Loop through all the rows in all the pages of an ASP.NET GridView

One simple way to loop through all the rows in all the pages of a GridView is to access its DataSource. Shown here is the code of how to do so:


    protected void Button1_Click(object sender, EventArgs e)


        DataSourceSelectArguments dsaArgs = new DataSourceSelectArguments();

        DataView view = (DataView)SqlDataSource1.Select(dsaArgs);

        DataTable dt = view.ToTable();

        for (int i = 0; i < dt.Rows.Count; i++)


            for (int j = 0; j < dt.Columns.Count; j++)


                string s = dt.Rows[i][j].ToString();





    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)

        Dim dsaArgs As DataSourceSelectArguments = New DataSourceSelectArguments()

        Dim view As DataView = CType(SqlDataSource1.Select(dsaArgs), DataView)

        Dim dt As DataTable = view.ToTable()

        For i As Integer = 0 To dt.Rows.Count - 1

            For j As Integer = 0 To dt.Columns.Count - 1

                Dim s As String = dt.Rows(i)(j).ToString()

            Next j

        Next i

    End Sub

Note: SqlDataSource1.Select(args) will make a call to the db every time it is accessed.
