But the larger difference lies in their respective programming models. Unlike the GDI, which uses a stateful model, the GDI is mostly stateless. A traditional Windows application programs values such as fonts and text colors into a device context. A Windows Forms application doesn t. It passes parameter.

Sortable DataGrid Controls By default, items appear in a DataGrid in the same order in which they re enumerated from the data source. You can sort the contents of a DataGrid by binding to a DataView instead of a DataReader or DataSet. DataView is an ADO. NET class used to create logical views of the records in a data source. A DataView can be sorted by assigning a sort expression t. windows server 2012 standard evaluation key.

NET can t know definitively when a session is no longer needed because it has no way of knowing whether a given request is that user s last. So it does the next best thing if a prescribed time period elapses and ASP.

When items are removed, items with higher indexes are automatically shifted down to fill the void. If you delete the item at index 5, for example, Windows 8 Standard , the item at index 6 becomes the item at index 5, the item at. server 2012 standard evaluation key - r is slightly different from traversing a tree of nodes in an XmlDocument.
