    <p>I am new to Ext so I apologize in advance if my question is not clear enough/too basic...</p> <p>I have an Ext.grid.EditorGridPanel with an Ext.data.Store and an Ext.data.JsonReader.</p> <p>I have the following problem:</p> <p>I would like to make the columns in my grid sortable but the value returned from my store is not the value I'd like to sort by (the value returned is an ID and I'd like to sort by the string this ID maps to).</p> <p>I have a render function that converts between this ID and the string value but I don't know how to integrate this into my code.</p> <p>I have found this post:</p> <p><a href="http://www.sencha.com/forum/showthread.php?45324-Grid-column-sorting-on-rendered-value" rel="nofollow">http://www.sencha.com/forum/showthread.php?45324-Grid-column-sorting-on-rendered-value</a></p> <p>which looked similar to my need but when I tried adding:</p> <pre><code>{name: 'my_field', sortType: my_render_function} </code></pre> <p>to my JsonReader it did not work.</p> <p>Where do I get it wrong?</p> <p>Thanks.</p> <hr> <p>For Pater's request:</p> <pre><code>var my_render = function(val, metaData, record, rowIndex, colIndex, store){ if (val == null) return ''; var n = another_store.getById(val); if (n == null) return ''; return n.data.name; }; var my_reader = new Ext.data.JsonReader({ root: 'my_root', id: 'tissue_num', }, [{ name: 'tissue_num', type: 'int' }, 'tissue_desc', 'organ'] ); var my_store = new Ext.data.Store({ url: request_url, baseParams: { _state: request_state, _action: 'get_conditions' }, sortInfo: { field: 'tissue_num', direction: "ASC" }, reader: my_reader, pruneModifiedRecords: true }); </code></pre>

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).
