AJAX :: Shows Data In Multiple Panels
Apr 13, 2010
I have web page with multiple update panels on it, each update panel has a detail view which is bound to different data sources, since the data loading takes time so i want that when data from any source is available the update panel shows it, while the other update panel shows a progress panel till data loading is done.
I have set all the update panel to 'Contional Mode' updating and a trigger is set to them against a buttons click event. on button click i load data from Db. hoever, when i click the button all update panel start the progree bar and they load data syncronously, but i want the above secario.

I would like to make a table with 2 columns. The first column would have 4 buttons, and when you click on one of the buttons, some
collapsible panels would appear in the right column. These could be populated from a database. When you see a collapsible panel, it
would have only a few lines of text, but when you clicked the title at the top of the text (still in the panel) the panel would expand.
Is this possible with drag and drop controls, or does it need real programming on my part?

I have a page where I am using 2 update panels. The first update panel contains a form that has some validation tied to it. The second on has a simple form, but no validation. When I go to use the form in the second panel, the postback is halted by the validators in the first panel. Everything works as it should when I remove the validators.

I've got a single table, with project information and schedule information. To make the data easier to present, I created a tab control with two panels (a detailsview in each). The first tab is for project info, the second tab is for schedule info (again, all fields in the same table). The problem is, if i change info in both tabs, and then hit the update button, only the data from one tab is added to the table. I think this problem is simple to fix, and boils down to the way I have the page organized, but I can't quite figure it out.
I've boiled my code down to the following conceptualized structure:
[code]....
When you click the update button, you return to the listview, but with only the information from your current tab saved. How can I get it to update from both detailsviews?

My issues here is that this does not compile. I get "A control with ID 'LinkButtonRemove' could not be found for the trigger in UpdatePanel 'UpdatePanelFiles'." What I am trying to do is have two buttons in the item template. One that updates just the ITEM and one that updates the entire DataList. "LinkButtonRemove" is what I want to update the entire datalist. Any ideas on why this isnt working? Or how to do what I want to do?
THE SHORT VERSION:
UPDATEPANEL1
-DATALIST
--ITEM
---UPDATEPANEL2
----CONTROLS
I want one control to update the item updatepanel only and the other to update the entire datalist.
<asp:UpdatePanel ID="UpdatePanelFiles" runat="server" ChildrenAsTriggers="False" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="LinkButtonRemove" />
</Triggers>
<ContentTemplate>
<asp:DataList ID="DataListFiles" class="MediaManagerDataList" runat="server" ItemStyle-BackColor="#ffffff" AlternatingItemStyle-BackColor="#E7F4FF" OnItemCommand="DataListFiles_ItemCommand">
<ItemTemplate>
<asp:UpdatePanel ID="UpdatePanelItem" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<div class="item">
<asp:LinkButton ID="LinkButtonRemove" CommandName="remove" runat="server">Remove</asp:LinkButton>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</ItemTemplate>
</asp:DataList>
</ContentTemplate>
</asp:UpdatePanel>

My setup is as follows: I have 4 tabs of data, all of which are invisible when the page loads. The user enters some search criteria, hits the search button, and then the first tab fills up a gridview with data and becomes visible. One of the columns in this grid is a linkbutton named 'detail'. When they click on 'detail', the 3 remaining tabs go and get their data from the database and become visible. On tab#2, I have a listview which allows editing/adding of data. Here is my problem: When I click the imagebutton on the listview that puts the listview into edit mode, the data from the first tab is now shown on the second tab.
So the correct tab (tab#2) remains selected, but the other tab's data is being displayed. Has anyone else run across this? I have tried numerous combinations of update panels and triggers but I always get the same results. Also, the last 3 tabs each contain a usercontrol. I don't know if that has anything to do with it.

Just setup the collapsible panels, there are different fields within the panels that are required. When i submit the page, i get my validation summary, but if the panels are closed, then i cant tell which fields are failing.. so i wou,ld have to open each panel up again to see where i missed something. Is there anyway to have the panels open up if there are any controls that failed validation?

I have 2 collapsible panel. The first panel is expanded by default and second panel is collapsed. When I insert a user control in the first panel (about 650px height) it displays it but the content overflows into second panel header. I have autosize to none and height to 0px in the cssclass.
The content section in panel is not expanding to fit. However if any place any amount of static text it works perfectly. Also when I collapse the first panel the rest of the panel is disappearing when an user control is used. Am I missing something. The same problem when I tried to used ajax accordion
<asp:CollapsiblePanelExtender

CollapsedText=""
ImageControlID="Image1"
CollapsedImage="Images/accordion_active.png"

I have a page that has 3 nested repeaters. For the first two repeaters, the repeater's ItemDataBound event binds the next lower repeater. This works fine for the data that I have, but causes a large amount of data to load all at once on Page_Load. Is it possible to use collapsible panels with nested repeaters in such a way that the data only loads when the user clicks a particular linkbutton?

I'm looking for a way to use custom ASP.NET validators to validate input, without using UpdatePanels, and without a full postback. The validators do several things - not just length/regex, but some other non-standard stuff as well. Javascript is required for our users, so I don't have to worry about normal users who have javascript turned off. I see several options, but none are ideal:
1) Suck it up and use UpdatePanels. I'm in the "UpdatePanels are evil" group, so I'd prefer not to do this.
2) Without using validation controls, manually validate the fields by passing the values to a PageMethod static method, via jQuery or any other AJAX framework. This would require client and server coding each time I needed to use a validator.
3) Use jQuery (or any other javascript framework) validation for client validation, then if they somehow get by that, have server-code validation controls for full postback. This would require all of the validation rules to be written in javascript as well as C#. I don't care about the full failed postback at this point, because the javascript validation would catch real users who weren't trying to screw me over.
Is there alternative out there for using real CustomValidator controls, with partial postback, C# code only, for validating input without UpdatePanels and without a lot of redundant javascript?

I'm using ajax 3 tab panels on my web page, whenever my web page is loaded i need to disable rest 2 tabs (to grey out with no click events).
when i tried to do this from server side, the tabs are completely hidden instead of disabling. My actual requirement is to use tab container as asp wizard control.
i'll be having form fields in my first tab with submit button, when the submit button is clicked, then the disabled second tab will be enabled and in the the second tab when submit button is clicked the third tabpanel needs to be enabled just as a wizard control.
i can use wizard control but, i'vent found any styled asp.net wizard control. How can i disable rest of the 2 tabs when the page is loaded.

I have a page with 5 buttons on top. I want the area below the buttons to contain an update panel that will display button 1's panel if they click button 1. If they click on Button 2, then I want button 2's update panel to replace the button 1 update panel. Each panel has stuff on it like check boxes and text boxes.
Is there a way to do this? Is there a more efficient way to do this?

I am working on a project at work and have been trying to implement the modalpopup extender. I have it set to display when invalid criteria is entered and the user tries to save the item. The problem that happens is that it will display correctly for about the first 3-5 times, but then after that the entire popup (messagebox/background) displays behind the content behind all the content, which are within panels. I have tried changing the z-index amongst the popup to something really high and keeping the panels' z-index very low, yet it still does not seem to work.

I realise that there are many posts on update panels and repeaters but none that quite solve my problem. I have a page with two Repeaters each inside seperate update panels. They sit next to each other one on the left and one on the right. The left repeater is filled from my database on my page load event. Im am storing the data in a List<> and then binding the list to the repeater. This works correctly and displays all my results. Each item in the left repeat has a button aswell. The button needs toremove the data from the left repeater and place it in the right repeater. I only want the database to be accessed in the Page_Load and then never again during the use of the page, until the data is saved (I have not got to this feature yet). So I have decided to use List<> objects.

I'm using two update panels, and in the Page_Load, I'm calling if (masterPageScriptManager.IsInAsyncPostBack).Is there a way to test where the update came from and only refresh the affected panel?

I have a page that display a record set inside an update panel. There are also a handfull of checkboxes/textboxes that allow filters to be placed. Each checkbox/textbox is set as an async trigger for the update panel and set to autopostback.
If a single checkbox is clicked the whole filter/render process takes roughly 1.5s.
If I check a filter and then several more before the intial postback is complete I get a postback time of somewhere between 20-50s depending how many boxes I've clicked.
I notice (via firebug) when I check a box that triggers an async postback and than another box the original async post back is aborted. And yet it seems like it still executes (or maybe locks?) something on the server.

Suddenly all update panels in my website became unknown elements. They work fine when I run site.
But:
no intellisense in update panel (no properties appear, no tags, like "triggers")
no ID property when I drag updatepanel from toolbox
VS says that I check if webconfig contains reference to System.Web.Extensions
But I have this reference already.
