    <p>First of all I can mention, that I am a little pessimistic about implementation of custom searching dialog. The reason is that you will invest much time in the implementation. I would you better recommend to use custom controls inside of <em>standard</em> searching dialog. After applying <a href="https://github.com/tonytomov/jqGrid/commit/03d31332cf62c6f819a7fc0fcb99d50dd3f8f802" rel="nofollow noreferrer">the changes</a> which I suggested it is now possible.</p> <p>Look at <a href="http://www.ok-soft-gmbh.com/jqGrid/Ranking2.htm" rel="nofollow noreferrer">the demo</a> which allows you to create searching dialog like</p> <p><img src="https://i.stack.imgur.com/8jDE6.png" alt="enter image description here"></p> <p>In the way you can solve many problems which you described in your question.</p> <p>If you do decide to create custom searching dialog you will have to do the following:</p> <ul> <li>The new searching dialog should add information about the searching criteria in <code>postData</code> properties.</li> <li>reload the grid using <code>.trigger.("reloadGrid")</code></li> </ul> <p>You don't need make separate Ajax request to the server. Reloading of the grid is what you need to do.</p> <p>If you want to save the information about the filter in the <code>postData.filters</code> you have to hold <a href="http://www.trirand.com/jqgridwiki/doku.php?id=wiki:advanced_searching#options" rel="nofollow noreferrer">the standard format</a>. In the case you can have advantage of local data filtering (<code>datatype: 'local'</code> or the usage of <code>loadonce: true</code>). See the demo from <a href="https://stackoverflow.com/a/3979490/315935">the answer</a> as an example.</p> <p>If you want to implement filtering of data on the <em>server side</em> only you can use any format of additional properties (please don't use the same name <code>filters</code>). If you want to have searching filter (controls) always visible on the page I would recommend you to use the technique with <code>postData</code> properties as function (see <a href="https://stackoverflow.com/a/2928819/315935">the answer</a>).</p>

    1. COare you saying that adding the search info obtained from the customized search dialog to `postData` and then `reloadGrid` will preserve any future `next` and `previous` paging?

    2. COI am not sure that I understand what you mean. What you mean with "next" and "previous" paging? Could you specify which values of `datatype` and `loadonce` you want to support? What is your standard situation: local searching or searching on the server? Any information from `postData` will be send to the server, but not all will be interpreted on local filtering.

    3. COsorry if wasn't clear. The "next" and "previous" paging is what I mean when the user tries to view other pages in the grid which are populated with the searched data obtained from the server as `JSON`. In this case the grid is set with `loadonce = false` and `datatype = 'json'`. I am not trying to implement paging on the local data fetched from the searched result, but rather on the server side, I am just thinking for the future in case the obtained searched data is too huge be cached locally.

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.
