Namespace: DevExpress.XtraEditors.Repository

Assembly: DevExpress.XtraEditors.v24.2.dll

Declaration

[DefaultValue(true)]
[DXCategory("Behavior")]
public virtual bool ShowHeader { get; set; }

VB.NET

<DXCategory("Behavior")>
<DefaultValue(True)>
Public Overridable Property ShowHeader As Boolean

Property Value

Type	Default	Description
Boolean	true	true if column headers are visible; otherwise, false.

Remarks

The ShowHeader property determines the visibility of the column header panel. The panel displays column captions specified by the LookUpColumnInfo.Caption properties. If an incremental search is being performed, a search glyph (binoculars) is displayed in the appropriate column header. The incremental search is available when the RepositoryItemLookUpEdit.SearchMode property is set to SearchMode.AutoComplete or SearchMode.OnlyInPopup. The incremental search column is identified by the RepositoryItemLookUpEdit.AutoSearchColumnIndex property. The end-user can click on a column header and thus select another column for the search.

See the RepositoryItemLookUpEditBase.ShowFooter property to specify the visibility of the footer region.

The images below show lookup editors when the header panel is visible and hidden.
