1. To bind the Scheduler to Resources collection, you need to set its ResourcesSource property to point to the collection.

C#

List rentalUnits = new List();
string[] names = new string[] { “All Rooms”, “1 bedroom condo #1″, “1 bedroom condo #2″, “2 bedroom condo #1″, “2 bedroom condo #2″, “2 bedroom condo #3″, “3 bedroom condo #1″, “3 bedroom Villa #1″, “3 bedroom Villa #2″, “4 bedroom Villa #1″ };

for (int i = 0; i < names.Length; i++)
{
Room room = new Room() { Name = names[i] };
rentalUnits.Add(room);
}

this.Scheduler.ResourcesSource = rentalUnits;

VB .NET

Dim rentalUnits As List(Of Room) = New List(Of Room)()
Dim names() As String = { "All Rooms", "1 bedroom condo #1", "1 bedroom condo #2", "2 bedroom condo #1", "2 bedroom condo #2", "2 bedroom condo #3", "3 bedroom condo #1", "3 bedroom Villa #1", "3 bedroom Villa #2", "4 bedroom Villa #1" }

For i As Integer = 0 To names.Length – 1
Dim room As New Room() With {.Name = names(i)}
rentalUnits.Add(room)
Next i
Me.Scheduler.ResourcesSource = rentalUnits

2. The following example code represents the Room object that we used as Resource.
C#

public class Room
{
public Room()
{
}

public string Name
{
get;
set;
}
}

VB .NET

Public Class Room
Public Sub New()
End Sub

Private privateName As String
Public Property Name() As String
Get
Return privateName
End Get
Set(ByVal value As String)
privateName = value
End Set
End Property
End Class

3. If you want to make some additional modifications to the resource before it appear in the Scheduler, you can subscribe to the ResourceCreated event.

C#

this.Scheduler.ResourceCreated += new EventHandler(Scheduler_ResourceCreated);

VB .NET

AddHandler Scheduler.ResourceCreated, AddressOf Scheduler_ResourceCreated

4. In the event handler, you can customize the Resource’s appearance by setting its Style or DataTemplate properties. The Style property allows you to change the resource’s Background, Border and BorderThickness. Setting the DataTemplate property will change the entire look of the Resource.

C#

Color[] resourceColors = new Color[] { Color.FromArgb(255, 199, 203, 209), Color.FromArgb(255, 165, 191, 225), Color.FromArgb(255, 177, 205, 164), Color.FromArgb(255, 219, 172, 188),
Color.FromArgb(255, 191, 175, 225), Color.FromArgb(255, 207, 193, 165), Color.FromArgb(255, 172, 188, 219), Color.FromArgb(255, 168, 197, 212), Color.FromArgb(255, 221, 172, 172),
Color.FromArgb(255, 255, 230, 159)};
int resourceIndex;

void Scheduler_ResourceCreated(object sender, ResourceEventArgs e)
{
if (resourceIndex >= resourceColors.Length)
{
resourceIndex = 0;
}

// Set resource’s style.
StylePart style = new StylePart() { Background = new SolidColorBrush(resourceColors[resourceIndex]), BorderBrush = new SolidColorBrush(resourceColors[resourceIndex]), BorderThickness = new Thickness(1) };
e.Resource.Style = style;
resourceIndex++;
}

VB .NET

Private resourceColors() As Color = { Color.FromArgb(255, 199, 203, 209), Color.FromArgb(255, 165, 191, 225), Color.FromArgb(255, 177, 205, 164), Color.FromArgb(255, 219, 172, 188), Color.FromArgb(255, 191, 175, 225), Color.FromArgb(255, 207, 193, 165), Color.FromArgb(255, 172, 188, 219), Color.FromArgb(255, 168, 197, 212), Color.FromArgb(255, 221, 172, 172), Color.FromArgb(255, 255, 230, 159)}
Private resourceIndex As Integer

Private Sub Scheduler_ResourceCreated(ByVal sender As Object, ByVal e As ResourceEventArgs)
If resourceIndex >= resourceColors.Length Then
resourceIndex = 0
End If

‘ Set resource’s style.
Dim style As New StylePart() With {.Background = New SolidColorBrush(resourceColors(resourceIndex)), .BorderBrush = New SolidColorBrush(resourceColors(resourceIndex)), .BorderThickness = New Thickness(1)}
e.Resource.Style = style
resourceIndex += 1
End Sub

1. Set the GroupingDefaultHeaderTextVisible to false and subscribe to the GroupHeaderCustomTextNeeded event of VIBlend DataGridView.

2. Calculate the summary values in the event handler and set the args.HeaderText, args.HeaderTextAlignment, args.HeaderFont and args.HeaderTextColor properties to specify the group’s text, text alignment, text color and font.

C#

void Grid1_GroupHeaderCustomTextNeeded(object sender, vDataGridView.GroupHeaderCustomTextNeededEventArgs args)
{
args.HeaderTextColor = Color.Black;
args.HeaderTextAlignment = ContentAlignment.MiddleLeft;
args.HeaderFont = this.Grid1.Font;

if (args.Row.Depth == 0)
{
List<EmployeeSales> employeeProducts = new List<EmployeeSales>();
foreach (EmployeeSales employee in this.lst)
{
if (employee.Name.Equals(args.Row.Caption))
{
employeeProducts.Add(employee);
}
}

double sum = 0;
foreach (EmployeeSales employee in employeeProducts)
{
sum += employee.SalesAmount;
}
args.HeaderText = “Employee: ” + args.Row.Caption + ” Total: $” + sum;
}
else
{
List<EmployeeSales> employeeProducts = new List<EmployeeSales>();
foreach (EmployeeSales employee in this.lst)
{
if (employee.ProductName.Equals(args.Row.Caption) && employee.Name.Equals(args.Row.ParentItem.Caption))
{
employeeProducts.Add(employee);
}
}

double sum = 0;
foreach (EmployeeSales employee in employeeProducts)
{
sum += employee.SalesAmount;
}
args.HeaderText = “Product: ” + args.Row.Caption + ” Total: $” + sum;
}
}

VB .NET

Private Sub Grid1_GroupHeaderCustomTextNeeded(ByVal sender As Object, ByVal args As vDataGridView.GroupHeaderCustomTextNeededEventArgs)
args.HeaderTextColor = Color.Black
args.HeaderTextAlignment = ContentAlignment.MiddleLeft
args.HeaderFont = Me.Grid1.Font

If args.Row.Depth = 0 Then
Dim employeeProducts As List(Of EmployeeSales) = New List(Of EmployeeSales)()
For Each employee As EmployeeSales In Me.lst
If employee.Name.Equals(args.Row.Caption) Then
employeeProducts.Add(employee)
End If
Next employee

Dim sum As Double = 0
For Each employee As EmployeeSales In employeeProducts
sum += employee.SalesAmount
Next employee
args.HeaderText = “Employee: ” & args.Row.Caption & ” Total: $” & sum
Else
Dim employeeProducts As List(Of EmployeeSales) = New List(Of EmployeeSales)()
For Each employee As EmployeeSales In Me.lst
If employee.ProductName.Equals(args.Row.Caption) AndAlso employee.Name.Equals(args.Row.ParentItem.Caption) Then
employeeProducts.Add(employee)
End If
Next employee

Dim sum As Double = 0
For Each employee As EmployeeSales In employeeProducts
sum += employee.SalesAmount
Next employee
args.HeaderText = “Product: ” & args.Row.Caption & ” Total: $” & sum
End If
End Sub

The code snippet below shows how to create a repeating appointment and add it to the vMonthCalendar control.

C#

vAppointment appointment = new vAppointment();
appointment.Date = DateTime.Now.Date.AddDays(2);
appointment.RecurrenceRule = RecurrenceRule.Daily;
appointment.RecurrenceRange.NumberOfOccurences = 5;
this.vMonthCalendar1.Appointments.Add(appointment);
this.vMonthCalendar1.CurrentDate = DateTime.Now.Date;

VB .NET

Dim appointment As New vAppointment()
appointment.Date = DateTime.Now.Date.AddDays(2)
appointment.RecurrenceRule = RecurrenceRule.Daily
appointment.RecurrenceRange.NumberOfOccurences = 5
Me.vMonthCalendar1.Appointments.Add(appointment)
Me.vMonthCalendar1.CurrentDate = DateTime.Now.Date

The appointment’s RecurrenceRule property is set to Daily. Doing this, the appointment will occur every day after its start date. To restrict the number of occurrences, we also set the appointment.RecurrenceRange.NumberOfOccurences property. The Month Calendar appointments support Daily, Weekly, Monthly and Yearly recurrence patterns.

<viblend:DataGrid x:Name=”dataGrid” AutoGenerateColumns=”True” Margin=”4″>
<viblend:DataGrid.BoundFields>
<viblend:BoundField Text=”Name” DataField=”Name” Width=”160″ SortMode=”Automatic”/>
<viblend:BoundField Text=”Date” DataField=”Date” Width=”140″ SortMode=”Automatic”/>
<viblend:BoundField Text=”Product” DataField=”Product” Width=”140″ SortMode=”Automatic”/>
<viblend:BoundField Text=”Quantity” DataField=”Quantity” Width=”90″ SortMode=”Automatic”/>
<viblend:BoundField Text=”Unit Price” DataField=”UnitPrice” Width=”72″ SortMode=”Automatic”/>
<viblend:BoundField Text=”Sales Amount” DataField=”SalesAmount” Width=”80″ SortMode=”Automatic”/>
</viblend:DataGrid.BoundFields>
</viblend:DataGrid>

The HierarchyItem class also has a SortMode property, to you can set it at run-time, too.

For example:

foreach (HierarchyItem item in dataGrid.ColumnsHierarchy.Items)
{
item.SortMode = GridItemSortMode.Automatic;
}

The HierarchyItem.SortMode and BoundField.SortMode properties are supported in VIBlend DataGrid for WinForms, WPF and Silverlight.

The following code aligns the header text and image to the middle-right position:

this.navigationPane.Items[0].HeaderTextAlignment = ContentAlignment.MiddleRight;

this.navigationPane.Items[0].HeaderImageAlignment = ContentAlignment.MiddleRight;

In this blog post, we demonstrate how to create and add repeating appointments to the VIBlend Silverlight Scheduler.

To create a repeating appointment in VIBlend Silverlight Scheduler, you can follow these steps:

• Double-Click on any scheduler cell or right-click to open the built-in context menu and click ‘New Appointment’.
• In the pop-up window that appears, click the Repeat… checkbox.
• Choose your desired settings in the Recurrence Dialog and click ‘Ok’.
• Fill in the appointment’s other details.
• Click Save and Close to confirm the changes.

To make an existing appointment repeat, follow these steps:

• Double-Click on the appointment and in the pop-up window that appears, click the Repeat… checkbox.
• Choose your desired settings in the Recurrence Dialog and click ‘Ok’.
• Fill in the appointment’s other details.
• Click Save and Close to confirm the changes.

To create a repeating appointment in the code-behind, follow these steps:

• Create a new Appointment object. Set the appointment’s start, duration, subject, description and location fields.

C#

DateTime appointmentStart = DateTime.Now.Date;
TimeSpan appointmentDuration = new TimeSpan(1, 0, 0);
Appointment lunchBreak = new Appointment(appointmentStart, appointmentDuration, “Lunch Break”, “Steamed fillet of trout, served with sour-cream sauce, cucumber salad and boiled potatoes”, “Lunch Room 1″);

VB .NET

Dim appointmentStart As DateTime = DateTime.Now.Date
Dim appointmentDuration As New TimeSpan(1, 0, 0)
Dim lunchBreak As New Appointment(appointmentStart, appointmentDuration, “Lunch Break”, “Steamed fillet of trout, served with sour-cream sauce, cucumber salad and boiled potatoes”, “Lunch Room 1″)

• Set the Appointment’s RecurrencePattern property to make it repeat. You can set this property to any class derived from the RecurrencePattern class. VIBlend Scheduler control provides four built-in recurrence patterns represented by the DayRecurrencePattern, MonthRecurrencePattern, YearRecurrencePattern and WeekRecurrencePattern classes. The following code snippet demonstrates how to specify a daily repeating behavior:

C#

lunchBreak.RecurrencePattern = new DayRecurrencePattern(lunchBreak.From, this.viblendScheduler.View.To, 1);

VB .NET

lunchBreak.RecurrencePattern = New DayRecurrencePattern(lunchBreak.From, Me.viblendScheduler.View.To, 1)

In the daily recurrence pattern, you need to specify the RepeatIndex property which determines the days between two occurences. The default property value is 1.

• Finally, add the appointment to the Scheduler.

C#this.viblendScheduler.Appointments.Add(lunchBreak);

VB .NET

Me.viblendScheduler.Appointments.Add(lunchBreak)
