Hello,
I am using your tileView in my app.
I am using a tile that every item in it is itself a tileView of user controls.
I am having an exception when I switch the itemsource of the outer tile (which effects the inner ones as well as they are binded to it).
The big tile's itemsource is binded to a treeview's itemsource.
Whenever there is a change in the treeview's collection (the tree has checkboxes the decide which tiles will be visible) I am updating the binding manually (getting the binding expression and updating).
In a converter I convert the collection (a ListCollectionView of the viewmodel class of the user controls, filtered into groups) that I got from the tree to a collection that contains only the groups that are checked in the checkboxes (the groups are the outer tileItems).
In the converter I copy the collection and delete only the groups that are unchecked (not supposed to be visible).
The user controls within each group are binded to a boolean property that tells the visibility of the items (with a converter).
The problem is that sometimes when I update the binding, I get notification of a tilePositionChanged of the inner tileView (that contains the user controls).
The position that I get is -1, and that value does not come from my viewmodel (I checked).
Than I get an exception thrown because the tileView tries to put an item's column property to -1.
This does not happen every time, only when checking or unchecking an item and than I refresh the binding of the bigger TileView(which the inner ones are binded to).
I hope you have enough data.
unfortunately i can't attach the code.
Thank you in advanced,
Tamir.

I'm using WPF/MVVM
For all parent rows that have Employees.Count > 0, I need to have the row details expanded. Can you tell me how to do this. Again, I'm using MVVM and NOT using events. This needs to be done with binding.
Thanks

Hi all,
I currently have a problem with applying Style for TextBlock when TextBlock is in RadDocking control. I have a simple example below.
- The app will use Windows8Theme
The TextBlock is set with FontWeight Bold.
In the designer it was correctly displayed

But in runtime it was not
http://i.imgur.com/F1Cchw1.png
I think that setting ApplicationTheme in App() has overwritten the Style of TextBlock.
Question: What should I do to keep FontWeight of TextBlock from overwriting by StyleManager?

Hi,
I am having multiple issues around the mini tool bar, the main issue is that when a user uses the select all command(Ctrl + a) this tool bar doesn't show.
Second issue is the tool bar visibility is very temperament so is there anyway to make it permanently visible when there are selected items - and possibly add the ability to move/dock this.
Any help would be appreciated.
Thanks
-Chris

Hi Telerik,
I want to adjust all my axis values on a radcartesianchart.
See the attached image "before changing y-axis values.JPG" and "after adjusting the y-axis value.JPG".
These images shows a change in the y-axis which is done by draggin the horizontal line up or down.
Is it possible to do something like this using telerik?
Best regards,
Jeppe

Hi,
I have this scenario: I want to create from code behind some RadDiagrams, then export every diagram to a single PNG image without open and display the raddiagram.
Below there is my two solutions of code which don't work. IN particular, the stream is always empty.
1)
var myGraphSource = new GraphSource(); //this contains a list of shapes and connections
var diagram = new RadDiagram();
diagram.GraphSource = myGraphSource ;
diagram.SelectAll();
using (var stream = new MemoryStream()) {
diagram.ExportToImage(stream, margin: new Thickness(0,0,0,0), backgroundBrush: new SolidColorBrush(Colors.White));
image = stream.ToArray();
}
2)
var diagramViewModel = new DiagramViewModel(myGraphSource);
var diagramView = new DiagramView();
diagramView.DataContext = diagramViewModel;
using (var stream = new MemoryStream()) {
diagramView.diagram.ExportToImage(stream, margin: new Thickness(0,0,0,0), backgroundBrush: new SolidColorBrush(Colors.White));
image = stream.ToArray();
}
In both cases the code doesn't work and in the last scenario, I' ve bounded the GraphSource in the xaml. Is there a way to get my issue????
Thanks
Ciro

Hi,
I've submitted the following already as a pre-sales question, but I really need support fast so I'm also submitting it to the users. Please let me know if anyone knows how to fix this bug, or if it's truly something with the Telerik GridView control.
Here's a link (http://1drv.ms/1hm6fJs) to my compressed solution on my OneDrive which I've shared. The following steps will cause the test program to crash.
1. Run the application.
2. Scroll to the right so the WorldSeriesWins column is visible.
3. Click the filter icon button and set the filter to be "> 27" in the pop-up window
4. Click the "Filter" button and all rows will disappear (as expected) and the grid will scroll the whole way back to the left.
The Filter pop-up windows will still be visible and at this point click the "Clear Filter" button which causes the application to crash.
The bug seems to occur if the column is not visible. If you were to scroll the scroll bar back to the right so the WorldSeriesWins col was visible and click the "Clear Filter" button it would not crash.
Thanks!
