I want to create an application and chatting is involved. I am currently struggling to format existing controls or to create a control with the following conditions:
a container is docked to the main form's bottom
inside of that container, a button can be used to toggle a chat
component (e.g. text edit) to become either visible or invisible
if visible, the chat component is aligned with the button that was
pressed but does not force a resize on the container of the button
So basically I want to achieve a facebook or google hangouts like chat layout in vb.net that can also scale dynamically according to the current window size. Nevertheless it should always stick to the bottom.
Please keep in mind that this question is not about making the chat work but only the layout/design problem I am facing.
My current approach is the following:
FlowLayoutPanel docked to bottom with buttons
RichEdit as placeholders to simulate the chat component
My current layout
Is there an easier way to do what I want to do?
Set the anchors to the bottom of the page/panel.
On the designer, click the control you want to edit, find the Anchor property and change it to bottom (and left/right/top, whatever you'd like).

I have a user control with a bunch of buttons behind a scroll viewer that has a grid with a bunch of rows in it. The first row is empty. The buttons in user control need to respond to tap/click when not obscured by scroll viewer's content. My problem is that the scroll viewer caches the tap event and it is not passed to the user control because it is a sibling to the scroll viewer. I would like to somehow pass/propagate the tap event to the user control to get the buttons working. I can't find a good solution to this issue because there seems to be no RaiseEvent(e) method on UI elements in uwp. Due to specific requirements, the whole page needs to react to scroll and the buttons are required to be behind the scroll viewer content. Does anyone know if it is possible to pass the whole event to another element or somehow allow for both controls to handle it? Thanks in advance.
Is it possible to implement mouse click and drag selection box in GridView UWP Windows 10. Should it be done through simply drawing a rectangle, calculating coordinates of its points and evaluating position of other objects inside this box? Or are there some other ways?
Could you give a bit of sample code or a link?
The Universal Windows Platform does allow for Drag-And-Drop behavior. This includes drag from app and drop outside of app, drag and drop inside the app, and drag from outside the app and drop in the app.
The way to do this very simple (with room for heavy customization if you feel like it is needed): UWP XAML controls have a CanDrag and AllowDrop properties. The former is just a property of whichever control you're dealing with, the latter is an event that needs to be handled properly via code. If you want to further customize your app you can also handle the DragOver, which handles behavior when a dragged item is over a drop area but has not been "released" yet.
For further details and a bit example code please read Microsoft's own documentation for Drag-And-Drop. For a more built up example, you can check out the following Github repo.
I'm writing a codenameone application where I want to have an image displayed across the top of the screen as a header. I do not want to include this image in every form/container that I create so therefore I came up with the following solution:
I have a Main form which contains the image (North) and a container (Center) which will then hold all the components of the specific screen that I want to show.
I will then create containers that represent each individual screen. My idea was to add these containers to the container of the main form, one by one and that navigation between them would be handled by changing the contents of that main screen container.
But I cannot find out how to make this work. As long as I have one single screen to show it is easy... The main form container can be an embedded container that is set to show the container for the single screen. But when I try to navigate to another I cannot make it work.
So, is there another approach I should use?
If not, how should I handle navigation between screens?
Is this with a GUI builder app or with a handcoded app?
Either way a simple way of customizing this if your app has a side menu or Toolbar would be to customize the TitleArea UIID to include your background image. E.g. start with a modern theme like the Business Theme and in the designer theme change the title area border property to be "Empty".
Then define the background image to be the image you want with "scaled to fit" or "aligned bottom" depending on what you want. Make sure to include enough space in the image for the title are and use a multi image so it will adapt for other OS's.
Is there any property of pop up , wherein we can dim the window app.
As in metro app there is no Child Window control available , so using
popup in place of it but the problem in popup is when it is open the
user can still interact with other control on window app.
So is there an workaround to make the window app dim when pop is open.
I'm not sure to understand what your trying to do. You can put a Border as first child of the popup which exposes the Background property. So if you specify a not null Background (Transparent for instance) the popup will catch every interactions.
It sounds like you want the MessageDialog class. The popup is meant to be non-modal, letting the user close it by just clicking away from it. The MessageDialog is a regular modal popup that does not let the user interact with the rest of the app when it is displayed.
If you really insist on using the popup control, here is a simple workaround:
Make the popup use all the screen (using a grid or border), then set that background to Black with opacity 0.1 (or any other color you see fit, this is to give a "dim" effect), then inside this popup, place another container with the size and margins that you want to act as your "real" popup.
Because the popup takes the whole screen it will prevent the user from clicking anywhere in the screen.
I'm working on a iPhone app which shows an mobile webform in a UIWebView. I'm using a default iOS layout with a navigation and tab bar.
The mobile webform is displayed in a UIWebView in the white area. Since the webform has a lot of input fields, we really need as must space for it as possible. Because of this, we are planing to remove the tabs in the bottom. Over time, there will be more tabs/sections, so it is not a solution to just add a button for each section in the left side of the navigation bar. On a iPad a popover could easily be used to handle this.
Is there a standard iOS layout mechanism to handle this change of sections/views without using tabs?
You could do something long the lines of Path or the new Facebook app and have the "table of contents" behind the Navbar and the navbar slides away (along with the child view) to reveal it. When done right (ie smoothly) I think the effect is really cool.
This would also work great as you add more and more options, since the table could just scroll.
Here is a framework that might be you started: http://www.cocoacontrols.com/platforms/ios/controls/iiviewdeckcontroller
I would consider replacing the navigation bar's title with a control that lets you switch between tabs. You can assign the bar's titleView property to a control or a button and it will generally do the right thing.
If you're limited to 2-3 tabs, you could simply use a UISegmentedControl.
If you want more, you could use a button which, when tapped, pops up a view that allows you to select the view you want. This could be a modal table view, or you could slide up a UIPickerView from the bottom of the screen, similar to the keyboard.
I use this technique in an app of my own, screenshots here. Tapping the button cycles between views (in this case, I'm changing the contents of the table cells); tap-and-hold slides up a picker.
Another possibility would be to arrange your different forms on pages in a scroll view with a page control at the bottom, à la Weather. The best option, though, if you’re going to have a particularly long list and want to keep your screen real estate, is probably the FB/Path-style sidebar table.
I ended up using a UIActionSheet but I think it in other situations would be more stylish to use a controller like the IIViewDeckController.
