C# - Trigger Event For Nested Updatepanel Not Working?
Nov 24, 2010I have the following situation:
Updatepanel
dynamically loaded Usercontrol
Button
UpdatePanel2
I am loading a Usercontrol with another Updatepanel inside of it. Now in this usercontrol, i have a button which is registered as an async postback trigger for the 2nd Updatepanel. However when I click the button, nothing happens. While debugging, it does not even step into the Click event of the Button which sits in the usercontrol of course. The Parent Updatepanel ist set to Updatemode conditional and hildrenAsTriggers="false". The nested UpdatePanel2 is set to Updatemode=Conditional. I just want the Parent Updatepanel to do nothing and the button to fire its event so that I can load some data in the nested updatepanel.
AJAX :: How To Trigger Updatepanel Postback From Another Updatepanel
Mar 4, 2011 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?
AJAX :: Make Each ListItem Be A Trigger For An UpdatePanel?
Jun 6, 2010I have a problem and i have been stuck on it for a while now: I have a ListBox generated dinamically on the page at the first init of the page. That part of the page will never make a postback again while being used.
Say i have 10 UpdatePanels in the same page and there will be a maximum of 10 ListItems in my ListBox. How can i make every ListItem in the ListBox be a trigger for my existing UpdatePanels , so that when i doubleclick one ListItem , the apropiate UpdatePanel will be updated ? Or if you have any other close solutions.

AJAX :: Trigger UpdatePanel Refresh After Page Loads?
Feb 16, 2010I have seen this discussed in number of topics, but so far nothing to address my specific issue. I want to display the page the client, and then trigger an updatepanel refresh that will populate with data that takes 3-4 seconds to load (the rest of the page loads very fast). At the same time I want to display "...Loading..." text using UpdateProgress control.
Everything is working below in the sample code. However, UpdateProgress will not display unless the button is actually clicked by the user. In real production scenario I would hide the button. To invoke the immediate UpdatePanel refresh I trigger the click via Javascript. I have also tried "__DoPostBack" without success.

AJAX :: Adding Trigger To UpdatePanel From Content Page?
Sep 10, 2010I 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.

AJAX :: Couldn't Find Control For Trigger In UpdatePanel
Mar 12, 2010I've got a page with two ContentPlaceHolders. In first there is UpdatePanel with GridView. In second I located DropDownList which is trigger for UpdatePanel.
<asp:UpdatePanel ID="stanUpdatePanel" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true" >
<ContentTemplate>
GridView & other stuff
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ATDropDownList"
EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
Running the page causes error: "Control with ID 'ATDropDownList" could not be found for the trigger in UpdatePanel". I thought it was because the ATDropDownList is located inside ContentPlaceHolder. So I changed ATDropDownList's ID to UniqueID as follow:
<asp:AsyncPostBackTrigger ControlID="ctl00$ContentPlaceHolder2$ATDropDownList" (...)>
Everything works good, but I want to change it from page's code-behind. I tried to put

AJAX :: Using Textbox Onchange To Trigger Updatepanel / Gridview?
May 25, 2010How 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:

Feb 22, 2010I need to render a chart control inside UpdatePanel, I have done this part.
The difficult part is that now I need to pass parameter/parameters to server side and grab it in code-behind
so that I can use this information to render the chart.
The parameter/parameters can only be grab in client side by javascript since it is jQuery.data().
I am trying to work around this by saving it to a hidden field, that is not neat though.

May 7, 2015I have usercontrol (called A) and update panel in it
Following are the control in my updatepanel

when i hit the link button of gridview i am loading my usercontrol(B) dynamically from code behind and adding it to the DIV which is working fine. I have button inside the the usercontrol (B) and if i hit the button it doesn't trigger the action.

AJAX :: Trigger Event Added To Dynamic LinkButton Click Event?
Jun 25, 2010I have searched around but unable to find a solution that will work. I have a link button that is created dynamically during the page load. It is given an ID (obviously). There is a script manager on the page. I have the controls added to a panel in the updatepanel (updatePanel1). There is a dynamic label that is also created with each link button. I can get a response from the linkbutton click event during a postback on the second time clicking the linkbutton, but I am getting a complete postback instead of the asyncpostback for that control. During the creation of the dynamic linkbuttons, I am also creating a dynamic trigger for each button and adding it to the updatePanel1. The Click event is not firing the method without doing a complete page postback.

AJAX :: Dynamic Loading Web User Control With Gridview Updatepanel?
Jan 8, 2010Wasn't quite sure where to post this, seems like the issues could be any number of things, so I'm trying to keep it general... mods, feel free to relocate appropriately.
I am trying to build a page which will load various web user controls dynamically in response to menu selections made by the user, and then allow other interactions inside those controls (such as gridview manipulation and updates). The content page simply has a loginview, an ASP:Menu control, and an ASP:Placeholder. The placeholder is filled by the appropriate user control in response to the menu selection. Selecting a menu item causes a postback and the correct control is loaded as expected.
I realized that using dynamic loading with interactive controls would be a problem with respect to postbacks, so I added a ScriptManager to the content page and enclosed the gridview controls in the web user controls within UpdatePanels, thinking that all postbacks required by the GridView would be handled inside the UpdatePanel and not cause the parent page to refresh (which would then wipe out the dynamically loaded control). However, it does not seem to work this way. Instead, although the control containing the GridView loads correctly and displays data, when I attempt to page, edit, or select any item on the GridView, nothing happens on the first click. If I click on any item inside the control a second time, the entire page refreshes and the control and its contents disappear.
I have removed all the code inside the web user control and placed it directly into the content page to test, and everything functions correctly in that case. I think therefore that I must be missing something with how the user control is working, particularly with respect to the UpdatePanel. Is it just not possible to use an UpdatePanel to confine actions inside a user control that would otherwise cause the entire page to postback, or am I missing something somewhere?
