No. Windows XP handles all our transitions just fine. Do you have a good video card ? Are your drivers up to date ? What are you doing exactly ?

I'm new to all the wpf developing so I'm building a very simple animation. There is a rectangule with a gradient on the screen and I move it from left to right. That's all.
The size of the rectangule remains the same, only it's position changes.
I'm using the Expression Blend to create the animation and the see the XAML code. The animation looks generated is this one:
<Storyboard x:Key="TextAnimation">
<ColorAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="{x:Null}" Storyboard.TargetProperty="(Panel.Background).(SolidColorBrush.Color)">
<SplineColorKeyFrame KeyTime="00:00:02" Value="#FFFF0000"/>
</ColorAnimationUsingKeyFrames>
</Storyboard>
<Storyboard x:Key="testAnimation">
<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="rectangle" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.X)">
<SplineDoubleKeyFrame KeyTime="00:00:00" Value="0" KeySpline="0,0,1,1"/>
<SplineDoubleKeyFrame KeyTime="00:00:01" Value="340" KeySpline="0,0,1,1"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="rectangle" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)">
<SplineDoubleKeyFrame KeyTime="00:00:00" Value="0" KeySpline="0,0,1,1"/>
<SplineDoubleKeyFrame KeyTime="00:00:01" Value="225" KeySpline="0,0,1,1"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
As you can see, the propertys being changed are the X and Y positions.
The problem is that as the rectangule moves throught the screen, the borders flick( you can see how they are been drawn very quickly) and this gives a very shaby effect.
Is there any other way to do this? All the examples and libreries I've found have the same problem.
Again, thanks!
Cheers

I am beginner, trying to understand Silverlight2Chat application. I followed instructions on Build a Silverlight 2 Web Chat Application[^]to create Silverlight2Chat project in visual studio. My solution explorer show the project exactly as in the picture on the above link.
In the web.config file I changed the connection string as follows:
<add name="LinqChatConnectionString" connectionString="Data Source=[STUDYMG];Initial Catalog=LinqChat;Integrated Security=True;" providerName="System.Data.SqlClient"/>
I created two records in dboUsers, and one record in dbo.Room tables.
Now to see how it works, I right click on Silverlight2Chat in the solution explorer in Visual Studio, then choose 'View in Browser', It shows me the login page, I enter credentials and then click on login button, but nothing happens.
I also did 'View in Browser' for Silverlight2ChatTestPage.html, which also shows me the login page, but nothing happens when I enter credentials, and click on login button.
What am I missing?

You need to actually run the app instead of just viewing it in a browser.
Try choosing Debug/Start new instance or hit the F5 key.

I did try running the app with F5 key and ctrl+F5. but still nothing happens when I click Login button after entering credentials.

I browsed quickly over that article....is there a WCF service involved?
If so, do you have that running as well?

ValidateUser method uses WCF service to validate the user name and password entered by the user. I am currently running this app from within Visual studio. How do I run the WCF service?
I appreciate for your help.
Thanks.

I haven't seen how the projects are configured, but it is possible to
run both the server and client sides at the same time in the debugger.
Right click the server project, choose Debug/Start instance. Then do the same
for the client project.
Beyond that I can only guess without downloading the code...I'll see if I can do that...

Debug/Start instance starts the app as described in my previous msg, but does not work.
I opened server explorer in visual studio 2008, and expanded 'services' tab. It does not show WCF service running. How do I make this service run?
Thank You.

You have TWO APPS to start.

Ok. I started both apps in debugger and logged in. Now it is working, and shows the msgs that two users sent through chat. But, it does not show the text box where msg is being typed, looks like the screen is incomplete. I checked the code on Chatroom.xaml. It does have a textbox named TxtMessage, which looks like the place where user types in a msg.
<TextBox x:Name="TxtMessage" TextWrapping="Wrap" KeyDown="TxtMessage_KeyDown"
ScrollViewer.VerticalScrollBarVisibility="Visible"
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
Width="360"
BorderThickness="2" Margin="0,0,10,0"/>
But, this text box is not seen when I start the app and login. I logged in as two different users from two different browser windows. Both could pass msgs, but could not see the text box where msg was being typed. 
Thank you. Greatly appreciate your help.

TxtMessage is the TextBox where messages are typed.
How were you able to pass messages without seeing the textbox?

I did not see the textbox, but just typed something and pressed 'enter'. It appeared in the msg box above.

Interesting.....I can see it fine.

What browser are you using. I tried on IE8.0 where it shows msg box, loggedin people, but no textbox where msg is typed.
But, if I launch it using Firefox3.0.11, the page is completely blank.

I see a blank page when I launch the web app, which as far as I can tell
from a quick look at Chatroom.aspx (the default page), shouldn't be blank.
So instead of debugging that, I just (on the blank page) change "Chatroom.aspx"
to "Silverlight2ChatTestPage.html" and that one shows the silverlight app.

In Chatroom.aspx, change the body to this
<body style="height:100%;margin:0;">
<form id="form2" runat="server" style="height:100%;">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<div style="height:100%;">
<asp:Silverlight ID="Silverlight1" runat="server" Source="~/ClientBin/Silverlight2Chat.xap" MinimumVersion="2.0.31005.0" Width="100%" Height="100%" />
</div>
</form>
</body>
and it shows up like it should.

While it's great that you got help from Mark, you really should have posted this on the forum for that article. You don't post article questions in the general forums, because you are going to cause problems for other people who have the same issue with this application. If the questions and solution were in the forum for that app, then others could see how it's been resolved - now, they are on their own; not knowing that this issue has been solved already, and it's not an intuitive step to go searching the other message boards looking for a solution.
In future, if you've got a problem with an article, post your questions with that article and give the author a chance to get to know what problems they have.

I saw the discussion link on that article and it has a question where user says 'can not have it running' but no one answered it. So I tried this forum and got help. Will remember your suggestion next time. Thanks to Mark for helping me.
I am a beginner trying to learn.

------------row1----- [up]----[down]---------
-------------row2------[up]----[down]---------
-------------row3------[up]----[down]---------
please consider these three rows as the rows of the grid, now if i want to move the row3 up,i insert a new row between row1 and row2
-------------row1----- [up]----[down]---------
-------------NEW ROW-- [up]----[down]---------
-------------row2------[up]----[down]---------
-------------row3------[up]----[down]---------
then copy the values of row3 into the new row.....
------------row1----- [up]----[down]---------
------------row3----- [up]----[down]---------
------------row2----- [up]----[down]---------
------------row3----- [up]----[down]---------

The best way to modify your rows, is to use an ObservableCollection and to modify the data source.

Hmmmm..... i tried out observablecollection....
it does work (sort off).... i mean the row move up and down... but only in the view.... as i have been using indexs to point out a single row, and if i move the first row to the grid to the second line the [up] button of the previously first row that had been disabled (the up button of the first row and down button of the last row are disabled) stays disabled....
so i land up in the great index mess where now my row2 which is on the top has both its up and down buttons enabled and my row1 has no up button!!!!
hope i didnt confuse u..... please help me out....

Please let me know are you using any itemsource for grid or doing through code behind can you explain XAML part of Grid:
Ex:
Controls1:XamDatagrid x:Name="LstCompRelationship" ItemSource="{Binding ContactJobFunctions}"
then it would be easy to give answer accordingly.

Hi,
It is possible to have a common class for two windows? i.e is it possible to have the event handling code common for both the windows as my windows are almost alike.
Thanks
