Hi

I've just started using Expression Blend for UI design, instead of using the UI editor in VS2010. However, the Radcontrols in my project are not rendered in the Blend designer window. They appear as blank boxes. Regular WPF control render correctly however.

I've tried creating fresh projects from scratch and the same thing happens - no rendering of the Radcontrols, but standard WPF controls show up ok.

Is this expected?

Hi, I'm using Telerik RadControls for WPF v.2012.3.1017.45 and use RadGridView in the following configuration:

(columns are ommited, they are just databound to simple properties of one object).
Even simple mouse over causes serious peromance issues (up to 30% CPU usage from gridview application only) and bad user experience. When I moving over any other part of application - CPU usage is around zero. Any idea how to fix this? 

It seems odd that the larger unit time scale is 'inside' the finer granularity scale:

From top to bottom, it seems like it would make more sense for the scales to be flipped.  Instead of progressing like this:

Hour
Day
Week
Month

Wouldn't it make more sense to be:

Month
Week
Day
Hour

This way the mouse over effects would be more intuitive and rather than double-clicking on the lower one to expand the selection a single click is all that would be needed.

Since this is not the default layout, is this achievable by altering the template or will code need to be changed?

Hi,

 

I am using the radmap and placing  items onto the information layer using an example you provide. The items are an observable collection of the mapitem class:

 

Private items As New ObservableCollection(Of MapItem)()

 

This works well, but how would I get the best view for items created using this method where the items contain only the latitude and lonitude.

 

Regards,

Joe

I have a RadDataForm with a number of DataFormDataField. They are bound to an object of a class that implements IDataErrorInfo, and when a field control validation, it's surrounded by a red box and an error message is displayed at the bottom of the form, prefixed by the DataFormDataField's label.

I have three problems:

1. What if the label I want to display in the form isn't the label I want to display with the error message?  I have a couple of controls where I want the label to include a closing colon, and that results in two colons in the error message.
2. What if the control is not a DataFormDataField? The error message for these seems to display the name of the property it is bound to - and that's usually not what I want.
3. I have added BindingGroups to a number of GroupBoxes on the form, that return errors if something about the group is wrong. (None of the fields in the group have been selected, etc.) These display an error message that just has a colon, with no label name at all.

Seems like these are all different aspects of the same problem. Where does the form's error message display look, to get the names it includes, and how can I override this so as to use the labels I choose?

I have a GanttView on a tab control.  After I set the task source for the GanttView I use ScrollingService.ScrollIntoView to scroll the first task in the list into view.  This works great if the GanttView's tab is currently selected and everything is visible.  If the GanttView is not visible it throws a NullReferenceException.  I tried to change the code to only scroll the first task into view on the IsVisibleChanged event.  I still get the same exception.  Is there something else I can check before using ScrollIntoView?

Below is the top of the stack trace for the exception:

Hi,

If i create a wpf project using the following xaml definition, i'm able to move the "Soccer" treeviewitem before the "futsal" element. When I start draging my element, i can see the option that allow me to insert the item before the previous element.

        <telerik:RadTreeView x:Name="radTreeView" Grid.Row="2" IsDragDropEnabled="True"
                             IsDropPreviewLineEnabled="True">
            <telerik:RadTreeViewItem Header="Sport Categories">
                <telerik:RadTreeViewItem Header="Football">
                    <telerik:RadTreeViewItem Header="Futsal" />
                    <telerik:RadTreeViewItem Header="Soccer" />
                </telerik:RadTreeViewItem>
            </telerik:RadTreeViewItem>
        </telerik:RadTreeView>

If I take the previous control, and I add it in a word 2010 add-in,the option is not available. It doesn't matter where i put my mouse, the "before" or "option" command never show up. I can only insert item inside other item.

Any Ideas why i'm having this behavior? I will try to attach a sample project showing this behavior.

Best Regards,

P.S. It's seem there an issue ID associate with this problem: 1299 - TreeView: Built-in drag and drop does not work in ElementHost. Have you any workaround to suggest me to solve this behavior? 

I can't seem to get the hour interval to work the way I expect it to.

If I use either this:

<Rad:RadTimeBar.Intervals>
	<Rad:MonthInterval />
	<Rad:DayInterval />
	<Rad:HourInterval />
</Rad:RadTimeBar.Intervals>

or this:

<Rad:RadTimeBar.Intervals>
	<Rad:MonthInterval />
	<Rad:DayInterval />
	<Rad:HourInterval  IntervalSpans="1" />
</Rad:RadTimeBar.Intervals>

I am unable to zoom into the 'hourly mode' (see first screenshot).  However 

<Rad:RadTimeBar.Intervals>
	<Rad:MonthInterval />
	<Rad:DayInterval />
	<Rad:HourInterval  IntervalSpans="1,8" />
</Rad:RadTimeBar.Intervals>


allows me to get into the hourly mode but shows the 8 hour interval (which I don't really want). Am I doing something wrong?


The rest of the xaml ( mPlotsGrid is populated with RadLinearSparklines at runtime):
                  <Rad:RadTimeBar Name="mTimeBar"
                                  PeriodStart="{Binding Path=BeginHistory, Mode=TwoWay}"
                                  PeriodEnd="{Binding Path=EndHistory, Mode=TwoWay}"
                                  VisiblePeriodStart="{Binding Path=BeginView, Mode=TwoWay}"
                                  VisiblePeriodEnd="{Binding Path=EndView, Mode=TwoWay}"
                                  SelectionStart="{Binding Path=BeginDetail, Mode=TwoWay}"
                                  SelectionEnd="{Binding Path=EndDetail, Mode=TwoWay}"
                                  IsSnapToIntervalEnabled="True"
                                  MinSelectionRange="00:01:00"
                                  Margin="5">
                     <Rad:RadTimeBar.Intervals>
                        <Rad:MonthInterval />
                        <Rad:WeekInterval />
                        <Rad:DayInterval />
                        <Rad:HourInterval  IntervalSpans="1,8" />
                     </Rad:RadTimeBar.Intervals>
                     <Grid x:Name="mPlotsGrid" />
                  </Rad:RadTimeBar>

I have just downloaded the trial to asses the suitability of the control for an upcoming project.

I am trying to get the load on demand working.
When I try to follow the example the event is fired but on the screen a spinny arrow icon just goes round and round.

Could you please advise.

xaml:

<telerik:RadTreeView Height="250" HorizontalAlignment="Left" Margin="18,24,0,0" Name="radTreeView1" VerticalAlignment="Top" Width="150" IsLoadOnDemandEnabled="True" LoadOnDemand="OnLoadOnDemand"/>

cs:
private void OnLoadOnDemand(object sender, Telerik.Windows.RadRoutedEventArgs e)

{

 

RadTreeViewItem item = e.OriginalSource as RadTreeViewItem;

 

// Adding child items

 

RadTreeViewItem product = new RadTreeViewItem();

product.Header =

 

"Product1.1";

item.Items.Add(product);

product =

 

new RadTreeViewItem();

product.Header =

 

"Product1.1";

item.Items.Add(product);

}
