View 5 RepliesLogin Page Cannot Load An Image Because The Request Is Redirected?
Nov 30, 2010I had a website project which worked fine. I have converted it into a web application project in VS 2010. Now when I start the project from VS my login page is never loaded because when it tries to load images, scripts, css all the requests are redirected back to login page.
However if I setup a website under my local IIS to use the folder where the project is the website works no problem.
I have created a test web app to play with. And it does pretty much the same. Login page cannot load an image because the request is redirected. Here is what I've got.

View 6 RepliesMultiple File Inputs / When Post Back Request Files Collection Is Always Empty?
Jan 5, 2011I am using Asp.net and requirement specifies i use html input to post files to server rather than asp:fileupload.[ Reason : Add more html input file controls similar to CPanel file manager.(i.e) clicking on link adds another file input from which user can select another file*.But when ever i post back Request Files collection is always empty.*
HTML FORM:
<form method="post" enctype="multipart/form-data" action="documents.aspx">
<div>
<input type="file" name="attachment" id="attachment" onchange="validate(this)" />
<span class="none">Filename should be within (1-25) letters long. Can Contain only letters
& numbers</span>
<div id="moreUploads">
</div>
<div id="moreUploadsLink" style="display: none;">
<a href="javascript:addFileInput();">Attach another File</a></div>
<input type="submit" id="btnSubmit" />
</div>
</form>
Javascript:
var upload_number = 2;function addFileInput() {
try {
var fileUpload = document.getElementById("attachment");
var elemSpan = nextElement(fileUpload).cloneNode(true);
var elemDiv = document.getElementById("moreUploads");
var d = document.createElement("div");
var file = document.createElement("input");
file.setAttribute("type", "file");
file.setAttribute("id", "attachment" + upload_number);
file.setAttribute("onchange", "validate(this)");
d.appendChild(file);
d.appendChild(elemSpan);
elemDiv.appendChild(d);
upload_number++;
} catch (err) { alert(err);}}
the validate(this) is a function that validates file types on client.When validation succeeds then the link to add more file inputs is enabled. Could someone throw somelight on this.
Ajax - Load User Control And Handle Post Back?
Feb 10, 2011I'm working with asp.net 3.5 c#
I've seen a good few questions like this around but havnt actually come across any articles with the answer (maybe just been unlucky with my research!).
Basically I'm looking to have say 3 links (or buttons) on a page, which in turn will dynamically load a specific user control into an update panel with AJAX.
Then I would like the usercontrol loaded to be capable of handling postback within the update panel (basically no page refreshes) to do its processing and return output.
Does anyone have any pointers to articles/blogs covering this?
I've seen many but non covered handling postbacks from the user control or handling the postbacks within the update panel.
C# - Using A Timer Post Back, Which Controller To Use That Doesn't Post Back To Server?
Jul 14, 2010Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

AJAX :: Dynamic Image Buttons In GridView Not Doing Partial Post Back?
Sep 9, 2010watch here:
- Create a gridview with AllowPaging and AllowSorting = true
- On page load, I bind it to datasource (in my case a webservice)
- On gridview's rowcreated event, I dynamically add image buttons on the header of the grid for sorting (up/down arrows). On header I have column name and the image. I removed the Column name default sorting link. So user can now only click the image button for sorting.
- Call sorting method
This works perfectly fine without AJAX. The paging, sorting works fine. Also when I apply AJAX the paging works fine. But the sorting is doing a full post back instead of partial postback.
I have my gridview within UpdatePanel and Triggeres is set on gridview sill it doesn't work.

View 4 RepliesWeb Forms :: Position Page At Bottom After Post Back Ignoring Focus() Further Up Page?
Jun 7, 2010I have a page that I am adding user controls to the bottom of the controls each postback. The User Control has a textbox in it and the focus needs to be on this newly created control textbox each time. It all works almost perfectly however when there are too many controls to fit on the page, because I set the focus to the textbox the bottom of the page is set to the textbox that has focus not the very bottom of the page. I have a submit button below this which ends up below the page limit. How can I set focus to a textbox but still scroll to the every bottom of the page to show the submit button.

C# - Page Enter Key Causing Post Back?
Nov 17, 2010I have an aspx page that postsback when it should not. there are two text boxes, two listboxes and two buttons on the page. if at any-point the enter key is pressed the first button is given focus and "clicked" resulting in a loss of selection within the listboxes.
How do I disable this? there are tons of tutorials on how to capture the enter button and execute a method but I could find one on how to simply disable the neat "let me grab the first button I find and click it" feature mentioned above.

View 3 RepliesWeb Forms :: Additional Post Back After Page Has Loaded?
Aug 4, 2010I am writting an application that displays 3 visable text boxes and 1 hidden text box and one hidden button.
My application sets focus to the hidden text box.
The input comes from a barcode scanning gun which gives the "enter" command after the scan is complete...this essentially clicks the hidden submit button which moves the text from the hidden text box to the currently active visable text box.
To start the application does some verification on what was scanned then gives the user feedback on what was scanned then enters it into SQL.
My problem comes with the last scan...the page does not actually post back to give the user the neccessary confirmation before commiting the info to SQL and resetting the form.
Is there a way to either do somethig after the page has been rendered or do an additional post back somehow before calling the commit and reset functions?
