questions is how do i allow paging on this. thank you in advance.

Hello,

I'v seen this question 3 times this month. Check the following article

Adding Paging Support to the Repeater or DataList with the PagedDataSource Class

Regards 

this article is using sqladapter how do i do mine without the sqladapter? im calling files from a directory folder

 Hello,

No, it is not using that and this is the best way of doing paging.

Regards

ok so i finally got it to this. but when i click next it doesn't to to next page or even when click previous nothing happen. the pictures showed up on the repeater but it just doesn't go to the next page. please help me

Imports System.IO

Inherits System.Web.UI.Page

If Not Page.IsPostBack Then

'ViewState("Start") = 0

End If

End Sub

Dim objDI As New IO.DirectoryInfo("C:\TestingAjaxSite\images\")

objPds.AllowPaging = True

If objPds.IsFirstPage Then

Me.cmdNext.Enabled = True

ElseIf objPds.IsLastPage = True Then

Me.cmdPrev.Enabled = True

Else

Me.cmdPrev.Enabled = True

Me.cmdNext.Enabled = True

End If

End Sub

Dim PageNumber As Integer

Public Function currentpage() As Integer

Dim obj As New Object

If obj Is DBNull.Value Then

Else

End If

End Sub

End Class

You have to save page numbers inside a viewstate not variable as you did because it will be lost after postback. In both buttons events handlers use this

'Button next
ViewState("_CurrentPage") = CInt(ViewState("_CurrentPage")) + 1

/Button previous
ViewState("_CurrentPage") = CInt(ViewState("_CurrentPage")) - 1

Regards 

thank you that helped. but now the page keep doing post back is there a way i could apply ajax or something else to make it not post back?

Yes sure, a faster wayto do that is to place everything inside the updatepanel. 

thank you you are so helpful. appreciate alot.

so now that is working. the next step is when i click on item1 from repeater, it will display that item on the slideshow and continue on to the next item. i might have question with that later. is it ok to ask you?

i originally have

<img src='<%# DataBinder.Eval(Container.DataItem, "FullName") %>' height="50" width="50" />

and this works fine but when i change it to asp:image like the line below, it doesn't display the image . the reason why i want to do that is because i want to be able to click on the image so that i could pass the the value to the slideshow to display that item on the repeater.

<asp:image runat="server" ID="text"  imageurl='<%# DataBinder.Eval(Container.DataItem, "FullName") %>' height="50" width="50" />

i got it

<asp:ImageButton ID="ImageButton1" runat="server" ImageUrl='<%# "~/images/" & DataBinder.Eval(Container.DataItem, "Name")%>' Width="50" Height="50" />

Sorry i was away when you posted the request above. Anyway, i'm glad to see that working for you.

Let me know if you need further help.

Regards
 

i do actually

i have this code here that display image in a repeater and now what i want to do is when i click on it i want it to pass me the picture name or something like that. so what value do i need to do here to achieve that?

<asp:Repeater ID="dlImages" runat="server">
                            <ItemTemplate>
                               <asp:ImageButton ID="ImageButton1" runat="server"
                                    ImageUrl='<%# "~/images/" & DataBinder.Eval(Container.DataItem, "Name")%>' Width="50" Height="50" />
                            </ItemTemplate>
                    </asp:Repeater>

Protected Sub dlImages_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.RepeaterCommandEventArgs) Handles dlImages.ItemCommand
        what should be in here and what other attributes do i need for the imagebutton?
    End Sub

please help me. thanks

 Yes, this can be done easily

HTML
 

<asp:ImageButton ID="ImageButton1" runat="server"
ImageUrl='<%# "~/images/" & DataBinder.Eval(Container.DataItem, "Name")%>'
Width="50" Height="50" CommandName="ShowMe" 
CommandArgument='<%#DataBinder.Eval(Container.DataItem, "Name")%>' />

Code Behind

Protected Sub dlImages_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.RepeaterCommandEventArgs) Handles dlImages.ItemCommand
If e.CommandName.ToString() = "ShowMe" Then

' do something
Response.Write(e.CommandArgument.ToString())


End If
End Sub
