Thisis the code I use to display an aspxloadingpanel with an ms update panel:
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_initializeRequest(initializeRequest);
prm.add_pageLoaded(pageLoaded);[code]....
However when an error occurs on this page, the loading panel continuously remains on the screen...How can I catch errors so that instead it would actually show the error.
I have the following code
[code]....
and while that presents a friendlier error message to a user, I've forgotten how to show me the "real" error.
I have some code that is throwing unhandled DivideByZero exceptions in a WebMethod. These exceptions are not being caught by the global logging in Application_Error in global.asax. why exceptions thrown from a WebMethod are not handled by Application_Error?
View 3 RepliesImagine a web service with a method that returns a Customer object, that takes a customer ID as a parameter, i.e.
[WebMethod]
Customer GetCustomer(string customerId)
Now imagine that you're writing an ASP.NET app and you've generated a proxy for the service with the async operations. You create an instance of the service, wire service.GetCustomerCompleted to your handler, OnGetCustomerCompleted, and call service.GetCustomerAsync("12345"). In OnGetCustomerCompleted you apply logic to detect that no customer was found and throw a custom exception, or you want to throw the exception found in e.Error, e.g.:
void OnGetCustomerCompleted(object sender, GetCustomerCompletedEventArgs e)
{
if (e.Error != null)
throw new ApplicationException("GetCustomer failed", e.Error);
if (String.IsNullOrEmpty(e.Result.FirstName) && String.IsNullOrEmpty(e.Result.LastName))
throw new CustomerNotFoundException();
}
(I've omitted the bits of code that sets up a Customer object and persists it through the calls.) You launch the call to GetCustomerAsync in Page_Load and expect to retrieve the result in a handler wired to Page.OnPreRenderComplete. My question is, how do you catch the exception in your page? I know you can catch it with Global.asax's ApplicationError, but what if you don't want to navigate away from your page?
i am attempting to use javascript to update the chart, because how i have setup now causes the chart to just disappear. Here is the code i have now: I am calling the chart to page using: on default.aspx
[Code]....
Code on the dataURL_Infrasturcture_Capacity.aspx page:
[Code]....
PROBLEM: So how would i update this using an update panel and timer. Currently when i do it the chart just disappears on update. I believethis is due to the fact that i am calling a dataURL. How would i get this to work javascript?
I have the following function that is trigered from an asp dropdownlist when an item is selected.
[code]....
The script sets a url depending on the selection from the dropdownlist.
It all works ok, but then the update panel updates and the javascript photogallary breaks.
How do I prevent this from happening.
i have update panel which has button inside
so when i click button, the update panel refreshed auto.
the problem is i want to fire java script when i press the button

I have an aspx page with four UpdatePanels. Incidentally, each UpdatePanel corresponds to a JQuery UI tab. What I am trying to achieve is a JQuery UI modal dialog OUTSIDE the UpdatePanels that can be called from server-side code running INSIDE any of the UpdatePanels. So, inside the first UpdatePanel is an asp:Button which runs some server-side code. When an error ocurrs, I want to be able to inject some JavaScript that will call the modal dialog to display the error message. Here is the code I am using:
Dim script As String = "showPopupMessage('{0}');"
script = String.Format(script, errorMessage)
ScriptManager.RegisterStartupScript(Me.UpdatePanelBizInfo, Me.UpdatePanelBizInfo.GetType, Guid.NewGuid.ToString, script, True)
The showPopupMessage function on the page looks like this:
function showPopupMessage(msg) {
$('#<%=Me.LabelPopupMessage.ClientID %>').text(msg);
$('#dialogPopupMessage').dialog('open');
}
When the code runs to inject the JavaScript, nothing happens. I am assuming it has something to do with the fact that the error ocurrs in the code running inside an UpdatePanel. Upon inspecting the resulting HTML, the JavaScript is there. What am I doing wrong?
I am working on an application where i have got, a content page within a Master Page. I have placed a gridview on the page. This gridview has three fields, one of them is TemplateFied, a BoundFiled and a CommandField, along with paging enabled in the gridview.
In the template field i am creating a dynamic javascript on RowDataBound.
I wanted to place this gridview in Update panel so that it doesnot re-loads when command is clicked or page is changed.
I placed a scriptmanager and an update panel, and placed the grid in it. Now my command field works only once and not more, and same is true for the javascript, it doesnt gets initilized.
I have one asp.net content page and calling .js file in that content page <asp:ImageButton> onclient click event. but it is not all calling .js file
View 3 RepliesI have a user control which acts as a footer for my website and uses java script jqdock.js to show apple type bottom menu. I added an update panel to the usercontrol. What problem I am having now is, it works fine initally but once I click the mail button which is in the usercontrol , the whole user control dissapears, after postback i guess. below is the usercontrol and code view:
enter code here
public void Page_Load(object sender, EventArgs e)
{
// Page.ClientScript.RegisterClientScriptInclude("bottomMenu", "../js/jqDock.js");
ScriptManager.RegisterClientScriptInclude(this,this.GetType(),"bottomMenu", "../js/jqDock.js");[code]....
i am using an update panel inside this i am using a jquery image upload which works fine outside an update panel, but when inside i think the javascript is not instalising. i have tried using RegisterClientScriptBlock without success.
the javascript is belo, because its a document.ready how can i make sure this is not lost in a update panel?
$(document).ready(function() {
/* example 1 */
var button = $('#button1'), interval;
new AjaxUpload(button, {
[Code]....
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 we achieve this ?
i have just noticed something strange in some asp.net markup.
I have a standard form with a couple of textboxes and a submit button.
When clicked the code behind will attempt to perform some logic and then return.
If the input values are not valid it used to throw an exception.
The moment i wrapped the controls in an AJAX update panel and try to submit bad data, no exception is thrown and the panel returns like nothing was wrong.
Does anyone know how to return this to the previous behavior whilst keeping the update panel?
In one of my webpage, I have a parent window where i have a datalist with 10 rows of images. when i click any image a pop up window(child window) opens.
The child window has a form to be filled by user. Once user fills this form, he will press the save button. Once the save button is clicked, the child window should be closed and the datalist(in the update panel) in the parent window should be refreshed.
This is how I am trying to achieve this. On click of the save button a javascript function is being called of the parent window like this: window.opener.refreshDataList();
in the refreshDataList() function I have written the following code:
{
childWindow.close();
__doPostBack('ctl00_ContentPlaceHolder1_UpdatePanel1', '');
}
This works like a charm in Internet Explorer. However in Mozilla and Chrome it doesnt work. While testing this I added an alert statement ind the refreshDataList() function like this..
{
childWindow.close();
alert("Testing");
__doPostBack('ctl00_ContentPlaceHolder1_UpdatePanel1', '');
}
Once I added the alert statement, It started working in both mozilla and chrome.
So I realize that It could be an issue related to focus. I have done window.focus()
but still its not recieving any focus and not working in Mozilla and Chrome.
The code which shown above where the problem is javascript have not function which the certain command trigger and involved for the outer javascript which called from the ajax's update panel web control.
How to allow the javascript can be run where it's call from inner update panel, for now its will cause the errors one the update panel's web control call the outside JS/countdown.js file as well....
i have an issue running JavaScript inside an updatepanel,
i'm using a script as follows:

outside an update panel this works, but inside the script doesn't run, i have read on other posts that there is an issue with running javascript inside an updatepanel.

View 2 RepliesI got XYZ page which got few divs inside of himin 1 of the divs there in an updatepaneland in another there are buttons which being inserted into the page using javascriptWhat I want to do is once a button is clicked, it would invoke a method using javascript in the server which would update the updatepanel
View 2 RepliesI 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 multiple update panels with various asp buttons on a single page. I want to disable the buttons which caused the postback in update panel untill it completes.
Is there a way to avoid using a third party control for this? through JQuery or any other method ?
i have a user control in which the cancel reset button clicks will call a javascript. this works fine when the user control is used normally...
if the usercontrol is put inside an update panel. the javascripts throw an error. "Object Excpected."
I have a user control.
On that user control is an update panel.
In that update panel is a wizard.
One of the steps is as follows.
[Code]....
What this does is create a javascript spinner control. Now when I click the NEXT button onto this step it generates the spinner control. I click next to go to the next step, then I click PREVIOUS to go back to this step and the spinner control is not generated.
Now I have tested this on an ASPX page and it seems to work, I then copy the code across to an ASCX control and put the page live and it does not work.
The update panel has an animation extender that just displays a div with a processing gif when you click next/previous.
So any reason why it creates the control on the next and not the previous step?
