Loading Panel

The Loading Panel is displayed within the FileManager extension while waiting for a callback response. Under the loading panel, a Loading Div element covering the file manager can be displayed. This element is transparent by default. Specify the element's style settings to show it.

If the FileManagerSettingsFolders.EnableCallBacks (via the FileManagerSettings.SettingsFolders.EnableCallBacks) property is set to true, the first expansion of a folder initiates a callback to the server to obtain the folder's child folders. In this case, a specific Node Loading Panel is displayed near the folder being expanded while waiting for a callback response.

The table below lists the main members that affect element appearance and functionality.
