How to implement comboBox in Model-View-Presenter and handle the MVP when combox text is changed?

[E-John]

Dear All,

How to implement comboBox in Model-View-Presenter?



If Model-View-Presenter is applied to this case, how to implement the comboBox in Model-View-Presenter?

The item in Device Model may support or may not support Password setting, how to disable the password field on Window when the password setting is not supported for the device models, for example, device.Kind = "X3" and device.Kind = "X5" do not support password setting, when combox text is changed to these two items, the "checkBoxPassword" and maskTextBosPassword should be invisible to user.

Thanks and Best regards,

E-John
