    <p>I have a jqGrid that when I go into edit mode I need to have 2 select lists. I need the second list to filter based on the selection from select list 1.</p> <p>This is my first attempt at working with jqGrid so I am having some troubles with things.</p> <p>I have seen a few examples that are using hard coded arrays etc., but I need to pull the information from a database and I am having trouble getting it to work.</p> <p>I guess I need to have my hand held through this one. :-p</p> <p>My columns in question are the AssemblyTypeName and the AssemblyName, I need to fill them in that order.</p> <p>My jqGrid code is below:</p> <pre><code> $("#jqTable").jqGrid({ // Ajax related configurations url: '@Url.Action("_CustomBinding")', datatype: "json", mtype: "POST", postData: { programID: function () { return $("#ProgramID option:selected").val(); }, buildID: function () { return $('#Builds option:selected').val(); } }, // Specify the column names colNames: ["Actions", "Assembly ID", "Assembly Type", "Assembly Name", "Cost", "Order", "Budget Report", "Partner Request", "Display"], // Configure the columns colModel: [ { name: 'myac', width: 80, fixed: true, sortable: false, resize: false, formatter: 'actions', formatoptions: { keys: true} }, { name: "AssemblyID", key: true, index: "AssemblyID", width: 40, align: "left", editable: false }, { name: "AssemblyTypeName", index: "AssemblyTypeName", width: 100, align: "left", editable: true, edittype: 'select', editoptions: { dataUrl: '@Url.Action("_AssemblyTypes")', buildSelect: function (data) { var response = jQuery.parseJSON(data); var s = '&lt;select&gt;'; if (response &amp;&amp; response.length) { for (var i = 0, l = response.length; i &lt; l; i++) { var ri = response[i]; s += '&lt;option value="' + ri + '"&gt;' + ri + '&lt;/option&gt;'; } } return s + "&lt;/select&gt;"; } } }, { name: "AssemblyName", index: "AssemblyName", width: 100, align: "left", editable: true, edittype: 'select', editoptions: { dataUrl: '@Url.Action("_Assemblies")', buildSelect: function (data) { var response = jQuery.parseJSON(data); var s = '&lt;select&gt;'; if (response &amp;&amp; response.length) { for (var i = 0, l = response.length; i &lt; l; i++) { var ri = response[i]; s += '&lt;option value="' + ri + '"&gt;' + ri + '&lt;/option&gt;'; } } return s + "&lt;/select&gt;"; } } }, { name: "AssemblyCost", index: "AssemblyCost", width: 50, align: "left", formatter: "currency", editable: true }, { name: "AssemblyOrder", index: "AssemblyOrder", width: 50, align: "left", editable: true }, { name: "AddToBudgetReport", index: "AddToBudgetReport", width: 100, align: "center", formatter: "checkbox", editable: true, edittype: 'checkbox' }, { name: "AddToPartnerRequest", index: "AddToPartnerRequest", width: 100, align: "center", formatter: "checkbox", editable: true, edittype: 'checkbox' }, { name: "Show", index: "Show", width: 50, align: "center", formatter: "checkbox", editable: true, edittype: 'checkbox'}], // Grid total width and height and formatting //width: 650, //height: 220, altrows: true, // Paging //toppager: true, pager: $("#jqTablePager"), rowNum: 10, rowList: [10, 20, 30], viewrecords: true, // Specify if "total number of records" is displayed emptyrecords: 'No records to display', // Default sorting sortname: "AssemblyID", sortorder: "asc", // Grid caption caption: "Build Template", // grid command functionality editurl: '@Url.Action("_AjaxUpdate")', onSelectRow: function (AssemblyID) { if (AssemblyID &amp;&amp; AssemblyID !== lastsel) { $('#jqTable').jqGrid('restoreRow', lastsel); var cm = $("#jqTable").jqGrid('getColProp', 'AssemblyTypeName'); cm.editable = false; $("#jqTable").jqGrid('editRow', AssemblyID, true); cm.editable = true; lastsel = AssemblyID; } } }).navGrid("#jqTablePager", { refresh: false, add: true, edit: false, del: false }, {}, // settings for edit {}, // settings for add {}, // settings for delete {sopt: ["cn"]} // Search options.

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.

SQuiL has stopped working due to an internal error.

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