  • django admin - adding fields on the fly

    - by Thomas
    Basically I am writing a simple shopping cart. Each item can have multiple prices. (i.e. shirts where each size is priced differently). I would like to have a single price field in my admin panel, where when the first price is entered, an additional price field pops up. However I am kind of at a loss as to how to do this. What would be the best way to do this?

    I'm building an Flex 4 application using IntelliJ IDEA generated sample Flex application. I replace the mxml with the following code from the book Hello Flex 4.

  • How can I have an mx:Window automatically resize to its content?

    - by Troy Gilbert
    I'm creating windows in a Flex application (AIR) using the mx:Window component. I'd like the window to be automatically sized to its content (because it will be dynamic), in the same way that an mx:Panel or mx:Box would be. I've customized components before, so I'm somewhat familiar with the UIComponent lifecycle, but I'm not quite sure how best to do the logic for auto-sizing a container. If it makes it easier, I'm not expecting that the window auto-size to its content at any time, thought that would be a bonus!

  • Online Flowchart Diagram Tool (run from private wiki)

    - by red.october
    Hi, Is there some flowchart diagram tool that would (or could be made to) integrate with a self-hosted wiki? Requirements: basic functionality (e.g., drawing some boxes and some arrows) would strongly prefer it to be visual (i.e., not written out in text that then gets converted) it is important that it can be integrated into the wiki (e.g., as an extra panel somewhere) can be run from a personal server free I've looked around at other threads here concerning a diagram tool, but they are either desktop applications, online ones which reside on third-party servers, or cost money.

  • resize ModalPopupExtender

    - by Joo Park
    after showing the ModalPopupExtender, there are two radio buttons that are displayed as part of the popup. When you select the second radio button, I display more information in a gridview control. When the ModalPopupExtender first displays, I have it set at 40% for width and height for the panel associated with the popup. After clicking the second radio button, I would like to resize the popup to 80% for width and height. My question is how do you resize ModalPopupExtender after it's initial popup?

    I have download and installed Visual Studio 2010 RC and I want to develop for the new Windows Phone 7. But when I run the vm_web.exe (that IS the name of the exe file, isn't it?), It still says that I haven't installed Silverlight 4.0 SDK, BUT I have installed the Silverlight SDK. In my control panel's menu, it says I have installed "Microsoft Silverlight 4 Beta SDK".

  • jQuery Dialog causing buttons not to post-back

    - by jonathanconway
    I'm using the jQuery UI Dialog() function on an ASP.NET webform, on a particular panel. After Dialog() is applied, the buttons become useless and will not post back at all; I'm not even getting a Page_Load event firing, let alone any button events. Is the Dialog function messing with my button events? If so, is there a way to fix this?

  • Duplicate System.Web.UI.AsyncPostBackTrigger Controls keep getting inserted automatically, causing P

    - by Albert
    I have an update panel with a number of [asp:AsyncPostBackTrigger...] controls, and everything was working fine. But now, something keeps inserting duplicate AsyncTriggers, and instead of simply being [asp:AsyncPostBackTrigger...] controls they're [System.Web.UI.AsyncPostBackTrigger...] controls, and I get parser errors as a result. So I delete the duplicate triggers, and they get re-inserted within a few minutes, seemingly randomly. Anyone know whats going on here?

  • Django: name of many to many items in the admin interface

    - by Adam
    I have a many to many field, which I'm displaying in the django admin panel. When I add multiple items, they all come up as "ASGGroup object" in the display selector. Instead, I want them to come up as whatever the ASGGroup.name field is set to. How do I do this? My models looks like: class Thing(Model): read_groups = ManyToManyField('ASGGroup', related_name="thing_read", blank=True) class ASGGroup(Model): name = CharField(max_length=63, null=True) But what I'm seeing the m2m widget display is:

  • Re-using Buttons in WPF

    - by Alex Marshall
    I have a bunch of different objects that are commonly edited in the same TabControl using different DataTemplates, but I want each DataTemplate to have a common look and feel with Ok and Cancel buttons at the bottom right of each tab that will close the tab or save the content and then close the currently selected tab. What's the best way to place buttons on each tab ? Is there a way to do it without copying and pasting the buttons and stack panel across all of my data templates ?

  • WinAPI magic and MONO runtime

    - by Luca
    I'm trying to get the same result of a .NET application (see the link Hide TabControl buttons to manage stacked Panel controls for details), but using the MONO runtime instead of the MS .NET runtime. Pratically, when the custom control is executed using the MONO runtime, the underlying message is not sent to the control, causing the tab pages to be shown... Is there a portable solution which is elegant as the linked one? If it is not possible, what are possible workarounds (apart from removing/adding tabs at runtime)?

  • Asp.net hosting equivalent of Dreamhost (pricing, features and support)

    - by Cherian
    Disclaimer: I have browsed http://stackoverflow.com/questions/tagged/asp.net+hosting and didn’t find anything quite similar in value to Dreamhost. One of the biggest impediments IMHO for developing web applications on asp.net is the cost of deployment. I am not talking about building sites like Stackoverflow.com or plentyoffish.com. This is about sites that are bigger than brochureware and smaller than ones that require dedicated servers. Let me give you an example. xmec.org is an asp.net site I maintain for my college alumni. On an average it’s slated to hit around 1000-1100 views per day. At present it’s hosted on godaddy. The service is so damn pathetic; I am using it only because of the lack of options. The site doesn’t scale (no, it’s not the code) and the web control panels are extremely slow. The money I pay doesn’t justify the service or the performance. Every deployment push is a visit to the infuriating web control panel to set the permissions and the root directories. Had I developed it in python, this would have been deployed on Dreamhost.com with $10/year hosting fees (they have offers running all throughout) 50 GB space 5 MySQL Databases Shell / FTP Users POP / SMTP Access Unlimited Domains hosting Unlimited Sub domains hosting Unlimited Domains Forwarded/Mirrored Custom DNS (These are the only ones I could think of. More at the feature page) With a dream host shell, I even have a svn checked-out version of wordpress for my blog. Now, that’s control! To my question: Is there any asp.net (preferably .net 3.5. Dreamhost keeps on updating versions every fortnight) hosting company providing remotely similar feature-sets and pricing like Dreamhost. My requirements are: Less than $15-25/ year Typical WISP minus PHP .net 3.5 SP1 Full Trust mode(I can live with medium trust, if not for the IL emitting libraries) Isolated Application Pool 5 – 10 MySQL db’s Unlimited domain hosting MsSql 2005 or 2008 FTP support At Least 5 GB space SMTP IIS 7 Log files Accessibility Moderately good control panel Scripting, shell support Nominal bandwidth Another case in point: Recently I’ve been contemplating building a tool-website to find duplicates and weird characters in my Google contacts and fix them. With asp.net, the best part is that I can do this with LINQ to XML in less than 100 lines of code. What’s bad is the hosting part. I don’t think I stand to make any money out of this and therefore can’t afford to host it on GoGrid or DiscountAsp.net. Godaddy is not an option either. If I do this in python, I can push to this my existing $10 Dreamhost account with another domain pointed. No extra cost. Svn exported with scripts (capability) to change the connection string! Looking at the problem holistically, I think I represent a large breed of programmers playing it cheap and experimenting different things on a regular basis, one of which will become the next twitter/digg.

  • How to get GridSplitter to move between extremes

    - by AKoran
    I have a Gridsplitter in a vertical grid and ideally what would like to see two buttons in the GridSplitter. An up button would automatically move the splitter to the highest top position and a bottom button would move it all the way down. However, the GridSplitter cannot contain other items. Any thoughts on a way around this? I thought of just making a panel and then sandwiching it between two GridSplitters?

  • Drawing A Piano

    - by Jonathan M.
    Hello Everyone, I have started working on a software synthesizer (or keyboard). I have decided to use Java because of the available Jfugue API. I am trying to figure out how to go about creating the actual keys (notes) of the keyboard user interface, but I am stuck. I have tried to create an interface by dragging/dropping black and white rectangular buttons onto the panel, but that doesn't seem to work. Could someone point me into the right direction?

    Is there a way to remove the LineShape shadow effect when selecting the lineShape? I tried Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs) Dim g As Graphics = e.Graphics g.SmoothingMode = SmoothingMode.AntiAlias Dim oldmode As SmoothingMode = g.SmoothingMode g.DrawLine(_Pen, X1, Y1, X2, Y2) g.SmoothingMode = oldmode End Sub but finally, this have some back effects on invalidation: when moving (in a panel) the line leave traces - does not invalidate properly.
