DxTreeList.ColumnCaptionAlignment Property

Specifies the alignment of all column captions.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(null)]
[Parameter]
public TreeListTextAlignment? ColumnCaptionAlignment { get; set; }

Property Value

Type	Default	Description
Nullable<TreeListTextAlignment>	null	An enumeration value.

Available values:

Name	Description
Auto	Aligns text based on cell content and column data type.
Left	Aligns cell text to the left.
Center	Centers cell text.
Right	Aligns cell text to the right.

Remarks

The TreeList component automatically aligns cell values depending on data types. For example, numeric values are aligned to the right in their cells. Note that the TreeList component does not change caption alignment in the same manner. You can use the ColumnCaptionAlignment property to align caption text. You can specify the DxTreeListColumn.CaptionAlignment property to override this setting on a column level. Note that these properties do not affect the selection column.

The following code snippet centers all captions:
