- editing.allowUpdating
beginCustomLoading(messageText)
Shows the load panel.
Normally, the load panel is invoked automatically while the widget is busy rendering or loading data. Additionally, you can invoke it by calling this method. If you call it without the argument, the load panel displays text specified by the loadPanel.text option. To specify the appearance of the load panel, use the loadPanel object. Once invoked from code, the load panel will not hide until you call the endCustomLoading() method.
See Also
beginUpdate()
Prevents the widget from refreshing until the endUpdate() method is called.
The beginUpdate() and endUpdate() methods prevent the widget from excessive updates when you are changing multiple widget settings at once. After the beginUpdate() method is called, the widget does not update its UI until the endUpdate() method is called.
See Also
byKey(key)
A Promise that is resolved after the data object is loaded. It is a native Promise or a jQuery.Promise when you use jQuery.
The following code shows how to get a data object whose key is 15.
widgetInstance.byKey(15).done(function(dataObject) { // process "dataObject" }).fail(function(error) { // handle error });
