Here's how I handle the paging:

First, create a property:

Code:

public int CurrentPage { 
    get { 
        if (string.IsNullOrEmpty(ViewState("currentPage"))) { 
            return 1; 
        } 
        else { 
            return (int)ViewState("currentPage"); 
        } 
    } 
    set { ViewState("currentPage") = value; } 
}

Then, create your PagedDataSource and set the CurrentPageIndex:

Code:

{ 
    PagedDataSource pgdSource = new PagedDataSource(); 
    
    { 
        pgdSource.DataSource = yourdatasource; 
        pgdSource.AllowPaging = true; 
        pgdSource.PageSize = 20; 
        pgdSource.CurrentPageIndex = (CurrentPage - 1); 
    } 
}

Then, you change the CurrentPage property on the event you want to change the page. For example, if your paging was displayed in a dropdown list, use the DropDownList.SelectedIndexChanged event to set CurrentPage equal to the selected value.

I believe the paging is sorted J.

As I understand it, the issue is, if you change a textbox or dropdown on page 1 and then go to page 2, when you go back to page 1, the new details you entered aren't saved. It's these changes guddu needs to keep.

I would assume the best way would be to update the db when the page changes?

Then the values and ID's of each control would have to be stored in viewstate as well. Then, when a page is clicked, during that event you would have to check if there is a value for the id in viewstate and then set the value of the control to the value in viewstate. The same concept is used here with CheckBoxes: Maintaining Checkbox State in a Listview

huh.during conversion i m getting error for below code
line 1 col 11: invalid NonModuleDeclaration

Code:

Protected Sub AddRowstoIDList()
    ' Loop through all the current items in the Listview
    For Each lvi As ListViewDataItem In ListView1.Items
        ' Find the checkbox in each row
        Dim chkSelect As CheckBox = CType(lvi.FindControl("chkSelect"), CheckBox)
        ' If the checkbox is ticked then add the corresponding ID to our private list
        If (Not (chkSelect) Is Nothing) Then
            ' Get the ID from the datakeynames property
                Dim ID As Integer = 
            Convert.ToInt32(Listview1.DataKeys(lvi.DisplayIndex).Value)
            If (chkSelect.Checked AndAlso Not Me.IDs.Contains(ID)) Then
                ' Add the ID to our list
                Me.IDs.Add(ID)
            ElseIf (Not chkSelect.Checked AndAlso Me.IDs.Contains(ID)) Then
                ' Not checked - remove the ID from our list
                Me.IDs.Remove(ID)
            End If
        End If
    Next
End Sub

I'm not sure why it's not converting, but just take the concept and see what you can come up with.

guddu · #39 January 22nd, 2009, 10:11 AM

can u tell me how to convert this line

Code:

' Get the ID from the datakeynames property
                Dim ID As Integer =   Convert.ToInt32(Listview1.DataKeys(lvi.DisplayIndex).Value)

for my repeater control???

Code:

int ID = Convert.ToInt32(Listview1.DataKeys(lvi.DisplayIndex).Value);
