Hi Salvatore,
We have created a sample to modifying the existing commands. By using the commands property we can able to modify the existing commands in the diagram. When any one of the default commands is not desired, they can be disabled. To change the functionality of a specific command, the command can be completely modified. Please refer to code snippet and sample

<SfDiagramComponent @ref="@diagram" Height="600px" Nodes="@nodes">
@* Initializing the custom commands *@
<CommandManager>
<CommandManager Commands="@commands" Execute="@CommandExecute" CanExecute="@Canexe">
</CommandManager>
</CommandManager>
</SfDiagramComponent>
public void CommandExecute(CommandKeyArgs args)
{
if (args.Gesture.Modifiers == ModifierKeys.None && (args.Gesture.Key == Keys.ArrowUp || args.Gesture.Key == Keys.ArrowDown || args.Gesture.Key == Keys.ArrowRight
|| args.Gesture.Key == Keys.ArrowLeft))
{
//to disable a built-in command and none of action execute
}
if (args.Gesture.Modifiers == ModifierKeys.Control && (args.Gesture.Key == Keys.C || args.Gesture.Key == Keys.X || args.Gesture.Key == Keys.V))
{
//to disable a built-in command and none of action execute
}
} |
