This documentation topic describes legacy technology. We no longer develop new functionality for the
GridControl and suggest that you use the new DataGridView control instead.
GridControl is a data bound control that provides a set of data shaping and manipulation features, including data sorting, grouping, filtering and summary calculation.
To get started with GridControl, see the Getting Started tutorial.
This example shows how to add columns to
GridControl to display and edit data of different types. The grid is bound to a collection of Employee objects. Each Employee object contains an employee’s photo (image), name, position, phone, address (strings), hire and birth dates (DateTime values), a value that specifies an employee’s access level, and a Boolean value indicating whether an employee is on vacation.
Grid columns are stored in the GridControl.Columns collection. An individual column is specified by a GridColumn descendant, which is appropriate to the type of data contained in this column. In this example, to display information on employees and allow end-users to edit it, the following columns are created in the grid.
This column displays employee photos which are images added to a project as embedded resources.
A cell in this column displays three employee properties: Name, Position and HireDate. A cell appearance is defined via a template. Each cell contains three Xamarin.Forms.Label elements within a Xamarin.Forms.Grid. Each Label element is bound to a property of the Employee class.
A cell template data context is specified by the CellData object. Its CellData.Value property provides access to a value of a data field assigned to the column’s GridColumn.FieldName property. In this example, a column cell displays not only this field value but also values of two more fields. So, it is required to specify the whole data row as a binding source for the template. To do this, set the BindingContext property of the Grid to CellData.Source. Note that BindingContext specified for the Grid is inherited by all its children. This means that all Label elements have the same BindingContext as the Grid, and you can specify their simple bindings to properties of that object (Employee).
The employee’s Phone property is of the string type. The keyboard allowing text input is automatically displayed when an end-user activates this column cell to edit an employee’s phone.
This column is bound to the employee’s Address string property. The keyboard allowing text input is automatically displayed when an end-user activates this column cell to edit an employee’s address.
This column displays and allows editing employee birth days. The GridColumn.DisplayFormat property specifies the format of displaying dates.
The employee’s Access property is of the AccessLevel type which is an enumeration with values Admin and User. To allow editing an employee’s access level by selecting one of two enumeration values, this property is bound to the grid’s picker column.
The employee’s OnVacation property is of the Boolean type, so it is bound to the grid’s switch column which allows editing a cell value by selecting between two states.
