Exemplos

O exemplo de código a TableStyles seguir cria dois DataGridTableStyle objetos e adiciona cada um ao GridTableStylesCollection retornado pela propriedade de um DataGrid controle.

     to the name of a DataColumn in the DataTable.

Comentários

O GridTableStylesCollection contém DataGridTableStyle objetos que permitem que o DataGrid controle exiba um estilo de grade personalizado para cada DataTable um em um DataSet.

DataGrid No controle , a TableStyles propriedade retorna o GridTableStylesCollection.

Por padrão, o GridTableStylesCollection não contém nenhum DataGridTableStyle objeto. Em vez disso, o DataGrid exibe cada tabela usando configurações padrão para cor, largura e formatação. Todas as colunas de cada tabela são exibidas. Quando um DataGridTableStyle é adicionado à coleção, o usa o DataGridMappingName para determinar qual objeto fornece os dados para a grade. Por exemplo, se a fonte de dados for um DataSet que contém três DataTable objetos, o MappingName deverá corresponder ao TableName de um dos objetos. Se o MappingName não corresponder a TableName nenhum dos valores, as configurações padrão serão usadas para exibir dados para cada tabela e as DataGridTableStyle configurações serão ignoradas.
