LayoutViewColumn.LayoutViewField Property
Gets the layout field that corresponds to the current column.
Namespace: DevExpress.XtraGrid.Columns
Assembly: DevExpress.XtraGrid.v24.2.dll
Declaration
[DefaultValue(null)]
[DXCategory("Behavior")]
public LayoutViewField LayoutViewField { get; set; }Property Value
| Type | Default | Description |
|---|---|---|
| LayoutViewField | null | A LayoutViewField object that corresponds to the current column. |
Remarks
For each column object in a Layout View, a layout field is created. Column objects only store various settings that affect the data display, while layout fields define the layout of cells (column data) within a card. The LayoutViewField property allows you to access the layout field corresponding to the current column.
To customize the field layout at runtime, use the LayoutView.TemplateCard property and methods provided by LayoutViewField objects.
Example
The following example shows how to create and customize a Layout View in code. In the example, a template card is created, consisting of six fields arranged as in the image below:
Before arranging layout fields in code, ensure that corresponding columns are visible (see LayoutViewColumn.Visible and GridColumnCollection.AddVisible).
