I'm trying to find a way to get my tiles to dynamically size to the width of the panel (with ColumnsCount set by users) down to a minimum, then enable scrolling. 

If ColumnWidth="*" it displays correctly with a small ColumnsCount:


But with a large ColumnsCount it shrinks the tiles down below the minimum size of the contained control:



If I set ColumnWidth="Auto" it displays correctly with a large ColumnsCount:


But with a small ColumnsCount it displays them at their minimum size with a bunch of extra white space to the right:


Is there a way to get it to resize down to a minimum then scroll?

Thanks,
Louis

Dear Telerik support,
Please see this video: https://www.youtube.com/watch?v=Q4vtPcpiGcY

The code that I use to change the colors is:

                        StyleManager.ApplicationTheme = new Windows8TouchTheme();
                        var convertFromString = ColorConverter.ConvertFromString("#FFAF231E");
                        if (convertFromString != null)
                        {
                            var color = (Color)convertFromString;
                            Windows8TouchPalette.Palette.AccentColor = color;
                            //Windows8TouchPalette.Palette.EffectHighColor = Colors.Yellow;
                            //Windows8TouchPalette.Palette.EffectLowColor = Colors.Green;
                            Windows8TouchPalette.Palette.HighColor = Colors.White;
                            Windows8TouchPalette.Palette.InvertedColor = color;
                            Windows8TouchPalette.Palette.InvertedForegroundColor = Colors.White;
                            Windows8TouchPalette.Palette.LowColor = color;
                            //Windows8TouchPalette.Palette.MainColor = color;
                            //Windows8TouchPalette.Palette.MainForegroundColor = color;
                            Windows8TouchPalette.Palette.MediumColor = Colors.Red;
                            Windows8TouchPalette.Palette.ValidationColor = color;
                        }

Version of the controls: 2013.2.611.45

I have few questions:

1. Can you please tell me when i select a row how to change the Foreground on the text to white from the template? I not see it is possible but can miss something. In your documentation ( http://www.telerik.com/help/wpf/common-styles-appearance-colorizing-metro-theme.html ) not have a information where exactly all different properties apply the colors. What mean EffectLowColor? From the name means nothing as most of the all. The only way to know their meaning is to experiment to add different colors to see where what will be changed. The example in the documentation link is not helpful to understand this. And seems different controls understand by different way the template.

2. What Palette property change the RadRibbonView.QuickAccessToolBar from black to something else? I test all properties and no one from them have any effect on this black line.

3. Next situation is with your control RadRibbonView. When I click ApplicationButton and open Backstage you see there is white Foreground on white background on RadRibbonBackstageItem.
If I remove from the code above Windows8TouchPalette.Palette.InvertedForegroundColor = Colors.White; then we have gray Foreground on white background but this change the grid column header Foreground to gray. This mean both GridColumnHeader and RadRibbonBackstageItem Foreground depend on InvertedForegroundColor.

Something is not right here. When I move with the mouse over the GridColumnHeader the Foreground is change from white to black ( as expected ), but when i move over the RadRibbonBackstageItem the color is not changed from white to black as i will expect. When RadRibbonBackstageItem depend on InvertedForegroundColor i will expect same behavior as GridColumnHeader when move with my mouse over it but it not happens.

In same time the background on RadRibbonBackstageItem not depend on LowColor as GridColumnHeader Background.

This is what I mean the different controls understand the template by a different why. The idea on the template is when I change the color on one place this to apply on every other places not to add manually a Background or Foreground on few controls.

4. Can you please help me how to apply this template to MS Controls? Because it is not very good half from the program to have a different style.

Thank you in advance.

Best regards,
Saykor

As shown in the provided attachments the context menu is now over top of the selected item instead of being to one size of it.  This is with the 617 Q2 build.

Please address this.

hi,

I'm using WPF RadContextMenu and when I right-click the context menu gets opened at the left side of mouse click position, what should I change so that it opens on the right side from the mouse click position?

This happens for me on all the Telerik demos as well so can't find a sample that shows what to set.

I have tried DropDownPlacement to Left for RadMenuItems but it didn't make a difference. I've also tried setting the menu Placement to PlacementMode.MousePoint - still the same.

thanks!

Doing a very simple shapefile based map.  I can see the map in preview, but not when I debug.  shapefiles are in a folder called Shapes just off the project root.

  <telerik:RadMap HorizontalAlignment="Left" Center="40,-74" VerticalAlignment="Top" Height="500" Width="600">
            <telerik:RadMap.Provider>
                <telerik:EmptyProvider />
            </telerik:RadMap.Provider>
            <telerik:InformationLayer x:Name="informationLayer" >
                <telerik:InformationLayer.Reader>
                    <telerik:MapShapeReader x:Name="xShapReader"
                                            Source="pack://siteoforigin:,,,/Shapes/cb_2013_us_state_500k.shp" 
                                            DataSource="pack://siteoforigin:,,,/Shapes/cb_2013_us_state_500k.dbf"

I'm trying to set up my view model items with an IsExpanded property that I can use to expand & collapse their row programmatically. We previously did this with a TreeView pretty easily, but ended up needing the extra columns of a TreeListVIew so now we're trying to port over functionality to a TreeListView. Unfortunately I'm having problems getting rows to expand programmatically with a virtualized TreeListView.

I first tried using the IsExpandedBinding on the TreeListView itself:

IsExpandedBinding="{Binding IsExpanded, Mode=TwoWay}"

This successfully allowed my items to listen to when the user expanded/collapsed the item's row by clicking in the UI, but failed to ever propagate changes back to the UI when I modified my item's IsExpanded property programmatically.

My next attempt was to modify my TreeListView's TreeListViewRow's Style to binding the row's IsExpanded property directly to my item's IsExpanded property. This method almost works. The part where this fails is that my TreeListView uses virtualization, and any items not currently visible fail to update when their IsExpanded property gets modified via the binding.

So my questions are, does the IsExpandedBinding really support TwoWay? If so, what might we be doing wrong? If not, how can I get the row's IsExpanded binding to function when the TreeListView is virtualized?

Thanks!

Hello!

I have a RadRichTextBox inside a DataTemplate, and I have HtmlDataProvider inside RadRichTextBox.Resources section bound to it. But for some reason this does not work, error message is:
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=RichTextBox'. BindingExpression:(no path); DataItem=null; target element is 'HtmlDataProvider' (Name=''); target property is 'RichTextBox' (type 'RadRichTextBox')


I can bind provider with radrichtextbox after both controls are initialized, but I want to do that in XAML.
Is there a way to accomplish this task?

(Also I could not attach sample project, because only image files are allowed)...

Hi,

over the year more and more things have become "bindable" - a must have for MVVM.
What I still miss is Command Support.

Example - RadGridView.
I need special logic to store (insert / update) a row in the database.

What I have to do is handle the RowEditEnded (and if I need RowValidation) also the RowValidating events.

I solved this by subclassing the RadGridView and offering a "RowEditEndedCommand" and a "RowValidatingCommand" as ICommand.

Now I can handle the things without code behind.
Something like <xx:MyGridView RowEditEndedCommand="{Binding MySpecialCommand}"...

And what I got is a thing like a Button - I still can handle Events (OnClick) - but I can also bind a Command from my VM.

I don't know if I'm the only one with this need....

Hi!

I was searching how to do the redistribution of my application with telerik control in your website and I didn't found anything. In the future, when my application will be finished, I will have to give it with telerik control at my customers, but I do not know what I should do.

Please, can you explain me how to do?

Thanks, 

My application puts up a login dialog before showing the main window.  If the login information is not correct, it calls .Close() on the main window to shut down the application.  Everything works except the RibbonView. 

If I call Close() during the main window Loaded event, the RibbonView throws a null handle exception.  I tried making the window start out invisible, and then showing it in the MainWindow ContentRendered event, but then the window (including the RibbonView) shuts down correctly, but with good login, the RibbonView does not show until the window is restored from maximized to be not full screen.

Be advised that the null handle exception does NOT happen when running in Visual Studio, only when running the built application.  Is this a known bug, and is there a workaround?  Thanks.
