TreeListOptionsColumn.AllowEdit Property

Specifies if users can edit column values in tree list cells (inplace edit mode).

Namespace: DevExpress.XtraTreeList.Columns

Assembly: DevExpress.XtraTreeList.v24.2.dll

Declaration

C#

[DefaultValue(true)]
[XtraSerializableProperty]
public virtual bool AllowEdit { get; set; }

VB.NET

<DefaultValue(True)>
<XtraSerializableProperty>
Public Overridable Property AllowEdit As Boolean

Property Value

Type	Default	Description
Boolean	true	true to allow users to edit cell values; otherwise, false.

Property Paths

You can access this nested property as listed below:

Object Type	Path to AllowEdit
TreeListColumn	.OptionsColumn .AllowEdit

Remarks

The AllowEdit option is in effect if the tree list’s TreeList.OptionsBehavior.Editable property is set to true and the EditingMode property is set to Default or Inplace.

Handle the TreeList.ShowingEditor event to prevent a user from changing the value in individual cells. This event occurs when an inplace editor is about to open, and allows you to cancel this action.
