You can use the CrmDefaultAttribute attribute to specify a default value for in input parameter. The following examples show how to set the default for each type.

Example

The following example shows adding the input and output attributes to a CrmNumber property used in a custom workflow activity with the addition of the CrmDefault attribute.

public static DependencyProperty myNumberProperty = DependencyProperty.Register("myNumber", typeof(CrmNumber), typeof(DefaultValueTestActivity));

[CrmInput("My Integer")]
[CrmOutput("My Integer Output")]
[CrmDefault("2322")]
public CrmNumber myNumber
{
    get
    {
        return (CrmNumber)base.GetValue(myNumberProperty);
    }
    set
    {
        base.SetValue(myNumberProperty, value);
    }
}

Example

The following example shows adding the input and output attributes to a String property used in a custom workflow activity with the addition of the CrmDefault attribute.

public static DependencyProperty myStringProperty = DependencyProperty.Register("myString", typeof(System.String), typeof(DefaultValueTestActivity));

[CrmInput("My String")]
[CrmOutput("My String Output")]
[CrmDefault("My Default String")]
public string myString
{
    get
    {
        return (string)base.GetValue(myStringProperty);
    }
    set
    {
        base.SetValue(myStringProperty, value);
    }
}

Example

The following example shows adding the input and output attributes to a CrmBoolean property used in a custom workflow activity with the addition of the CrmDefault attribute.

public static DependencyProperty myBooleanProperty = DependencyProperty.Register("myBoolean", typeof(CrmBoolean), typeof(DefaultValueTestActivity));

[CrmInput("My Boolean")]
[CrmOutput("My Boolean Output")]
[CrmDefault("True")]
public CrmBoolean myBoolean
{
    get
    {
        return (CrmBoolean)base.GetValue(myBooleanProperty);
    }
    set
    {
        base.SetValue(myBooleanProperty, value);
    }
}

    get
    {
        return (Lookup)base.GetValue(myLookupProperty);
    }
    set
    {
        base.SetValue(myLookupProperty, value);
    }
}
