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:

C#


    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();


            }


        }


    }




VB.NET


    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.
