View Full Version : GridPanel and error handling

12 Oct 2010, 6:32 AM
I have a gridpanel with a data store that loads data to remote server:

Now when there is an error on store loading the mask remains visible on the grid panel
I would ask how,if there is an error , I can removes the mask and in the gridpanel keep data of the last success loading.
My code is :

callback: function(records, options, success) {
if (success) {
} else {
//Remove the mask
//Keep the last data

Many Thanks

The mask should automatically be removed even in case of a loading error... are you manually masking the grid or you are using loadMask: true on the grid?

I use loadMask:true

I use this

var myMask = new Ext.LoadMask(Ext.getBody(), {msg: "???? ???? ? ???????? ??????, ?????????? ?????????..."});
Ext.Ajax.on('beforerequest', myMask.show, myMask);
Ext.Ajax.on('requestcomplete', myMask.hide, myMask);
Ext.Ajax.on('requestexception', myMask.hide, myMask);

All work fine

@psmacarov, I only dislike the fact that it's blocking the entire UI on each ajax requests...

@pibree, when you say when there is an error... do you mean that there is a javascript uncaught error, or that the exception event fires on the store? If there is an uncaught javascript error, any javascript code might stop executing, causing the mask to stay visible...

I mean an error that like web server down , Internet access is falling down etc...
