Tooltip Settings for Tasks

This topic demonstrates the various tooltip customization options available for tasks displayed in the WinGanttView™ control. Tooltips are displayed for tasks that are visible in the chart area of the control. The tooltip settings exist within the TimelineSettings object of the control. For more information on adding tasks to GanttView please see the Adding Tasks to WinGanttView topic.

The following code assumes that you have an UltraGanttView control dropped onto the form that displays parent and child tasks.

In Visual Basic:

' Tooltip settings for child Tasks
Me.ultraGanttView1.TimelineSettings.ToolTipSettings.Appearance.BackColor = Color.BlanchedAlmond
Me.ultraGanttView1.TimelineSettings.ToolTipSettings.DisplayCompleteThrough = DefaultableBoolean.[True]
Me.ultraGanttView1.TimelineSettings.ToolTipSettings.DisplayStartDateTime = DefaultableBoolean.[False]
'Tooltip settings for Milestone
Me.ultraGanttView1.TimelineSettings.ToolTipSettingsMilestone.Appearance.BackColor = Color.LightBlue
Me.ultraGanttView1.TimelineSettings.ToolTipSettingsMilestone.DisplayEndDateTime = DefaultableBoolean.[True]
' Tooltip settings for Percent Complete
Me.ultraGanttView1.TimelineSettings.ToolTipSettingsPercentComplete.DisplayDuration = DefaultableBoolean.[True]
' Tooltip settings for Deadline
Me.ultraGanttView1.TimelineSettings.ToolTipSettingsDeadline.DisplayCompleteThrough = DefaultableBoolean.[True]
' Tooltip settings for Summary Tasks
Me.ultraGanttView1.TimelineSettings.ToolTipSettingsSummary.DisplayDuration = DefaultableBoolean.[False]

In C#:

// Tooltip settings for child Tasks
this.ultraGanttView1.TimelineSettings.ToolTipSettings.Appearance.BackColor = Color.BlanchedAlmond;
this.ultraGanttView1.TimelineSettings.ToolTipSettings.DisplayCompleteThrough = DefaultableBoolean.True;
this.ultraGanttView1.TimelineSettings.ToolTipSettings.DisplayStartDateTime = DefaultableBoolean.False;
//Tooltip settings for Milestone
this.ultraGanttView1.TimelineSettings.ToolTipSettingsMilestone.Appearance.BackColor = Color.LightBlue;
this.ultraGanttView1.TimelineSettings.ToolTipSettingsMilestone.DisplayEndDateTime = DefaultableBoolean.True;
// Tooltip settings for Percent Complete
this.ultraGanttView1.TimelineSettings.ToolTipSettingsPercentComplete.DisplayDuration = DefaultableBoolean.True;
// Tooltip settings for Deadline
this.ultraGanttView1.TimelineSettings.ToolTipSettingsDeadline.DisplayCompleteThrough = DefaultableBoolean.True;
// Tooltip settings for Summary Tasks
this.ultraGanttView1.TimelineSettings.ToolTipSettingsSummary.DisplayDuration = DefaultableBoolean.False;

The TaskToolTipDisplaying event can be fired to add tooltips to Tasks.

In Visual Basic:

this.ultraGanttView1.TaskToolTipDisplaying += new TaskToolTipDisplayingHandler(ultraGanttView1_TaskToolTipDisplaying);
Private Sub ultraGanttView1_TaskToolTipDisplaying(ByVal sender As Object,   ByVal e As Infragistics.Win.UltraWinGanttView.TaskToolTipDisplayingEventArgs) Handles ultraGanttView1.TaskToolTipDisplaying
        Dim info As ToolTipInfo = e.ToolTipInfo
        info.DisplayStyle = ToolTipDisplayStyle.BalloonTip
        info.ToolTipText = e.Task.Resources.ToString()
        e.ToolTipInfo = info
    End Sub

In C#:

this.ultraGanttView1.TaskToolTipDisplaying += new TaskToolTipDisplayingHandler(ultraGanttView1_TaskToolTipDisplaying);
void ultraGanttView1_TaskToolTipDisplaying(object sender, Infragistics.Win.UltraWinGanttView.TaskToolTipDisplayingEventArgs e)
        {
            ToolTipInfo info = e.ToolTipInfo;
            info.DisplayStyle = ToolTipDisplayStyle.BalloonTip;
            info.ToolTipText = e.Task.Resources.ToString();
            e.ToolTipInfo = info;
        }
