Create a couple of RadPanes in one RadPaneGroup so that it shows the tab headers. Create another RadPaneGroup with a RadPane.

Put a RadTreeView in the first RadPane, populate with some items.

OK, select 1 of the TreeView items.

1. If you click on the RadPane header in the separate group to activate it, the selected TreeView item will switch to "SelectedUnfocused" state (turns gray).

2. Click back on the TreeView item to focus it again.

3. This time, click on the other RadPane tab in the same group. Click back on the pane tab header with the TreeView. In this case, the TreeView item is still blue (in a SelectedFocused state). But it actually is not "focused". At least not keyboard focused, so it should be gray.

Code I found :)

If you look in Docking.PaneHeader.OnMouseLeftButtonDown(), when the user selects a RadPaneGroup, Focus() will be called on that group. That is why the RadTreeViewItem turns gray in the first test.

But no such "Focus()" call can be found when only a RadPane is activated. To fix, I put a Focus() call in RadDocking.ActivePaneChanged event, but you may want to do it differently. :)

Hello All,
     I have been tasked in a WPF/MVVM application to setup a TreeListView that shows some "Property/Value" pairs.  For most of the properties, the value should be a simple textbox, but for some of the particular properties, the values should be displayed as a dropdown selection.  Is there a way to get this done.  I'm starting down the path of in the table that stores these property/value pairs, have a column that designates what type of "Value" cell show be displayed, the by using that setting up a CellEditTemplate to properly configure the cell as either a textbox or dropdown...  Having never created a CellEditTemplate before, I wasn't sure if this is possible or even the correct path to venture down...  So, there's my dilemma/question...  If this is the correct path, is there a good example of how to get this done???

Thanks in advance,

Hi people,

I have problem with RadGridView and background color: I can't set it ! I have a MVVM application and the grid is bind with observable collection; all my data are displayed correctly:

Now I want to color the row and bind it to property named UserInput (boolean) using converter like this:

But it doesn't work. I tried:

1)

Result: all my rows disappear!

2)

Result: my single cell disappear.

3)

OR

Result: the color of cell is thedefault, no change.

Where is my error? How I can do it?

Thanks a lot.

Is there a way to initialize a map to a specific position without having to see the map rapidly pan and zoom?

I have a set of items in a VisualizationLayer and I would like to display those items on the map without scrolling and zooming. The layer is bound to a list in the xaml.

Currently, I set the bounds by calling GetBestView() on the VisualizationLayer to get the precise boundaries. This works, but the map starts at coordinates 0,0 and then scrolls and zooms. It does this for several seconds - the appearance is very annoying to the user. 

I would like to be able to set the bounds directly and have the map go straight to the area without scrolling and zooming. It may be that I am not setting the bounds at the appropriate time?

Is this even possible?

Hello,

I started using this custom polyline tool (http://www.telerik.com/forums/polyline-tool) but somehow it does not receive the keyboard input (pressing the Enter key to 'stop' the drawing of the polyline). 

The exact same happens with the default PathTool (which should respond to the ESC key as can be seen in the Demo application).

What could this be? I did not find any setting which has anything to do with handling keyboard input.

Best regards,

Douwe

I have a TreeListView control that I need to expand and collapse rows via the view model. The problem is the TreeListView control will sometimes update after updating the view model but not always. Or sometimes the TreeListView control will update after a few seconds. If I scroll to the bottom of the TreeListView control and back it will always refresh to match the correct view model values. 

I have put debug statements next to the OnPropertyChanged calls and it always seems to be firing correctly. Since the TreeListView control will sometimes update it seems like it is not a binding issue to me. It's configured to use TwoWay binding. INotifyPropertyChanged is implemented in the view model. It feels like the TreeListView is not always getting the OnPropertyChanged event but I don't know why it would get it sometimes and not other times.

I am thinking I could implement a way to force the TreeListView control to refresh any time the property that IsExpandedBinding is bound to changes but this does not seem like a good solution to me.

Any thoughts as to why this may occur?

I'm using RadGridView with GridViewMaskedInputColumn like that:

<telerik:GridViewMaskedInputColumn DataMemberBinding="{Binding RealCurrent, Mode=TwoWay}" DataFormatString="n2" Width="85" Style="{StaticResource BlueGridViewColumnStyle}" Header="{x:Static commonResources:ControlResources.RealCurrent }"/>

This is great, because in the column I see numbers rounded to 2 digits after decimal point.

But when I want to edit it and I delete whole number I cannot type decimal point...

I can fix it by adding Mask="#1.2", but than I can type only one digit BEFORE decimal point and I see underscore as a placeholder. I don't want to have any limitations for that (user should be able to place 0.55, 45.8, 131645651654.1 or whatever) and any underscores. How to achieve this?

Hello Telerik community,

First post for me here :)

I would like my diagram (placed in a userControl) to react to some events in my MDI application. (events done in other usercontrol, like clicking on a portion of a text would select the text-corresponding box in the diagram)

The problem I have is that when I set my:

My diagram userControl gets the focus and the user can't type text anymore.

I would like to be able to change the selected item in my diagram without changing the application focus.

Any idea to achieve that? 

Thanks a lot!
