Hi,
can u help me know how to proceed with maintaining session state in wpf browser application.
|
|
|
|
|
Hi Puneet,
XBAP is a client side technology, and it cannot use session directly. XBAP is similar to WPF Windows application the main difference is that XBAP application runs on the browser. As you cannot use session in a standalone Windows application similarly session cannot be used in a XBAP application. However, if your web site is developed by ASP.NET, you can disable session cookies. Instead, the session id will be passed by a request parameter in the URL. Now you can use this parameter in your XBAP.
Hope this information will be helpful .

Hi...i'm new to wpf.
I have a problem and i dont find a solution on web.
I have an usercontrol (name PresenterControl.xaml) used as a container for other usercontrols (WindowContainerControl.xaml in this case). From code i think you'll understand what i;m trying to do.
The content of PresenterControl it;s a label. this content will be forwarded inside PresenterContent to WindowContainerControl. WindowContainerControl will put it inside a grid.
i;m getting this error and i have no solution in mind.
Key cannot be null.
Parameter name: key
at System.Collections.Specialized.ListDictionary.get_Item(Object key)
at System.Collections.Specialized.HybridDictionary.get_Item(Object key)
at System.Windows.StyleHelper.QueryChildIndexFromChildName(String childName, HybridDictionary childIndexFromChildName)
please help me if this issue can be solved and if i;m not asking too much please modify my example if you find a solution. thanks a lot.

I wouldn't expect any of that to work!! Don't do things like:
<usercontrol x:class="WpfApplication3.WindowContainerControl" xmlns:x="#unknown">
Your cutting off the other xmlns statements that follow by using a > character at the end of that line for starters. I have no idea what your trying to do with:
xmlns:x="#unknown"
Are you making this XAML by hand in VS? I suggest you go and grab a trial version of Expression Blend and have a play around with that first.

All you have done is define DataTemplates and ContentPresenters incorrectly.
You can almost think of statements like
<myC:WindowContainerControl>
As HTML #include statements. So trying to do things like:
<myC:WindowContainerControl>
<Grid>
<ContentPresenter Margin="3" Content="{TemplateBinding Property=Content}"/>
</Grid>
</myC:WindowContainerControl>
Is a bit weird really. If you want to do that you would have the control presenter *inside* the WindowContainerControl.
Take a step back and have a play with WPF in Blend before moving onto stuff like this, just a couple of days to get your head into the way it works the binding is really complex and not hugely intuitive to start with.

It's good i know that i didn't understand well the mechanism of template-ing and it;s not some bug or something like that. i will study deeper the subject. finally i solved my problem in a different approach.
Once again thanks for your help..as for me i'll do some blending  )

Hi Everybody!
WPF is a great Framework. I love it!
My problem:
I created some polyline objects with Blend, exported and placed them into my window with a grid.
Now I resized my window and my objects resized too, but not as I would like it.
The objects moved in all directions. It looks ugly...
I want to achive a resizing method like stretching an image. Several parts should by resized or stretched as a whole. Maybe resizing the buffer where the objects are rendered?
Do you have a solution or idea?
Thank you!

Thank you! I tried it.
But how to put multiple objects (Images, polylines etc.) into one ViewBox?
|
|
|
|
|
Viewbox can only have one child so use something like a Canvass.
I was just having a play around in Blend to knock up a demo for you but I'm seeing some REALLY odd behaviour with a Viewbox here so it may have to wait a while until I can figure out what is going on here.
I've used Viewbox's with complex/multiple path objects before with no problems.

Thanks Pete!
I've looked through the "WPF Unleashed" book by Adam Nathan and it doesn't mention this at all, it's too cool a technique to not share it!
I think the best thing about it is that it provides an even nicer way to *really* get into the design side of complex DataTemplates through the use of Expression Blend. Using the 'inline' method your still left in the dark in terms of how your DataTemplate is *actually* going to look.

Hi. I've created a silverlight applicatin in VS 2008. Now I've created a simple login control containg two text boxes & a Button. Now i've added this user control in the Page.Xaml page. In asp.net application, I've added a default.aspx page & put following code in the html part -
<%@ Register Assembly="System.Web.Silverlight" Namespace="System.Web.UI.SilverlightControls"
TagPrefix="asp" %>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div style="height: 100%;" id="g">
<asp:Silverlight ID="Xaml1" runat="server" Source="~/ClientBin/Debug/Vista Style Button.xap"
MinimumVersion="2.0.30523" Width="100%" Height="100%" />
</div>
now i want to access values of two text boxes in the Page_Load Event of the Default.aspx. Can any one help me?

Why do you want to do that? If you are using textbox in Silverlight, you should access those values from Silverlight. Why do you want to get those values from ASP.NET?

Hi All! I want to record audio using silverlight. can any one has idea about it?

I'm building my own WPF control. Once added to a Window in design mode the control needs to set some of its properties dynamically based on the Window. In code behind I'm doing this:
Foo = "Some dynamic Value";
So I don't loose the new value I want the XAML updated to:
< providercontrol x:name="Control1" foo="Some dynamic Value" >
Much to my dismay the XAML isn't updating. So far my attempts at this will update the property value in the Properties window but the XAML remains unchanged. Without saving my change to the XAML the value is lost when the Window is closed.
How can I change a property inside the control and have the XAML reflect that?

I'm a bit confused by your question. What exactly are you expecting to see changed in the XAML?
