Part of Window content not minimizing with rest of Main Window.

Posted By:      Posted Date: September 24, 2010    Points: 0   Category :WPF

I am developing an IDE-like WPF application.  The application's main window from the Microsoft  has a number of child tool windows and tabbed document windows. 

The layout system for the main window's child controls has been implemented using the Composite Application Library.

Recently, a problem arose in which two particular elements of the main application window did not minimize with the rest of the window.  Instead, these two child elements stay up on the screen.  However, I cannot actually click on the unminimized region.  In fact, I can drag items from desktop through the unminimized regions.  The only thing that I can think of that may be causing this is that the content that doesn't minimize is executing within a separate AppDomain.  The two UIElements from the different AppDomain are remoted from an Add-In (System.AddIn).

Has anyone else experienced a similar windowing problem?

Dynamic Content In A ModalPopupExtender & Open A New Browser Window

Ok, after searching on how to do this and trying many different ways and failing, I finally got something working.  So, I decided to post it here to help anyone else that might be trying to do the same thing.  If anyone sees a better way to do this then please let me know. I want to populate an update panel with addresses so I use a repeater.  I want the user to click a link and that causes a modal popup to appear for the user to enter thier address so that they can get driving directions to the address listed in the Repeater.  I needed a way to get the address the user was driving to, to also be inside the modal popup because I need to pass it along later.  The reason the list of addresses are in an updatepanel are for paging purposes.  I've used a simple version of the repeater in this example though.<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <HTML> <body> <form id="Form1" method="post" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> <asp:UpdatePanel ID="myMainPanel" runat="server" EnableViewState=false> <ContentTemplate> <asp:Repeater ID="rptItems" runat="server" EnableViewState=false> <ItemTemplate>

How to sync main thread and new opened window

Hi all, I need to halt the main thread until some workflow is completed on the opened Window, the opened window has a user control content in which the user enter some data and click the button "next" . how can i halt the main thread and signal it to continue after the next button has been clicked?

Problems with Master Page and content window

I have a master page whose primary function is to allow a user to search for a Credit Union.  They can either search by ID # or search by name.  With processing this page it will set session variables which in turn I would hope would be passed along to the content window. Within the content window I am displaying the information that will be needed on that particutlar page, if no record is found then it will allow them to add.  I also need it to clear the fields in the content window if they go from one record with data to one without.  Now if a user types in the ID#, then it doesn't seem to have any problems populating the content window.  The problem comes when they try and search by name.  If more then one record is returned then it will populate a listbox.  Which then I would like a user to select the name they are searching for and then populate the search boxes as well as process the content window. The problem I seem to be facing is the Page Load on the content window.  Session variables don't seem to be set in time for the content window to have the variable available to it. Hopefully you can help me out.Masterpage.master.vb Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'ResetValues() Me._txtCUName.Attributes.Add("onchange", "if(document

How do you change the color of the main frame on a Window in WPF?


I have an application where all windows have a very custom look/feel.  When the user has their theme set to Classic, or even set to certain default themes, the colors clash with my main app colors.

Seems like it should be easy to set a brush on the Frame portion of a Window in WPF but this appears to be missing from WPF.

I have searched around, but the only solutions have found involve making the main window transparent and manually creating the border and drawing the frame yourself and handling all the sizing/move options yourself.  I got this to work just fine, however I have a window on which I need to use INTEROP to show an HwndHost on a canvas.

HwndHost doesn't appear when being used on a Transparent window, so I simply cannot make the window Transparent without making my app useless.

I have tried setting the WindowStyle="None" and that gets me close, but shows an ugly thin frame around whatever I put on the window.  I wish "None" really meant none..  Unfortunately, it doesn't.

Does anybody have any way to override the color of the main window frame without making it Transparent or setting the WindowStyle="None" ?

Please help me out with a code sample if you have a good solution for this?

Thanks a bunch,

Problem with a Javascript Popup Window Minimizing itself


I am new to Javascript.  I have seen other posts about this, but I have not been able to resolve my problem. I have a WebPage that allows a user to click a LinkButton. When the LinkButton is clicked. I execute the following Javascript code after registering the ClientScriptBlock:

<script language='Javascript'>
PopupWindow = window.open('StandardImageLookupPage.aspx','PopupWindow');
PopupWindow.resizeTo(screen.width, screen.height);

No matter what I do the popup window comes up for a brief second and then minimizes itself. I prefer that the window stays maximized.

I am stumped. Any help would be much appreciated.

ps. I am not sure if this makes a difference, but the WebForm that calls this javascript is a user control.

Web Part Properties - Need InputFormTextBox to open in a new window.
