The Popup Edit Form allows end-users to edit column values in a popup.
To enable the Popup Edit Form mode, set the DevExpress ASP.NET Grid View’s (ASPxGridView) SettingsEditing.Mode option to PopupEditForm.
ASPxGridView's popup edit form automatically rearranges its content in response to browser window resizing (the SettingsPopup.EditForm.SettingsAdaptivity.Mode property controls this behavior). In adaptive mode, the popup's fields are positioned one under another and in one column when a browser window’s width is less than or equal to the value specified in the SettingsPopup.EditForm.SettingsAdaptivity.SwitchAtWindowInnerWidth property.
The Popup Edit Form can also be displayed as a modal dialog. In this mode, the edit form must be closed before returning to the application (the SettingsEditing.PopupEditFormModal option controls this behavior).
In this example, you can specify whether to use a modal popup via the Show Popup Edit form in modal mode checkbox and control the ‘Notes’ field's position using the Show memo at bottom checkbox.
