System::ComponentModel::Container^ components Public ref class Form1: public System::Windows::Forms::Form #ADDING GRIDS TO WINDOWS CODE#The example also contains code in the MouseUp event that uses the HitTest method to print the column, row, and part of the grid that has been clicked. A button on the form changes the appearance of the grid by creating two DataGridTableStyle objects and setting the MappingName of each object to a TableName of one of the DataTable objects. To display the data, a control is then bound to the DataSet through the SetDataBinding method. The following code example creates a Windows form, a DataSet containing two DataTable objects, and a DataRelation that relates the two tables.
