BusyIndicator over ListBox has style issue

When a ListBox is "below" a RadBusyIndicator in the visual tree, it seems to have a focus
or styling issue; its color changes to a light gray or off-white. Is this a known issue or
expected behavior? Is there a work-around? Here is a sample UserControl I threw together
to demonstrate what it's doing. The first ListBox appears correctly, the second one is shaded.

<UserControl x:Class="ListBoxFocusIssueUC"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:tk="http://schemas.telerik.com/2008/xaml/presentation"
             mc:Ignorable="d"
             d:DesignHeight="300" d:DesignWidth="300">

  <tk:RadBusyIndicator Grid.Row="1" Background="Transparent" BusyContent="Testing..." IsBusy="true">
   <ListBox BorderThickness="0" MaxHeight="80">
    <ListBox.Items>
     <ListBoxItem Content="Item #1" />
     <ListBoxItem Content="Item #2" />
     <ListBoxItem Content="Item #3" />
    </ListBox.Items>
   </ListBox>
  </tk:RadBusyIndicator>
</Grid>
</UserControl>

GridViewComboBoxColum with IsComboBoxEditable="true" never sets value

I have the following column in a grid:

<t:GridViewComboBoxColumn IsComboBoxEditable="True"

DataMemberBinding="{Binding Path=QuoteNum, Mode=TwoWay}"

Header="Quote" Width="125"

ItemsSource="{Binding Path=AvailableQuotes, Mode=OneWay}" />



The ItemsSource is a simple IEnumerable<string>, and the combo shows the values from the ItemsSource, but I also want to allow the user to input a value that is not in the list (ItemsSource), hence the IsComboBoxEditable="True".



However, whenever you type in a value to the combobox, the value is lost and the column is left unset.  In fact, as far as I can tell the property setter on the view model is never actually called.



What am I doing wrong?

Frozen / Pinned Rows

Hello,

I am looking to add frozen / pinned row functionality to our grids, just like Excel. I've already found this blog post and modified it for WPF.

http://blogs.telerik.com/blogs/posts/10-07-05/frozen-pinned-rows-in-radgridview-for-silverlight.aspx

There are still a few items which I am struggling with. The first, which is quite major, is that the sample simply uses auto generated columns. That will not work for me, I need to specify the columns. Our columns are defined in XAML and can be quite complex, with DataTemplates and a number of styling options configured. I don't want to define those again somewhere, and even if I do I'm not sure how I would access them. I simply want the columns that are already in the grid to appear in the frozen container as well.

The second item, is that the Column Headers are not appearing, not sure why.

RowDetailsTemplate causing an infinite loop

Hi,

in my wpf usercontrol, I have a RadGridView with a RowDetailsTemplate inside of it. The template contain a RadTabControl and a only one TabItem with nothning inside of or if you want, we can add a TextBlock inside of it, it doesn't matter.

When I see my grid, I have my column with the "+" sign, when I click on the sign, my app hang and after 1 or 2 minutes, my Visual Studio tell me that I fall in an infinite loop.

Juste the fact to remove the RadTabItem it solve the problem!!!

Here is the xaml of my control:

            <telerik:RadGridView.Columns>
                <telerik:GridViewToggleRowDetailsColumn />

                <telerik:RadGridView.RowStyle>
                    <Style TargetType="telerik:GridViewRow">
                        <Setter Property="MinHeight" Value="40"/>
                    </Style>
                </telerik:RadGridView.RowStyle>

<telerik:RadGridView.RowDetailsTemplate>
                    <DataTemplate>

Create Appointment - Frequency Weekly by Code?

Hi,

I'm not able to create an appointment with a frequency like weekly by c# Code! No error but the appointment is not shown in
the scheduleview! Why?

I'm using WPF RadControls 2012 Q1 SP1 and c# .Net 4.0

foreach (DataRow tasks_dr in passw_dt.Rows)

{

DateTime start = Convert.ToDateTime(tasks_dr.Field<String>("StartDatum"));

switch (start.DayOfWeek)

{

case DayOfWeek.Saturday:

start = start.AddDays(2);

break;

case DayOfWeek.Sunday:

start = start.AddDays(1);

break;

}

TimeSpan duration = TimeSpan.FromDays(5);

DateTime end = Convert.ToDateTime(tasks_dr.Field<String>("Enddatum"));

switch (end.DayOfWeek)

{

case DayOfWeek.Sunday:

end = end.AddDays(-1);

break;

case DayOfWeek.Monday:

end = end.AddDays(-2);

break;

}

Appointment appointment = new Appointment

{

Start = start,

Url = Convert.ToString(tasks_dr.Field<Int64>("id") + "#" + tasks_dr.Field<String>("Betreuer")),

End = end,

Subject = tasks_dr.Field<String>("Subject"),

Body = tasks_dr.Field<String>("Body"),

Importance = GetImportance(tasks_dr.Field<String>("Importance"))

};

if (tasks_dr.Field<String>("Kategorie") == "Fertig")

{

appointment.Category = this.Categories[0];

}

else if (tasks_dr.Field<String>("Kategorie") == "in Arbeit")

{

appointment.Category = this.Categories[1];

}

else

{

appointment.Category = this.Categories[2];

}

if (tasks_dr.Field<Int64>("Ganztag") == 0)

{

appointment.IsAllDayEvent = false;

}

else

{

appointment.IsAllDayEvent = true;

}

var Pattern = new RecurrencePattern();

Pattern.Frequency = GetFreuqency(tasks_dr.Field<String>("Frequency"));

if (Pattern.Frequency != RecurrenceFrequency.None)

{

Pattern.DayOrdinal = Convert.ToInt32(tasks_dr.Field<Int64>("DayOridnal"));

Pattern.DaysOfWeekMask = GetDay(tasks_dr.Field<String>("DaysofWeekMask"));

Pattern.FirstDayOfWeek = GetFirstday(tasks_dr.Field<Int64>("FirstDayOfWeek"));

Pattern.Interval = Convert.ToInt32(tasks_dr.Field<Int64>("Interval"));

Pattern.MaxOccurrences = Convert.ToInt32(tasks_dr.Field<Int64>("MaxOccurrences"));

Pattern.MonthOfYear = Convert.ToInt32(tasks_dr.Field<Int64>("MonthofYear"));

Pattern.DayOfMonth = Convert.ToInt32(tasks_dr.Field<Int64>("DayofMonth"));

System.DateTime? RecursUntil_d;

if (tasks_dr.Field<String>("RecursUntil") != "")

{

RecursUntil_d = Convert.ToDateTime(tasks_dr.Field<String>("RecursUntil"));

}

Pattern.RecursUntil = RecursUntil_d;

appointment.RecurrenceRule = new RecurrenceRule(Pattern);

}

this.appointments.Add(appointment);

Every appointment withput a freqeuncy is shown fine. Thanks

Tab navigation on gridview with custom column

Hi,

I have a gridview that consists of mix data bound columns and custom template column. The custom template column are basically a check box column and a calendar column. I used the techniques from this example to create those custom column (using the CreateCellElement)

http://www.telerik.com/community/forums/wpf/gridview/tab-navigation-in-a-grid-with-a-button-column.aspx

The check box column works fine with tabbing to/from the column. However the issue is with the Calendar column, as the tabbing doesn’t get the focus in the calendar control inside the column, and it doesn’t move away from it to move to the next column. Instead the focus moves to the next control beside the grid.

Any advice how to accomplish a smooth tab navigation between all column, and have the focus land in the inner controls when it is a custom column?

Regards

public override FrameworkElement CreateCellEditElement(GridViewCell cell, object dataItem)

{

cell.GotFocus += this.cell_GotFocus;

var picker = cell.Content as RmpDatePicker ?? new RmpDatePicker()

{

HorizontalAlignment = HorizontalAlignment.Stretch

};

this.BindingTarget = RmpDatePicker.SelectedDateProperty;

picker.SetBinding(this.BindingTarget, this.CreateValueBinding());

return picker;

}

private void cell_GotFocus(object sender, RoutedEventArgs e)
