Okay, after too much fiddling around, figured out part of the problem. The margin on the scrollviewer element of the tabcontrol was wrong (and is still kinda wrong I think), and the margin on the tab item needed to be set in the !IsSelected state. I now have the proper separator line under unselected tabs, and no line under the currently selected tab. Now all I have to finger out is the tot and left border of the tab (which also might be a margin problem.

I need to define a customized event which detects whether the border of one UI element crosses the border of the other UI element.
Make this assumption that both UI elements are on a Canvas, and they have the relative coordinates toward the boundary of the Canvas which are Canvas.Left and Canvas.Bottom.
My initial thought was to create a function which checks the relative coordinates of these two elements and raise the event whenever their coordinates are identical. Then, I realized it was rather awkward because each element has its area and it can not be considered as a pixel.
I have contemplated this puzzle for quite some time but still I can not come out with anything. Would anyone be kind enough to help me out on this I will be grateful.
Thanks in advance

I'm not sure exactly what you're looking for...
For rectangular elements, if you don't want to code it yourself, you
could probably use the Rect structure and its Intersect() method...if
the method returns Rect.Empty then the elements don't overlap.

Thanks Mark for your information.
I did a little bit of research on the method you provided me, and I found out this Intersect() method belongs to a GDI+ rectangle structure and it's not supported in WPF shapes. Are there any other methods which can substitute this one?
BTW, you are right about what I am looking for. In my program, I need to use an event to detect the intersection of different WPF UI elements in order to process some task once they cross over with each other.

You looked at the wrong one.

I think I am working on something somewhat similar and while I am probably ahead of you on this one, I am a long, long way from done. A screenshot of where I am now is shown below.
Basically, the way I am doing it, I have three planes, one for each axis. I also have a two dimensional user control that does two dimensional XY graphs. I am using three VisualBrushes, one for each plane and passing an instance of the two dimensional usercontrol into the constructor of those VisualBrushes. I am then using those VisualBrushes to texture the three axis planes. For the points, I am creating spherical meshes and positioning them inside of the XYZ chart area.
When I finally get done with this whole thing, which won’t happen anytime soon, I will do one or more posts on it on my blog with source code. However, I am so far from done that that may be a while. I won’t publish the code that I have at this point in time because it is so crude and filled with quick and dirty workarounds that I don’t want it on the web in its current form. I hope this helps at least with the getting started part though.

Any third party control for Data Grid with all the event as in WINFORM DataGrid for WPF?

There's one in the WPF Toolkit[^].
The toolkit is where you can get your hands on controls before they make it into the
.NET framework.

Infragistics WPF control. We are heavily using it.
Try that.
Or else, in codeplex, you will get WPF datagrid.
Search in google for the same

Hi, i am trying to make a WPF listview control that contains a gridview. The problem is when i run the application, at one time user can select just 1 row of the grid. If user selects another row, the previous row selected is un-selected automatically i have tried using cntrl+ mouseclick still i can not select multiple grid view rows.
What exactly i want to do is, i would like to display gridview's coloumn(0) value of all the selected rows(concatinating each value) in the some textbox. Can anyone Please help?
My code is:
<DataTemplate x:Key="FirstCell">
<StackPanel Orientation="Horizontal">
<CheckBox IsChecked="{Binding Path=IsSelected,
RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListViewItem}}}" >
</CheckBox>
</StackPanel>
</DataTemplate>
<ListView
ItemsSource="{Binding}"
IsSynchronizedWithCurrentItem="True" Name="ListView1" Margin="218,83,25,88"
ScrollViewer.CanContentScroll="True" ScrollViewer.HorizontalScrollBarVisibility="Disabled"
SelectionChanged="ListView1_SelectionChanged" SelectionMode="Multiple">
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
<EventSetter Event="GotFocus" Handler="Item_GotFocus" />
</Style>
</ListView.ItemContainerStyle>
<ListView.View >
<GridView x:Name="Grid1" >
<GridViewColumn Header="Code" Width="70" >
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBox Text="{Binding Path=Code}"
Margin="-6,0,-6,0" x:Name="Codename"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Discription" Width="70" >
<GridViewColumn.CellTemplate>
<DataTemplate >
<TextBox Text="{Binding Path=Description}"
Margin="-6,0,-6,0" x:Name="Descriptionname" />
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn CellTemplate="{StaticResource FirstCell}"
Width="30"/>
</GridView>
</ListView.View>
</ListView>

Your code works for me. Multiple selections work - no CTRL key necessary.
Only change I made is fixed the broken FirstCell data template (it wouldn't compile
so I removed the binding from the checkbox) and removed all event handlers since you didn't
provide the code.

Always use
SelectionMode="Extended"
and not SelectionMode="Multiple"
Try this and vote me

We are using WPF Dock as Prism Extension in our project. That extension can be downloaded from CompositeWPFContrib website. Currently, we are having some issues with Dock and Popup control. Please read more details about that problem in steps to reproduce.
http://michaelsync.net/demo/CALApplication.Shell.doc
Note: Please download the attachement and change the file extension "doc" to "zip".
1. Run the application
2. Click on Menu #1
3. Select "Customer Details"
4. Click on "Open Pupup" button
5. Click on "Open View 2" (View2 will be opened)
6. Click on "Customer Details" tab
Observe: Tab will be automatically moved back to "View2".
Note: It happens only when we are launching the VIew2 from Popup. If we move the command " Command="{Binding LaunchView2Command}"" to button above Popup, it won't happen. Not sure whether there is any relationship between Popup and Dock or Popup and Prism.

I'm not sure what you're asking here....if the button is a child of the
stackpanel, and the button has a name, why are you unable to just use the
button by name?
Can you post a simple example of the xaml/code-behind involved to make it more clear?
