TableColumnCollection Class

Provides standard facilities for creating and managing a type-safe, ordered collection of TableColumn objects.

Namespace:  System.Windows.Documents
Assembly:  PresentationFramework (in PresentationFramework.dll)

public sealed class TableColumnCollection : IList<TableColumn>, 
	ICollection<TableColumn>, IEnumerable<TableColumn>, IList, 
	ICollection, IEnumerable
You cannot directly create an instance of this class in XAML.

This collection supports standard zero-based indexing.

The Columns property provided by the Table class returns a TableColumnCollection. For more information, see How to: Manipulate a Table's Columns through the Columns Property.

This example demonstrates some of the more common operations that can be performed on a table's columns through the Columns property.

The following example creates a new table and then uses the Add method to add columns to the table's Columns collection.

Table tbl = new Table();
int columnsToAdd = 4;
for (int x = 0; x < columnsToAdd; x++)
    tbl.Columns.Add(new TableColumn());

The following example inserts a new TableColumn. The new column is inserted at index position 0, making it the new first column in the table.


The TableColumnCollection collection uses standard zero-based indexing.

tbl.Columns.Insert(0, new TableColumn());

The following example accesses some arbitrary properties on columns in the TableColumnCollection collection, referring to particular columns by index.

tbl.Columns[0].Width = new GridLength(20);
tbl.Columns[1].Background = Brushes.AliceBlue;
tbl.Columns[2].Width = new GridLength(20);
tbl.Columns[3].Background = Brushes.AliceBlue;

The following example gets the number of columns currently hosted by the table.

int columns = tbl.Columns.Count;

The following example removes a particular column by reference.


The following example removes a particular column by index.


The following example removes all columns from the table's columns collection.



Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
