GridColumnStylesCollection Class

Represents a collection of DataGridColumnStyle objects in the System.Windows.Forms.DataGrid control.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public class GridColumnStylesCollection : BaseCollection, 
	IList, ICollection, IEnumerable

On the DataGridTableStyle, you access the GridColumnStylesCollection through the GridColumnStyles property.

The GridColumnStylesCollection uses standard Add and Remove methods to manipulate the collection.

Use the Contains method to determine if a specific property value exists in the collection. Additionally, use the IndexOf method to determine the index of any DataGridColumnStyle object within the collection.

Caution noteCaution:

   Always create DataGridColumnStyle objects and add them to the GridColumnStylesCollection before adding DataGridTableStyle objects to the GridTableStylesCollection. When you add an empty DataGridTableStyle with a valid MappingName value to the collection, DataGridColumnStyle objects are automatically generated for you. Consequently, an exception will be thrown if you try to add new DataGridColumnStyle objects with duplicate MappingName values to the GridColumnStylesCollection.

The following code example prints information about each DataGridColumnStyle in a GridColumnStylesCollection.

private void PrintColumnInformation(DataGrid grid){
   Console.WriteLine("Count: " + grid.TableStyles.Count);
   GridColumnStylesCollection myColumns;   
   foreach(DataGridTableStyle myTableStyle in grid.TableStyles){

      myColumns = myTableStyle.GridColumnStyles;

      /* Iterate through the collection and print each 
      object's type and width. */ 
      foreach (DataGridColumnStyle dgCol in myColumns){
