    <p>Before we start: I noticed the configuration object for your grid has </p> <pre><code>xtype:'grid' </code></pre> <p>This, by itself, forbids any editing capability and server interactions (besides reading the store), because you are instancing an <strong>Ext.grid.GridPanel</strong>, while (I think) you need an <strong>Ext.grid.EditorGridPanel</strong>. For all of the following to run properly, you should change this line to:</p> <pre><code>xtype:'editorgrid' </code></pre> <p>First thing I would check is that the store has an <strong>id</strong> configuration attribute, and it is a configured column of the store reader. If the store cannot identify the record, it will think that the record does not exist, and will not generate a request to the server.</p> <p>Second thing to check: has your store been configured to generate server requests? That is, is there a line like this in your store config object?</p> <pre><code>proxy: new Ext.data.HttpProxy({ api:{ read:'readscript.url', create:'insertscript.url', update:'updatescript.url', destroy:'deletescript.url' } }) </code></pre> <p>Next, have you defined the "<strong>writer</strong>" attribute in your store configuration object? The store config object should have a <strong>proxy</strong> and a <strong>writer</strong> attribute to generate proper server requests upon deletion.</p> <p>To specify a writer for the store you may simply write (for a common Json writer):</p> <pre><code>writer: new Ext.data.JsonWriter() </code></pre> <p>and the store will send all the appropriate write requests to the server.</p> <p>Another painful (not well documented, I think) issue could be the presence of mandatory fields in the store reader. All columns are mandatory by default; to mark a column as "non-mandatory" you must specify (in the store reader column array):</p> <pre><code>{name:'column_name', allowBlank:true, /* other stuff like 'type' etc. */ } </code></pre> <p>Probably, when you add a new record to the grid, not all of the columns will be populated. The store will not generate a server create request until all mandatory columns are populated. Then, if you delete an unsaved record, the store will not generate the destroy request because it will assume that the record "does not exist".</p>

    1. COthanks a lot.but the "proxy" element of grid gives me some error.but i have solved this by using a small ajax code. var g1 =Ext.getCmp('mygrid'); var dataid= g1.getSelectionModel().getSelected().id; Ext.Ajax.request({ url: '/products/'+dataid, method: 'DELETE', params: {'data[id]':dataid} });

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.
