CreateRowFromColumns Method

Overview

The CreateRowFromColumns method creates a new IObservableDataRow instance from a list of column metadata. The created row contains one field per column name and all fields are initialized to null.

If you want the row fields to be initialized with default values (for example, 0 for numeric types), use the CreateRowFromColumnsWithDefaultValues method instead.

Declaration

/// <summary>
/// Creates detached observable row without any values from columns metadata
/// </summary>
/// <param name="listOfColumnMetadata">List of column metadata</param>
/// <returns>Created row</returns>
public static IObservableDataRow CreateRowFromColumns(List<IColumnMetadata> listOfColumnMetadata)

Namespace and Assembly

Namespace: PocoDataSet.ObservableExtensions
Assembly: PocoDataSet.ObservableExtensions.dll

Usage Example

// 1. Create a new observable data set
IObservableDataSet observableDataSet = new ObservableDataSet();

// 2. Create a table and define its columns
IObservableDataTable departmentObservableDataTable = observableDataSet.AddNewTable("Department");
departmentObservableDataTable.AddColumn("Id", DataTypeNames.INT32);
departmentObservableDataTable.AddColumn("Name", DataTypeNames.STRING);

// 3. Create detached row without any values from the table columns
IObservableDataRow departmentObservableDataRow = ObservableDataRowExtensions.CreateRowFromColumns(departmentObservableDataTable.Columns);
