Namespace: DevExpress.XtraRichEdit.API.Native

Assembly: DevExpress.RichEdit.v24.2.Core.dll

NuGet Package: DevExpress.RichEdit.Core

Declaration

C#

TextBoxSizeRule HeightRule { get; set; }

VB.NET

Property HeightRule As TextBoxSizeRule

Property Value

Type	Description
TextBoxSizeRule	An enumeration member that specifies how to determine the text box height.

Available values:

Name	Description
Auto	Sets the height to fit entire text.
Exact	Sets the height to an exact value specified by the Size property.

Remarks

The default value of the HeightRule property is TextBoxSizeRule.Auto and the text box is stretched horizontally to fit its content if necessary. If you set the HeightRule property to TextBoxSizeRule.Exact, the text box retains its size as specified by the Size property.

Note

When a text box is resized by an end user, the HeightRule property is set to TextBoxSizeRule.Exact.
