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.Columns>

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

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)

{

var picker = (sender as GridViewCell).ChildrenOfType<RmpDatePicker>().FirstOrDefault();

if (picker == null) return;

picker.Focus();

picker.HorizontalAlignment = HorizontalAlignment.Stretch;

}

private Binding CreateValueBinding()

{

var valueBinding = new Binding

{

Mode = BindingMode.TwoWay,

NotifyOnValidationError = true,

ValidatesOnExceptions = true,

UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged,

Path = new PropertyPath(this.DataMemberBinding.Path.Path)

};

return valueBinding;

}

How to bind different sources to combos in grids

I have a grid in which comboboxes are shown in each row to allow for selection of color for the item in that row.

Now we wish to have different lists of colors depending on the row; i.e. the itemssource for the comboboxes are no longer the same.

Before I had a single color-list on the viewmodel for the grid and xaml-databound-bound the comboboxes to that.

How do I get different itemssources for the comboboxes?

Thanks for any input,

Anders, Denmark
