Forms Data Controls :: Listview Paging Error With No Datasource Control?
Aug 17, 2010
so instead of a datasource control, I have a Data Access class that I'm using to populate the ListviewI added a datapager and everything pretty much works until I hit the first or last button. Then, I get the following error: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/>Also, Something was mentioned about ClientScriptManager.RegisterForEventValidation - - couldnt' really find an implementationI tried setting:EnableEventValidation="false", but then, all I got was squirelly interaction with all the numbered links (sometimes having to double click them, etc) - no matter what I tried from there on out, even when I removed the enableEventValidation property altogether.

I have a question regarding the listview control paging and preserving the state of the items on page change.
I am using listview control and datapager control to achieve paging in the listview control.
I use the listview to display list of questions like with radiobutton list options as answers...
I am unable to preserve the selection of answers between the page changes..
for eg : I If select option1 for the question1 and move to a next page. and If I come back to previous page, the selection goes.
I tried using the view state...but could get this working..

I'm using a datapager control on my listview to perform paging in it.When paging through the table, I need to perform some validations. When these validations are not successfull, the paging should be cancelledI currently perform the validation in the PagePropertiesChanging event of the ListView, however, the arguments do not provide a Cancel property.

I've got a big problem here with the ListView control. Basically I've got very basic code, yet it seems to break the control completely.
Here's the deal, I got a simple ListView using an ItemTemplate containing a hyperlink. Obviously the hyperlink has to lead somewhere after clicking, so the datakeys enter the scene since I need to hook up a hyperlink containing the Id of the record it's in as a parameter.
Normally this shouldn't be a problem, so in the itemcreated event I look up the link control and add the url using data foud in the datakeys.So far so good, this all works out fine.
Now this contains a number of records, too many to display on one page, so I decided to implement paging by using a DataPager, which is the way to get the ListView to support paging. This didn't work.
After a little tinkering around with the code, I found that if I didn't get any datakeys in the itemcreated event, that it all works fine. However, I need to use the datakeys or I won't be able to hook up a url to the hyperlink.
Basically, that one line of code completely kills paging. Commenting it out immediately sets things right, but that's not an option.

If I disable the ViewState on a ListView, the events raised by it are no longer ired. OnPagePropertiesChanging is the ListView event I've always used in combination with the DataPager to update the ListView to the correct page once a DataPager item is clicked, but since its not being fired, I'm wondering if there are any other options. My ListView is currently in an UpdatePanel, and I'm caching the results that the ListView is being bound to. I could rebind the cached results on the PageLoad, but I can't think of a good way to determine if the PageLoad is being accessed because the DataPager was clicked, or for some other reason, so this doesn't seem like a good idea

I have a ListView control that makes use of a DataPager. In each row of the ListView there is a text box where the user will enter some notes relevant to that particular record. Then they use the DataPager to navigate to the second page of records. If they then return back to the first page in the ListView the text they entered is gone.
Question: Is there a way (through use of a paging event or databound event maybe?) to retain the textbox values between paging events ?
I would like the user to be able navigate backward or forward and still see the text heshe has entered.

I was wondering if there were any decent tutorials on paging the records in a ListView using a DataPager (Pager Control). I can get it to work with Drag and Drop but I can't seem to find a decent tutorial on doing it programmatically.

I have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?

IN the page_load I kept like this:
===========================================
LinqDS.Selecting += new EventHandler<LinqDataSourceSelectEventArgs>(LinqDS_Selecting);

{
e.Result = ObjectDS;
}

I have a form with several controls. I'm trying to read from database and navigating through single record per page. I'm displaying a single record but not navigating through. My customerID field is the primarykey. But there are gaps btw records (1,2,5,6,10...etc). Some of them were deleted.
myPage.aspx:
<%@ Page Language="VB" Debug="true" CodeFile="customer.aspx.vb" Inherits="customer" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<form id="form1" runat="server">
Customer ID: <asp:Label ID="lblCustomerID" runat="server" ></asp:Label> <br />
Customer Name : <asp:Label ID="lblCustomerName" runat="server" ></asp:Label><br />
<asp:Button ID="btnPrev" runat="server" Text="Prev" OnClick="Prev_OnClick"/>
<asp:Button ID="btnNext" runat="server" Text="Next" OnClick="Next_OnClick"/>
</form>
</body>
</html>
code-behind:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Dim myReader As SqlDataReader
Dim myConnection = New SqlConnection("server=myPCSQLEXPRESS; database=CustomersDB; uid=myPC est; Password=; Trusted_Connection=yes")
myConnection.Open()
Dim myCommand = New SqlCommand("SELECT * FROM Customers", myConnection)
Dim intFirstRecord As Integer = CInt(myCommand.ExecuteScalar())
myReader = myCommand.ExecuteReader()
If myReader.Read Then
lblCustomerID.Text = myReader("customerID")
lblCustomerName.Text = myReader("CustomerName")
End If
myReader.Close()
myConnection.Close()
currentRecord = lblCustomerID.Text
End Sub
Sub Next_OnClick(ByVal sender As Object, ByVal e As System.EventArgs)
Dim myCommand As SqlCommand
Dim myConnection As SqlConnection
Dim myReader As SqlDataReader
myConnection = New SqlConnection("server=myPCSQLEXPRESS; database=CustomersDB; uid=myPC est; Password=; Trusted_Connection=yes")
myConnection.Open()
myCommand = New SqlCommand("SELECT TOP 1 customerID, CustomerName FROM Customers WHERE customerID > @customerID", myConnection)
myCommand.Parameters.Add("@customerID", SqlDbType.Int, 5).Value = currentRecord
myReader = myCommand.ExecuteReader()
If myReader.Read Then
lblCustomerID.Text = myReader("customerID")
lblCustomerName.Text = myReader("CustomerName")
End If
myReader.Close()
myConnection.Close()
End Sub
I'm being able to read first record. If I click Next button, my page goes to next record for only once. If i click several times, nothing happens. Does not go to next available records.

I have a need to add a new report to my page, the differnent parts of the page are all using a objectdatasource to populate the data. The new report because of all the data being returned i have started to use a repeater and a table in the ItemTemplate. Just binding the objectdatasource to the repeater works fine, but returns all the records and causes the page to be very long. I found this link for adding paging to repeater, but its setup different than what i have
[URL]
Is there any way to use what i have already and add paging to the repeater?

I am trying to experiment with things as a beginner and want to use paging in Repeater Control. Since Repeater control is light weight, I want to use that. I have heard of two methods: PagedDataSource class and the other that I dont remember. I wanted to attempt both of them. How do I proceed?
