  • How to clear all form fields from code-behind?

    - by Slauma
    HTML has an input button type to reset all fields in a form to their initial state in one step: <input type="reset" ... />. Is there a similar simple way to reset all form fields of an aspx page from code-behind? Or is it necessary to reset all controls one by one with TextBox1.Text=string.Empty, TextBox2.Text=string.Empty, etc. ? Thanks in advance!

  • Java Web Application on Tomcat - Displaying a File Uploaded by User

    - by walnutmon
    I need to display uploaded files on a web application, the flow is as follows User uploads file through web UI Validation on image Makes call to imageRepository.store( uploadedImage, user.getSite() ) The user wants the image displayed which adds <img src="${anUploadedImage.getUrl()}"/> but that is where I'm stuck, what can getUrl() do? The simple solution is to put it someplace and let Apache serve the file, but then I can't use the application to ensure that one user isn't modifying the URL to view other users files, which in this case is important

    - by sebastian_h
    Its common to observe listview developments for webforms but no common in mvc. on the other hand for mvc I´m only finding grid views displaying tabular data.

  • Business Logics on the client side

    - by Ivo Rossi
    Why do people say that business logics should be implemented on the server side code (e.g. EJB) and not on the client application code? The example that I have in mind is a business object validation on a EJB based architecture. Does it really have to be delegated to the EJB or is it ok to run it on the client before the object is sent to be server to be saved?

  • Where about should my main class be created in a project?

    - by Dan
    The problem is where a class should be created in my code. An example is I have a UI class and a main logic class that controls other objects. Should the main logic class create the UI object, or should the UI object create the instance of the main logic class? An explanation of which method is best and why would be ideal. Thanks.

  • [symfony] sfGuardDoctrine plugin and form messages

    - by David
    I'm using the sfGuardDoctrine plugin, and I would like to customize the form validation messages. How could I acomplish this? I can't find anything in the documentation. The only way I have found is to copy sfGuardValidatorUser.class into /apps/frontend/lib/validator, but I would like to know if there is some way to just override the error message, not override the entire validator...

  • Group by in Winforms/webforms DataGrid

    - by Kumar
    I'd like to implement the group by features for the default grid as it's available for the commercial grid like devexpress/infragistics et al, if you want a sample, see the 2nd image on http://www.devexpress.com/Products/NET/Controls/WinForms/Grid/dataoperations.xml I'd think there's some pattern or better yet some opensource/free grid which does this already, if not, i would probably implement it if i can find the time (doubtful ! and esp since it's available so easily in most packages, if only i can convince the client to pay for a license ) & want to get some ideas/patterns on the same

  • Android Custom PopWindow/Dialog

    - by Kilnr
    I'm trying to get a completely custom Dialog or PopupWindow, without any of the default Android UI controls (title, background, buttons, whatever). Is this possible at all? I've spent hours searching for this, but no luck... It seems like this should be easily possible, but I can't find it. Preferably this would be by inflating a View from XML, but at this point anything that would just work would be nice. Thanks.

  • AutoScaleMode.Inherit does not inherit

    - by codymanix
    I have a user control contained in a tabpage. The Form has set AutoScaleMode = AutoScaleMode.Font and the UserControl has set AutoScaleMode.Inherit. Now when I enlarge the font size of the form then the font is enlarged in the user control too, but the controls contents are not scaled. If I explicitly set AutoScaleMode.Font on the user control then it works properly. Shouldn't AutoScaleMode.Inherit work that way?
