TableStyleCollection.Contains(String) Method

Indicates whether the collection contains the table or PivotTable style with the specified name.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v24.2.Core.dll

NuGet Package: DevExpress.Spreadsheet.Core

Declaration

C#

bool Contains(
    string name
)

VB.NET

Function Contains(
    name As String
) As Boolean

Parameters

Name	Type	Description
name	String	A String value that specifies the name of the style to locate in the collection.

Returns

Type	Description
Boolean	true, if the collection contains the table or pivot table style under the specified name; otherwise, false.

Example

This example demonstrates how to create a custom style to format tables.

1. Add a new table style to the IWorkbook.TableStyles collection by calling the TableStyleCollection.Add method with the table style name passed as a parameter. This method returns the TableStyle object that represents the newly created table style. This object’s TableStyle.Name property is set to the specified name. Other settings are identical to the None table style (the default built-in table style that specifies no formatting for a table).

   Note

   Note that table styles have unique names in the collection. To ensure that there is no table style under the specified name in the collection, use the TableStyleCollection.Contains method.

2. Modify elements of the created table style (TableStyle.TableStyleElements) within the TableStyle.BeginUpdate and TableStyle.EndUpdate paired methods.
