I cannot get the handle image to appear in my webpage using the ResizableControlExtender control in IE8 (comp. mode).
I have verified that the image path is correct. Here is my code:

I have made a solution with ResizableControlExtender in the Ajax control toolkit. It is a solution with a treeview on the left side of the screen and a content panel on the right side. Depending on what level in the treeview the user clicks at different content is shown in the right panel. What I want to do is to make it possible for the user to resize the width of the treeview. I have put the treeview in a panel and sets the target for the ResizableControlExtender to this panel. I have set the overflow style to auto. This works fine in all browsers except IE6. Unfortunately IE6 is an important browser for this solution. In IE6 the text of the treenodes is not cut when it is wider than the treeview width so it flows over the borders.The overflow works if I set a fixed width in the styleTreeView class but that makes it impossible to resize. I've tried to change the overflow setting in a lot of ways but nothing is working.

I couldn't figure out why ResizableControlExtender doesn't render using the handleCssClass , but it works fine on firefox. I I have follwing code.

This is really annoying me now!! I found a lot of references to this last night but none now :-(I am attempting to use the editor control in a 3.5 site created in VS 2010 beta and whilst the control is appearing and I can use and reference it fine in code I cannot get the popups to appear for love nor money.The pop ups that I am refering to are the ones that appear to choose colour or to add a link.I am using the latest ajax toolkit available for download from codeplex, as I said VS2010 and working on the 3.5 fw
View 2 RepliesI have added a ValidatorCallOutExtender to my code and the error msg appears fine BUT the background to the middle section of the extender is white (whereas the default is meant to be yellow. The little pointer arrow & the close button have the default yellow background but the main msg error appears white.
I then tried to change the background color through CSS but the same thing happened. I set the background color to blue but the main msg area appears with a white background whereas the little arrow & close button have the blue background. Here is my code:

I have strange behavior where comma appears on the text box each time I click pagination or button that causes page post back a comman is appended to the text box. Comma is appended in a incremental mode that is no. of commas is equal to the no. of times panel posts back.
View 2 RepliesI am saving an image file, then using Image namespace to resize the image.
The problem is that from the point of when image is saved to the system, to the point where image resizing is handled, the file handle seem not to get released right away, giving me error "A generic error occurred in GDI+"
Here is my code:
I am using asyncfileupload ajax control, C# in VS 2008

I have a follow-on question to How to display an image based on SelectedValue in a GridView?
What I would really like to do is have a ViewImage button on my GridView control so that when that is clicked, the image is displayed on a new page in a new browser window. How would I do that? I'm thinking perhaps do I need to create a
<asp:ButtonField>
How do I handle the click and how do I get the image to diplay on a new form in a new web browser window?
I have a bit of code in a clickevent handler like this:-
Dim products = From p In db.Products where p.product_name = "Tool" Select New With {p.Product_ID,p.Product_name}
Gridview1.Datasource = products
GridView1.Databind()
But causes error=SQL Server does not handle comparison of NText, Text, Xml, or Image data types?
where product_name field is set as type text

But it does not work. Image is like Previous. Note that ImageOperations.ResizeFromStream() method resizes and saves the image to a specefic folder. actually I should trigger a Postback to Update the Update Panel but How to do that. I usedUpdatePanelNew.Update(); but it does not work!

I need to know, how to add a validator in Ajax AsynFileUploader which will validate the image dimensions.
View 8 RepliesI am in the process of putting a new site together which will make use of AJAX to pull through page content should the user have javascript enabled.
So, I am in the situation whereby every Action Method requires a check to see if the request was through AJAX or not, which is straightforward. If the request was through AJAX then I can return a partialview, if not then a full view can be returned.
With this pattern though, I'll need to create a View and a PartialView for every page on the site. The only real difference between them is going to the inclusion of the masterpage.
Am I missing a trick here is is this doubling up of views the only way to go?
I had a page that could get accessed through /site/test. Somewhere in my JS I would add a hash to the url like so #/site/test. JS would then watch for any hash changes and load the partial views as needed. If JS was not available though, an entire view would need to be returned.
So for each page I would need the view, which would then include a call to RenderPartial which would load up the partial view which would actually contain the page content. So, for every page there are two files. It just seems there should be a cleaner way of doing this.
I handle unauthorized request with custom code. Problem is that after calling HandleUnauthorizedRequest method, Application_Error is called with Server.GetLastError() exception "Server cannot set content type after HTTP headers have been sent." .
I debug for a while and no clue. Here is my code.
When I debug the call stack is:
AuthorizeCore() -> HandleUnauthorizedRequest() -> Application_Error() -> javascript error in MicrosoftAjax.js

The requirement I have is to be able to have a popup form that shows detailed data on a facility. This would be available on various pages of the website where the user may want to drill down and see detailed information on a facility. We also want to allow the user to update the data on the facility if so desired. I have the code working to show the popup form and get the html for the popup from a view. Right now I'm setting the values of the input boxes using razor code that accesses the @model object. That's about as far as I've gotten.
Where I'm struggling is:
1. How to tie the data in the inputs back to the view model.
2. How to write the ajax code to write the data back to the server. I tried using a standard form, but that redirects the original page that popped up the form. I want to leave that page alone and just submit the data back to the server and close the popup.
Now my dev lead wants us to use the dojo toolkit for our javascript library. That would be OK if I already knew what I was doing with regard to web development, but I don't - and documentation is just not very good with regard to dojo. I'm still trying to figure out html and mvc, so I thought I'd see if I can get this scheme working with some other javascript library first, and then see about switching it over to dojo.
I've read some about knockout and jquery, but with everything being so new to me it's hard to get all this to gel in my head, and I'm not sure about my design. I've read some about mvc's built in ajax tools, but so far all I'm seeing is stuff related to getting data and displaying it - not about submitting data.
I'd like to be able to send the data back to the server in the same object structure that I extracted it with - something that matches the model. I think this is doable, but I'm not sure - and the 'how' of it is escaping me at this point.
i am having 2 imagebuttons a gridview and a button. Now if i clicked on Image button i will show a grid. Now under button click i would like to capture which image button was clicked if 1st image button is clicked i would like to some values and if 2nd one is clicked i would like to show another
View 2 RepliesI'm making an ajax call using jquery to an asp.net mvc controller action:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult GetWeek(string startDay) {
var daysOfWeek = CompanyUtility.GetWeek(User.Company.Id, startDay);
return Json(daysOfWeek);
}
When session times out, this call will fail, as the User object is stored in session. I created a custom authorize attribute in order to check if session was lost and redirect to the login page.
How do you handle ajax requests when user is not authenticated?
Someone enters the page, leaves room for an hour, returns, adds comment on the page that goes throuh ajax using jQuery ($.post). Since he is not authenticated, method return RedirectToRoute result (redirects to login page). What do you do with it? How do you handle it on client side and how do you handle it in controller?
I really want to switch over to ajax, but i can't seem to get my error handlling perfect. If i can't handle errors correctly, I just can't use it. What I really want to happen is to do a full refresh of the Top Frame. How I normally do this is by a similar call to Response.Write(<script>top.location.href = ""</script>). I was currently doing this in Global.asax. This becomes a problem when I error out in an AJAX postback. I've also noticed that There is an AsycPostbackErrorHandler you can attach to the ScriptManager. This is all find an dandy, but it will still hit my Global.asax Application_Error Event.
I am honestly just not sure how to handle this.
As I said, the result I want is....To Reload the Top Frame with some Error Message...whether I have to do some weird redirection or whatever. My problem lies specifically with the Global.asax file.
i'm using asp.net 2.0 form with ajax. i have an ihhtpmodule which can thrown an exception at Application_EndRequest step. my problem is that if this happen in an async postback (i mean a postback of an update panel) i can't manage the exception (with manage i mean set a custom error message server-side) becouse it's too late for the error handler of the ScriptManager.
(the alert will print a message as:
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near 'MyButt" />
|<html>
<head>)
at the moment my idea is to clear the response in the module and find a way to use the scriptmanager to send the correctly response of an error/exception. it's this possible? or samebody has another option of how to manage this case? note:i can't edit the aspx to manage this client client side with custom javascript
