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.
 
This response doesn't have anything to do with what your question was about,
but i feel that the issue must be addressed. I see below from your code
example that you're starting to build build dynamic sql statements within
your application.

Before you continue any further, you should read this article on SQL
injection:
http://msdn.microsoft.com/en-us/library/ms161953.aspx

You should avoid using dynamic sql statements like you would avoid getting
the black plague. Parameterized statements are a much better approach and
much more secure than simply concatenating strings together. You're exposing
your application to all sorts of problems doing what you're doing below. As
for your problem, the error tells you what the problem is - and if you read
the stack trace it will more than likely tell you the exact line that is
causing the problem.

That error means you're trying to use something that the application doesn't
want. If the application expects a value from 0 to 2, and you pass in a 4
that's the exception that will get thrown. Look at the stack trace or post
more information about the error if you want a more definitive answer. The
amount of information you've given us isn't enough to give you a specific
answer to fix your problem.
