Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v19.1.dll

Declaration

C#

[Browsable(false)]
public bool IsDisplayTextValid { get; }

VB.NET

<Browsable(False)>
Public ReadOnly Property IsDisplayTextValid As Boolean

Property Value

Type	Description
Boolean	true, if the text in the edit box matches the RepositoryItemLookUpEditBase.DisplayMember field value of any row in the dropdown; otherwise, false.

Remarks

When the incremental filtering or automatic completion feature is enabled, the editor allows you to select rows from the dropdown by entering them within the edit box. When changing the display text, the editor searches for the record whose RepositoryItemLookUpEditBase.DisplayMember field value starts with the entered characters. If such record is found, the editor completes the text. The IsDisplayTextValid property returns true in this instance. If a match was not found, the property returns false thus indicating that the text does not correspond to any row.

See RepositoryItemLookUpEdit.SearchMode to enable incremental filtering or the automatic completion feature.

You rarely need to use the property in your code. IsDisplayTextValid is mostly used internally.
