Replacing Existing Controls

In a previous section we created a custom user control. As was stated there, you can create only a single new user
control, but you can replace existing controls, namely edit control and the fields control. In our example we will
replace the edit control. The appropriate service is called

UserEditData

service.

Let us replace the current edit control and use a new one for the text fields. First of all we create a new user control
and name it

Edit

.

Place an edit text box on this control. Change the color so that you can easily recognize any effects on Validation:

To be able to work with the control, it must be attached to the respective objects., e.g. to a special field type. In our
example we will attach it only to text fields. To do this, a project must be loaded in Validation. Therefore we place
the code as a function call into

dsValApp_OnProjectLoaded

:

In the function

applyEditControl

we have now to implement the necessary code. We first check if a

Validation project is already available. If this is the case we connect to the Validation field type

TextField

.

It is possible to connect to edit control elements of the

DocumentDesciptor

and elements of the

FieldDescriptor

.

TextField

is an element of the

FieldDescriptor

. For more details you should read the

chapter “Integration”.
