Hi, from what i know i can use WPF to create browser app using C# code.
My question is , can a WPF application (that is to be viewed from internet browser),be accessed from a central server by many clients over the internet/intranet(intranet is my case),so that users don't need to install the app(except they must have prerequisite .net framework 3/3.5)
I am asking this because i have not learnt ASP.NET yet,so want to see if WPF is better AND future alternative.
-Thanks

Yes - take a look at ClickOnce deployment.

I've been messing around with Silverlight for the last week, trying to get a handle on Prism v2 which was released recently and I had some struggles working with the WCF client proxy generated by Visual Studio. I was trying to use the interface which was generated so I wouldn't have any service dependencies when it was time to write tests. I think the result has been a pretty good implementation, and since I had trouble finding a lot of recommendations on it I wrote a blog post about it. I'd appreciate any feedback as I'm looking to use Silverlight in an upcoming project and I'd like to know if I'm getting things right or if there are some problems I haven't seen yet.
Here's the link to the blog post: http://developmentalmadness.blogspot.com/2009/03/silverlight-and-prism-decoupling-wcf.html[^]

Hello,
I have a problem with my TreeView not showing the vertical scrollbar correctly. I have plain old TreeView without any kind of style, item template or anything. If I add so many items that they start to appear past the TreeView window, I get a vertical scroll bar. This is pretty standard stuff, I know. But the problem is that the scrollbar itself is strange. Both the up/down scroll bar buttons, which are usually located at the top and bottom of the scrollbar, both appear at the top. Plus, there's no scroll bar thumb between them. I don't know why this is happening. In the design window, the scrollbar is normal.
I just find it strange since my tree view is so basic.
Any ideas?
Thanks!

Mine just works noraml. Are you setting any styles ?? might be the reason.

As I mentioned, there are no styles or anything applied to my tree view.
Here's an example as basic as I can make it.
<Window x:Class="TestProject.TestWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window7" Height="119" Width="92"
xmlns:local="clr-namespace:TestProject.Breeze">
<TreeView Name="_treeView1">
<TreeViewItem Header="Employee1 Very Long String">
<TreeViewItem Header="Jesper"/>
<TreeViewItem Header="Aaberg"/>
<TreeViewItem Header="12345"/>
</TreeViewItem>
<TreeViewItem Header="Employee2">
<TreeViewItem Header="Dominik"/>
<TreeViewItem Header="Paiha"/>
<TreeViewItem Header="98765"/>
</TreeViewItem>
</TreeView>
</Window>
I'm absolutely stumped. And it occurs on my collegues' computers as well.

Do you see the horizontal scrollbar? What happens if you stretch the window horizontally, and then expand the treeview? I've just run your sample and it behaves the way I'd expect it to - you see the small vertical scrollbar because there's a horizontal scrollbar taking up space.

I fiddled a bit with my code and found the cause, even though I don't really understand why.
My application uses a directx renderer from a DLL that's written in C++. To init the renderer, I pass it the WPF window's hwnd by using WindowInteropHelper. Now the interesting bit: If I init the renderer before creating and showing my modeless dialogs (the ones with the scrollbar problem), the scrollbars don't appear correctly. But if I init the renderer *after* creating the dialogs, the scrollbars are fine.
If anyone has an idea of why this happens, I'd be happy to hear it!

Hi,
In WPF application I want to fetch collection object and bind that with radio buttons. But I can’t do that directly as there is no property like ItemsSource available for radio button so I researched for it and found one example on below link
http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/5137aabc-bb3a-478a-9438-bc93dd9cc0ac/
Example is working fine. But In my project the method that would be invoked has a collection return type and I don’t know what should be the value for ObjectType instead of enum
<objectdataprovider x:key="WindowStyles" methodname="GetValues" xmlns:x="#unknown">
ObjectType="{x:Type sys:Enum}" >
<objectdataprovider.methodparameters>
<x:type typename="WindowStyle">
What value do I need to set for ObjectType="{x:Type sys:Enum}" > property
Thanks & Regards,
Deepak.

If you want to apply a collection to a radiobutton, then you're better off doing this like this[^] sample.

What do you mean ? What page are you talking about ?
Have you taken a look at the Navigation service feature WPF provides ? See here Link[^]
I have not used it but it seems to be for both standalone and borwser applications.

You could show your login screen as a modal dialog. WPF is perfectly happy with you displaying dialogs.

No it's not. A standard Windows application can show a Dialog. What you could do - and this is a hack, is show the login dialog before you call InitializeComponent(); in the window class. Then, call Application.Shutdown(); if the login fails.

Any idea regarding this.very urgent

I don't use the Infra grid, so I can't help you on this. If you can't figure it out, you should raise this on the Infragistics support forums - they are the best place to figure vendor specific issues out.

Hi All,
I have just started playing with this for the first time. I have set up a Class that inherits from ValidationRule and just popped a Console.WriteLine in there for now ... anyone know why this isn't being invoked?
<ComboBox.ItemsSource>
<MultiBinding Converter="{StaticResource BestGuessFieldLabelDropDownListConverter}"
UpdateSourceTrigger="PropertyChanged" ValidatesOnDataErrors="True">
<MultiBinding.ValidationRules>
<l:MappingValidationRule/>
</MultiBinding.ValidationRules>
<Binding RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type wizard:Wizard}}" Path="DataContext.SelectedDataMapping" />
<Binding RelativeSource="{RelativeSource self}" />
<Binding RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type wizard:Wizard}}" Path="DataContext.AnalyseResults" />
</MultiBinding>
</ComboBox.ItemsSource>
|
|
|
|
|
The Validation fires when the binding to Source is being updated. More clearly stated in MSDN,
"Validation usually occurs when the value of a target is transferred to the binding source property. This occurs on TwoWay and OneWayToSource bindings. To reiterate, what causes a source update depends on the value of the UpdateSourceTrigger property, as described in the What Triggers Source Updates section." Link[^]
You might want to have a look here[^] also.

Indeed. Whilst I was debugging I came to this conclusion! Thanks for the reply.
Seems this is not the droid I was looking for ...

I'm writing a listview:
<StackPanel Margin="8">
<ListView Name="listView" ItemsSource="{Binding}">
<ListView.View>
<GridView>
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}" />
<GridViewColumn Header="Age" DisplayMemberBinding="{Binding Age}" />
<GridViewColumn Header="Grade">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Grade}" Foreground="{Binding GradeColor}"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
</StackPanel>
The foreground color of column 'Grade' is decided by the property GradeColor. It can be Green, Yello and Red.
When I select an item in the listview, the background color of the selected item turned to blue, and the foreground color of the first two column turned to white, but the foreground of the 'Grade' column didn't change to white, which cause the text is unreadable when the item is selected.
Is there any way that I can make the foreground of the 'Grade' column to be white like the other columns when the item is selected? Thx!
