Here is the code of my Ajax Toolkit AsyncFileUploader which I have added in my ASP.Net(C#) web application.

public void afuUpload_UploadedComplete(object sender, AsyncFileUploadEventArgs e)
I'm hoping that somebody cleverer than I am can explain what's happening with my file uploading and how to improve it.My website is used by vets to submit photographs of tumours in horses for examination by another vet and so it's important that the pictures uploaded are high quality, and therefore the file size is large. Since they might be uploading details of several tumours at a time with several photos of each uploading times can be very long.
I accept that upload speeds are generally slower than download speeds and I have put notes on the page to advise the user to be patient while the images upload. However, I've noticed when using Google Chrome, which displays a percentage-complete in the status bar when files are being uploaded that what seems to happen is that when the user selects a picture from the asyncfileupload control it then slowly counts to 100% as the image is uploaded. But when they then click on the 'Save' button which is when code-behind uploads the file to the web server and writes an entry in the database it again counts to 100% at the same, slow speed.
It's as if the file is being uploaded twice. It's as if the file is being uploaded twice, but I've only coded it to happen once, when the 'Save' button is pressed. The first upload must be some part of the way the asyncfileupload control works. So am I using it incorrectly? Should I somehow be using the inbuilt, automated upload to get the image to my server rather than in the code-behind of the 'Save' button?
One other piece of information which may be relevant is that at the point the picture is uploaded by the asyncfileupload control there is no associated record in the database for it to be linked to. When the 'Save' button is clicked a record for that tumour is created first, then then the image(s) is uploaded and an associated record created with the image filename, so using the automated uploading of the asyncfileupload control may not be possible for me as at that point there is no record to link the filename to. If that's the case can I disable it somehow?
Ajax AsyncFileUploader is appreaing very bad in my ASP.Net(C#) web app.
Another very annoying thig is that; when its style is set to modren it does not show that grey image with the text "Select File" in any of the browser except IE 7.
While with "Tradition Style" the height of this control looks so squeezed in both IE 7 & IE 8 , And Is there any way so that we can change the style of that Browser button like the other buttons on out site and can we apply textbox skin on the uploader to it can shape like a textbox?
I need to know, how to add a validator in Ajax AsynFileUploader which will validate the image dimensions.

After the implementation of ajax drag and drop, we have observed that which is working fine in IE and Firefox and not in chrome and safari, In Google chrome and Safari when we try to drag a module, the page getting scrolling to the top of the page.

In the upper code... AutCompleteExtender1 works perfectly... AutoCompleteExtender2 not working at all. Same web service, same method... both are inside the same .aspx file... both have exactly the same conditions.What is it that I am missing? And if you think that it is because they both calling the same service and method it is not... the second doesn't work with different service or different method (both inside the same service and in the different .asmx file).Can it be, that you simply can't have 2 ACE controls on the same page?And btw, is it possible to run server code once someone selects something from ACE control?
Ajax calendar control not working properly with content place holder of Master Page.Most of time Calender Control hides when mouseover with out changing date in content place holder of Master Page.same code works in normal aspx pages.
View 2 RepliesI am new to Ajax Control Toolkit, with the help of online tutorials I had created a cascading dropdown list in asp.net and tested it on my local machine. For this dropdown list data source would be an xml file (which is saved on my local machine c drive). I haven't encountered any issues until I deploy the precompiled web site on to IIS 7. When I open the web site from IIS I would see the two dropdown boxes on the web page with an error "Method error 500". I believe this error occured due to incorrect xml file
path provided on IIS. I had copied xml and xsd files into IIS server C drive but it did not help out and then I created a network map and placed the xml and xsd files in that shared folder tried to access that path from web service, it's working on local machine but not on IIS. It would be great, if any one could explain me the solution.
Following is the .aspx and .asmx code:
.aspx code:

I got a new computer with vs2008 and moved my app onto it for development. I can navigate pages but none of the AJAX is working. I get these IE errors "sys is undefined" and "webpartmanager" is undefined. I found lots of info on the web but none seemed to work/be applicable to my situation. My web.config file looks to be fine and I kept the application at asp.net 2.0.

I'm using VS2005.I just downloaded .NET framework 4 and so then I downloaded ajaxcontroltoolkit.binary.net4 via [http://ajaxcontroltoolkit.codeplex.com/releases/view/43475](as opposed to ajaxcontroltoolkit.binary.net35 for .NET 3.5), but when I try to load the ajaxcontroltoolkit.dll into my toolbox (as said in the tutorials), I get the following error msg:"'C:......ajaxcontroltoolkit.dll' is not a microsoft .NET module."
View 2 RepliesBefore I use magic ajax, it was not a problem that if it's not ajax call, I can perform document.getElementById("button1").click();
However, in asp.net ajax extension, I can not do this and it reports a run time ajax error:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
What happens is, in my code, I have a facility to check if the user change any data they just input every 5 minutes. If yes, I will do a save function without notifying the user. and all the things are done on client side. So I have to use javascript, however, I could not user button.click() on js anymore.Is there any other way to call a server side function (code behind) by javascript?

I tried the basic example for adding AJAX extenders, namely opening a web form, adding Script Manager, adding a button, dragging the ConfirmButtonExtender on top of the button, and adding ConfirmText for the question, then hitting Ctl + F5, clicking the button.

In theory, my textbox should have an autocomplete dropdown containing 3 instances of the word "test". In practice, I can type anything I want into the textbox and nothing happens.
I am using VS 2005 with ajax extensions. I want to load data in a details view when drop down lists selectedindexchange event fires. This is not happening. The details view is in updatepanel and dropdown list is outside the update panel. I have also set the trigger control id and event name.The same thing is working with button control.

I have a simple aspx page created using VS2010, having a master and a content page. I have added the ScriptManager from AJAXControlToolkit on the master page and an update panel on the content page. Essentially clicking a link button should display a popup box through the PopupControlExtender. The issue I am facing is that eventhough I have AJAXified the page, clicking the Linkbutton (named lnkFlag) doesn't do partial update, instead it makes full page postback. This could be infered by the fact that both the lblOut and lblIn labels are updated with the server's time. If there is a partial page postback then lblOut should not be updated, since it is outside the UpdatePanel.

I am new using AJAX Controls. I have downloaded the tool kit, added it to my tool box in .NET, created a web application with a simple standar button and added a confirmation extender but the page only shows the button when I click on the button it doesnt show the confirmation box.I dont have any error, I have added the script manager to my page so not error at all.
