GridControl.CalcBestSize(Size, Boolean) Method

Calculates the grid size required to fit its content or to display the maximum number of rows and columns. The size cannot exceed the specified maximum size.

Namespace: DevExpress.XtraGrid

Assembly: DevExpress.XtraGrid.v25.1.dll

NuGet Packages: DevExpress.Win.Grid, DevExpress.Win.Navigation

Declaration

C#

public Size CalcBestSize(
    Size maxSize,
    bool checkScrollInfo = false
)

VB.NET

Public Function CalcBestSize(
    maxSize As Size,
    checkScrollInfo As Boolean = False
) As Size

Parameters

Name	Type	Description
maxSize	Size	The maximum allowed size.

Optional Parameters

Name	Type	Default	Description
checkScrollInfo	Boolean	False	true to include the size of scrollbars into the calculation; otherwise, false.

Returns

Type	Description
Size	The optimal grid size required to fit its content.

Remarks

You can use the CalcBestSize method to resize the grid to its optimal size. In this case, you must call this method twice: to calculate the grid size and to include scrollbars in the calculation (they may appear/disappear after the first resize).

C#

gridControl1.Size = gridControl1.CalcBestSize(new System.Drawing.Size(1600, 1200), false);
gridView1.LayoutChanged();
gridControl1.Size = gridControl1.CalcBestSize(new System.Drawing.Size(1600, 1200), true);
gridView1.LayoutChanged();

VB.NET

gridControl1.Size = gridControl1.CalcBestSize(New System.Drawing.Size(1600, 1200), False)
gridView1.LayoutChanged()
gridControl1.Size = gridControl1.CalcBestSize(New System.Drawing.Size(1600, 1200), True)
gridView1.LayoutChanged()

You can also call the GridView.BestFitColumns method to resize grid columns to the optimal width.

Usage Notes

• The CalcBestSize method supports only GridView and its descendants.
• The CalcBestSize method ignores group row content and the Group Panel width.
• In master-detail mode, the CalcBestSize method calculates the optimal width only for the master view.
