Forms Data Controls :: Gridview Paging Resets Form Controls?

Sep 28, 2010

I have a gridview which has 4 columns, each holding an ImageButton in a templateField column. When I click on one of these image buttons the clicked upon image is displayed in Image1 using GridView1_RowCommand and this works fine.

However, when I click on one of the page numbers on the gridview the Image1 control resets to its original state and loses its ImageUrl.

Below is the HTML source for the gridview.

Forms Data Controls :: Reading And Paging From Datasource?

May 16, 2010

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">
<html xmlns="http://www.w3.org/1999/xhtml">

<title></title>
<head runat="server">
</head>
<body>
<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.

Forms Data Controls :: Paging A Repeater That Is Connected To Object Datasource?

Oct 6, 2010

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?

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.

Forms Data Controls :: How To Display Large Amount Of Data (about 150.000) On One Page Without Paging

Mar 5, 2010

we have a classic ASP Webpage for displaying reporting data.

The process is following:

user inputs reporting criteria reporting criteria are passed to a method in a VB6 DLL containing the reporting business logic (generating a dynmic sql statement) VB6 DLL method returns xml data xml data are displayed with xsd transformation 150.000 datarows are displayed in some seconds (less than 10 seconds maybe) Now we want to extend this reporting function and decided to use asp.net (2.0) So I have written a little prototyp application with a SqlDataSource Object and a GridView Control.

A table with less data (about 100 or so) are displayed quickly.

But a view with about 150.000 datarows needs about 2 minutes and ended with a OutOfMemoryException!

The request of the customer is definitvely to display the data on one page like in the old classic asp application!

Forms Data Controls :: Gridview Paging On Change Page Number?

Jan 12, 2011

So my problem is as followes:

i have a gridview in another gridview (gv2 inside gv1).

in codebehind, at pageload i have: [Code]....

witch gives me a number of total records in the gv2 to a label. something like a coment number label.

my problem occures when i press the page button (allowpaging = true) on the first gridview. it acts kinda like this:

it makes the second gridview.visible = true; doest string the number of rows, and the label.text = "";

i've tried to make a code like this:

if (Ispostback)
{
gridview1.databind();
foreach ...etc..
}
else
{
foreach ....etc...
}

Also the gridview 1 and 2 the datasource is an SqlDataSource.

but that didnt work . also tried some things in pageindexchanged and pageindexchanging but still no efect :(. and also tried with enableviewstate = false / true on both gridviews with diferent combinations, but still no luck.

the code works only when i have allowpaging = false, or when im on the first page of the gridview (for the first time) is that the number of coments is pasted into the label.

Forms Data Controls :: Datalist Paging - Display Remaining Date In Next Page

Feb 25, 2010

I have a datalist inside 1 datalist.In the first datalist i am binding the "advertisement posted" date field from sql server. In the second datalist i am binding the ads posted on that date using an object datasource. my pro is, i need to show a total of 100 ads in one page. This should not depend on the date. Total 100 postings in the page. For example

Todays date (02/25/2010)
50 postings
yesterdays date (02/24/2010)

if 75 postings are there,

50 postings

it should display only 50 postings under yesterday's date remaining 25 postings should display in next page(paging) with the format like this

yesterdays date (02/24/2010)
remaining 25 postings
(02/23/2010)
75 postings

how can i do the paging like this?

Web Forms :: IFrame Form Data Capture Upon Parent Page Form Submit Action

Jun 8, 2010

I have a web form called default.aspx which has a form with user information. In addition to this, I have an iFrame on the same page that displays a page Secondary-Form.aspx that has a few additional dynamic data fields. I need to do two things.

1. I need to pass the parent form data in real time to the iFrame page to refresh its content and modify it's fields accordingly. Example: If the user submits their Vehicle Choice as Car on parent form, the form item in iFrame will display a radio button that says Honda, and if the user submits their Vehicle Choice as MotorCycle in the parent page, the iFrame will display Harley Davidson as the radio button choice

2. The submit button is on the parent page. I want both pieces of this information (from the parent page, as well as iFrame selection) to be passed to a server side ASPX page to process this information.the default.aspx and Secondary-Form.aspx files are located on different domains.

Data Controls :: Gridview Paging Is Taking Some Time (15-20 Seconds) To Go To Next Page

May 7, 2015

I had implemented the Ajax timer control to update Gridview data(along with Progress bar inside Gridview) after some interval of time.Below is the full code:

HMTL:

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
<%--style & Script for progress bar in Gridview --%>
<script type="text/javascript" src="//code.jquery.com/jquery-1.10.2.js"></script>
<script type="text/javascript" src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
<link href="css/jquery-ui.css" rel="stylesheet" />

[Code] ....

C#:

protected void Page_Load(object sender, EventArgs e) {
if (!this.IsPostBack) {
BindGrid();
} }
protected void BindGrid() {
string query = "SELECT * FROM Table";

[Code] ....

It is working fine except that the Gridview paging is taking some time(15-20 seconds) to go to next page.

DataSource Controls :: Web Form Does Not Always Insert A Row Of Data

Jun 14, 2010

I have a simple contact info webform with some validation rules developed in VS2010 that inserts a row in a SQL 2005 Express db.

However it does not always insert a row. (does for me !) There are no errors reported either in the browser or in the event log.

how I can narrow down the cause?

My code is faily simple. Basically the button calls the Insert command in the SqlDatasourcce , as generated through VS I do have one piece of code that forwards the user to a new page once the form is fillied in.
