I am following the 'Stock Trader RI' example by the Prism team,
but it does not address this exactly :
I have a Shell with a Main Region in it.
In this shell I have some filter fields and a grid.
When I press on a button - I would like to load a screen that allows me to change the filters,
and then press 'Save'. This would then call a service to update the fields, and close the pop-up.
Here is an illustration of the 'Shell' before pressing the button (left) and after (right) :
Problems are :
The 'Stock Trader RI' sample app only uses a modaless dialog popup. I need a MODAL pop-up (background will continue to refresh, but user will not have access to it as long as pop-up is active).
Need to have Silverlight-like effect when pop-up shows, meaning - 'Shell' needs to appear 'disabled' (like a gray mask over it).
Pop-up window should have no 'X' button and no 'minimize' or 'maximize' buttons. The pop-up window should be simply a rectangle with curved-corners.
I don't think I can use a 'Notification Window' or a 'Confirmation Window' because I cannot put inside them whatever I want. This is an example with 2 fields, but the pop-up might be much more complex with tabs, and a lot of information shown to the user.
So how do I show a modal pop-up from my "WPF+PRISM" Shell-View-Model once the 'Edit' button is pressed ? (Meaning, once the 'EditCommand' is executed...)
I have found a solution here.
Basically it uses InteractionRequest and it allows me to open a window (that I can style however I want, without the 'Maximize' 'Minimize buttons), and also - I can choose for it to be Modal.
Great thing about this solution is - that I can use custom pop-ups and not only Notification or Confirmation pop-ups.
Also - I can pass information back to the class the invoked the 'InteractionRequest'.
Only thing that it doesn't solve - is that I cannot make the calling view look disabled by adding a gray semi-transparent over it ... haven't figured out yet how to do that...

I've got a WPF form inside a window and a short series of events like this:
1) 1st form has series of selection buttons
2) Clicking a button brings up a progress bar window over the existing window
3) Progress window closes and 1st form switches to a new 2nd form using page navigation
The problem is that the 2nd form (and the entire window) no longer has any focus and what's really killing me is that the window is no longer getting OnKeyDown() calls (it's still the top winow). If I hit the tab key the first menu option is highlighted and the following key stroke will fire a OnKeyDown(). Also, if I alt-tab to another app and then alt-tab back to my window it will begin receiving OnKeyDown() again.
How do I figure out where the focus is after the dialog?
If you are using navigation then the focus will have switched to the Page that you have navigated to, assuming that it is Focusable.
You can check that by setting up a breakpoint in a Focused event handle for the Page.
Alternatively you can use an explicit control.SetFocus() in the page.Navigated handler.
New Thought, Maybe I am looking at this totally incorrectly. So Here is exactly what I am trying to do in case there is another option I am not aware of.
I have a WPF app, the main window shows a smaller dialog window using ShowDialog(), when a user clicks on the parent window that showed the dialog, I need to make the dialog window, flash, shake or blink.
AresAvatar posted a link that looks like it might be able to use, but is there another option I am not aware of?
My original Question.
Mouse click event when Modal window's parent is clicked in WPF app?
I have a wpf app that shows a modal window using ShowDialog().
I would like to fire an event when the user tries to click the parent window that is now disabled.
Is it possible on the parent to receive a click event when it has shown a modal window?
When I attempted this using an interaction trigger, the events never fired on parent window.
Otherwise, what suggestions / options are there.
Thanks
No WPF events are sent under these conditions. The only Windows message I can see that gets sent is WM_WINDOWPOSCHANGING. You could check for that message, and check if the window was disabled when it occurred. Here's a good article on checking WM_WINDOWPOSCHANGING.
Edit: that link seems to be dead. Here's an example on StackOverflow of checking window messages.
I know this is an old question but I'll post my solution in case any one needs it.
Set the dialog.owner prior to calling ShowDialog().
var dialog = new DialogWindow();
dialog.owner = MainWindow;
dialog.ShowDialog();
The result is that clicking on the main window, brings the dialog window to the front and makes the dialog window flash.
I have an application that connects to a server. In the status bar I show the connection status, and on a click I want to open a "menu like" subcontrol over the status showing control where more detailed connection information is shown (like: user name, server name, ping delay, disconnect / reconnect button).
This should basically look like an inverse menu - and when the user clicks outside of that area, the outside click should be suppressed (not triggering anything), but the detail info box should disappear.
I am a little at a loss here - first time I am to do something like that in WPF.
Which control would be advisable as base here? So far I have a custom control for the status bar - but basically it renders as a text box. Note tha the popup is not a menu - it should show a detailed view of the control, so I do not think I can reuse any existing control.
any Hints how to accomplish this?
Thanks in advance.
Two controls to look into:
1. Expander (this could work, but be carefull, it can shift your other controls
2. Button with template. Make a controltemplate for a button that includes a Popup item. This item can then be bound to a set of triggers/events in the button or in the wider form. I hope this helps :)
I'm trying to show a context menu when I left-click a NotifyIcon. Just calling NotifyIcon.ContextMenuStrip.Show() doesn't work very well. A solution has been posted here before that calls a secret method using Reflection:
Dim mi As System.Reflection.MethodInfo = GetType(NotifyIcon).GetMethod("ShowContextMenu", Reflection.BindingFlags.Instance Or Reflection.BindingFlags.NonPublic)
mi.Invoke(Icon, Nothing)
This works great, except that I also need to control where the menu is shown. I want to wait for the SystemInformation.DoubleClickTime to elapse between receiving the NotifyIcon.MouseUp event and displaying the menu, so that I can handle single-clicks and double-clicks separately. But invoking the ShowContextMenu method displays the menu at the current mouse position when ShowContextMenu is called, not when the icon was actually clicked. Which means that if the mouse moved during the DoubleClickTime, the menu will be displayed in a different part of the screen. So if I can control where the menu is shown, I can just save the mouse coordinates when I receive the MouseUp event, and then I can ensure that the menu is displayed near the icon. Is there a way to do this?
Thanks in advance.
Well, I just discovered that there are existing programs that exhibit this same behavior. I just went through all the icons in my system tray and about half of them do it. If you left-click the icon and then move the mouse during the delay before the menu appears, the menu will appear at the last mouse location, wherever that is on the screen. Snagit is one application that does this. Outlook is the only program in my tray that always shows the menu where I clicked the icon. But Snagit looks like it's using a .NET ContextMenuStrip, while Outlook is probably using a native menu.
So either this is standard behavior, or it's a problem that no one else has been able to solve either. And as a user, I've never noticed this behavior until yesterday when I was testing my own application. So I guess it's not that big of a deal and I won't worry about it.
I am looking for a way to once I see a form by Name add a button to that form and when the user clicks the added button, pull information from the form. For example, if I see the for title - "Stack Overflow - Wnidows Internet Explorer" I would add a button "MyButton" on the form, and when that button is clicked, I would "pull" the information from the "search" box. It should work on Web or Win forms.
Any help would be greatly appreicated.
I found my answer
You need to get the window handle to the form in question.
To put the button on another form you need to create the button and set its owner to the other window and set the buttons window position.
You can use the same window handle to enumerate the child windows to get the text if its an edit control.
