OptionsColumn.AllowMerge Property

Gets or sets whether neighboring cells with identical values can be merged within the current column.

Namespace:DevExpress.XtraGrid.Columns
Assembly:DevExpress.XtraGrid.v17.1.dll

Expanded Syntax

Property value

Type: DefaultBoolean
A DevExpress.Utils.DefaultBoolean enumeration value which specifies whether neighboring cells with identical values can be merged.
The default is DefaultBoolean.Default.

Expanded Remarks

Cell merging is enabled if the GridOptionsView.AllowCellMerge property is set to true.

By default, all the columns in a View have their AllowMerge properties set to DevExpress.Utils.DefaultBoolean.Default. In this case, cells will be only merged in sortable columns (the columns that use certain in-place editors). Cells will not be merged in the columns that use a PictureEdit, ImageEdit or MemoExEdit editor.

If the AllowMerge property is set to DevExpress.Utils.DefaultBoolean.True the grid will try to merge neighboring cells if they have matching values. Setting this property to DevExpress.Utils.DefaultBoolean.True is in effect for the columns that use the MemoExEdit in-place editor.

If the AllowMerge property is set to DevExpress.Utils.DefaultBoolean.False the cell merging feature is disabled for this column.

Refer to the Cell Merging Overview document for more information on the cell merging functionality.
