Simple way to do the Paging in gridview

In aspx page:


 <form id="form1" runat="server">
    <div>
        <asp:GridView ID="GridView1" runat="server" AllowPaging="true" PagerSettings-Mode="Numeric" PagerSettings-Position="TopAndBottom" PageSize="10" OnPageIndexChanging="GridView1_PageIndexChanging" >
       
        </asp:GridView>
    </div>
    </form>

In code behind:


protected void Page_Load(object sender, EventArgs e)
    {


        adddata();
    }


//Binding gridview


    public void adddata()
    {


        conn.Open();

        string strSQL = "Select * from LOGINDETAILS";

        OleDbCommand cmd = new OleDbCommand(strSQL, conn);

        DataSet ds = new DataSet();

        OleDbDataAdapter da = new OleDbDataAdapter(cmd);

        da.Fill(ds);

        GridView1.DataSource = ds;

        GridView1.DataBind();
        conn.Close();

    }


//paging index


    protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)          
    {
        GridView1.PageIndex = e.NewPageIndex;
        adddata();
    }

output:
