AJAX :: Display Messages From Server Side Using ModalPopupExtender
May 7, 2015
I'm using asp.net and c# to build a web application. I'm trying to display a popup message using the ModalPopup extender. The message displays fine only if it sets in client side or in server side but inside Page_Load. Otherwise, it displays as empty. the popup comes up without the message.
The thing is that i want to change the meesages when i call its show() method.
I have a panel extended by the ModalPopupExtender that is sometimes shown using the .Show() method in my code-behind. I have a javascript function that resizes the popup and am able to get it to run when I use the client-side show function but how do I run the same javascript function when using the server-side Show() function?
I'm using a ModalPopupExtender in my website, to show "accept/cancel" messages, and catch the user selection at the server side. I put two buttons (ok/cancel) at the panel that will be shown as a modal popup, add them a server side event handler, but it does not fire.
I have a gridview that displays items awaiting supervisor approval. The supervisor clicks the Review button and a modal window should popup with the results of a database query on the record. I am using a dataketname param on the grid. Here are the ASPX elements, The gridview and the modalpopup code
[Code]....
I am using mpeApproval.Show() in the codebehind but it isn't firing. I've been at this literally all day and am feeling pretty stupid at the moment. Have I provided enough for you to make a determination?
Initially, ModalPopup Content Container is an empty control.After user clicks on the Button, a async postback will be triggered. During the postback, the server generates the content and appends to ModalPopup Content Container.Also sets the properties of ModalPopupExtender. Finally, calls ModalPopupExtender.Show() method and UpdatePanel.Update() method to show the modal popup.
This method works fine if all controls in ModalPopup Content Container contains simple control. If a control is a button that needs to postback to server side, that is a problem.Since the controls in ModalPopup Content Container is dynamically created. If a control in ModalPopup Content Container triggers a postback event, the control must be created before RaisePostBackEvent is called in server side.
My idea is to determine whether the ModalPopupExtender is hidden or shown in client side in order to re-generate the dynamic control in ModalPopup Content Container.So my question is how to determine a ModalPopupExtender is hidden or shown.
I have a print button and I want to trigger the modalpopupextender and trigger the server side Button1_Click Sub.The print button calls a function that constructs a html table with the values of the gridview selected row.How can I open the modalpopupextender and trigger the server side function at the same time with the same button?
I'm using what I believe is a pretty common/boring/generic implementation of a ModalPopupExtender. I'm using client-side JS to show the dialog when the user clicks a link, and hide it if they click "cancel". I only do a postback if they truly want to save the data.
I can click the link to show the dialog, then click the cancel button to hide it, then click the link to show it... ad infinitum. If I decide to save the data via a postback, everything works well, and the dialog is hidden as a result of the postback, all as expected.
However, once the postback completes, my client-side JS show() never works again. Any attempts to click the link fail quietly; no error messages, the dialog just never shows again.
I've been prototyping the use of the ModalPopUpExtender but find that the BackgroundcssClass fills the entire screen even though I have defined the width and height. So when I click on link button the popup fills the entire window and the X/Y positioning has no effect. Other than that the content displays fine. Any thoughts on this issue?
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?
As far as I can see, the following code should make an AsyncFileUpload display in ModalPopupExtender. The MPE shows fine but the AsyncFileUpload doesn't load inside it. I also tried removing the update panel and putting the divs both inside and outside of the update panel, all with the same (lack of) results. And the AsyncFileUpload displays and works outside of the MPE.
I want to display a Modalpopupextender when user clicks on the link, but the above code does not work, it does not give an erorr but does not work too.
On one of my pages I've got a popup window implemented using the ModalPopupExtender. The content html of the popup is retrieved from a webservice dynamically (using DynamicServicePath, DynamicServiceMethod properties of the extender). Everything works fine, however there is a minor problem: web service call takes about 2 seconds and the popup panel is blank during this time, which confuses the users. I would like to display 'Loading...' message in the popup window (or an animated image, does not really matter) during the webservice call. Is there a way to do it?
I have a submit button that saves record successfully.
The problem i have with it is that it can only show ModalPopupExtender after the first save(first click of the submit button).On the second click of the submit button it doesn't show ModalPopupExtender even though record is saved.How do i go about it.
In a gridview there is 4 columns i.e. application no,name,couse,more.. (linkbutton). When we will click more.. button of any application no, then in a popup window all information of that particular application number will show.
I reordered some items in a listbox using Javascript. When I read the items in a postback in the code behind (ASP.NET), the order is in the original order. How do I get the same order as shown in the screen after Javascript manipulation?
I m using site login Control in my login.ascx file and disaplaying login control in Div so if there is login link in page and i click on that then Login Div will popup which is site login.May i know how can handle error like username or password is incorrect on client side instead server side?
in a form i have a buttoin, when click both OnclientClick and postback should happen. on clicking the "Email" button a client side "mailto" tag should do the work and pull a new message window on the client's machine.
whereas, the email addresses should be invoked by the post back. so , when clicking the button the server side post should happen and on return the client side script should be invokded with the values read during post back, and populate all the email addresses.
i need know how to first do a server hit take the values and then execute the client script with those values without using AJAX
I am calling server side methids from client side using PageMethods. Can those methods return value back to client side. If yes then how and if no then how can that be achieved? refer to my code below.
I am using VS2010 and .NET4 for a web app. I have a script manager/update panel that has a couple of grids.
The client just leaves the page opens and views an updated grid every 30 seconds or so.
I want to refresh the grid by calling the server side method to load the grid, but not load the whol page using meta refresh or similar (too much screen flicker and unnecessary bandwith).
Is it possible to set some timer using javascript or something and call a specific server method to refresh controls?
