I have bound a datapager control to a listview.
I would like to scroll to the first item of the listview control on the DataPager click. I think this should be done with javascript. It seems that the datapager does not a开发者_高级运维llow that.
What options do I have? How can I scroll to a specific anchor when clicking on the DataPager?
you can use the basic html named anchor to scroll to a specific anchor.
You can use the javascript function scrollIntoView for that on client side or on "server side": http://www.codeproject.com/KB/aspnet/ViewControl.aspx
Thanks Tim!
And for the lazy guys out there (just like me ;), here is the VB.NET equivalent. It contains typo corrections and the new RegisterClientScriptBlock Method
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
FocusControlOnPageLoad("Label1", Me.Page)
End Sub
Public Sub FocusControlOnPageLoad(ByVal ClientID As String, ByVal page As System.Web.UI.Page)
Dim csName As String = "ScrollViewScript"
Dim csType As Type = Me.GetType
Dim cs As ClientScriptManager = page.ClientScript
If Not cs.IsClientScriptBlockRegistered(csType, csName) Then
Dim csText As New StringBuilder()
csText.Append("<script>function ScrollView(){")
csText.Append("var el = document.getElementById('" & ClientID & "');")
csText.Append("if (el != null){")
csText.Append("el.scrollIntoView();")
csText.Append("el.focus();}}")
csText.Append("window.onload = ScrollView;")
csText.Append("</script>")
cs.RegisterClientScriptBlock(csType, csName, csText.ToString())
End If
End Sub
