    <p>I am porting quite a huge piece of software to an ExtJS Grid. Lots of data (and I mean lots of data) is loaded on-demand into spans that are placed inside grid's cells.</p> <p>Imagine grid cells having <code>&lt;span id="foo_bar'&gt;&lt;/span&gt;</code> as content, and special ajax handlers are polling the backend for updated information and once available the spans are filled with it.</p> <p>Now, in case I collapse some part of the grid and then re-exand them again I loose all automatically filled cell content, and am left with empty spans (which I started from in the first place).</p> <p>I know the correct way is to setup a store and push all data into the store. But as I've mentioned above: I am porting quite a huge piece of legacy software to ExtJS, and I do not really have much choice here.</p> <p>Is there a way to automagically push grid cell values to the store?</p> <p><strong>Update:</strong></p> <p>A grid is loaded with, suppose, 2000 cells (this can vary tremendously). Every cell contains various grades of HTML, mostly this is , but this can be pretty much anything (including several spans or divs in one cell). In the background there is a comet process pushing new data to the HTML page almost in real time. This data is populated to the corresponding SPANS and DIVs either based on their IDs or class or both.</p> <p>What I want to achieve is that either: a) the model for the grid is atomagically updated with the new html content of the cells (how can I achieve this)? b) when collapsing/expanding tree's nodes the model data is NOT reloaded afresh. </p> <p>Is either a or b possible? if so — how?</p>

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.
