hi, i'm having problems with a datagrid paging.
it's populates fine, but when i click the paging button appears this
error:"Specified argument was out of the range of valid
values.Parameter name: index"

I paste the code here in case someone can help me.

Sub paginaNueva(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.DataGridPageChangedEventArgs)
       DataGrid1.CurrentPageIndex = e.NewPageIndex
       binddata()
   End Sub

Sub binddata()
       Dim myConnection As New
System.Data.SqlClient.SqlConnection("myconnection_string")
       Dim strSQL As String = "SELECT * FROM
SISTEMAS_SIOPELMEETING_FOTOS WHERE titulo LIKE '%'+'almuerzos'+'%'"
       Dim strSQL2 As String = "SELECT * FROM
SISTEMAS_SIOPELMEETING_FOTOS WHERE titulo LIKE
'%'+'presentaciones'+'%'"
       Dim strSQL3 As String = "SELECT * FROM
SISTEMAS_SIOPELMEETING_FOTOS WHERE titulo LIKE '%'+'hotel'+'%'"
       Dim strSQL4 As String = "SELECT * FROM
SISTEMAS_SIOPELMEETING_FOTOS WHERE titulo LIKE '%'+'estancia'+'%'"
       Dim myCommand As New System.Data.SqlClient.SqlCommand(strSQL,
myConnection)
       Dim myCommand2 As New
System.Data.SqlClient.SqlCommand(strSQL2, myConnection)
       Dim myCommand3 As New
System.Data.SqlClient.SqlCommand(strSQL3, myConnection)
       Dim myCommand4 As New
System.Data.SqlClient.SqlCommand(strSQL4, myConnection)
       Dim myAdapter As New
System.Data.SqlClient.SqlDataAdapter(myCommand)
       Dim myAdapter2 As New
System.Data.SqlClient.SqlDataAdapter(myCommand2)
       Dim myAdapter3 As New
System.Data.SqlClient.SqlDataAdapter(myCommand3)
       Dim myAdapter4 As New
System.Data.SqlClient.SqlDataAdapter(myCommand4)
       Dim ds As New System.Data.DataSet()
       Dim ds2 As New System.Data.DataSet()
       Dim ds3 As New System.Data.DataSet()
       Dim ds4 As New System.Data.DataSet()
       myAdapter.Fill(ds)
       myAdapter2.Fill(ds2)
       myAdapter3.Fill(ds3)
       myAdapter4.Fill(ds4)
       DataGrid1.DataSource = ds
       Datagrid2.DataSource = ds2
       Datagrid3.DataSource = ds3
       Datagrid4.DataSource = ds4
       DataGrid1.DataBind()
       Datagrid2.DataBind()
       Datagrid3.DataBind()
       Datagrid4.DataBind()
       myConnection.Close()
   End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Load
       If Not Page.IsPostBack Then
           binddata()
       End If
   End Sub

Thanks.
