Use a Multiline Editor for String Properties

• Nov 17, 2020

This lesson explains how to display a multiline editor for string properties.

In this lesson, you will enable a multiline text box for the Task.Subject property editor.

Step-by-Step Instructions

1. In the MySolution.Module project, open the Model.DesignedDiffs.xafml file in the Model Editor.
2. Navigate to the BOModel | DevExpress.Persistent.BaseImpl | Task | OwnMembers node.

3. For the Subject child node, set the properties as follows:

   • Set the RowCount property to 2.

     This creates a two-line editor for the Subject property.

   • Set the Size property to 200.

     This allows a user to enter up to 200 symbols. You can also apply the Size attribute in code.

     

• Run the application. Open a detail form for a DemoTask object. The Subject property uses a two-line memo editor.
