CompatibilitySettings.AllowInfiniteGridSize Property

Gets or sets whether to allow infinite size of the grid-based control (for example, GridControl, TreeListControl).

Namespace: DevExpress.Xpf.Core

Assembly: DevExpress.Data.Desktop.v25.1.dll

NuGet Packages: DevExpress.Data.Desktop, DevExpress.ExpressApp.Win.Design

Declaration

C#

public static bool AllowInfiniteGridSize { get; set; }

VB.NET

Public Shared Property AllowInfiniteGridSize As Boolean

Property Value

Type	Description
Boolean	true to allow a control to have an infinite size; otherwise, false.

Remarks

The AllowInfiniteGridSize property specifies whether the grid can have an infinite height and/or width.

Default Behavior

The AllowInfiniteGridSize setting is disabled.

When a grid is placed in a container without a defined size constraint, the grid throws the InfiniteGridSizeException to prevent performance issues caused by rendering all grid rows.

How to Avoid the Exception

Limit the Grid’s Height

Place the grid in a container (for example, Grid or DockPanel) that assigns a finite size to it.

Set Height or MaxHeight

Explicitly set the grid’s size or maximum allowed size (for example, Height or MaxHeight).

Allow Infinite Height

Enable the AllowInfiniteGridSize setting at application startup:

public partial class App : Application {
    static App() {
        // Allow the grid to have an infinite height (not recommended for large datasets)
        DevExpress.Xpf.Core.CompatibilitySettings.AllowInfiniteGridSize = true;
    }
}

Important

Be aware of the potential impact on performance when binding to large datasets.
