Modal UserControl visibility

Posted By:      Posted Date: October 27, 2010    Points: 0   Category :WPF
In WPF mainwindow I am have usercontrol defined like below,

<local:UserControl1 x:Name="DemoUserControl" HorizontalAlignment="Center" VerticalAlignment="Center" Visibility="Hidden" />

When I want to show the usercontrol in MainWindow's code behind I am flipping the visibility to visible.

Now, I want to know how to make usercontrol as 'modal' after setting visibility to visible.

Any ideas?

Tab container rendered with visibility:hidden - This was reported over three years ago.



Here is (more) code that demonstrates the issue.  If the control in the host page is removed the tab control renders correctly.  Otherwise it is rendered with the visibility attrubute set to hidden as reported in the above link.  Is this broken or am I doing something wrong?

Pass a grid column value to a Modal


Hi, I have a requirement to hide a field called details on a gridview and show it in a jQuery modal dialog when users click on the Customer ID hyperlink. This grid is created programmatically. I will be hiding the details column via the CSS display:none property. Does some one know how can I pass the grid's selected hidden column value to the modal? Here is some of the code I started:

            GridView mygrid = new GridView();
            //.....................................More columns code for the grid

            //Here is where I need to pass the Details column value associated with the customer ID field selected to the Modal and open the Modal dialog.            
            HyperLinkField linkField = new HyperLinkField();
            string[] dataNavigateUrlFields = { "CustomerID" };
            linkField.DataTextField = "CustomerID";

Dynamic Data Entities Modal GridViewPager not showing


I am using the ModalEF template, converted to a web application.

The GridViewPager is not showing up, though everything else works fine (filters, updates, etc).

I have tried several things in the last two weeks, to no avail.

Any assistance would be greatly appreciated.

The GridViewPager.ascx.cs Page_Load fires, but the Page_PreRender does not.

When I click on a link button in gridview, I would like to popup a JQuery modal window and fill the popup(this contains textboxes, then a gridview which contains mapped systems for thet customer, and another gridview which contains list of configured reports for that customer) with the details based on the customer name(link) clicked.

Refreshing a Jquery modal dialog after closing another Jquery modal dialog


I have one aspx page which contains a webpart. The structure of the webpart is:

Webpart(holds one user control say UC1)

      UC1-> contains another user control say (UC2) in a <div>, which I am going to show as a popup on clicking of a link button inside a gridview in UC1.

      UC2-> contain another user control say (UC3) in a <div>, which I am going to show as a popup on clicking of a button inside in UC2.

That means -> UC1(main page) ------->(Onclick) One JQuery popup(UC2)--------------->(OnClick) One Jquery popup(UC3) here UC2 is still remaining in focus and UC3 will be another Jquery popup on UC2.

Now my requirement is when i fill the Jquery popup(UC3) and click on save button in UC3, I would like to close UC3 Jquery popup and refresh the gridview inside UC2 Jquery popup without closing it.

Is this possible?(please explain the logic if found in terms of Jquery, but not in terms of normal popup windows)

UserControl, CustomControl Design Time Support errors IOC, Dependency Injection, MVP

  Hi, is there a way to completely disable design time support for CustomControl, and UserControl ? I have about 30 UserControls and 10 CustomControls in my WinForms app, which contains some Dependency Injections and IOC stuff in constructors and Load handlers. I have lots of large UserControls containing smaller UserControls (CompositeView). All my UI code is pretty dynamic and the only thing i need to do at design time is to drag&drop containers in other containers (UserControls). And now i have a hard time doing this, because i have to wrap all constructors and Load Handlers in CurrentProccess!="devenv"... and when I'm Implementing some new View interface (which consist lots of properties) in UserControl all those properties by default throw NotImplementedException and i don't always need to implement them immediately but still i need to be able to run this code for testing. Besides, then i have to clean up designer generated class because it adds unnecessary null value property initializations, and then it way add some other ____ code, and so on.... Imagine UserControl with 10-15 nested UserControls, and then i try to open it in Form Designer and get ObjectReference NULL exception (for IOC) or some NotSupported NotImplemented exceptions (for properties) without adequate CallStack available! There is a CallStack but there is no trace in it to my Code (
