Code Example: Inserting and Deleting Tasks in xamGantt Using Commands

Description

The following code explains how to use xamGantt commands to insert and delete tasks.

Code

Add the following namespaces in your page:

In XAML:

xmlns:ig="http://schemas.infragistics.com/xaml"
xmlns:igPrim="http://schemas.infragistics.com/xaml/primitives"

The code below adds a xamGantt and two buttons to your page to perform inserting and deleting tasks using commands.

In XAML:

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="22" />
    </Grid.RowDefinitions>
    <ig:XamGantt x:Name="gantt" Project="{Binding}" />
        <StackPanel Grid.Row="1" Orientation="Horizontal">
            <Button x:Name="Btn_InsertTask" Content="Insert Task">
                <ig:Commanding.Command>
                    <igPrim:GanttCommandSource
                        TargetName="gantt"
                        CommandType="InsertTask"
                        EventName="Click"/>
                </ig:Commanding.Command>
            </Button>
            <Button x:Name="Btn_DeleteTask" Content="Delete Task">
                <ig:Commanding.Command>
                    <igPrim:GanttCommandSource
                        TargetName="gantt"
                        CommandType="DeleteTask"
                        EventName="Click"/>
                </ig:Commanding.Command>
