Range.ColumnWidth Property
Gets or sets the width of columns that comprise the cell range in units of measurement used in the workbook.
Namespace: DevExpress.Spreadsheet
Assembly: DevExpress.Spreadsheet.v19.1.Core.dll
Declaration
Property Value
| Type | Description |
|---|---|
| Double | A Double value that is the column width in units of measurement that are in effect. |
Remarks
Use the Column.WidthInPixels property to set or obtain a column width in pixels.
To specify the column width in characters of the default font specified by the built-in Normal style, use the Range.ColumnWidthInCharacters property.
If columns containing the cell range have different widths, the ColumnWidth and Range.ColumnWidthInCharacters properties return the width of the left column.
Example
This example demonstrates how to control the column width on a worksheet.
Set the Width for Individual Columns
To specify a column width in characters of the default font specified by the built-in Normal style, use the column’s Column.WidthInCharacters property, or the Range.ColumnWidthInCharacters property of the cell or cell range object.
To specify a column width in pixels, use the column’s Column.WidthInPixels property.
To set a column width in other measurement units, first set the IWorkbook.Unit property to the DocumentUnit enumeration member that corresponds to the desired units, then use the column’s Column.Width property, or the
Range.ColumnWidthproperty of the cell or cell range object.Note
If a column width is set to 0, the column is hidden. You can also use the Column.Visible property to hide a column or display the hidden column again (see the How to: Show or Hide a Row or Column document).
AutoFit Column Width
To automatically change the column width to fit the contents, use the columns’s Column.AutoFit method. To quickly autofit several columns on a worksheet, use the ColumnCollection.AutoFit method.
Match the Width of Two Columns
To match one column width to another, you can use the Column.Width property or Range.CopyFrom method of the column object.
Set the Default Column Width
To set the default width for worksheet columns, use the Worksheet.DefaultColumnWidthInCharacters, Worksheet.DefaultColumnWidthInPixels or Worksheet.DefaultColumnWidth property. These properties do not affect columns with an explicitly specified width.
Set the Width for All Columns on a Worksheet
To change the width of all columns on a worksheet, use the Range.ColumnWidthInCharacters or
Range.ColumnWidthproperty of the Row object corresponding to any row on a worksheet. This sets the width of all columns to the same value, overriding all previously applied column width settings.

// Set the "B" column width to 30 characters of the default font that is specified by the Normal style.
worksheet.Columns["B"].WidthInCharacters = 30;
// Set the "C" column width to 15 millimeters.
workbook.Unit = DevExpress.Office.DocumentUnit.Millimeter;
worksheet.Columns["C"].Width = 15;
// Set the width of the column that contains the "E15" cell to 100 points.
workbook.Unit = DevExpress.Office.DocumentUnit.Point;
worksheet.Cells["E15"].ColumnWidth = 100;
// Set the width of all columns that contain the "F4:H7" cell range (the "F", "G" and "H" columns) to 70 points.
worksheet.Range["F4:H7"].ColumnWidth = 70;
// Set the "J" column width to the "B" column width value.
worksheet.Columns["J"].Width = worksheet.Columns["B"].Width;
// Copy the "C" column width value and assign it to the "K" column width.
worksheet.Columns["K"].CopyFrom(worksheet.Columns["C"], PasteSpecial.ColumnWidths);
// Set the default column width to 40 pixels.
worksheet.DefaultColumnWidthInPixels = 40;
