    <p>I have an OnDemandGrid setup to display product data (called parts) for a project i am working on. I currently have only two entries in the product database. </p> <p>My OnDemandGrid is setup with only the basic options: store, and columns. I am hoping it will be a virtual scrolling grid. the store was setup as a JsonRest store, with Cache </p> <p>what happens when i open up the page and startup the grid is, the grid keeps sending requests to the server for data continuously - approximately 2 requests per second. </p> <p>I also realize that for a grid with only two rows, it has a scrollbar on the right. when i try to use this scrollbar to scroll, I find that the grid seems to flicker and reset itself. many times. </p> <p>I suspect the virtual scroll feature is doing something funky, somehow not acknowledging that there are only two entries. can some one help me out in this? am willing to provide more details should that be necessary. </p> <p>Here is my code by the way:</p> <pre><code>require(["dgrid/OnDemandGrid", "dojo/store/Memory", "dojo/store/Cache"], function(OnDemandGrid, Memory, Cache){ var partsCache = new Memory(); App.Store.parts = new Cache(partsMaster, partsCache); var grid = new OnDemandGrid({ store: App.Store.parts, columns: { name:'Part Name', part_no:'Part Number' }, }, "grid"); grid.startup(); }) </code></pre> <p>partsMaster is a JsonRest store defined earlier (global at the moment - taking the grid for a spin) in the code. I've done some tests to safely determine that JsonRest is not the issue.</p> <p>here is a screenshot of the grid currently (note the existence of the scrollbar): <img src="https://i.stack.imgur.com/JoA1C.png" alt="enter image description here"></p> <p>Any help is appreciated!</p> <p>EDIT: attached is a screen shot of the first request response header from chrome: <img src="https://i.stack.imgur.com/Sgm2N.png" alt="enter image description here"></p>

    1. COCan you also provide information on the first few queries sent to the server for the store? Specifically, include the request and response headers. The most common problem here is that the service isn't setting the Content-Range header properly.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
