    <pre><code>private void DisplayImages(string imageFile) { Image pImage = new Image(); pImage.ImageUrl = imageFile; this.Controls.Add(pImage); } </code></pre> <p>above is the current code but the image is not getting displayed and I want to check URL value. I have a javascript function that will check for URL and return the URL. All I need to do is assign the URL returned from javascript to the above image using what is called as POST. How can I achieve this in code-behind in above function?</p> <p>Please suggest.</p> <p>Update 1: I had forgot to add "this.Controls.Add(pImage);". I have added above.</p> <p>Update 2: I am creating Image control (As shown in the code) during onLoad of the page. The URL for this is usually longer and comes from an XML. I printed the URL value before assigning to image control.</p> <p>Now for some reason, image doesn't render in browser. Just now I found that even that URL when rendered in separate browser gives me HTTP 403. The person who built that URL and stored in XML tells me that I should use Javascript and do a POST by sending this URL. I need to know how I can do the javascript in the below code such that the image URL gets assigned after the POST method. Hope this clarifies.</p> <p><strong>Update 3</strong>: Below is the Javascript in the ASPX page.</p> <pre><code> &lt;script type="text/javascript"&gt; // Open URL in new window with a a post instead of the get function posturl(url) { alert("I am here"); var qsBegin = url.indexOf("?"); var qsPattern = new RegExp("[?&amp;]([^=]*)=([^&amp;]*)", "ig"); var match = qsPattern.exec(url); var params = new Array(); while (match != null) { // matched text: match[0] // match start: match.index // capturing group n: match[n] var matchID = match[1]; if ( matchID.charAt(0) == "&amp;" ) { matchID = matchID.substr(1); } if ( params[match[1]] != null &amp;&amp; !(params[match[1]] instanceof Array) ) { var subArray = new Array(); subArray.push(params[match[1]]); subArray.push(unescape(match[2])); params[match[1]] = subArray; } else if ( params[match[1]] != null &amp;&amp; params[match[1]] instanceof Array ) { params[match[1]].push(unescape(match[2])); } else { params[match[1]]=unescape(match[2]); } match = qsPattern.exec(url); } var myForm = document.createElement("form"); //myForm.setAttribute("target", "_blank"); myForm.method="post" ; myForm.action = url.substring(0,qsBegin) ; for (var k in params) { var myInput; // Check for params with the same name. if ( params[k] instanceof Array ) { for ( var i=0; i&lt;params[k].length; i++ ) { myInput = createFormInput(k, params[k][i]); myForm.appendChild(myInput) ; } } else { myInput = createFormInput(k, params[k]); myForm.appendChild(myInput); } } document.body.appendChild(myForm) ; myForm.submit() ; document.body.removeChild(myForm) ; //return "did you get what you wanted"; } &lt;/script&gt; </code></pre>

    2. COYou already asked this question. Please do not post duplicates. [Need to display image in ASPX page that has long url](http://stackoverflow.com/questions/10709044/need-to-display-image-in-aspx-page-that-has-long-url) For the record: "POST" *can not* be used here; HTML `img` tags will *only* make their requests via `get`. You can't alter that. You should *never* have to.

    3. CO@AndrewBarber:Thanks for the update and sorry for double post but I wanted to ask here with question specific to POST. So what are the changes I need to make in order to work with POST. I have been told that's the only hope to get the imageUrl displayed. Sorry again.

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.

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