I want to preface this by saying I'm a noob with WPF/.net programming.
Here is my question that requires a bit of guidance. I have a window and I load pages in and out as my navigation. On one particular page, when the user clicks on one of the items (button for example), I need to display a small form to gather more information. I'm not sure what the best approach is... what I would love (but do not know where to begin even searching for this solution) would be to open a popup balloon style window with a few textboxes and a submit button.
Other options I've explored would be to use a separate page. Save off the current page and load a new page with these textboxes and a submit button. Or to use a custom messagebox instead (least favorite option).
I would like this new extra info page to blend in with rest of the app so that the main page is still visible in the background. Any suggestions??
You can use WPF's Popup control
<Popup>
<!-- Your Content Here -->
</Popup>
Personally I have issues with WPF's Popup, so have my own custom UserControl that works like a Popup.
I ended up using modal window (ShowDialog) method for this.

I will try my best to express what I do not understand about WebForms. Maybe somone can explain it to me....
I work in 'quite big' WebForms (website) Application.
Application already has a PopUp (which I HAVE TO USE, because I dont have time to make a new one) like MessageBox in Winforms, but:
it's place is in MasterPage.master (I use it like ((MasterPage)Poup.Show("blablabla", yes_no));
I can add buttons to it and change style etc.
it doenst stop application (like .ShowDialog() in WinForms), so I have to assign onClick events dynamicly and assign/catch them on Page_Load to go to the wanted method depending on users input on form. At the moment i can't to anything about it.
And here is the problem:
Depending on form validation, if users press a button (on a form) - then form realods it's TextBox.Text's values and changes DropDownLists's SelectedIndexes and SelectedValues.
BUT IF YOU GO TO THE SAME METHOD WITH MY POPUP WINDOW:
ex: Do you confirm? YES/NO
If you press You press ANY button, then: CHANGES ARE VISIBLE BY CODEBEHIND BUT TEXTBOXES ARE STILL VISIBLE WITH PREVIOUS DATA ON THE SCREEN, ALSO DROPDOWNLISTS HAVE OLD VALUES SELECTED
BUT IF YOU PRESS A FORM BUTTON (WHATEVER WHICH), EVEN IF IT'S METHOD DOES NOTHING - ALL FORM WILL "RELOAD" AND HAVE PROPER DATA ON THE SCREEN.
(it's not about Runat="server" or AutoPostBack, I checked it)
I dont event know what to do about it :(
Update panels are used to partial refresh of some fields inside him, caused by certain triggers, like buttons, textchanged, etc.

(Haven't worked with web forms events in a while, just answering in case nobody else does.)
Out of curiosity, what happens if, in your javascript handler for your popop button, you getElementById one of the form buttons on the main page and call ".click()" on it?
The basic problem sounds like there's a runat/server form on the main page, with certain behaviors associated with it, which is submitted by the main page runat server buttons but not by your popup JS.
Easy enough to test with the above approach. If that works, take a step further and try to figure out why it worked, based on what those buttons are doing.
(If you're not using JS at all for the popup, then View Source the output HTML, because I'm sure it is. Backtracking those calls should help you understand the trace from popup button press to form submission.)
I probably mislead you by "OnClick", it's NOT javascript OnClick="method()" issue.
I mean ClickEvent on a button (in codebehind). For Ex. If form is validated I have to do:
ViewState["PopUpSelection"] = "yes_no";
(MasterPage)PopUp.Show("blabla",yes_no) //loads popup from MasterPage;
return;
then on Page_Load I have:
**if (string)ViewState["PopUpSelection"] == "yes_no"
{
ButtonConfirmYes.Click += new EventHandler(MyMethod);
}**
And if method "MyMethod" is called from a FORM button, everything "will go ok".
If you call the same method from PopUp button: changes are visible by codebehind, but on the screen nothing happens, unless i press ANY FORM BUTTON, whatever it does
Pre-warning, I'm new to C# and XAML, but I'm really enjoying Windows 10 UWP apps. I've got a question on how to appropriately handle a SplitView.
I've got a Main Page, in which I have a SplitView control. In the SplitView Content, I've added a Frame for navigation to other pages. I want to add the Hamburger button on the child page to open the SplitView on the Main Page, but I can't access the SplitView control from the child page. How can I make the SplitView control accessible so that the hamburger button within the sub-page can open the SplitView pane?
The alternative is to add a header in the Main Page and have a static hamburger button there, but I don't like this option as it makes handling the text header content more difficult. Another is to copy the SplitView to each page. I don't want to do this either.
Any advice would be fantastic! Thank you.
I would highly recommend you take your alternative option of including the hamburger button in the main page. Users always expect it to be in the same location every time and changing this approach will probably result in a bad user experience.
You also don't want to be repeating code and thus you don't want to recreate the button on every page as well as any additional functionality like the open/close commands.
Rather than referencing elements from one page to another, a better practice is to keep things loosely coupled. This can be done with a messenger plugin which sends an event from one page to the other which can give it instructions on what you want to do. That way the other page only has to listen for the event instead of holding strong references. To streamline some of this process you could inherit from a base class which implements the messenger functionality.
That would provide a solution to your button and your header text situations but setting them up is out of the scope of this question. Depending on the size of you app and your goals, you might like to look into existing frameworks which helps in designing maintainable apps. A good Mvvm framework I would recommend checking out is MvvmCross which also cross platform and contains a messenger plugin.
Good luck with your app.
I found that solution :
In the MainPage, in your SplitView pane button method, add a SplitView reference as parameter in Navigate() :
private void SlitViewPaneButton_Tapped(object sender, TappedRoutedEventArgs e)
{
var frame = contentFrame;
Page page = frame?.Content as Page;
if (page?.GetType() != typeof(ChildPage))
{
frame.Navigate(typeof(ChildPage), SplitViewName);
}
}
In your ChildPage.xaml.cs :
protected override void OnNavigatedTo(NavigationEventArgs e)
{
SplitView sv = new SplitView();
sv = e.Parameter as NavigateControls;
}
You can now do sv.IsPaneOpen = false, in your ChildFrame code.
Note : if you want to pass several Controls, create a Class with these Controls as variables, and use an instance as parameter.
As stated above, it is better to keep your hamburger button in your main page for a couple of reasons. One is the consistency mentioned above. Second, you would have to recreate the hamburger button in each of your content pages instead of just once in the MainPage.xaml. Additionally, keep in mind, there are different kinds of interactions with the SplitView menu in terms of how it pops in and out and how it is displayed, all listed below.
Inline – When the menu pane is opened, it pushes the content over. When it’s closed, the content goes back to its original location
Overlay – When the menu pane is opened, it lays on top of the content. When it’s closed, it is invisible.
Compact Overlay – When the menu pane is opened, it lays on top of the content. When it’s closed, the pane is still visible in Compact Mode.
Compact Inline – When the menu pane is opened, it pushes the content over. When it’s closed, the content goes back to its original position but the pane is still visible in Compact Mode.

I have a GMap.NET control on my main form, and then I have a second form that will show when the user clicks on a button. The problem is, that when the user leaves the second window and hovers over the GMap control from the main form, the main form comes to the front. This does not happen when i hover over the rest of the main window with the second window on the front. Also I have another form that will show while the program searches for some data, and this one will also disappear when the user hovers over the map.
I hope I explained it well enough, basically when I hover over the map the main window comes to the front. And it does only happen when there is another form of my project in front of it, not when there is any other window like firefox or something in the front.
So my question is: why does this happen and can I change this behavior? Is it a standard of the GMap.NET control? I am using the Version 1.7.0.0 control btw.
you must use
GMap1.DisableFocusOnMouseEnter = true;
i added this code to my program and problem solved.
It would help to see some code as to how you are showing the forms, but it sounds like you are doing something like secondwindow.Show() instead of secondwindow.ShowDialog(), and then an event from GMap for OnEnter is doing a Focus().
Then, when you have the "other form" in front of it, it's opened in a way that will restrict access to the parent form (ShowDialog(), etc).
I need to show and hide various buttons that are all on the ribbonbar in designer.
Depending on what the user has selected on the form at the time depends on what i want to show/hide.
I cannot figure out how to get the ribbon to refresh properly, showing both the new button (without scrolling mouse over the new button) and resizing (width ways) to allow the new button to fit properly.
i have looked all over the web for other questions that answer this, and asked devcomponents forums, (still waiting on response from that)
I have figured out what works for this.
ribbon.Refresh()
'refresh size of ribbonPanel1, barlayout for the show/hide of miRoom
RibbonPanel1.PerformLayout()
ribbon.PerformLayout()
my button was within RibbonPanel1, and this was shown by a tabItem on the ribbon, the RibbonPanel1 was also on the ribbon (as otherwise it wont show)
Here is the KB article which covers working from code and other details: http://www.devcomponents.com/kb2/?p=472
I have a bunch of Custom Control Forms (i.e. login page, home page, etc.) that I want to be embedded within a "main form". Every time the user navigates to another page, only the content of the "main form" gets changed.
But the only way I can do this is to copy the contents of the Custom Controls and paste them into the "main form" - which is messy. Is there a standard way of doing this type of thing?
Update:
Ok it sounds like possibly you want to use an MDI form or maybe to use user controls (switching out controls for the new pages and such).
Old:
Is it possible you are talking about ASP.net pages and wanting to use master pages?
You might want to use a Panel. Put all the controls for each “embedded form” in a panel of its own. Then you can just show and hide the right panel to make controls appear and disappear.
Alternatively, if you want the user to be able to manually switch between the “pages”, you could consider using a TabControl.
