Hi,

I'm using ScheduleView to load custom appointments with the Load on demand features. The appointments load fine, but whenever I scroll backward or forward in time (e.g. previous/next week or month) the calendar scrolls back to the top, instead of staying at the time it was scrolled to before navigation.

This also occurs in the RadControls demo; just navigate to Controls -> Data -> Schedule View -> Features -> Load On Demand. Now click Week view. Scroll down to 18:00. Now click the right arrow to navigate to next week. The view scrolls back to the top at 0:00.

Any ideas on how to fix this? I found no method to manually get and set the scrolling position either.

I have been looking and trying for hours to print a telerik gridview. I succeeded in printing, in about the same way as described at http://blogs.telerik.com/vladimirenchev/posts/09-12-28/how_to_easy_print_and_print_preview_with_radgridview_for_wpf.aspx, but this causes the last row on each page to be splitted in half. The upper part of the row is at the end of page 1 and the lower part of that row is at the beginning of page 2. This is unacceptable.

How can I print the gridview in a decent way, without rows being splitted over two pages?

 

Hello,

I don't speak English very well, but I have a question about the API WPF Telerik.

I would like to know if it's possible to draw on charts?

The user must be able to draw a rectangle on a scatter series using the mouse.

This rectangle will be modified in width. The height will be automatically adjusted based on the average of selected points in the rectangle.

We would like to know if this is feasible or not via the API WPF Telerik and if so using what events?

Best regards,

Sorry guys, as it turns out someone had forgotten to put Mode=TwoWay in our control wrapper's consumer code.

Hi!
We're testing telerik maps trying to know if we can develop our requirements with them. We have found an error / incompatibility that we can not understand. We installed Dbf Viewer 2000 (trial) because we need to modify DBF files.
Dbf Viewer 2000 creates an association to Dbf Files that causes telerik maps (the ones that use data source files) to crash. The exception is this:

We have found that this is happening only when relative uri to resource is used. If we remove folder .dbf in HKEY_CLASSES_ROOT of registry maps don't crash.

We can not use absolute paths and we can not control the software installed on client's computers so there is a risk that maps crashes with any software doing the same with data source files.

You can try this with telerik demos.

Hi,

I have a grid like:

<telerik:RadGridView Name="patientsGridView" SelectionMode="Extended" ItemsSource="{Binding Patients}" SelectedItem="{Binding SelectedPatient}" AutoGenerateColumns="False" IsReadOnly="True" MouseDoubleClick="patientsGridView_MouseDoubleClick" RowIndicatorVisibility="Collapsed" SelectionChanged="patientsGridView_SelectionChanged" GroupPanelStyle="{DynamicResource GridViewGroupPanelStyle1}" >

I need the width of the grid - but ActualWidth is always 0. How can I get the width of the grid?

Hello everybody,

is there a way to identify the RadPaneGroup which is positioned in the lower left corner of the docking area? In my application this is the place where dynamically added pane should be shown.

I already read in another thread that the method RadDocking.GetDockState does not work properly.

Kind regards

Uli

Hi there,
    I am looking for a way to bind a collection of objects inside a TreeListView Grid column. I am able to bind to all of the objects in my hierarchy and have them displayed correctly in the TreeListView Grid. My Object model is something like this

NoteObject
        Text
        DateCreated
        DateModified
        Collection of Sub Notes ( of type Note )
        Collection of Flag Objects

Flag Object
       text
        type
    

The TreeListView Grid correctly displays the object hierarchy but I do not seem to be able to bind to the collection of Flag Objects. I would also like to use a converter on the Flag objects to change the background color of the cell based on the Flag Type. Could you send me an example of how to do this?

Thanks

Hello,

I have pretty much the same problem describe in that post : http://www.telerik.com/community/forums/wpf/gridview/rowdetailstemplate-and-text-wrapping.aspx .

Inside my RowDetails I have a control with some textblocs (set to warp). I dont want the horizontal scrollbar, to make my textblock warp.

The difference with the previous link is that I dont want to set the RadGridView width to a constant value. (to follow the window size)

I want the RowDetails width to be the same as the RadGridView width. I've set the ScrollViewer.HorizontalScrollBarVisibility= to "Disabled"

So I tried to bind the MaxWidth of my control inside the RowDetails value with RadGridView but it doesnt work (textblocs don't warp and horizontal scrollbar is still on)

this is my code :


Thanks for your help!

Regards.

Hello Telerik Team,

I have a RadOutlookBar, in which is currently one view that inherits from RadOutlookBarItem. In that view I overrided the OnIsSelectedChanged-Method from RadOutlookBarItem.
In the view, that contains the RadOutlookBar-Control, I added an eventhandler to the event PreviewSelectionChanged. So when I started the Application with the View, following methods are called:

1. OnIsSelectedChanged of the RadOutlookBarItem (oldvalue=false, newvalue=true)
2. The event PreviewSelectionChanged of the RadOutlookBar is fired (and certainly my eventhandler is called)

And if SelectionChangedEventArgs.Handled is set to true
3. OnIsSelectedChanged of the RadOutlookBarItem(oldvalue=true, newvalue=false)

Why is OnIsSelectedChanged called before the PreviewSelectionChanged-Event is fired?

Further Question:
If I click on the unselected OutlookBarItem, at first PreviewSelectionChanged from OutlookBar ist fired, if the Handled-Property is set to true, the OnIsSelectedChanged-Method of the Item ist called twice (first time with newValue = false, the second time with newValue = true)

Why is the OnIsSelectedChanged-Method called twice?
