[Solved] BarSeries width differes when combining Clustered and Stacked combine modes

In the first attached screenshot, I have 6 BarSeries (all with the same values for the data). 5 series are stacked in 2 groups (using the stack key). The sixth series has a combine mode of Clustered. You can see where the Clustered series is much wider than the stacked series. In the second screenshot, I have 3 BarSeries. 2 are Clustered and 1 is Stacked. In this case, the Stacked BarSeries is the one that is wider than the other series. I am using a point template for BarSeries, but it is not doing anything with the width (It's a Border). Is the width difference purposeful, or is this a bug?

Set Design-time theme

Hi,
is it somehow possible to declare the telerik theme so that the controls would have their theme set in designer also?

I'm already setting theme code behind in Application_Startup like

StyleManager.ApplicationTheme = new Expression_DarkTheme();

But I would like to set the theme application wide so that I could see the rad controls wiht the dark theme also in design mode.

Best regards,
Niklas

Custom Resources using IResource

I am trying to use IResource to create custom resources but can not make it work no appointments are displayed, all the resources are displayed in the group headers but no appointments, I have created a class that inherits from IResource and i am setting all the properties (resource name, resource type and display name), I am loading appointments from xaml just like the demo examples and there are i am using my custom class as resource.
I even added group and appointment filter to see what is wrong but they are never even called.

If i use simple Resource class then every thing works

Thanks

Cannot find Datacontext (Viewdefinitions)

I am having problem in binding to the Datacontext at viewdefinition level, It works if i create my viewmodel in xaml and set the DataContext of the grid using staticresource, but if i set the datacontext to the window in code behind it does not work

<schedule:RadScheduleView.ViewDefinitions>
<schedule:DayViewDefinition GroupFilter="{Binding GroupFilter2}"/>
<schedule:WeekViewDefinition GroupFilter="{Binding GroupFilter2}"/>
<schedule:MonthViewDefinition GroupFilter="{Binding GroupFilter2}"/>
</schedule:RadScheduleView.ViewDefinitions>

----------- this does not work, does no bind to Group Filter -----------------
public MainWindow()
{
InitializeComponent();
this.DataContext = new ViewModel();
}

----------- this works -------------------

<Window.Resources>
<local:ViewModel x:Key="ViewModel" AppointmentsSource="/Schedule;component/Appointments.xaml" />
<Grid x:Name="mainGrid" DataContext="{StaticResource ViewModel">

Filtering Highlight Matched Text

I think it would be cool to have the filtered choices in my combobox to have the matching text highlighted.

For example:
[at ]
Documentation
Ultimate
Administrator
Cat in the Hat

Any suggestions on how to go about this?

SelectColumn in Group Header

Hi,

Is it possible to put the selectcolumn or check box into the Group Header?

When the check box in the group header is selected, I will like all the select columns(checkboxes) ticked of the items within the groups.

and when any item in the group is unchecked, I would like the check box in group header is unchecked as well.

When the group has subgroups, I also want the subgroup checkbox to be checked when I loop through them using group.subgroups.

In the case, how could I grad a reference to the checkbox in the subgroup row?

Am I using the right approch with the code below?

<telerik:RadGridView.GroupHeaderTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal">

<CheckBox Click="RadGridViewGroupRowClicked" Margin="0 0 3 0"/>

<TextBlock Text="{Binding Group.Key}" />

</StackPanel>

</DataTemplate>

</telerik:RadGridView.GroupHeaderTemplate>

private void RadGridViewGroupRowClicked(object sender, System.Windows.RoutedEventArgs e)

{

var groupViewModel = (sender as CheckBox).DataContext as GroupViewModel;

var isChecked = (bool) (sender as CheckBox).IsChecked;

CheckUncheckRows(isChecked, groupViewModel);

}

public void CheckUncheckRows(bool isChecked, GroupViewModel groupViewModel)

{

CheckUncheckItems(isChecked, groupViewModel.Group);

}

public void CheckUncheckItems(bool isChecked, IGroup group)

{

if (group.HasSubgroups)

{

foreach (var subgroup in group.Subgroups)

{

CheckUncheckItems(isChecked, subgroup);

}

else

{

foreach (var item in group.Items)

{

if (isChecked)

{

baseToTargetGridView.SelectedItems.Add(item);

}

else

{

baseToTargetGridView.SelectedItems.Remove(item);

}

Thanks,

Yu

Grouping by Object and custom group header

Hi, I'm grouping my list of values from an object.
This object might be one of these 3 classes: Class1, Calss2, Calss3. This is working.

I followed your sample: http://www.telerik.com/forums/group-header-style for a custom header template.

But when I'm selecting the template from each group header I find the string "Class1", "Calss2", "Calss3" instead of its real value.

What am I doing wrong? Am I missing something?
