I am just starting to study ASP.NET from my WPF Knowledge. I think the UI designing is very difficult in ASP.NET compared to WPF XAML design.
I have a problem in my UI layout. In WPF we use Width=" * " and Height=" * " to adjust height and width of the controls like listview, listbox so that the application can run in any resolution without overlapping ? What is the alternate way to set height and width in ASP.NET?
Ideally you'll want to be setting the style's of your controlls using CSS.
If you have a control that has a CssClass="myControl" then in your CSS you'll be able to do the following:
.myControl{
width: *px;
height:*px;
}
Where * is a numerical value. You can also change the value type from px to % and other value types.
Using a % value type will allow you to cater for multiple resolutions whilst retaining a similar feel to your application.
Use '%' for specifying height and width.
Specified as a of
containing block's width.

I have 3 subviews(UILabel, UIImageview, UIButton) to be laid out on a container view. All the subviews are laid out using visual format language (VFL). The subview have padding from the leading , top edges etc. The content of the subview are dynamic so their sizes changes all the time. i want to resize the superview(container view) to exactly fit all the subviews. Is this possible by auto layout? i have seen some of the link here which suggest intrinsic size which i am not able to understand. can someone suggest a better way to achieve this.
Yes, it's possible. If you plan to resize the superview according to subview content, then intrinsic content size is the way to go.
The ever excellent Ray Wenderlich site has a tutorial that covers this well. It's Beginning Auto Layout in iOS 6: Part 2/2:
Intrinsic Content Size
Before Auto Layout, you always had to tell buttons and other controls
how big they should be, either by setting their frame or bounds
properties or by resizing them in Interface Builder. But it turns out
that most controls are perfectly capable of determining how much space
they need, based on their content.
A label knows how wide and tall it is because it knows the length of
the text that has been set on it, as well as the font size for that
text. Likewise for a button, which might combine the text with a
background image and some padding for the rounded corners.
The same is true for segmented controls, progress bars, and most other
controls, although some may only have a predetermined height but an
unknown width.
This is known as the intrinsic content size, and it is an important
concept in Auto Layout. You have already seen it in action with the
buttons. Auto Layout asks your controls how big they need to be and
lays out the screen based on that information.
It is possible.
In my case, I wanted to give rounded corners to segmented control. For that, I embedded segmented control in UIView. Now I was required to resize that container view as per size of segmented control.
I gave only following constraint and everything was taken care itself.
(1) Chose container view and give it X and Y constraints.
Leading space to Super view.
Top space to Super view.
(2) Chose container view and give Leading | Trailing | Top | Bottom constraint.
Leading space to segmented control.
Top space to segmented control.
Trailing space to segmented control.
Bottom space to segmented control.
(3) Chose segmented control and give it Height and Width constraints.
Height : 30 // Whatever
Width : 250 // Whatever
Now if I change the height and width of my segmented control, it automatically adjust container view's size (super-view of segmented control).
I am quite new to ASP.NET development so I am unsure of how to do this without hardcoding the value.
To make the ASPxGridView to occupy a container space by width, set the control's Width property to 100%. This trick won't work for the height. Please note, the ASPxGridView is an XHTML compatible control and this standard does not support setting the height property yo 100%. Also, I should tell you that usually the grid's height is defined by its content. I.e. if you are planning to show 10 records per page, the grid's height will be identified by the height of these 10 rows + height of the column headers pane, height of the pager and other elements (footer, group panel...). If you want to set the control's height directly, I would suggest that you activate the vertical scrollbar (Settings.ShowVerticalScrollbar = true and specify the Settings.VerticallScrollableHeight property. This property will allow you to define the height of the of the scrollable part (rows). I hope, this information will be helpful to you.
I am working on an Adobe AIR Application. The size on Application window is 800X600 and is contains border container and border container contains many controls.
What I want is to if user re-sizes the application then that container should also be re-sized according to scale. i.e If user maximizes or minimizes the window then that border container should also be maximized or minimized respectively.
If you don't want to (or can't for some reason) use percentage based widths then you can always just do the following in MXML:
<s:BorderContainer
xmlns:mx = "http://www.adobe.com/2006/mxml"
xmlns:s = "library://ns.adobe.com/flex/spark"
width = "{parentApplication.width / 2}"
height = "{parentApplication.height / 2}">
You are just getting a reference to the component's parentApplication and directly binding to its width and height. Throw whatever math you want on the end.
An easier way to do this is to have your components declare their sizes/positions relative to their outer containers. For example, rather than setting x, y, width and height, set left, right, top and bottom in your Application component as well as the containers within your Application. If you want to enforce a minimum size of 800x600, you can set the minWidth and minHeight properties. Hope that helps.
This can be accomplished using an MVC framework. Some options include RobotLegs, Mate, Cairngorm or it is possible to use some quick design patterns and implement a custom version.
Essentially, the Application event Event.RESIZE should be detected and applied to the container. The properties of stageHeight and stageWidth will give the necessary info to resize the container.
Resize events will traverse the display hierarchy in any case, but it's convenient to intercept at the application level, should a custom event or function apply to the controls.
I am working on a flex app that uses XML templates to dynamically create DisplayObjects. These templates define different layouts that can be used for each page of content in the app (ie , 2 columns, 3 columns etc etc). The administrator can select from one of these and populate each area with their content.
The templates add one of 3 types of DisplayObject - HBox, VBox or a third component - LibraryContentContainer (an mxml component that is defined as part of the app) - which is effectively a canvas element with a TextArea inside.
The problem that I am getting is that I need each of these areas to automatically resize to fit the length of the content but don't seem to be able to find an effective way to do so.
In the LibraryContentContainer, when the value of the TextArea is set, I am calling .validateNow() on the LibraryContentContainer. I then set the height property on both the TextArea and LibraryContentContainer to match the textHeight property of the TextArea.
In the following example, this is the LibraryContentContainer, viewer is the TextArea and the value property of the TextArea is bound to this.__Value. v is the variable containing the content for the textarea
this.__Value = v;
this.validateNow();
this.viewer.height = this.viewer.textHeight;
this.height = this.viewer.height;
This works to a degree in that the TextArea grows or shrinks depending on the length of content, but it's still not great - sometimes there are still vertical scrollbars even tho the size of the TextArea has grown.
Anyone got any ideas?
Thanks
Adam
I think the problem lies not with your dynamically added components, but with the component they're being added to. How is the height of this component being determined? If you set verticalScrollPolicy and horizontalScrollPolicy on this container to off, do your scrollbars disappear? If that's the case, then you'll need to look at how this component is sized rather than your hbox, vbox, or whatever it is you're adding.
I have used 960gs to get a first version of some pages going (I am not the designer, but would like to have an approximate layout before handing it to one). It has helped me greatly, but now I am wondering if there is a CSS grid framework where the columns will expand/shrink to make use of all available space in the browser window. Using a 960 pixel top-level container in 960gs, even in my humble 1280-pixel-wide screen there are large empty bands on both sides.
Are there alternative grid systems where I can define a certain column to "grow" if the browser window is larger than expected?
Many thanks!

There is a Fluid 960 Grid System too.
See this ala article on fluid grids and example. Also see this example.
I'd use Unsemantic it's from Nathan Smith who developed 960.gs.
Either that, or you can customize Twitter Bootstrap so that you only take the responsive grid and leave out all the other features that might be unnecessary for your project.
Try the Dead Simple Grid. You can set the columns to have fixed or percentage widths. Setting to percent will dynamically fill the available space. It is very simple (the entire css code is 250 bytes!) but surprisingly powerful.
Cascade Framework's grid system can do exactly what you want... and lots, lots more.
If you use the tag <div class='site-center'></div>, you get a centered div with a fixed width for desktop (width is different depending on browser width) and the full available width for mobile. You can, however, just drop that tag and use the full available width on desktop as well. See this website as an example of an implementation thereof.
The grid elements themselves are percentage based. That means that they fill up a certain percentage of the available width. Out of the box, Cascade Framework's grid system supports 60%/40%, 25%/75%, 33.33%/66.66%, 20%/20%/20%/20%/20%, 43.75%/31.25%/25%, 30%/30%/40% and far more combinations. In fact, you can even use combinations like 42.8571429%/{fill to 100%}, {fit content}/{fill to 100%} or {fit content}/30%/{fill to 100%}.
To be able to use Cascade Framework's grid system, I recommend you use either the file 'build-full.min.css' (about 8kb minified + gzipped) or the file 'build-full-no-icons.min.css' (about 10.8kb minified + gzipped) in the folder 'assets/css/cascade/production, depending on whether you want to include support for its icon set. You can also create your own build and pick only the modules you want. For the sake of brevity, I'm skipping details on how to do that. If anything isn't clear about creating your own build and you'd like to know more about this, please send me a PM to avoid derailing this thread by going too far off-topic.
A grid element in Cascade framework is either
One of the following HTML elements : section, main, article, header, footer, aside or nav (these elements are polyfilled with the HTMLshiv for old IE in case you need it).
A div element with a 'col' class (can be used in old IE without a polyfill).
To add a width to a grid element, you add a class of the format 'width-XofY', where Y can be 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 16 or 24 and X can be any value lower than X.
More concretely, here are some examples of valid classes you can use in Cascade Framework : 'width-1of2' (width : 50%), 'width-3of4' (width : 25%), 'width-2of5' (width : 40%), 'width-2of5' (width : 40%), 'width-2of7' (width:28.5714286%) and 'width-13of16' (width:81.25%)
Additional to these classes, you can also use the classes 'width-fit' and 'width-fill' that respectively fit to content and fill whatever remains of your 100% width. Or, you could just define your own classes and IDs and just add a custom width for those classes to do things the 'semantic' way.
If your builds include the responsiveness module (which is the case for the recommended builds), the width of all grid elements automatic resets to 100% on mobile. You can use classes like 'mobile-width-3of16', 'phone-width-3of7' or 'tablet-width-2of4' to customize the layout for different width ranges and the classes 'desktop-hidden', 'mobile-hidden', 'phone-hidden' or 'tablet-hidden' to hide content for a specific screen with range.
