DxGridColumn.Caption Property

Specifies the column’s caption.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v22.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(null)]
[Parameter]
public string Caption { get; set; }

Property Value

Type	Default	Description
String	null	The column’s caption.

Remarks

Use the Caption property to specify a custom column caption.

If you do not set this property, the Grid generates a user-friendly column caption based on the assigned field’s name (the FieldName property value). The Grid adds space characters between parts of the field name that begin with uppercase letters. For instance, the “Cloud Cover“ caption is displayed for the CloudCover field.
