Nested Property Value (Long Namespace Name)

[Sayyed Hossein]

hi

assume i have a property named MyProperty of type MyType with namespace address of :
NameSpaceMain.Namespace2.Namespace3. ... .LastNameSpace.MyType


as you know when using nested properties the value of the main property (who owns the nested properties) is shown somehow like this in tyhe propertygrid:


+ MyProperty                      NameSpaceMain.Namespace2.Namespace3. ... LastNameSpace.MyType
    nestedproperty1                  true
    nestedproperty2                  false
    nestedproperty3                  true
    nestedproperty4                  false

what should i do to just show the last part (MyType) or even some other manual Name as the value of my property in the peopertygrid
thank you in advance for your answer

Hi,

 In order to achieve your goal you can override the ToString method of your "MyProperty" class like so:

public override string ToString()
        {
            return String.Format( this.Namespace1.Namespace2.LastNamespace);
        }

Please find attached sample project that meets your requirements.

All the best,

Hey there,

 Regarding your answer: how can I make it so that the Header updates if the ToString method content changes?

 Thanks,

Andrei

Hello Andrei,

Basically, in such scenario the parent object needs to listen for a property change in its nested object. I have modified the sample project in a way that demonstrates how this can be achieved.

I hope this helps.

Hi Stefan,

Sorry for posting on an old thread. But I'm wondering is there a way to achieve this (just need display constant text) without overriding ToString() method?

Hello Rick,

It is possible to bind a given PropertyDefinition to a particular property of an object. With such approach, however, the Nested properties will try to resolve their Binding within this particular property. You can take a look at the code snippet below, as an example.

<telerik:PropertyDefinition DisplayName="Department"
                            Description="Department"
                            Binding="{Binding Department.Country}">
    <telerik:PropertyDefinition.NestedProperties>
        <telerik:PropertyDefinition DisplayName="Country"
                                    Binding="{Binding Country}"/>
        <telerik:PropertyDefinition DisplayName="ID"
                                    Binding="{Binding ID}"/>
    </telerik:PropertyDefinition.NestedProperties>
</telerik:PropertyDefinition>

With this setup, the PropertyDefinition's Binding will search for the Country and ID properties within the Country property. So, I suggest you sticking to the approach of overriding the ToString() method.
