We are using Grids and Stores to make server side request and display there results. The grids and stores work well for us when there are no errors on the server, but we need to correctly handle errors from the server when they occur. Currently the grids display either “an error occurred” or “no data found” when we have problems on the server.

What is the recommended technique for adding custom “error handlers” to dojo grids and/or stores so that we can display appropriate messages to the user?

Hi all,

I've rolled by own custom data store based on the following demo:

http://archive.dojotoolkit.org/dojo-2008-02-19/dojotoolkit/dojox/data/de...

Hello all, i am changing the model of a grid using the setModel method of the grid and then calling the refresh method to update data.

Hello,
I've searched for a while and couldn't find something that discuss this issue. If so I'm sorry for this unnecessary thread.

When adding a filteringselect widget programmatically with an existing datastore, it starts a query to the store and creates a ajax request to the server even though there is no value set. Is there a possibilty to change the onload behaviour of this widget?

The problem is that I have a form with lots of filteringselects connected to the same datastore, and the pageloading time is correspondingly very long, when it always starts a request.

Hello,

I'm trying to create a store using JsonRPC to be used with a Grid.
Anyone tried this? Could it be a simple copy/paste of the JsonRestStore and simply use dojox.rpc.JsonRPC?

Thanks

Hi !

I've spend about 3hr to found out why the onSet event is never fired, I, desperatly, I ask for your help :)

So, here is my code :

function createGrid (oResponse, ioArgs) {
var grid = dijit.byId("grid");
var store = new dojo.data.ItemFileReadStore({data: oResponse });
var gridModel = new dojox.grid.data.DojoData(null, store, {query:{destination: '*'}, clientSort:true});
grid.setModel(gridModel);
grid.refresh();

dojo.connect(grid.model, 'onSet', onSetEvent);
//dojo.connect(grid, 'onSet', onSetEvent);
}

Hi master,

How can i constructe a tree dynamically with database information.

Hi All,
Can anyone help me in recognising the problem with this code?..

I have copied the code from "dojox\data\demos\demo_QueryReadStore_grid.html". I made very little modification i.e I removed one grid as I needed only one grid. Now my problem is sorting is not happening for any of the categories and I am not able to understand how and where to make a call to the server for paginitaion functionality. Server will just send me an collection..

Thanks in advance.

The two functions below are two different attempts to programmatically create a filteringSelect and its associated data store. I believe I am not properly creating the data store. The first method...


function createPicklist(elemId, fldLabel, fldCount) {
showMsg("creating picklist for:\nnelemId:" + elemId + "\nlabel:" + fldLabel + "\ni:" + i);
// This function creates a filteringSelect element for the specified field from the database
