AJAX :: Pass Parameter And Trigger UpdatePanel Update?

Feb 22, 2010

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.

UpdatePanel Update Without Trigger Button?

Jan 12, 2011

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;" />
</td>

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 :: UpdatePanel Conditional Update OnLoad Event / Updatepanel To Update On Queue?

Aug 25, 2010

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.

AJAX :: Make Each ListItem Be A Trigger For An UpdatePanel?

Jun 6, 2010

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.

I am building a system for a school project. I currently have several Update Panels on the page that have many different controls on them. I also have a single Label control that i use to display messages to the user. I would like to have this label within an update panel also but there are literally hundreds of triggers that would require it to be updated and i dont want to type an absurd number of triggers for this one control.Is there a way for me to have this one panel update regardless of what happens?

AJAX :: Trigger UpdatePanel Refresh After Page Loads?

Feb 16, 2010

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.

<code>

AJAX :: Adding Trigger To UpdatePanel From Content Page?

Sep 10, 2010

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 :: Couldn't Find Control For Trigger In UpdatePanel

Mar 12, 2010

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.

AJAX :: Using Textbox Onchange To Trigger Updatepanel / Gridview?

May 25, 2010

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....
