Hi,

how can I avoid that a property grid overrides a TextBox's error template. I do not want to see the red triangle and red sliding tooltip there. Could not locate the right place in styles (Office Black).

Thanks.

Greetings,

I am using the RadScheduleView (2014.2.617.45) with the TimeLineViewDefinition. I created a button that allows the user to increase and decrease the MinAppointmentHeight during runtime. This is done through a binding to a double property on the corresponding viewmodel. By clicking the button, the property is increased/decreased by a constant value. The binding uses Mode="Default" so that the appointments will initially be scaled according to the size of the ResourceGroupHeaders.

Our problem is that once the user changes the MinAppointmentHeight for the first time, the ScheduleView seems unable to render correctly. You can see the difference in the attached screenshots. Image 1 shows the scheduler before any changes to the MinAppointmentHeight, while Image 2 shows the invalid rendering. Somehow, this only happens after the first change to MinAppointmentHeight. Every following change will cause the scheduler to render correctly again.

Could you please evaluate if this is indeed a bug? If so, would you be so kind to see if you could find any reasonable workaround until it is fixed?

Kind regards,
Hendrik

I have an collection of Employee objects who have a collection of Assignment objects as a property.  The Assignment object has an Employee object property.

I have another collection of "Unassigned" Assignments.

UI-wise I want to drag and drop from the Unassigned RadListBox to the assignment RadListBox of an Employee.

I have the drag and drop down. What I am missing is updating the Assignment.Employee property after an Assignment is dropped into the Employee.Assignments collection.  I have looked at overriding the DragDropBehavior,  but I do not see a way of accessing the data object that contains the DestinationItemsSource.

Help?

Hi

I get the following error warning when exporting and 'xls' extension:

'The file you are trying to open is in a different format than specified by the file extension.  Verify that the file is not corrupted and id from a trusted source before opening the file.  Do you want to open the file now?'

This happen in the online demo and in my program.  How do I prevent this message from occurring?

I am using Excel 2010 and the latest Telerik libraries

Thanks

Hi,

We're using the office 2013 theme and as a result, the headers of our gridviews show the text in uppercase.  This is expected due to the theme.

However, we'd like to have the header not uppercase this text.  The way we currently have our application using the theme is by including the various xaml files (including Telerik.Windows.Controls.GridView.xaml) as resource files and then we merge these in.

So we tried changing the following:

<ControlTemplate x:Key="CommonColumnHeaderTemplate" TargetType="grid:CommonColumnHeader">
        <Grid x:Name="PART_HeaderCellGrid" Background="Transparent">
            <Border x:Name="GridViewHeaderCell"
                    Background="{TemplateBinding Background}"
                    BorderBrush="{TemplateBinding BorderBrush}"
                    BorderThickness="{TemplateBinding BorderThickness}"
                    Margin="-1 0 1 0"/>
            <ContentControl x:Name="ContentPresenter"
                    Content="{Binding Content,Converter={StaticResource UppercaseConverter},RelativeSource={RelativeSource TemplatedParent}}"
                    ContentTemplate="{TemplateBinding ContentTemplate}"
                    VerticalAlignment="Center"
                    VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"
                    Margin="{TemplateBinding Padding}"
                    HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}"/>
        </Grid>
    </ControlTemplate>

To this:

<ControlTemplate x:Key="CommonColumnHeaderTemplate" TargetType="grid:CommonColumnHeader">
        <Grid x:Name="PART_HeaderCellGrid" Background="Transparent">
            <Border x:Name="GridViewHeaderCell"
                    Background="{TemplateBinding Background}"
                    BorderBrush="{TemplateBinding BorderBrush}"
                    BorderThickness="{TemplateBinding BorderThickness}"
                    Margin="-1 0 1 0"/>
            <ContentControl x:Name="ContentPresenter"
                   
Content="{Binding Content,RelativeSource={RelativeSource TemplatedParent}}"                <----- CHANGE IS HERE
                    ContentTemplate="{TemplateBinding ContentTemplate}"
                    VerticalAlignment="Center"
                    VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"
                    Margin="{TemplateBinding Padding}"
                    HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}"/>
        </Grid>
    </ControlTemplate>

But we think this must not be the right place to make the change.  Could you direct us to what we should change to get the header text showing with regular (not upper) casing?  Thanks!

Hi everyone !
I discovered Telerik few weeks ago and i try to use it since, but i have a problem :

I have one RedCartesianChart with a ChartView. I also have a checkBox which add another ChartView (in the same RedCartesianChart) when checked. How can i assign a tooltipTemplate for each chart ?

I try with something like : TooltipTemplate="{StaticResource MyTooltipTemplate}", but it applies the template for the whole RedCartesianChart and not just for one ChartView

I can add the source if needed.

All tips are welcome !
Thanks

Simple question. I got my RadLegend element besides my RadCartesianChart with 6 series inside of them. (https://dl.dropboxusercontent.com/u/55589036/Pictures/Screenshots/20150112135601.png)

How can I force the RadLegend to display its items in a row instead of a column?

How can i change the border color of combobox when it has keyboard focus, I am trying to change this in combo box style but it has no effect

<Border x:Name="FocusVisual" BorderBrush="#FFFFC92B" BorderThickness="{TemplateBinding BorderThickness}" Grid.ColumnSpan="2" CornerRadius="1" IsHitTestVisible="False" Visibility="Collapsed">
<Border BorderBrush="Transparent" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="0"/>
</Border>

Also is there any example that shows how to change several other colors, like background of combo box button chrome, color on mouse over, color when drop down is open, mouse over for items
Are there static brushes for any of these or i have create whole new style

I am using implicit styles

thanks

Hi,

I have a contextual menu with submenu and some of them are bound to an items source. I use DropDownHeight to limit the height of a sub menu but since the quantity of item displayed can change, it happens that I have space left at the end of my menu when there isn't a lot of item. Is there a way to set a maximum height to the drop down, that doesn't impose a minimum ?

Thank you,

Etienne
