The DevExpress ASP.NET Grid View (ASPxGridView) provides the capability to allow end-users to select rows using checkboxes. To do this, add a command column to the ASPxGridView and set its ShowSelectCheckBox property to ‘true’. The column will display check boxes within its cells. End-users can check or uncheck these check boxes to select or de-select the corresponding data rows.
This demo illustrates how you can display contact names selected within the ASPxGridView in a list box. The client-side SelectionChanged event is handled to display the selected contacts in the list box, and the total number of selected contacts below the list box. Contact names are obtained using the GetSelectedFieldValues function. The number of selected rows is returned by the GetSelectedRowCount client function.
