Slightly different issue: SetFocus from control to WPF parent window in C#...

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

I've just spent about an hour seaarching for something that should be easy to find with the question: How to set focus on a WPF window.

I have a StatusBar item. When the mouse leaves that item, I need to set the focus back to the StatusBarItem's parent window.

I've tried everything I can think of.  Sorry to be so dense, but I am still a WPF/C# newbie.

Please advise.

Composite Control which contains arbitrary content defined in .aspx of parent and thier ViewState


I want to write own control which can contain other. And I want to define content of the control in the .aspx file where the control is defined. I have written such control. But now I have issue with ViewState of inner controls of my control. The following samle illustrates the issue: I defined two asp:DropDownList ID="ddl1" and ID="ddl2" One of them is inside of my control and other is outside. When posback is occurred asp:DropDownList ID="ddl1 loses state and becomes empty. How to say ASP.net to store state of inner controls defined by this way?

Menu control rendering issue with IE8



Using VS2010, I created an ASP.NET 4.0 web application and simply added a couple of menu items below the "Home" menu item in the master page that's created by the project wizard. I made no other changes - no code, no stylesheet changes.

If I run the app locally then everything is fine. I suspect because the local IIS is responsive enough for the problem not to occur.

If I deploy the app to a web host (discountasp.net) then I see the menu render vertically for less than a second before it renders correctly. If I refresh the page a few times then usually I can see the menu vertical flash but sometimes I can't, so there's some sort of timing consideration.

I'm using IE8. The problem doesn't seem to occur with either Firefox 3 or Chrome.

Have others seen this problem?

Any suggestions for a fix?

I can supply the zipped up project if anyone wants it.

Issue with Remember Me on User Login control


Hi everyone,

     I hope you can help me, I tried Google, but none of the solutions worked. Using VB.net and Membership, I have a login control in my master page with a remember me check box. When I check this box and login, some pages indicate that I am not logged in. If I go to another page, it will then indicate that I am still logged in. I have isolated one page that always indicates I am not logged in the first time I visit it, but if log in a second time and then go to it, it will finally recognize me as a user that is properly logged in. 

Some pages that this occurs on is in the top level, some pages are in a sub folder.

My MasterPage has the following Form Code:

<body bgcolor="#E0ECF9" topmargin="0" leftmargin="0">

    <form id="form1" runat="server">

My Aspx file has a troubleshooting label, several Gridviews and several DetailViews:

    <asp:Label ID="lblErRep" runat="server" Text=""></asp:Label>

My aspx.vb file has 1 line of code (Protec

Binding an event method from a control in a seperate window

How would you bind a event method from a control back to a seperate window?  I have a ActiveX control hosted in a WindowsFormsIntegration wrapper.  That is operating in its own window along with all its events.  The properties of the control are handled by a class that defines the dependency objects (thanks Bob) to provide a view model between it and a window with controls for setting/getting those properties.  Since events constrained to Window 2, is it possible to bind the events back to Window 1?

Issue with Repeater control.

Hello. I have a Repeater control which contains asp:Button control in ItemTemplate. I want to handle Button's Click event, but when I'm clicking that Button the error is thrown: Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.But on other computer that piece of code is working.I set EnableEventValidation to false, but it's still not working. Please help me out. 

Parent window does not get reloaded - Permission denied error

Hi, When a button from a web form (say parent) is clicked I am opening another form(say child). And once the child completes its processing, it has to reload the parent form and close itself. For this I am calling the below javascript in the child form: function CloseMe() {     window.opener.location.reload(true);    self.close();    } But when the browser tries to execute this javascript code, it fails and throws Permission denied error. Here, the parent and child forms are from different domains. Please throw somelight on this. Thanks!  

The OTHER Menu control issue...

Ok, everyone knows that the z-index is messed up in IE8 and that requires patches or workarounds...What I can't seem to find a solution to is the white background on the DynamicMenu parts of a Menu control.  Setting the background color to transparent or not setting it all doesn't seem to have any effect.  This is only a problem in IE8, Firefox 3.6.8 renders the dynamic menus without the white background.

How to Access Parent Page (.aspx) control (IDs) from its child User Control (.ascx)

I have a parent .aspx page that has a asp:panel control in it, and this parent .aspx is also referencing a user control that I registered in that .aspx. Lets just call it usercontrolA.ascx for this post.The user control has a radiobuttonlist itself.Based on a selection from the radiotbuttonlist in the user control, I want to be able to hide the asp:panel in my .aspx (parent) but unfortunately I cant' get it to work:parentPanel.visible = true;  <<< I trried this in usercontrolA.ascx.csBut the user control doesn't know about the panel in the parent .aspxSo do I need to expose that somehow from the parent so that I can access it from the code behind of the child .ascx?  How?

LoginView Control Issue

I'm using VWD 2010 Express, and I'm working on a school lesson that I actually did approximately 2 years ago In VWD 2005 with no problems.  I am just learning to program, so my knowledge is very limited.The lesson walks me through creating a master page and then I created a page called "Login.aspx".  On the login page, I am dropping a LoginView control into the ContentPlaceHolder section, and then I'm supposed to type "Welcome !" into the LoginView box for the LoggedIn template, but the LoginView box is very small and when I start typing, the first couple of letters go into the LoginView box, and then they start showing up on the far left outside of the LoginView control.  When I try to click back in the LoginView window, it will only select the entire control, and I can no longer modify what's in the box (unless I go to Source view).  I can't even begin to explain how frustrating this is!!!  It's tough enough trying to learn this stuff and now my development tool is giving me grief!  I don't understand why it worked fine in VWD 2005, but not now (and I'm using the same exact lesson material).
