DateTimeFromPoint Method (ControlWithActivityBase)

Returns the DateTime at the specified point, or null if the hit test did not yield a date/time.

Syntax

Visual Basic

'Declaration
 
Public Overridable Function DateTimeFromPoint( _
   ByVal point As Point _
) As Nullable(Of Date)

C#

public virtual Nullable<DateTime> DateTimeFromPoint( 
   Point point
)

Parameters

point

The location to test, expressed in client coordinates.

Example

The following code sample demonstrates how to use the OwnerFromPoint and DateTimeFromPoint methods to hit test for an Owner, date, and TimeSlot in the UltraDayView control:

Visual Basic

Imports System.Collections.Generic
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinSchedule
Imports System.Diagnostics

    AddHandler Me.dayView.MouseDown, AddressOf dayView_MouseDown

    Private Sub dayView_MouseDown(ByVal sender As Object, ByVal e As MouseEventArgs)

        Dim dayView As UltraDayView = sender

        Dim ownerAtPoint = dayView.OwnerFromPoint(e.Location)

        Dim timeSlot As TimeSlot = Nothing
        Dim dateAtPoint As Nullable(Of DateTime) = dayView.DateTimeFromPoint(e.Location, timeSlot)

        If Not ownerAtPoint Is Nothing AndAlso dateAtPoint.HasValue Then

            Dim timeRange As TimeRange = Nothing
            If Not timeSlot Is Nothing Then timeRange = Infragistics.Win.UltraWinSchedule.TimeRange.FromTimeSlot(timeSlot, False)
            Dim timeRangeString As String = String.Empty
            If Not timeRange Is Nothing Then timeRangeString = String.Format(", TimeSlot = {0}", timeRange.ToString(True))

            Console.WriteLine(String.Format("Owner = '{0}', Date = {1}{2}", ownerAtPoint.Key, dateAtPoint.Value.ToShortDateString(), timeRangeString))
        End If
    End Sub

C#

using System.Collections.Generic;
using Infragistics.Win;
using Infragistics.Win.UltraWinSchedule;
using System.Diagnostics;

    this.dayView.MouseDown += new MouseEventHandler(dayView_MouseDown);

    void dayView_MouseDown(object sender, MouseEventArgs e)
    {
        UltraDayView dayView = sender as UltraDayView;

        Owner ownerAtPoint = dayView.OwnerFromPoint( e.Location );

        TimeSlot timeSlot = null;
        Nullable<DateTime> dateAtPoint = dayView.DateTimeFromPoint( e.Location, out timeSlot );

        if ( ownerAtPoint != null && dateAtPoint.HasValue )
        {
            TimeRange timeRange = timeSlot != null ? TimeRange.FromTimeSlot( timeSlot, false ) : null;
            string timeRangeString = timeSlot != null ? string.Format(", TimeSlot = {0}", timeRange.ToString(true)) : string.Empty;
            Console.WriteLine( string.Format( "Owner = '{0}', Date = {1}{2}", ownerAtPoint.Key, dateAtPoint.Value.ToShortDateString(), timeRangeString) );
        }
    }
