    <p>I was trying to return Json from my action and after that IE tried to download it and showed me save dialog. I tested it in Firefox, and there it works fine.</p> <pre><code>return Json(new { success = false, message = ex.Message }, "application/json"); </code></pre> <p>What is the reason of that behavior and how can I solve that issue?</p> <p>After that in Javascript part I try this</p> <pre><code> if (responseJSON.success == false) { alert(responseJSON.message); cancel(); } </code></pre> <p>But IE doesn't show alert anyway. It brings me save dialog.</p> <p>I tried to change <code>"application/json"</code> with <code>"text/plain"</code> and save dialog disappeared, but I am not able to see alert yet. What am I missing?</p> <p><strong>EDIT:</strong></p> <p>Here is my complect Javascript, I am using Valums qquploader(ex-Ajaxupload) for uploading images</p> <pre><code> var uploader = new qq.FileUploader({ element: document.getElementById("image-upload"), action: '/Home/ImageUpload', allowedExtensions: ['jpg', 'png', 'gif'], sizeLimlit: 2048,onComplete: function (id, fileName, responseJSON) { if (responseJSON.success == false) { alert(responseJSON.message); cancel(); } else { alert("success"); //some code here } } }); </code></pre> <p>I had tested with <code>alert("success");</code> in my else part and forwarded json as <code>"text/plain"</code> and after that I saw the alert. But in that time <code>responseJSON.success != false</code> for me. Have you any suggestions about that?</p>

Guidance
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).
