AJAX :: Trigger An Update Panel Through Client Side?
Jan 10, 2010
i have 2 dropdownlist on my asp page.first dropdownlist value gets selected from a pop up window.now i want to fire an event from the drop down list as the drop down list index changes.The dropdownlist is in update pannel and i want to invoke the server side event of dropdownlist so that the other dropdownlist can be populated.
How can i invoke dropdownlist server side event from the clientside(javascript) so that the ajax functionality can be acieved as my dropdownlist is in update panel.
I have a gridview.The Gridview is in an update panel.I added a dropdownlist in a template column of the gridview.I have autopostback set to true.I have code working in the selectedindexchanged event all of that works great now I want to add a javascript confirm prompt on client-side change of the dropdowns,I have it popping up the confirm box, but no matter what the user selects (ok or cancel) it does not post back
how to catch update panel's request start (before partial updation request is sent to server) and response receive (before update panel is updated) events.
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?
I have update panel , in update panel i have one button control which exposes onlientClick event ( it dosent have click event to do postback to server).
and i have one updateprogress panel. So my problem is though i'm performing operation on client side , internally the async event is firing and making updateprogress panel to act (having rotation gif image) which i dont want , as it rotates for 10-15 sec more even after the operation at client side is done !
I'm looking for a way of tieing the two together, so that the client-side validation is performed before the call to the "check(this)" in the onclick event.
Edit: To be more clear, I need a way to inspect or trigger the client-side validation result of the textbox, when I click the unrelated button beside it.
Edit: I now have the button JS checking for $("form").validate().invalid, but not displaying the usual validation messages.
I have an asp.net page that is using and update panel and am including some javascript via a {script src=abc.js} tag. I have tried loading my javascript using both $(document).ready and $(window).load. Both fire on the initial load but fail to fire on an update panel postback.
Is there anything I can wire up client side that would fire regardless of the update panel? I know I can inject script server side but I ideally want to do this all client side and wire up what ever is needed the first time around.
I have following code and when I select from my drop down list the progress controls do not show and my grdiview is not being filled either. If I leave out the update panel from my code things are working fine.
In my application I am using ajax updatepannel in which there is a tab container tool having 4 tabs, in the third third tab I used ajax accordian control which has 2 panel each pannel have one gridview control a Remove button. Here what I want to give delete facility to the user upon the selection of checkbox corresponding to the particular record. But when I click the button it doesnot triger the button click event of the remove button.
I have a Gridview select button and whole gridview enclosed with Update Panel + trigger on select. I found CSS of Gridview lost on select. How to deal with this ?
I have an updatepanel in masterpage and information on a repeater within the panel. I want to update this information from the content page, when a user clicks a button in the content page.
[code]....
I tried this but since button control is in the content page compiler can't find the control.
I need to do a partial update of a page using an UpdatePanel but I want to throw it using onkeydown. Is there a way to do this by creating a custome asyncpostback trigger.
when I click on a record in gridview it should call the SelectedIndexChanged event and do some operations.
SelectedIndexChanged event is working OK, but when I put the gridview inside ajax updatepanle SelectedIndexChanged event will not response even if I add AsyncPostBackTrigger trigger for SelectedIndexChanged event.
I have a website in ASP.NET (WebForms, NOT MVC) which has a survey form divided in several slides. Each slide has a next button that, obviously does a transition (client-side, not post back or remote request) to the next slide.In each slide I have several ASP.NET controls with their related validators. I want this validators to be triggered when I click the next button (or maybe when each input loses focus?).
I remembered ASP.NET doing client side validation on lost focus, but maybe I'm wrong... (I quit doing ASP.NET development about 3 years now, so I can't remember)UPDATE: It would be better to make ASP.NET trigger each validator when the associated control lost focus. I remember ASP.NET doing this (or am I dreaming? =P)
I would like to add a button to Update panel's trigger. But am getting an err says "Update panel can not find the button which trigger it".
I am getting "Sys.Webforms.PageRequestmanagerParseErrorException: This message recieved from manager could not be parsed. Common cause for this error are when response is modified by response.write"
I have a user control in a master page with two drop down lists. When the user selects an item out of either ddl, I want to load a specific user control inside an update panel on the content page. I can't figure out how to get the user control to trigger the update panel.
We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
How do I conditionally trigger a full page postback from a link button inside of an update panel?
I have a custom control that contains its own updatepanel with a link button nested inside of it. When the link button is pressed I want its event handler to have the option of either letting the control update as normal or doing a full postback on the page.
Here is the control hierarchy:
Page Custom Control UpdatePanel LinkButton
Event handler Pseudo code:
LinkButton Click Handler Begin If is a partial post back AND a full postback is needed Page.DoFullPostback End If End Handler
Note: I aways need the partial postback to happen. I was considering injecting a __DoPostback in the controls markup but this seems hacky to me.
I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?
