I've found a way to do what I wanted. I use jqGrid in several places (including multiple grids on the same page in a few cases), so I factored it out into a function I can call from anywhere and which contains its own scope for managing whether there is a current request; just pass it a grid and it will attach all of the necessary event handlers. Note that this will overwrite any existing handlers you may have defined for the relevant events. <pre><code>function applyJqgridHandlers(grid) { (function(self, undefined) { var currentRequest; function abortCurrentRequestIfAny() { if (currentRequest !== undefined) { currentRequest.abort(); } } self.clearCurrentRequest = function() { abortCurrentRequestIfAny(); currentRequest = undefined; }; self.setCurrentRequest = function(xhr) { abortCurrentRequestIfAny(); currentRequest = xhr; }; })(grid.currentRequestHolder = {}); grid.currentRequestHolder.clearCurrentRequest(); grid.jqGrid('setGridParam', { loadError: function(xhr, status, error) { grid.currentRequestHolder.clearCurrentRequest(); }, loadBeforeSend: function(xhr, settings) { grid.currentRequestHolder.setCurrentRequest(xhr); }, loadComplete: function(data) { grid.currentRequestHolder.clearCurrentRequest(); } }); grid.bind('jqGridToolbarBeforeSearch', function() { grid.currentRequestHolder.clearCurrentRequest(); this.grid.hDiv.loading = false; }); }; </code></pre> Then I simply add a call to this function from the end of setupGrid(). This code explicitly clears the ts.grid.hDiv.loading flag, which is not part of the published jqGrid API, so I consider this solution to be fairly fragile; there's no guarantee that it would continue to work for future versions of jqGrid. If anyone has any suggestions for better (less fragile) ways to solve this problem, I'm all ears. :)

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.
