Overview

By default, automatic project calculations in the xamGantt control occur with every edit.

This behavior is configurable, and you may explicitly calculate the project as needed.

Property settings

The following table maps the explicit project’s calculation configuration to property settings.

In order to:	Use:	And set it to:
Disables automatic project calculation	ShouldCalculateAfterEachEdit	`False`
Explicitly calculate the project	Project Calculate method	-

Example

The example below demonstrates how you explicitly calculate a project; triggered by clicking the ‘Calculate’ Button:

In XAML:

<ig:ListBackedProject x:Name="dataProvider"
                      TaskItemsSource="{Binding Tasks}"
<!-- Add ProjectTask Property Mappings Here -->
    <ig:ListBackedProject.Settings>
        <ig:ProjectSettings ShouldCalculateAfterEachEdit=" />
    </ig:ListBackedProject.Settings>
</ig:ListBackedProject>
<ig:XamGantt x:Name="gantt"
             Project="{Binding ElementName=dataProvider}"/>
…
<Button x:Name="Btn_Calculate" Content="Calculate"
        Click="Btn_Calculate_Click" />

In C#:

private void Btn_Calculate_Click(object sender, RoutedEventArgs e)
{
    this.dataProvider.Calculate();
}

In Visual Basic:

Private Sub Btn_Calculate_Click(sender As Object, e As RoutedEventArgs)
    Me.dataProvider.Calculate()
End Sub
