText="Department Name" ReadOnly="true" />
        <asp:BoundField DataField="Salary" HeaderText="Salary" ReadOnly="true" />
        <asp:BoundField DataField="DeductionAmount" HeaderText="Deduction Amount" ReadOnly="true" />
        <asp:BoundField DataField="NetSalary" HeaderText="Net Salary" ReadOnly="true" />
    </Columns>
</asp:GridView>

now go in the aspx.cs page

make one method like this..

public void GetEmpDetails()
{
    try
    {
        SqlConnection con = new SqlConnection("Data Source=RUDRA-PC\\SQLEXPRESS;Initial Catalog=Testing Database;Integrated Security=True");
        con.Open();
        string strQuery = "SELECT EmpName,DepartmentName,Salary,DeductionAmount,(Salary-DeductionAmount)AS NetSalary FROM Employee INNER JOIN Department ON Employee.DepId = Department.DepId ";
        SqlCommand cmd = new SqlCommand(strQuery, con);
        SqlDataAdapter sda = new SqlDataAdapter(cmd);
        DataTable dt = new DataTable();
        sda.Fill(dt);
        Gridview1.DataSource = dt;
        Gridview1.DataBind();
        con.Close();
    }
    catch (Exception ex)
    {
        ClientScript.RegisterStartupScript(GetType(), "fnCall", "<script language='javascript'>alert('" + ex.Message.ToString() + "');</script>");
    }
}

and call this Method in the PageLoad like this

protected void Page_Load(object sender, EventArgs e)
{
    GetEmpDetails();
}

also add three namespace in the aspx.cs page...

C#

using System.Data;
using System.Data.Sql;
using System.Data.SqlClient;

Hope Fully, now you get the data in the grid view...
Best Of Luck....
