Açıklamalar

, GridTableStylesCollection denetimin DataGrid içindeki her DataTableDataSetbiri için özelleştirilmiş bir kılavuz stili görüntülemesine olanak tanıyan nesneler içerirDataGridTableStyle.

denetiminde DataGridTableStyles özelliği döndürür GridTableStylesCollection.

Varsayılan olarak, GridTableStylesCollection herhangi bir DataGridTableStyle nesne içermez. Bunun yerine, DataGrid her tabloyu renk, genişlik ve biçimlendirme için varsayılan ayarları kullanarak görüntüler. Her tablonun tüm sütunları görüntülenir. koleksiyona bir DataGridTableStyle eklendiğinde, DataGridMappingName kılavuz için verileri hangi nesnenin sağladığını belirlemek için kullanır. Örneğin, veri kaynağı üç DataTable nesne içeren bir DataSet ise, MappingName nesnelerden birinin eşleşmesi TableName gerekir. MappingName değeri herhangi bir değerle TableName eşleşmiyorsa, her tablonun verilerini görüntülemek için varsayılan ayarlar kullanılır ve DataGridTableStyle ayarlar yoksayılır.
