AJAX :: Getting Updated Value From UpdatePanel/ListView/TextBox?
Jan 8, 2011
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 want to trigger two Async Postbacks at once using UpdatePanel's via their associated buttons such as the example at the end of [URL] When you click the first button, then immediately click the second button, the first button's message never gets updated. By clicking the second button, the first async Post back seems to be cancelled. Why does this happen?
I saw this article about only allowing one postback to occur at a time here: [URL] Is this the desired behavior for Multiple update panels? Can only one run async code at once? What's the point of it being async if you can't do multiple at once? Here's what I'm trying to do overall: I want a webpage where I click a button which causes C# code to search a certain webpage and parse it. Based on the parsed information, it should automatically start searching multiple other webpages. All the while, I want the web UI to be updated with the progress.
Button Press and the client UI says "Searching..." Then the webpage is found so I want to display "Parsing..." Then the webpage parsing is complete and multiple other websites are searched at the same so the UI will display:
Webpage 1 updating...
Webpage 2 updating...
Webpage 3 updating...
Then when the Webpage 1 -3 are done updating, they change their progress message to Complete. I just started looking into ASP a few days ago and I have two ideas how to approach this problem: zy first idea was to use UpdatePanels and UpdateProgress because they seemed easy to get in there. However, the part of updating multiple webpage status messages at once doesn't appear to be possible since I can't have two UpdatePanels updating at the same time to make changes to the client UI. The one that is started second takes over the processing and the client UI isn't refreshed until that second asynch postback is complete. Ideally, there would be a way to refresh the UpdatePanel's mid postback............

I have a ListView1 control that his <ItemTempleae> has a another ListView2. ListView2 is surrounded by <UpdatePanel> with trigger and also UpdateMode="Conditional". But, I don't know why ListView2 is not being update as it should, I need to refresh all the page to see the new data enter to ListView2 only. What is the problem? How can it be fixed? I think that the problem is something in the structure. There are about 10 ListView2 with updatepanel surronded them, so when I am looking to update a specific ListView2, it doesn't know which one to update because there are lots of them. What to do in order to solve that problem?

In my web application, i have declared modalpopup extender and corresponding div(popup control) inside master page to make it generic. In my page i am using updatepanel with a button inside it. Clicking on this button will fire the modalpopup extender. Before calling show() of modalpopup i am setting some text to a label inside the popup control. But when the popup comes, the updated text is not showing.

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.

I have a usercontrol with listview control nested inside an UpdatePanel and Panel. Below is the layout:UserControl :: Panel1 -> UpdatePanel -> Panel2 -> ListViewUpdateMode is set to conditional. Panel2's visibility is initially set to false.In the containing page, I load the usercontrol and bind the ListView, turn on the panel2 and call the update method of the updatepanel (since action is initiated by an external button and not a child of updatepanel) which displays the rows successfully. However, none of the edit, select or delete actions execute the intended way. When I click any of those buttons, I can see the
UpdateProgress fine but the events seem to be not firing at all. Execution hits the PageLoad but not into any of those event handlers likeItemEditing, SelectedIndexChanging etc.

I have a page with two updatepanels both which have thier triggers outside of the panels themselves - I am setting the triggers using in the pageload event. This is how it works - there is a repeater that holds a list of links which gets set when the page loads (this is outside of the update panel). The first udpatepanel has a trigger set to the itemcommand of this list of links - it then goes out and gets the sub links and fills a repeater that is located in the update panel. - so forgetting all about the second update panel on the page... If I set the panels updateMode="conditional" then it doesn't render till I click the link twice. If I put a breakpoint in the code I can clearly see that the code is executing and that there is no error but again... Nothing renders
- I click the link again it renders. If I take out the UpdateMode="conditional" statement all is well... But I don't want that cause I two update panels on the page.
The second one also has sort of the same problem - The trigger I have set for it the ItemCommand for the repeater in update panel one... when I click one of the linkButton's in the first updatepanel sure enougn I see the code execute return my results and all seems well however there is nothing rendered on the page. BUT!!! When I click one of the main links on top (remember these are trigger for updatepanel one) my second repeater inside of updatepanel2 is shows up on the page.
What is causing the partial postback not to render anything?
I know this is confusing so I hope I explained myself well enough. I will just post the ASPX so you can see how I am setting this up - I don't think you need to see the code behind... If anyone does then I will post it.
Again - all this is to with the updateMode - when I remove it (as I did in this code sample) it works and renders however I don't want both updatePanel to get updated at the same time.

One thing I really don't like about Updatepanel is that I have to rebind almost all components in the page.
For example, I have to specify Eidit (Update) index (for inline editing) after rebind Listview using Update panel (after partial update).
It was too much job to rebind all components, so I redirected to same page and used Querystring to pass values in order to avoid all components to be updated based on one value...
If I update Listview using Updatepanel, the datapager has to be updated as well based on new Select SQL statement results.
Listview is pretty simple to update, using "Listview1.bind()" does the job.
Datapager is also in updatepanel, but it won't rebind with new results.
After post back, I'm still getting same Datapager as the orignal SQLDataSource.
In orger to "refresh" Datapager, what do I need to do??
I used to use iframe to do partial page update, but I'm having big problem using Updatepanel since simple rebind won't do the job.

I have a UserControl (UC) which is in an UpdatePanel. When the UC is loaded, I run a recursive method to set tooltip for all Button, LinkButton, and DropDownList in this UC. The problem is sometimes I only update 1 control in the UC such as a DropDownList, but I have to call the recursive method on all controls of the UC. I was wondering whether there is any way to identify which controls is updated in the UpdatePanel so that I can update correctly these controls.

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 Textbox and a few update panels. But each time the update panel clicks, then the focus on the textbox is gone So for example, we all know that when a user clicks on a textbox, there will be a blinking | symbol. But each time my panel updates, the focus on the textbox goes. Does anyone know how i could keep the focus on? as in, each time there is an update, still keep that textbox | symbol blinking.

I have two textboxes insie an updatepanel, the same update panel also has a trigger from a Clear Button from the other update panel. The first Textbox AutoPostBack is set to true. The first time when the textchanged event is fired, everything work as expected--the labels got populated, the focus is set to the second textbox. However after I click on the Clear button, i entered something to the first Textbox, its TextChangedEvent fires--the labels got populate, the focus seems set correctly to the 2nd textbox, but I
cannot enter anything to the second TextBox. it seems like the form is not active--when i hit tab, I expect the focus move to next control, instead it moves to the URL box. Turn off the AutoPostback then put a button next to the first textbox will fix the problem, but I am wondering if there is other workaround to keep the AutoPostback of the 1st textbox?

I have a textbox and an updatepanel. As I type, I want to be able to update the updatepanel. Right now, all I have is when the textbox loses focus, it updates. What is the .NET 4.0 method for doing this? Clarification: this is not autocomplete on a textbox.

How can I get a gridview (that is inside an update panel) to update/filter whenever something it typed into a related textbox outside that panel..( possibly in another update panel)?
As in Google. When you start typing, it starts autocompleting for you by looking up words in the background using the text you've typed.
I want, in effect, for a user to start typing in a textbox (say "Order #" textbox) and each time a character is typed, to trigger an update to a gridview that has a 'search param' in it's SQL Datasource SP that plugs the textbox's text into the where clause of the select inside the SP...
make sense? I have the SP and all other related code, I would just need to know how to create a JS function (preferably via server-side using something like:
txtOrderID.Attributes.Add("ontextchanged",....
Rather than hardcoding client-side JS....
