MemoEdit Class

Allows you to display and edit multi-line text.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v21.2.dll

Declaration

public class MemoEdit :
    TextEdit,
    IAutoHeightControl,
    IAutoHeightControlEx

Remarks

The MemoEdit control represents an editor which allows for the display and editing of multi-line text. It provides a MemoEdit.Lines property defining the list of strings displayed. The image below shows a sample memo editor.

You can use the RepositoryItemMemoEdit.WordWrap property to specify whether long strings, which do not contain any return characters, are wrapped automatically at the right edge of a memo edit control. To determine whether scroll bars should be displayed in a memo editor, use the RepositoryItemMemoEdit.ScrollBars property.

The RepositoryItemMemoEdit.AcceptsReturn and RepositoryItemMemoEdit.AcceptsTab properties define how a memo editor interprets ENTER and TAB key presses by the user. If a memo editor accepts returns (RepositoryItemMemoEdit.AcceptsReturn is true), inserting carriage-return/linefeed characters creates a new text line within the editor; otherwise, return key presses are processed by the form. Tabs can be used either to align text within the memo editor or move focus to another control.

Use the MemoEdit.Properties and RepositoryItem.LookAndFeel members to specify the behavior and look & feel of a memo editor.

The editor does not support editing in masked mode, therefore RepositoryItemTextEdit.Mask object settings are not in effect.

Tooltips

DevExpress controls support regular and super tooltips. If the ShowToolTips option is enabled, tooltips are shown when the mouse pointer hovers the control.

Use the following properties to specify a regular tooltip’s content:

  • ToolTip — a regular tooltip’s text. If the text is not specified, the tooltip is not displayed even if the title is specified. You can use line breaks in regular tooltips. Use the AllowHtmlTextInToolTip property to specify whether to parse HTML tags in the text. HTML tags allow you to format the text: size, style, hyperlinks, etc.
  • ToolTipTitle — a regular tooltip’s title. If the title is not specified, it is not displayed.
  • ToolTipIconType — a regular tooltip’s predefined icon. Use the controller’s IconSize property to specify the image size.

    image

    To display a custom image in all regular tooltips, use the controller’s ImageList and ImageIndex properties.

    To display a custom image in a particular regular tooltip, handle the BeforeShow event. Use the ImageOptions event argument to assign a raster or vector image to the processed tooltip.

To assign a super tooltip to a control, use the SuperTip property. Enable the AllowHtmlText property to use HTML tags in the super tooltip.

To replace regular tooltips with super tooltips, set the ToolTipController.ToolTipType property to SuperTip. The controller automatically converts regular tooltips to super tooltips. To access this property, you can use the DefaultToolTipController component or a custom controller assigned to the ToolTipController property. See Tooltips for more information.
