AJAX :: How To Change UpdatePanel Content From Another UpdatePanel
I have a dropdownlist, that causes a postback. On the SelectedIndexChanged event, is it possible to force a placeholder that is within a different UpdatePanel to change it's visibility?

For example, when the SelectedItem.Value of DropDownList1 is "1" then show Placeholder1, otherwise hide it.

What I am most interested in is how to configure the UpdatePanels to allow this.

AJAX :: Add Or Remove Control Dynamically?
Suppose I have two controls in my page named Textbox1 (For the purpose of taking Employee ID as input) and another one is Button1.

I am using northwind data base and my server name is "DON".

The thing which i want is that when i click on the button1 the task showing below should be:

1. Disable the page (Like when we download the Ajax Tool kit from the Codeplex. An agreement come and the page gets disable)

2. A panel should be display as Image Shown Below

Is it Possible with the help of query string (if yes please make your answer query string oriented) a close button should be appear also in the top right corner of panel which should close the panel and re enable the form.

Remove Controls Dynamically (using Ajax)?
I wrote this code and it works perfectly to add controls.

When I click on the link button "Add group" it correctly adds new DropDownLists and LinkButtons, the problem is that the removeGroup function (which is added also dinamically) does not work.

Here is the code:

[Code]....

The panelGroup is within an UpdatePanel.

AJAX :: UpdatePanel Content Not Centering
I'm having an odd problem. I have a <td> that is set to align it's content in the center. There is a label at the top of the TD that is centered. But then I have an UpdatePanel, and the content of the update panel is not centered. I tried clearing the browser cache, and everything in between but for some reason all of the contents (two GridViews) of the UpdatePanel will not center.

AJAX :: UpdatePanel On Textbox Content Change?
I am 100% sure this question has been asked before and I am really sorry if I have been blind in not being able to find it through searching, I have tried! :o)

First off, I have a text box which updates an UpdatePanel when clicked off, however I want the Panel to update as I type another character without changing my cursor focus.

AJAX :: Adding Trigger To UpdatePanel From Content Page?
I got an updatepanel which contains a normal panel on MasterPage. The updatepanel does not contain content place holder. On the content page, I have to add triggers to updatepanel for buttons that are dynamically created on "page_load" event. The problem is that, since the page_load event of content page is being called before master page's page_load event, UpdatePanel is not being created. So that, whenever i try to add triggers in page_load event of content page, i got an error like "A control with ID 'ctl00$editableContent$ctl42' could not be found for the trigger in UpdatePanel 'up1'."

The code below is for adding triggers to updatepanel for buttons.

MasterClass master = (MasterClass)Page.Master;
AsyncPostBackTrigger trig = new AsyncPostBackTrigger(); [code]....

AJAX :: UpdatePanel Not Working For RadioButtonList In Content Page?
I have the same problemas [URL] However, the solution doesn't work for me since I'm using .Net 4.0 and xhtmlConformance is not there from start.

Basically, using a master page, the RadioButtonList still do the whole page postback even it's in the UpdatePanel. When I put the exact same code in a standalone page without a master page, it works as expected.

Master Page:

AJAX :: Updating Content Within A Placeholder (updatepanel) Using A Timer?
GOAL: on a web page (vb.net) content in a placeholder will refresh with a different .ascx (user control) every 30 seconds (rotating 3 in total) and of course i dont want to refresh the whole page, just the placeholder.

I'm new at AJAX (that's my first problem - lol)

I set the timer up to call a function, but not sure how to go about refreshing the placeholder with a different ascx file.I'm sure i'll be using UpdatePanel to do this, but haven't been able to figure this out.Easy to replace a value in a label using AsyncPostBack trigger, but nothing on howto achieve this.

AJAX :: Dynamically Adding Controls To A Page With An Updatepanel?
I amdynamically adding controls to a page with an updatepanel. The controls do trigger a post back but their events do not fire.

For example:

LinkButton link =
new
LinkButton();
link.Height = 45;
link.Width = 250;
link.Font.Underline =
link.Font.Bold =
link.ValidationGroup = "NoValidation";
link.Click += new
EventHandler(EventDoesNotFire);

I have set a break point on the Load_Page and in the EventDoesNotFire method. The Load_Page fires, but it never enters the EverDoesNotFire method.

AJAX :: Dynamically Adding A Link Button To An Updatepanel
I have gone through several posts on this forum about adding a linkbutton to an updatepanel dynamically. A lot of them say just give it a unique ID and some say you have to register add an AsyncPostBackTrigger to the triggers collection. I have tried both and neither work. I have this simple test that I created - the code is below - there is nothing else in this project but the code you see so I know nothing else is interfering with it.

I have also seem people complaining that the linkbutton causes the entire page to postback - in my case nothing happens... I have seen people talk about having to add the triggers on the page init however I can't do that - I am dynamically creating menus based on a selection in a listbox... (not in this simple test but in a larger project) I am using Visual web developer express 2010 if that makes any difference.

AJAX :: Use Dynamically Created Button To Update A Label In An UpdatePanel
I have some code that I am working on that uses an UpdatePanel and some dynamically created buttons to perform functions. The problem is that the dynamically created buttons aren't working the same as my test static button, which is behaving exactly as it should be.

So I was wondering if someone would be willing to simply post an example (in VB.NET or C# please) of the following:

An UpdatePanel has a Label and a Placeholder inside of it

The Placeholder has a dynamic button added to it

Clicking on this button will make the Label say "Hi" without performing a full page postback.

If I can just get that much to work, I am sure that the rest of the code will be fine. I just can't seem to get my dynamic buttons to act like my static ones do in an UpdatePanel.

AJAX :: Tab Container W/ Dynamically Added Tabs - Content Mixing On Postback
I have a page with 4 fixed Tabs. Tabs 1 and 2 are always in position 1 and 2. However, the users are allowed to create their own tabs and add their own html content. I do this by creating a new tab in codebehind and inserting it into the tabcontainer AFTER the frist 2 and before the last 2 tabs. There could be several of these. EX: "F1 | F2 | U1 | U2 | U3 | F3 |F4" where F is a fixed tab and U is a custom tab.

As long as ALL tabs are visible then everything works fine after postbacks.

Based on user settings I sometimes hide fixed tab 1. Everything loads fine the first time. However, on postback The content on fixed tab 4 (always the last tab) is displayed on the bottom of EVERY tab (fixed or custom). It is still displayed in fixed tab 4.

A little background on the code:

Since the tabs are added dynamically they do not exist on postback and must be re-generated every time. This is done in Page_LoadComplete. I have tried it on PageLoad and it behaves the same way.

If I do not re-generate the pages on post back then the problem goes away - as do the custom tabs.

The only thing I could find was from last year, and was supposedly fixed (http://www.codeplex.com/AjaxControlToolkit/WorkItem/View.aspx?WorkItemId=16321

AJAX :: Refresh UpdatePanel At Content Page Asynchronously From Master Page?
I have master page

MyMasterPage.aspx and content page MyDefault.aspx.
MyMasterPage.aspx has one input button [value="Menu-1"]. When user click the button, the button will pass value "Menu-1" into
TextBox1Default1 at content page MyDefault.aspx, and then refresh
UpdatePanelDefault1 at content page MyDefault.aspx asynchronously.

My problem is the post back is full post back when refreshing UpdatePanelDefault1. I would like asynchronously post back during refreshing UpdatePanelDefault1. copy the full code MyMasterPage.aspx and MyDefault.aspx below, and then paste / overwrite it into your blank aspx page for testing. I am using VS 2008

Below is full code MyMasterPage.aspx.[Code]....

Remove Unwanted Id For A Control When Declared In Content
Consider sample piece of code in asp.net which has a master page associated with it

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolderA" Runat="Server" >
<asp:TextBox ID="TextBoxB" runat="server" CausesValidation="True" Height="96px" Width="426px" />
</asp:Content>

When the page is rendered in browser id generated for textbox with id "TextBoxB" is

ctl00_ContentPlaceHolderA_TextBoxB

Below is the equivalent html code.

<input name="ctl00$ContentPlaceHolderA$TextBoxB" type="text" id="ctl00_ContentPlaceHolderA_TextBoxB" style="height:96px;width:426px;" />

Is it possible to have same id of TextBoxB in both HTML and aspx page.

MVC :: Can Dynamically Add Or Remove Inputs On The Form
do have a very particular question and if you want to answer it go straight to the end. But I do welcome comments and advices hence the lengthy post. we deal with a lot of forms and some of these forms are quite lengthy and have many fields. We also have a requirement - in addition to top level fields - to be able to have variable number of repating rows - as we call them. For example, let's think of a customer which has name, surname and age while it can have zero or many addresses (say 0 to 10) so the user must be able to add or remove contacts from the form while filling it in.

Web Forms :: How To Dynamically Remove Treenodes
This one is giving me a real headache for the last couple of days. I'm wriing a TreeView and this is how it should work. Tree view has set of nodes and each node contains set of other nodes as well. Based on the logged in users access rights I want to remove some nodes. I'm getting access rights as a string from the DB and looks like this

frmAdminRegisterWindow,Admin,1,;frmAdminUser,Admin,1,;Admin,,0,;
<NodeName>,<ParentNodeName>,<Visible>
Here is the deal
I want to remove the treeNodes and I tried this code
if (readOnly == "0")
{
treeView1.Nodes[nodeName].Remove();
}
which gives an exception to me stating that "Object reference not set to an instance of an object."
This is the code segment I have above that if statement to add the Nodes
treeView1.Nodes.Clear();
//NOTE: Node name has to be applicatin wide unique name
//User Administration
TreeNode Admin = treeView1.Nodes.Add("Admin");
Admin.Nodes.Add("frmAdminUser", "User");
Admin.Nodes.Add("frmAdminRegisterWindow", "Register Window");

So if the nodeName = Admin it should remove the TreeNode Admin, but instead I'm getting the above exception.

AJAX :: How To Trigger Updatepanel Postback From Another Updatepanel
I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.

How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?
