C# - Trigger Event For Nested Updatepanel Not Working?
Nov 24, 2010
I 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.

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 used an Update Panel, and place two RadioButtons in Update Panel.
Radiobutton1 ID="radio1" and RadioButton2 ID="radio2"
Then I have set AsynPostBack for Both radioButton's.
Now, on Page Loads radio1 will triggered and fetch all data from Database, then when I click on radio2 it will triger and fetch all data, but if I again click radio1 It doesn't get trigger.
Same process I have done by setting PostBack on both Radiobutton's but show's same result.

I have a div with "id=ShowDetails". In my javascript I have this:
$(document).ready(function () {
UIactions();
});
function UIactions () {
$('#ShowDetails').click(function () {
alert("bingo");
}
});
The div is inside the update panel that gets posted back. When the page loads, if I click the div, I get the bingo but after the postback, I don't.

i am currently developing an asp.net project. there is a previous, next, and cancel button that the user can utilize, but the problem is that everything is broken into controls so that if they hit the browser's back button it will reset everything and take them to the very beginning. i would like to capture the onbeforeunload event and trigger the previous button click event (i.e. treating navigation like clicking the previous button).

I am trying to attach a server-side event to lookup the city/state for the user-entered zipcode in a field like the one below.
<asp:TextBox ID="TextZipcode" runat="server" CssClass="inputtext" Columns="10" MaxLength="10"></asp:TextBox>
Since there is no lost focus event to capture, has anyone had any luck getting this to work?

I 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.

I have an UpdatePanel with ContentTemplate specified. When page loads, user can do some AJAX work in other part of the page. Then, after that work is finished, I would like to update only content inside UpdatePanel, but without pressing any buttons etc. I should be done automatically using JavaScript when previously started AJAX work finishes. How to do it without manual clicking on the trigger button?
EDIT:
Ok, I've followed that _doPostBack rule, and whole page is posted.
<asp:UpdatePanel ID="panelAttachments" runat="server">
<ContentTemplate>
........
</ContentTemplate>
</asp:UpdatePanel>
<input type="text" name="test" onchange="__doPostBack('<%=panelAttachments.UniqueID %>',''); return false;" />

I 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.

When the CheckBox is checked, I would like to trigger an the Updatepannel that includes the label. Instead I get an error message "'CheckBox1' could not be found for the trigger in UpdatePanel 'UpdatePanel3'. The code snippet is as follows:

I 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.

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]....

I'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

somewhere in code, but without luck so far.

How 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:
txtOrderID.Attributes.Add("ontextchanged",....
Rather than hardcoding client-side JS....

I have a databound listbox that is inside an update panel. When selecting an item in the listbox, I want it to populate labels in a panel that are displayed in a modalpopup. When I click on the listbox, I can see that the data is passed to the labels and the modal.Show() is executed by stepping through the code. However, the modalpopup comes up but with no data.

I 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.
