I am developing an asp.net web application and stand on jQuery plug-ins for any aspects of my Interface. But unfortunately I have to use AJAX only for its UpdatePanel to enable partial rendering. Is there any way to use jQuery for partial rendering and act such an UpdatePanel?
View 2 RepliesHere's my situation:I've got a parent UpdatePanel (with ChildrenAsTriggers set to false and UpdateMode set to conditional) that contains a webpartzone which loads webparts with user controls inside them at runtime. Both the parent UpdatePanel and the child UpdatePanel (also set to ChildrenAsTriggers=false and UpdateMode=Conditional) obviously have triggers set up that are relevant to them.
The problem is that whenever the parent UpdatePanel fires an asynchronous postback, the child UpdatePanel in my user control gets fired off as well thereby causing my user control to be re-rendered. I don't want this to happen. Outside of initially loading the user control, I want that user control to only get updated/rendered again when a trigger inside itself is fired,not when the parent (outer framework) fires off one of its triggers. A ParentAsTrigger property (set to "false") for the child UpdatePanel would be perfect if it existed.
Note that I've tried eliminating the child UpdatePanel inside the user control and then loading the triggers for those controls to the parent UpdatePanel at runtime, but that doesn't work because the user control is being invoked within CreateChildControls() -- I get an exception when I attempt to do that.
If I set up a repeater that has LinkButton controls, an UpdatePanel works great. If I add child elements to the LinkButton,such as SPAN, the UpdatePanel stops working as expected. If you click on the area of the LinkButton everything still works, but if you click on the area of the SPAN inside of the LinkButton, you get a full PostBack.I've tried setting ChildrenAsTriggers to true and a few hundred other things. Nothing seems to work. I think the UpdatePanel sees that the "click" event happened on the SPAN and doesn't know to capture it for an async postback.

i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:

the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.
I have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.

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.
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?
i have a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.
all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.
but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.
What is the best way to use jQuery Templates with GridView to achieve similar functionality of an UpdatePanel, such as add/edit/delete data without PostBack?
View 2 RepliesI have two update panels and one javascript control.
When the javascript button is clicked, it forces a partial postback on UpdatePanel2. UpdatePanel2 is populated with dynamically created buttons that have javascript effects (jquery) but when click can also induce a postback. My problem is that, when clicking on these dynamic buttons, the whole page does not do a partial post back but rather UpdatePanel2 itself does a partial postback and everything is gone.
However, what I want to do is be able to tie each of the dynamic buttons in UpdatePanel2 (After being dynamically created) and make them an asychnonous triggers to UpdatePanel1. So that when clicking on these dynamic buttons, ONLY UpdatePanel1 is doing a partial postback refresh. UpdatePanel2 stays put and remains the same.
i have Linkbutton inside updatePanel and when i click on it it returns following error
An extender can't be in a different UpdatePanel than the control it extends
I have a script inside an updatepanel. This script needs to be inside the updatepanel as it must be located in that spot.
Now when we click the "LinkButton" to update the updatepanel, the script will dissapear.
It seems that the script only is initiazed on the first Page_Load and Refresh of the page.
How can we keep it when pressing the "LinkButton"?

I am trying to trying to setup an updatepanel to update every X seconds, the problem is I don't want the control to actually refresh unless there is new data. So I currently have a child updatepanel in a parent UpdatePanel, the child updatepanel gets refreshed by a timer. But I can't seem to find a way to trigger the parent panel to update. Again, only when certain conditions(data changed) are met.
Sample Code:

I am using two Updatepanels in ASP.NET AJAX and as soon as there is some event in first updatepanel, it will get refreshed at that time I want my second Updatepanel getting refreshed too. How can I do that ?
View 2 RepliesI have a page that has a updatepanel around a gridview control that is within my modalpopup. So you land on the page, there is a link that when clicked will open the model popup. Initially the gridview merely displayed saved records you personally choseto save, well when you selected one, the popup would close and the data from that row would be passed to the gridview within the page to display details.. no issue when it was setup that way.. well eventually it was decided to add a delete option within themodal popup gridview so now when viewing the records you can delete it if not needed. works well.. but now with the updatepanel surrounding the gridview when i click on my "select" link it doesnt execute my
View 3 RepliesI need to implement a functionality where I need to drag a tree node value to a textarea for calculation. Which is best, simplest to use for this functionality-- ajax or plain javascript or anything else?
I'm considering going at this myself because my requirements are particular and highly customized:The grid is bound to a collection of complicated objects, each of which may contain child and grandchild objects. Depending on data and context, the template'd cells vary from TextBoxes to ComboBoxes to Calendars to a combination of controlsTextBox cells have Google-style auto-complete functionality. Also each TextBox cell can expand into a small TreeView pane that allows hierarchy-navigating selection of a value should auto-complete be insufficient

View 2 RepliesOn an aspx page i am having a dropdownlist and a panel control the dropdownlist autopostback is true. in dropdownlist control there are two options and depending on the option selected by the user i display a user control containing ajax updatepanel with a timer configured to launch async request after every one second. the problem arises when user selects the other option in dropdownlist control and the user control gets changed in the panel control. The error which is occured is shown below:
Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ctl00_cphMainMasterPage_ChildContent_ctrlPinStatusMonitor_updpnlPinStatus'. If it is being updated dynamically then it must be inside another UpdatePanel.
I thnk the problem is that the last control which have launched the async request is no more available in the panel control and gets replaced by the new other user control.
Say you have a Grid which is having paging, editing and extra, I usually put the whole grid in UpdatePanel to make the page partially render with AJAX, but I hear that u can do AJAX without UpdatePanel, how is that?
