PartialUpdatePanel Description

The goal of PartialUpdatePanel is the development of a component that really renders only the partial contents. This will increase the rendering speed and unload server resources. The PartialUpdatePanel supports: - Maintaining the viewstate. The viewstate of the partial content will be maintained during postbacks. Because evey PatialUpdatePanel manages it's own viewstate, less data is transfered between client and server than the AJAX UpdatePanel does. - PostBacks from childcontrols. Full postback support with event handling. - Parameters can be declared which will be transfered as GET-Parameters to the control. These parameters can be modified during runtime via JScript. - Autorefreshing the content every n milliseconds - Render the control initially synchronous (with all other controls on the page) or asynchronous (the page is sent to the client which requests the control to load) - Automatically execute JavaScript snippets from your Control via ScriptManager.RegisterStartupScript or ScriptManager.RegisterClientScriptBlock - Set a timeout after the LoadingTemplate should be shown - You can use controls from the AJAX Control Toolkit inside the PartialUpdatePanel - Globalization - Encrypt path to your UserControl - Using custom ScriptManagers (including ToolkitScriptManager) - Using ToolkitScriptManager.CombineScriptsHandlerUrl - Change UserControl path during runtime via JavaScript
