AllowPaging not working

[Guest]

I have a datagrid that I set the PageSize = 10 and AllowPaging = True,
however when I display the page in my browser, it shows 10 rows and the
paging arrows but does not page when I click the "Next" hyperlink. Does
anyone know of a problem with this feature?

You have to manually handle the event for this, and rebind the data. From
what I recall, you don't get this completely for free.

Do you know where I can find the OnPageIndexChanged event handler on the
datagrid? There does not seem to be a property setting on the property
window for the datagrid. Do you have an example of a subroutine that does
paging?

This code does not seem to work:

Private Sub DataGrid1_SelectedIndexChanged(ByVal sender As Object, ByVal e
As DataGridPageChangedEventArgs)
DataGrid1.CurrentPageIndex = e.NewPageIndex
DataGrid1.DataBind()
End Sub

Simple VB code. -Shaw

Private Sub dgd_PageIndexChanged(ByVal source As Object, ByVal e As
System.Web.UI.WebControls.DataGridPageChangedEventArgs) Handles
dgd.PageIndexChanged
'Change pages on the grid.
dgd.CurrentPageIndex = e.NewPageIndex

Dim dtView As DataView = CType(Cache("MyDataView"), DataView)
If Not (dtView Is Nothing) Then
dgd.DataSource = dtView
dgd.DataBind()
End If
End Sub

Thank you for the code but I still can't get it to work. Your code contains
the syntax: CType(Cache("MyDataView"), DataView) What would I put in the
"MyDataView" portion of this statement? My datagrid is name "DataGrid1" and
I am assuming this is not what you mean.

He is getting the DataView, because that is the datasource for the grid. You
need to get whatever you are using as the datasource, and rebind it to the
grid.

If you are storing your data in cache or session in between requests, then
you need to get it from there. If you aren't storing it anywhere, you need
to requery the database, and then rebind the data.

Thank you Marina!, it worked perfectly after your explanation.
