I know that UpdateProgress doesn't work with PostBackTrigger, but let me explain what i'm trying:
I'm generating a PDF document (Crystal Report) with ExportToHttpResponse that will be downloaded automaticaly by the browser.
So while the document is been generated, i'd like to show the UpdateProgress just while i'm waiting the doc is being generated, doing the UpdateProgress(or some label) to disappear.
I have an button ("export") to export data from grid to excel.
But it's inside an update panel. So I'm registering postback trigger.
What should I assign to PostBackTrigger.ControlId ???
I Have a UpdateProgress in my page. I have a button that save and show a alert message if a condition is true.
The problem is that If I use the UpdatePanel+UpdateProgress my alert does not show, if I remove the UpdatePanel+UpdateProgress from my page, the alert is display!
[Code]....
</ContentTemplate
</asp:UpdatePanel>
</asp:Content>

I have a webform that works the following way:
1. Button_openPanel will display panel Step2Panel through ModalPopupExtenderStep2.
2. Button_runThread (inside Step2Panel) will close Step2Panel and will then run a lengthy process server-side. This lengthy server-side process will cause the UpdateProgress control to be displayed.
Similar to the ModalPopup, I want to disable the whole page while the UpdateProgress control (with its animation gif) is running. Currently, the UpdateProgress is displayed, but I can click Button_openPanel (or anything else) which will cause the application to break.
Is this possible?
This is basically all the code. I stripped anything that was unneeded:
[Code]....
The code-behind is basically this:
[Code]....
Everything's working pretty good now, but I need to disable everything while the time-consuming process is running and UpdateProgress is displayed.
I was thinking of displaying the UpdateProgress control as a a sort of ModalPopup, but I'm not sure if it's possible. If not, then the alternative would be to disable Button_openPanel while the time-consuming process is running and UpdateProgress is displayed.
i'm trying to make this work for several days but it just doesn't work.
this is my code:
aspx page:
[Code]....
webservice:

this was downloaded from this website.
the problem is that the page loads fine but no autocomplete occurs.
I am a new to WCF. I have written ajax to use a web service before, but on this project I am trying to use ajax to WCF.After I build the project and wcf using ajax, I receive the return successfully. But, 10 or more minutes later I don't get a return, the ajax calls the error function, and the fiddler returns nothing.
If I rebuild the project without any source modifying, I receive the return successfully again.
What is the different between AsyncPostBackTrigger & PostBackTrigger really?
View 2 Repliesi need to add the PostackTrigger for the ContentPage Button Control. The update Panel in Master PAge
The Button Control in Content Page how to add PostBackTrigger for ContentPage Button Control
In my UpdatePanel, the user can page, sort and filter a gridview all using AJAX, then they select a row which causes the post to post back and a textbox to be populated with the rows ID.
Problem is, it seems I can't register both an AsyncPostBackTrigger and a PostBackTrigger to the same control - so how would I accomplish this? Here are my triggers so far:
[code]....
In documentation I have read:
„Use the PostBackTrigger control to enable controls inside an UpdatePanel to cause a postback instead of performing an asynchronous postback."
I made simple application and I do not see difference between using PostBackTrigger and standard postback.
I have three buttons: two inside update panel and one outside update panel. When I click btnUpdateAsync in event handler I set text property of lblUpdatePanel and lblNoUpdatePanel and only lbl that is inside update panel is chaned if web browswer - so this is ok.
Whant I click btnUpdateInUpdatePanelSync all page is refreshed and both lablels are changed in web browser.
When I click btnUpdateOutsideUpdatePanel I see the same behavior.
If I used button that is not associated with PostBackTrigger I would get the same behavior - so what is the purpose of PostBackTrigger?
This is my app:
[Code]....
protected void Page_Load(object sender, EventArgs e)
{
}
protected void LinkButton1_Click(object sender, EventArgs e)
{
}
protected void btnUpdateAsync_Click(object sender, EventArgs e)
{
lblUpdatePanel.Text = "btnUpdateAsync_Click";
lblNoUpdatePanel.Text = "btnUpdateAsync_Click";
}
protected void btnUpdateInUpdatePanelSync_Click(object sender, EventArgs e)
{
lblUpdatePanel.Text = "btnUpdateInUpdatePanelSync_Click";
lblNoUpdatePanel.Text = "btnUpdateInUpdatePanelSync_Click";
}
protected void btnUpdateOutsideUpdatePanel_Click(object sender, EventArgs e)
{
lblUpdatePanel.Text = "btnUpdateInUpdatePanelSync_Click";
lblNoUpdatePanel.Text = "btnUpdateInUpdatePanelSync_Click";
}
On a page for new users to register, I've placed a asp:wizard control in a updatepanel.Everything is working great, but now I want a new user to upload an image. This however requires a full postback.Is there any way to define the finishbutton of the wizard as a postbacktrigger while the next and previousbuttons remain asynchpostbacktriggers?
View 1 RepliesI am trying to save an updated xml file to a url like this:

//save the output to a file
xmlDoc.Save("http://www.example.com/HomeNewsLinks.xml");
But I get this error: URI formats are not supported.
Did some google search on this and it seems I need to use client.uploadFile method, but I am not able to find how to declare/define filenamexxx (below) and how to pass a username/password.

WebClient Client = new WebClient();

I used this,

I am following though the examples in Professional ASP.Net MVC 2 and one of the examples doesn't work for me.
[HttpPost]
public ActionResult Edit (int id, FormCollection collection)
{
Dinner dinner = dinnerRepository.GetDinner(id);
if (TryUpdateModel(dinner))
{
dinnerRepository.Save();
return RedirectToAction("Details", new { id = dinner.DinnerID });
}
return View(new DinnerFormViewModel(dinner));
}
I understand that it's suppose to take the values from the FormCollection, and then update the dinner object with it, bit I don't see the collection get referenced anywhere.
I have div which it is hidden by default , when the use clicks show link the following javascript method is called:
function ChangeControlVisibility(elementID) {
var element = $("#" + elementID);
if (element.css('display') != 'block' && element.css('display') != 'table') {
element.show();
[code]....
this step works but when i call the previous method at page_load event the method doesn't work:
element.css('display') undefined.
[Code]....
And in default.aspx, the code is
[Code]....
But it is not working, the error is at alert(BiblePeopleArray(0));
In updatepanel we can use triggers with two methods AsyncPostBackTrigger and PostBackTrigger so I want to know what is different between these two as well how can we decide we need to go for which one.

I have a listview in which I use a pager control. When I have more than 1 item in the list view, I want the user to be able to click on the appropriate page number and go to it. Simple right?, right now the first time the user clicks on the page number, nothing changes. If they click on it again, it goes right to the page. It doesn't matter what page they click on, it ALWAYS requires a second click to display the data item.

I've been trying to fix something on a secure website (https) which is an Export to Excel button that generates a CSV file. It works on Firefox, Chrome , etc... but not in Internet Explorer. I have changed the headers eliminating the no-cache and also edited the IIS http header configuration setting an expiration date of 1 day. I have no idea of what can be going on and how to solve it. Do you guys have any idea of how to fix this stuff ? I've read so many posts and they're all saying the same thing... caching.
UPDATE 1 :
regarding the error I receive, I receive an IE Alert saying "Internet explorer cannot download filename.aspx from [URL]Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. As I said, it all works out of SSL (https), but the export to excel button, breaks in https.
UPDATE 2:
I'm using these headers:
Response.ClearContent();
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment; filename=" + name.Trim() + ".csv");
Response.AddHeader("Cache-Control", "no-cache");
Response.AddHeader("Pragma", "public");
Response.AddHeader("Content-Transfer-Encoding", "binary");
Response.AddHeader("Content-Length", "2026");
Response.Charset = "";
//Response.ContentType = "application/vnd.ms-excel";
Response.ContentType = "text/csv";
i've log-in page in my site but log-in control doesn't work on any browser other than IE.
