    <p>I have a combo box and a datagrid in my page. when the user changes the combo box value i have to update the grid with children details of newly selected parent. How can I achieve this using Dojo combo box and datagrid.</p> <p>the following code snippet not working for me. when I use setStore method on the grid with new json data.</p> <pre><code>&lt;div dojoType="dojo.data.ItemFileReadStore" jsId="store" url="/child/index/"&gt;&lt;/div&gt; // grid store &lt;div dojoType="dojo.data.ItemFileReadStore" jsId="parentStore" url="/parent/index/"&gt;&lt;/div&gt; // combo box store </code></pre> <p>//combo box</p> <pre><code>&lt;input dojoType="dijit.form.ComboBox" value="Select" width="auto" store="parentStore" searchAttr="name" name="parent" id="parent" onchange="displayChildren()"&gt; </code></pre> <p>//MY GRID</p> <pre><code>&lt;table dojoType="dojox.grid.DataGrid" jsId="grid" store="store" id="display_grid" query="{ child_id: '*' }" rowsPerPage="2" clientSort="true" singleClickEdit="false" style="width: 90%; height: 400px;" rowSelector="20px" selectionMode="multiple"&gt; &lt;thead&gt; &lt;tr&gt; &lt;th field="child_id" name="ID" width="auto" editable="false" hidden="true"&gt;Text&lt;/th&gt; &lt;th field="parent_id" name="Parent" width="auto" editable="false" hidden="true"&gt;Text&lt;/th&gt; &lt;th field="child_name" name="child" width="300px" editable="false"&gt;Text&lt;/th&gt; &lt;th field="created" name="Created Date" width="200px" editable="false" cellType='dojox.grid.cells.DateTextBox' datePattern='dd-MMM-yyyy'&gt;&lt;/th&gt; &lt;th field="last_updated" name="Updated Date" width="200px" editable="false" cellType='dojox.grid.cells.DateTextBox' datePattern='dd-MMM-yyyy'&gt;&lt;/th&gt; &lt;th field="child_id" name="Edit/Update" formatter="fmtEdit"&gt;&lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;/table&gt; </code></pre> <p>//onchange method of parent combo box in which i am trying to reload the grid with new data from the server.</p> <pre><code>function displayChildren() { var selected = dijit.byId("parent").attr("value"); var grid = dojo.byId('display_grid'); var Url = "/childsku/index/parent/" + selected; grid.setStore(new dojo.data.ItemFileReadStore({ url: Url })); } </code></pre> <p>But it's not updating my grid with new contents. I don't know how to refresh the grid every time users changes the combo box value. </p> <p><strong>I would be glad if I get the solution for both ItemFileReadStore and ItemFileWrireStore.</strong></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.
