I have integrated QLPreviewController and UIDocumentInteractionController in my app, and it is working fine.
The only problem is- I want to configure the bottom toolbar, I want to remove the default toolbar items, which appear as shown in image below:
Is there any way to do so, please suggest.
Short Answer: NO, Not in IOS6+
Description:
One thing to note about QLPreviewController is that it's not meant to be customized. There were other libraries allowing you to change the functionality such as:
https://github.com/rob-brown/RBFilePreviewer
Which are not working in iOS 6+ since apple made a big change in QLPreviewController and it's technically running in a separate process. Although it might be possible (not sure) using private apis but your app will be rejected then.
You can find more info about this change here:

Hope this helps
Subclass UIToolbar
Create UINavigationController using
init(navigationBarClass:toolbarClass:) and supply UIToolbar subsclass created in step 1 for toolbarClass
Create QLPreviewController instance and push onto UINavigationController stack
Inside of UIToolbar subsclass override
setItems(_:animated:). To remove all buttons call super with empty array super.setItems([], animated: false) or potentially you can add only buttons you want to keep.
Present UINavigationController created in step 2
Here is the example PreviewControllerHideBottomButtons
Subclass QLPreviewController.
Search for the Toolbar in the view hierarchy.
Have a UIToolbar property in your class that has the same frame as the original toolbar.
Place your own toolbar above the default one with whatever buttons you want.
If you want it to be hidden as the default behavior of the QLPreviewController you can key value observe the hidden property of the default toolbar and present / hide your own accordingly.

I have created an instance of ButtonGroup and associated that to two RadioButtons. The RadioButtons are added to a Container and the Container added to a Form screen. When the "Back" button is pressed, I want to clear the ButtonGroup selection and reset certain variable instances.
I want to place the code in the ActionListener I have made for the "Back" function. My question is how to retrieve the reference of the ButtonGroup in order to clearSelection()?
Generally we recommend recreating the Form instead of caching it if you intend to "reset it" so I'd avoid this.
If you still want to go in this direction check out getButtonGroup() in RadioButton. You can also set a new group with the setter method.
You can use setUnselectAllowed(true) then invoke setSelected(false) on both buttons. Then restore default selection behavior using setUnselectAllowed(false).
While looking at animateLayout() method of ComponentSelector for another issue that I had, I realized that I may use this Class to obtain Component object references jQuery style elegantly. Very powerful and useful concept for codename one.
should adding or removing components trigger a repaint?
I have a prism application already in production.
I need to create a new module in this application.The module can either exist on not exist in the application depending on the configuration file.
This module view should be dispalyed in a region already existing. The view should only be visible when the module is loaded.
Problem: the existing screen has a region showing 2 tab items from 2 different modules. Now the new view should be part of the first tab and it gives the user the option to select whether to view the previous info or the new info from this new module.
I am stuck and dont know how I am going to show these checkboxes when the new module is loaded and hide it when it is not. Where do I put this logic?
Current scenario:
Very vague images to define what i meant?
Here's an option that will work, and isn't too much effort...
Inside your beautifully illustrated Tab1, add another tab control, and make this a Prism region. Fill this region with both the original view, and the view from your new module.
Then, restyle the inner tab control, if necessary, so the tab headers appear like radio buttons, and set up a datatrigger to hide the tab header strip if the number if tabs is less than or equal to 1.
Thanks for all your help :)
After a lot of RND i figure it out.
I have created a two tabcontrol regions one for the main tab and the other for the child tab.
on the child tab i have return style to display tabitem only if item.count is more then 1 as suggested by mark.
and i have put this code in my existing module.
Like the title said,how may i turn the grid(or page) and the components in it into background gray and unable and show a new component in foreground.
It's a common effect in the web page,but i cannot do that with a xaml.
Please answer in detail better with sample code if you do.Thanks in advance.
Here's an example of using a Popup to display a UserControl when a Page is navigated to. The OnNavigatedTo function creates a popup, binds a Click event to the UserControl, and then shows the UserControl over the entire page. If the correct password is entered, ("password" in the example) the control disappears. You'll need to modify it for your own requirements, but it should definitely get you started.

You'll want to use the VisualStateManager and create some animation transitions to switch between the old and new components. I won't paste the code here for brevity, but if you check out:
http://visualstudiomagazine.com/articles/2011/07/22/wcmob_visual-states.aspx
You'll see a simple example of switching between two UI components on a single page within a Windows Phone 7 PhoneApplicationPage. In your scenario, you'd use this paradigm to create 2 animation storyboards, one for showing an overlay control and one for settings the 'disabled' property on the main grid.
Adding a new Form in the project creates a default form with default properties. I have to change them manually, but in all my project I have the same properties (font, background color, etc.).
Is there a way I can change the default Ide template for Forms?
Not using inheritance as Adrian recommended is a mistake. It is the right way to do it because you can in one fell swoop change every form in your app by editing the base form properties.
But you want to change the template. That's easy to do as well. Start a new scratch project with one Form and change the properties you want to have customized. Click File + Export Template. Select Item template, Next. Tick the form, Next. Next. Give it a good name and description and click Finish. You can now select that template whenever you create a new form.
Create your own form control that is derived from the base one and has all the properties set just like you want them, then you can use this one all over your project. Also changing something will be very easy since you'll have to do it only in one place.
Is there a way to change the default ajax progressbar that is there in dotnetnukes.
Its not for changing the image but i would like to use an altogether different progressbar. The current one displays the progressbar at the bottom of the section. The requirement to replace it with one covering the entire section or part of it. The section has a search criteria on top and the results below. The progressbar needs to appear above the criteria so that the user will not change it while the search is going on.
That's the animated image you can replace with your own if you have one.
Agree with #DangIT, you can find the gif with name progressbar.gif in images folder in the root of dnn installation. just delete it, and place another image with the same name will do the trick for you
