Custom background in border?

I started with the Telerik WPF Q2 2010 examples.
I went to Controls -> DATA -> GridView -> Appearance -> Custom Row Layout

I am using a slightly modified version of this now. What I want is to change the four gradient stops for the main row background dynamically based on object properties of the binding. The problem is that my template is 75 lines long and I think it seems very inefficient to duplicate this six times (for siz possible gradient values) and use a TemplateSelector. Instead I'd like to modify the border background property.

Here's a small snippet of code:

<ControlTemplate x:Key="TCCustomRowTemplate" TargetType="telerik:GridViewRow">
    <Border x:Name="rowsContainer" Background="#FF525252" Padding="8,8,8,0" >
        <Border x:Name="selectedRow" BorderThickness="1" BorderBrush="#FF000000"
            Background="{StaticResource TC_INRowBackgroundSelected}>

How can I modify this background to be a different static resource dependant on my object?

Tab Scrolling - One Tab at a time

Hi
I've modified the TabControl but would like to force the scrollviewer repeat buttons to scroll one full tab at a time but cannot find a way to do this.

I thought I might be able to add something like Command="ScrollBar.LineDownCommand" to the repeat button - no joy though!

Any help would be much appreciated.

Adding OutlookBarItems to OutlookBar and displaying the content of the OutlookbarItem

Hi,
I am trying to Wrap RadOutlookBar and make MYOUTLOOKBAR so that i can expose only few properties in MYOUTLOOKBAR.
In this senario i need to add radoutlookbarItems to MYOUTLOOKBAR.

Even if i add MYoutlookbarItem to MYOUTLOOKBAR ..In xaml i was able to look at the change.
But in design i dont see any Item getting added to the Outlookbar.

if add content to this Newly added MYOutlookBarItem from properties tab, i get an error message saying that

"Property Value is not Valid"
(in detail: Property "content" does not support string to value conversation)

How to add items to outlookbar so that the items of the outlookbar should support exposed properties of radoutlookbar control?

Here is an example code...for Items property of MyOutlookbar.cs

#region

Property: Items

private MYOutlookBarItemCollection _items;

public MYOutlookBarItemCollection Items

{

get

{

if (_items == null)

{

_items =

new MYOutlookBarItemCollection ();

}

return _items;

}

}

#endregion

The above code exposes the items property in MYoutlookbar

MYOutlookBarItemCollection.cs will be a separate will which contains
public class MYOutlookBarItemCollection: ObservableCollection<MYOutlookBarItem>

{

}

Here is an example code...for content property of MyOutlookbarItem.cs

#region

Property: Content

public object Content

{

get { return (object)GetValue(ContentProperty); }

set { SetValue(ContentProperty, value); }

}

public static readonly DependencyProperty ContentProperty =

DependencyProperty.Register(

"Content", typeof(object), typeof(MyOutlookBarItem),

new FrameworkPropertyMetadata

{

PropertyChangedCallback = (obj, e) =>

{

(obj

as MyOutlookBarItem).UpdateContent((object)e.NewValue);

}

});

private void UpdateContent(object sel)

{

OutlookBarItem.Content = sel;

}

#endregion

Can you guys help me..

Thanks,

ItemTemplateSelector Not working

Hello,

The ItemTemplateSelector for the RadTileView does not seem to be working. I can set the property and it is set correctly, but it does not run the SelectTemplate Method. I am using the current Build (0714).

Would someone send code that works with this in the current version?

Thanks,
Matt

Font Colour based on Value

I currently have a Loop going through a cube which returns the name (Caption) of its items.
However as this is an OLAP cube I want to distinguish between user defined and attribute hierarchies. I thought the best way to do this would be to give each one a different color (so give User Defined Hierarchies a blue font and Attribute Hierarchies a red font for example).

I thought this would be simple but the method I tried below threw alot of errors, while other methods turned all of the items a particular colour rather than just the items I wanted.

Has anyone got an idea of how I could change an items colour depending on its value??

Window1.xaml.cs

foreach (Hierarchy hierarchy in dimension.Hierarchies)

{

Dimension HierarchyItem = new Dimension();

HierarchyItem.Caption = hierarchy.Caption;

DimensionItem.SubDimensions.Add(HierarchyItem);

HierarchyItem.IsDraggable = true;

if (HierarchyItem.Caption == "Account Number")

HierarchyItem.Caption = Brushes.Red)

else if (HierarchyItem.Caption == "Customer Number")

HierarchyItem.Caption = Brushes.Blue)

Percentages in Graph

I am using percentages in my graphs but the y-axis label as well as the item labels show 100% as 100.00% or 95% as 95.00%. Is there a way to make it show only whole numbers?

Thanks,

Draggable Windowless Application

Well, my question is not related with the radwindow but I hope you guys can help :)

I have a windowless WPF application and I want it to be draggable by the users.

I can make it dragglabe by returning HTCAPTION in the WM_NCHITTEST message like this:

protected override void OnSourceInitialized(EventArgs e)

{

HwndSource hwndSource = (HwndSource)HwndSource.FromVisual(this);

hwndSource.AddHook(WndProcHook);

base.OnSourceInitialized(e);

}

private static IntPtr WndProcHook(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handeled)

{

if (msg == 0x0084) // WM_NCHITTEST

{

handeled = true;

return (IntPtr)2; // HTCAPTION

}

return IntPtr.Zero;

}

But then, the click event of the buttons inside the application doesn't work...

-----

When I add "DragMove" to the "MouseLeftButtonDown":

this.MouseLeftButtonDown += delegate { DragMove(); };

Then the problem is, if I click one of the buttons, I get an InvalidOperationException.

User interface :)

Does anyone have something in mind for this?

How can I center RadWindow?

Good morning, afternoon, evening,

I am having trouble figuring out how I can center a RadWindow using WindowStartupLocation.CenterOwner when I open it from a non-wpf application.

I used the following code in my winform app to open a dialog that is a System.Windows.Window. When I convert it to a RadWindow, it doesn't work and I am at a loss as to how to duplicate functionality.

var dlg = new MyDialog();

System.Windows.Interop.

WindowInteropHelper hwndHelper = new System.Windows.Interop.WindowInteropHelper(dlg);

hwndHelper.Owner =

new IntPtr(Globals.ThisAddIn.Application.Hwnd);

dlg.ShowDialog();

How can I center the window?

Please assist.

Thanks,
Alan

PS. I have a support agreement but decided to post here so that others might benefit from response.
