    <p>The code below works if you enter a city and state, then click outside of the text box but NOT directly on the Search submit button. Clicking outside of the text box triggers the onblur event which fires the javascript code to run a bing maps geocode on the city and state and populates the two hidden text boxes with the latitude and longitude. THEN when you click the submit button the code passes the latitude and longitude into the CityDistanceSort action on the Job controller which sorts the cities in the database based on their distance from the latitude and longitude passed in, then posts that sorted model to the view. Everything works except that you need to be able to enter the City and State and then of course just click the Submit button directly. But doing so doesn't give the JS code time to geocode and causes an error: The parameters dictionary contains a null entry for parameter 'SearchLatitude' of non-nullable type 'System.Double...</p> <pre><code>@using(Html.BeginForm("CityDistanceSort", "Job")) { &lt;input type="hidden" name="SearchLatitude" id="SearchLatitude"&gt; &lt;input type="hidden" name="SearchLongitude" id="SearchLongitude"&gt; &lt;input type="text" name="CityStateName" id="CityStateName" placeholder="CITY, BY DISTANCE" onblur="GeocodeSearchCityState()"&gt; &lt;input type="submit" value="SEARCH" /&gt; } </code></pre> <hr> <pre><code> [HttpPost] public ActionResult CityDistanceSort(double SearchLatitude, double SearchLongitude) { var model = db.Jobs.ToList(); foreach (var item in model) { item.PickupDistanceSort = ICN.CustomMethods.GetDistance(SearchLatitude, SearchLongitude, item.PickupLatitude, item.PickupLongitude); } return View("JobHeadings", model.OrderBy(s =&gt; s.PickupDistanceSort)); } </code></pre>

    2. COHow do you call the function before the form is submitted without the user having to click two buttons? One to call the calculation, and one to submit the form. Plus, the calculation is being called before the form is submitted with the onblur event, but that is not working.

    3. COone way to achieve this is, make your submit button a normal button then on click of button call the calculate code and then submit the form from jquey code `$("form#formID").submit();`

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).
