AJAX :: Dynamically Building Linkbuttons To Update A Panel Through PostBackURL's?
Oct 4, 2010
I have a pretty simple C # page that when the page first loads, a bio is diplayed in that center section based upon sql executed from my code behind. I have 4 link buttons on the page that when clicked, fill that center section with other content based upon which link button they clicked (News, Publications, Contact Info, and Presentations). I was all done, then I thought about using an UpdatePanel to get rid of the annoying "flicker" when the page posts back on the click of the link button.

I have a control that I use to populate a cascading menu with LinkButtons. All link buttons have the same OnClick event that I want to use to load content as well as change the clicked button's color to show the user which LinkButton they have selected.
My problem is that I don't know how to access any LinkButtons other than the one that is calling the OnClick event, so any colored button remains that color when other boxes are selected.
Is there any way I can reference all LinkButtons within a Panel to clear their colors so only the selected LinkButton is colored?

i have an update panel, which contains a repeater inside. The repeater's data source will change on postback. The repeater will generate a div for each item.
I need to set the height of the div that is generated by the update panel to the actual total height of the div inside the repeater.

In my webform, i have 3-4 textbox, on there textchange event i have to fetch data from database and put it on the form. I have taken another html table (with runat="server") below textbox and and in textchange event created a new <tr>, <td> and simply added contents in <td>, then finally added <tr> in the table. This is done in UpdatePanel.
When i enter something in textbox1 data is added in that table,that's fine. But when i enter something in 2nd textbox the previous data is overridden. My requirement is that if 2nd textbox's text changes than another row with appropiate data should be added, i.e., now two rows. Silimarly if 3rd ,4th textbox data changes then subsequently 3 or 4 rows should be displayed.

I played around with the Ajax Control Toolkit Framework, and I wanted to know whether it is possible to implement this:
When loading a page, a database query executes that returns a list of titles. this is quite easy so far.According to the list-count and the separate title strings, LinkButtons are rendered vertically on the page. Is it possible to also dynamically create an AnimationExtender for each LinkButton?I'd like to fade out (and delete) every LinkButton as soon as the user clicks on it, and in the same time move the LinkButtons below the faded one up by x pixels.

We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
How do we achieve this ?

I have a panel withitn an updatepanel with some buttons.
When one of the buttons is pressed, I'm updating a different update panel.
The problem is that when I click the button, nothing seems to happen.
If I click the button again , then I see the first update. If I click it again, I see the second update and so on..

i have my master page with one update panel working like a banner, so when the timer do tick every 5 sec
the image change. That works fine, but i have an update panel in my index page, this update panel works with some buttons that change the text inside the panel when click.
Now, the problem.
When i click one button to change the text and the banner change, the text returns to his default text. The update in master page is affecting the update on index page.

<asp:RadioButtonList ID="rblTest" runat="server" RepeatDirection="Horizontal" OnSelectedIndexChanged="rblTest_SelectedIndexChanged">

Basically I have a usercontrol that is setup to capture a persons education details. I want to have a button inside the update that when the user clicks loads the usercontrol below the previous usercontrol.
I have got as far as
UserControl userControl = (UserControl)this.LoadControl(controlName);
this.Panel1.Controls.Add(userControl);
however I am not sure how to keep the orginal usercontrol and not overwrite it with the newly loaded usercontrol.

I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.

A simple poll system that loads questions and possible answers.
I load questions, so that each one is generated as a DIV element and placed inside a DIV element already present in HTML markup.
Next, for each question I load answers, generate them as LinkButtons and add them to the corresponding DIV controls collection.
This all works as expected, the questions and answers are all nicely generated.
Now, all the dynamically created controls are placed in a DIV element that is inside an Update Panel.
HTML MARKUP:
HTML Code:
<asp:UpdatePanel ID ="infoUpdate" runat ="server" >
<ContentTemplate >
<div id ="info" runat ="server" >
<asp:Label ID ="infoLabel" runat ="server" ></asp:Label>
[Code] ....
The problem is, that I can't seem to register the dynamically created controls with the UpdatePanel, so when I click a LinkButton it doesn't do a Full PostBack.
Below is the sub I use to generate the controls:
vb.net Code:
Private Sub createPoll() Try
connection = New SqlConnection(connectionString)
connection.Open() ''Get the currently active poll ID
Dim sqlQuery As String = "SELECT pollID FROM polls WHERE pollStatusID = 1"
Dim myCommand As New SqlCommand(sqlQuery, connection)
[Code] ....
As you can see, I tried adding a handler to each control and then adding the control to the UpdatePanel ContentTemplateContainer, but the clickEvent never gets fired.
I also tried adding triggers for each controls, but it made no difference.
I am quite sure this has to do something with the Page LifeCycle, but I just can't see it.

for a specific reason, which would take too much time to explain here , i do want to have a postbackurl dynamically set in my masterpage.master-file when clicking a button. here is the sample code:
<asp:ImageButton ID="btnEnglisch" runat="server"
imageurl="img/picture.gif"
onclick="btnPicture_Click" PostbackUrl="<DYNAMICALLY_CREATED_URL>"/>
note: <DYNAMICALLY_CREATED_URL> derives from either of my aspx-pages being loaded before "returning" to masterpage.master.

I've been struggling with this for several hours now so I thought I'd give this forum a try. The problem is that I'm adding two kind of buttons (editBtn and delBtn) which show up fine but they won't fire their respective method when clicked. I also have a third button which works just fine.

I have a checkbox inside a update panel. Based on certain conditions, I set the autopostback property to true and also attach a event handler as below
chkBox.CheckedChanged += new EventHandler(this.ChkBoxChaned_Click);
But when the checkbox is checked/unchecked, autopostback happens but the event handler does not get hit.

I have a user control, that has an update panel and update progress control in it.
I use this user control in more than 1 location on the same page.... problem is, when ucA posts back, I see the update progress control for both ucA and ucB. I assume this is because it is a user control and the update panel and progress are named the same?
Either way - how do I make it so that the update progress only displays for the proper user control?

I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.
