WPF Binding Not Showing in Visual Designer

Posted By:      Posted Date: August 27, 2010    Points: 0   Category :WPF
 
I wrote a demo app (download src here) that doesn't properly display sample data in the Visual Studio Designer and I need help. After 6+ years developing in C# and WinForms, I've decided to use WPF in my current project. I've written a small demo application to teach myself and experiment with WPF. The app simply downloads and displays recent news stories from the Google News RSS feed (see Figure below):   My first attempt at this resulted in the class called "GoogleNewsWidget." After reading about the MVVM model, however, I tried again and built "GoogleNewsWidget2" that attempts to utilize a more MVVM-oriented architecture. I'm not sure which implementation is best as they both seem to be working fine on the whole (and though I'd appreciate comments on which implementation is better, this is not my primary question). My main problem is that neither GoogleNewsWidget or GoogleNewsWidget2 play very well with the Visual Studio Designer. The GoogleNewsWidget2 loads and displays data fine when its xaml is opened directly but does not display correctly when embedded into another xaml file. The GoogleNewsWidget does not display data in the Designer in either case (see Visual Designer screenshots here). What's worse, I can't figure out a way to debug stuff in Visual Designer--are there tools for this? Any help would be appreciated

Is it a bug in Visual Studio 2008 in WPF Designer when binding to enum defined inside of class?

  

Hello,

 

I have following problem:

when defining an enumeration inside of class (either static class or not) I can bind to this enum, however the WPF Designer inside Visual Studio does not display designed GUI anymore and show an error Type "MyClass+MyEnum" was not found.

However I can compile and execute the code and in the combobox all enum- values are listed.

 

Code behind:

    public class MyClass
    {
        public enum MyEnum { enumValue01, enumValue02, enumValue03, enumValue04, enumValue05 }
    }

 

My xaml-code:

<Window x:Class="SampleBindingOfNestedEnumToComboBox.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:sys="clr-namespace:System;assembly=mscorlib"          
    xmlns:local="clr-namespace:SampleBindingOfNestedEnumToComboBox"
    Title="Window1" Height="300" Width="300">

Visual Studio closes itself by opening aspx-Page designer after Windows Update

  

Hey Guys,

I've a problem with my Visual Studio.

On the 13th of August 2010 i installed a Windows update on my vista sp2 pc. For this date my Visual Studio 2008 sp 1 always has closed itself by opening an aspx-page in designer view. There is no error message just closing the window. I restored a backup of my windows from the time before updating it and it helped, i could open aspx pages in the design view till the update has been installed again automatically after rebooting the pc. I can't disable windows updates, cause it's my pc at work and safety is very important. I hope you could help me out of this disaster.


Thanks

Visual Studio designer event problem

  

Hi there

I have a small issue that I'm sure others have experienced - but haven't yet found a solution / workaround for this.

When adding controls to Visual Studio in designer you normally get a event button (the yellow flash light) in the properties window.

But when you nest a button inside a placeholder (for example) you cannot mark the button from the designer - only the placeholder! When trying to go into "split-view" on the designer you'll be able to mark the button in the bottom of the designer - but only properties and not the event button appers in the properties window!

I know that you can go into codebehind and manually add the event but I thiink it is really tiresome to do so if I don't have to...

I had a small hope that VS2010 the issue would be gone but sadly it isn't...

Anyone ever found a solution for this one?

Kind regards Thomas


WPF Designer (in VS 2008 and VS 2010) crashes with Visual Studio

  
Good day all. I have the following question: WPF designer in both VS 2008 and VS 2010 crashes with Visual Studio when I try to edit UI form. Moreover, it crashes even when I try to save .xaml.cs file. Meanwhile, Winforms and Dataset UI editors work as usual. Are there other people met this issue? And how could I fix up this problem? Deleting the .suo file, uninstalling silverlight, repairing visual studio, and further googling did not help me. Thanks in advance.

Showing Designer error for Silverlight App when trying to access resource which contains code e.Resu

  
Environment is: Silverlight 4, VS Studio 2010. Designer is showing error in a Silverlight App when trying to access a resource as below. And there are no build or runtime errors. Extensive research found that, in the "InvestorsProvider" class I am using wcf services, which has a callback method. In the call back method I am using this statement "this.MyProperty = e.Result" where e.Result is ObservableCollection. If I remove the e.Result it is not showing any designer problem. <UserControl.Resources> <local:InvestorsProvider x:Name="investorsProvider"></local:InvestorsProvider> </UserControl.Resources> Here is the error System.Reflection.TargetInvocationException [Async_ExceptionOccurred]Arguments: Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=4.0.50401.0&File=System.dll&Key=Async_ExceptionOccurred at System.ComponentModel.AsyncCompletedEventArgs.RaiseExceptionIfNecessary() at SilverlightApplication9.ServiceReference1.GetInvestorsCompletedEventArgs.get_Result() in C:\Documents and Settings\mennis\my documents\visual studio 2010\Projects\SilverlightApplication9\SilverlightApplication9\Service References\ServiceReference1\Reference.cs:line 115 at SilverlightApplication9.Inves

How to display breakpoint and debug visual cues with custom activity designer based on WorkflowViewE

  
Hi,   I am developing custom activity designers based on "WorkflowViewElement" instead of "ActivityDesigner" in my xaml. It allows me to have greater control of the look and feel of the designer. However I noticed that with this approach, the breakpoint visual cue (Dark red solid circle that appears on the left side of the designer when you set breakpoint on the designer) is not visible. It works fine when you write your designed based on "ActivityDesigner". The same behavior happens to the debug visual cue when you debugging the WF. It appears as bright yellow rectangle surrounding the activity designer if you are based on "ActivityDesigner", but it is not available when your designer is based on"WorkflowViewElement". Any help is highly appreciated. Li

Visual Studio 2008 Failing to Add New Controls into *.designer.cs

  
I've encountered a situation with my current project where, when I add a new control, VS2008 is not adding it into the associated Designer file.  This is occurring with both a Web Page (ASPX) and a User Control (ASCX).At first I thought it was because I was going into the layout page and manually adding a control that way.  But then when I went back to dragging the controls right from the ToolBox the problem persisted.Why is this happening and how can I fix it?Robert

Color list view showing in Designer but not in IE or FF

  
I've created some color-coded List views in Designer using a calculated column that renders an HTML tag. I then edited the tag with the "disable-output escaping" set to "yes". The color shows fine in Designer but never on the browser page. I've tried viewing this in IE and FF. Anyone know what the problem could be? Thanks.

Visual Studio 2010 designer UnresolvedAssemblyException

  
I'm having a problem with Visual Studio 2010 that is proving to be extremely difficult to find a solution for. Any help is appreciated. I have a custom library that handles regular expression validation for me. This library sits plainly on our server for everyone to access. In my most recent WPF application I've been learning about ValidationRules. I created my own custom rule that would simply test the input against a supplied regex pattern. Here's an example of the XAML. <TextBox Grid.Column="2" VerticalAlignment="Center" Style="{StaticResource sTextBox}" Validation.ErrorTemplate="{StaticResource TextBox}" SourceUpdated="ProductQuantity_TargetUpdated"> <TextBox.Text> <Binding Path="Quantity" Mode="TwoWay" NotifyOnValidationError="True" NotifyOnSourceUpdated="True" NotifyOnTargetUpdated="True" ValidatesOnDataErrors="True" UpdateSourceTrigger="PropertyChanged" ValidatesOnExceptions="True"> <Binding.ValidationRules> <vr:RequiredField Label="Quantity" /> <vr:RegularExpression Label="Quantity" ValidationPattern="NumberAbsoluteNoDecimals" /> </Binding.ValidationRules> </Binding> </TextBox.Text> </

How to implement Design-Time drag & drop from Custom Visual Studio Tool Window to WPF Designer

  
Hi, Could someone tell me if it is possible to intercept a design time drop event coming from a custom Visual Studio tool window onto the cider design surface? I am hoping to use the same API's as those used by the Visual Studio 2010 'Data Sources' tool window, which provides drag & drop data-binding between classes and WPF/Silverlight controls. My requirement is to pass a DataObject (used with the WPF DragDrop API) from my custom Visual Studio WPF tool window treeview to my custom WPF control at design time, read the data and do some binding/XAML manipulation of my own. The drag aspect is simple enough but I can't work out how to accept a drop event from anything other than the toolbox. At the moment, when I drag my treenode over the design surface it shows the 'cannot drop here' cursor. If someone could give me some insight into how the 'Data Sources' tool window allows dragging of treenodes to controls I would really appreciate it. It is obviously possible but which API's are used and are they public? Thanks in advance, Paul
