AutoGenerateColumns Property (DefaultSheetDataModel)

Gets or sets whether to generate the columns automatically based on the data source.

Syntax

Visual Basic
C#

'Declaration
 
Public Property AutoGenerateColumns As Boolean

'Usage
 
Dim instance As DefaultSheetDataModel
Dim value As Boolean
 
instance.AutoGenerateColumns = value
 
value = instance.AutoGenerateColumns

public bool AutoGenerateColumns {get; set;}

Property Value

Boolean: true, for automatic generation, false otherwise

Example

This example creates a new DefaultSheetDataModel, binds it to a database and attaches it to the DataModel of the active sheet. It does not automatically generate its columns based on the columns in the database, but does so on an individual basis.
