I am developing website in vb.net. I have used Listview to display products. There are couple of filters to refine search. I am showing 36 products in one page & have total 450 products in database. Problem is if I switched to page 1 to page 10 & then apply any filter from checkboxList & after applying filter it found 10 products then it shows blanks result but 10 product is there but it still on 10th page so not showing 10 products because it is on 1st page. Can any one help me how can I Rest pageIndex after applying filter? OnPagePropertiesChanged I tried to reset page Index after listview gets bind but it is not working.

What I have tried:

VB

Protected Sub OnPagePropertiesChanging(sender As Object, e As PagePropertiesChangingEventArgs)
        TryCast(products.FindControl("DataPager1"), DataPager).SetPageProperties(e.StartRowIndex, e.MaximumRows, False)
        Me.buildWhereClause()
        products.SelectedIndex = -1
    End Sub

You just need to re-populate your ListView with the updated datasource to reflect the changes after you paged and filter.

If you want to reset the page after filtering then you may need to write the logic at CheckBoxList changed event instead, and do something like this:

C#

DataPager pager = ListView1.FindControl("DataPagerId") as DataPager;
if (pager != null)
{
    pager.SetPageProperties(0, pager.PageSize, true);
}

VB.NET

VB

Dim pager As DataPager = TryCast(ListView1.FindControl("DataPagerId"), DataPager)
If pager IsNot Nothing Then
	pager.SetPageProperties(0, pager.PageSize, True)
End If
