I have a web form for payments which consists of a DropDownList (credit card, purchase order, bill me). By default, credit card is selected, and the form (a ListView within a UpdatePanel) is loaded with the user's billing address. If the user changes the payment option, the form fields change -- for example, if purchase order is selected, the billing address + credit card fields disappear and a "Purchase Order Number" textbox appears. This is done using an AsyncPostBackTrigger associated with an event in the DropDownList.My problem is that when the form is submitted, I cannot see the user-entered values within the UpdatePanel/ListView, but I can see the original values loaded in the ListView before the edits were made. For example, if purchase order is selected, I can see the billing address from the ListView, but I cannot see the newly-entered Purchase Order Number from the ListView.Here's an abbreviated version of my code. I've bolded and commented two lines where the problem appears:

I have a listview that is retrieving some values from a database and showing them. The information are; product name, price, etc. At the end of each row, I have a textbox and a button. Within the textbox the user is able to insert how many items he wants of that particular item and by clicking the button I want the value from the textbox retrieved. It may be relevant to mention that
with the button is a event attached (OnClick) which is where I want the value of the textbox to be retrieved. The part that is giving me problem is retrieving the textbox value for that specific row when the button is clicked.

I have been struggling with DetailsView for quite some time.
Only chkActive and txtStatement in the code below are Editable. So when I click Edit, edit the fields and click Update, it does go to the ItemUpdating event, but I'm not being able to retrieve the updated values.
I get error-
Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.Label'.

I have been trying to achieve the following:
1-Allow the user to change the quantity in a textbox i.e // "txtQuantity"
2-capture the newly entered quantity i.e //int integerNewQuantity= int.Parse(textNewQuantity.Text);
3-update the database using the newly entered quantity i.e. //UpdateItem(data,integerNewQuantity)
Problem:1-I have not been able to capture the text i.e. the newly entered quantity i.e. the value entered in the text box "txtQuantity"
2-Hence the database is updated using the existing value and NOT the new value unless I make a constant assignment as below:
textNewQuantity.Text = "2"; When tested the assignment of any number correctly updates the database. see the c# code:
C# code: Version.1
protected void btnUpdate_Click(object sender, EventArgs e)
{
txtItemDescription.Text = txtItemDescription.Text + "from btnUpdate talking.."; [code]....

I have a ListView control that is inside of an update panel. I have a Button control that calls code behind when clicked and I have a trigger in the update panel that is triggered based on the click event of the button. The button that calls the code behind and inserts a record into the database works fine but I get a full page refresh and the ListView Data is not updated as expected. I then can go to another page, come back and the new data is there. I'm not sure what I missing. Please see the code below.
<asp:UpdatePanel ID="UpdatePanel1" runat="server" >
<ContentTemplate>
<asp:ListView ID="ListView2" runat="server" DataSourceID="sdsrcMessageComments" DataKeyNames="MessageId"
ItemPlaceholderID="PlaceHolder2" EnableViewState="False">

I have a webform that accepts a date range to generate PDF reports. I had to place a PostBackTrigger on the updatepanel and assign the button thaat generates the reports because the Response.ContentType is being set to "application/pdf".
The problem is I am updating the textbox value to the count of clients that are left out of the report generation in server side code, the count always come back as 0. I have tried multiple panels with no luck. The textbox is in the main updatepanel with the print button and that still does not work.

My Listview control contains 4 columns and 30 rows.I can retrieve the row number by using:
//get row of listview item
ListViewDataItem item1 = e.Item as ListViewDataItem;
int findMe = item1.DisplayIndex;
How do I then get values from one or all 4 columns?I was trying:
this.lblReponseRoute.Text = item1.FindControl("routenameLabel").ID.ToString();
UPDATE1:The final solution is:
//get row of listview item
ListViewDataItem item1 = e.Item as ListViewDataItem;
int findMe = item1.DisplayIndex;
//find label value var routeLabel = (Label)ListView1.Items[findMe].FindControl("routenameLabel");
this.lblReponseRoute.Text = routeLabel.Text;

I have a grid view that is dynamically created.In which every cell in the girdview has a 2 textbox (cTxtboxQty,ctxtWorkOrder) and 2 label.
When user click on the cell, a pop up come out and user are able to change the text inside the cell and click save.After that the pop up close and changed data immediately reflected on the screen.
My problem is:
After my data are changed and updated to database on the pop up page and having it post back to the parent page , my dynamically created textbox in gridview retain old value even new value has been assigned to it.
This sound very weird but i have no idea how to solve this.
My client side code is as below :
[Code]....
[Code]....

I have tested many times and find out that it might be the page hold the old value in memory, so that even we have updated the textbox value, after postback, it still keep and show the old value?

I have a Telerik:RadTextBox control in my markup called txtName. I'm trying to retrieve the inputed value in the code behind with foo = txtName.Text; but var and txtName always show an empty string.
Markup
<telerik:RadTextBox ID="txtName" Runat="server" Width="300px" />
CodeBehind
campaign.Name = txtName.Text.Trim();
I guess the code couldn't be easier. Basically what's happening is, when I click my 'save' button, there's a postback and the text in the RadTextBox just disappears.
update Found the problem. My web.config file had a different version of the Telerik dll file that was actually in my bin folder.

I have a GridView with a Label. The value of the Label can be calculated with a
jQuery-Method. When doing this, the (.Net-)server does not realise the change of the label, but works with the old value from the database.I tried several approaches to fix it:a TextBox behaving like a label doesn´t change anything
HiddenField: does´nt work because it has´nt a CssClass-property. I cannot raise theID of the HiddenField because I want to put it in the GridView, and don´t know howto get the HiddenField in the jQuery-Method

I built an application where I use the ListView control to display data from my database. The user will be able to see a product image, product name, a dropdown list that contains various sizes of the product, a textbox and a button. All these controls are shown for each product from my database. The user is going to be able to select the size from dd-list and enter how many pieces he wants, and click the button. I wonder if there is someone out there who knows how I can check if the user has typed in the correct textbox. I have been using the findcontrol to find the correct textbox. But it turns out that it is not working properly. I want to verify if the user typed in the corresponding textbox, where he has chosen the size of the dd-Llista.
Here is what a bit of my code looks like now:
