I have a Image, FileUpload and a Button controls. I want to save the image to the server from the local path obtained from FileUpload control. I implemented this functionality on Button Click in C#..

Now i want to set the image URL of Image control OnClientClick of the same button on which server side code is implemented.

Image URL will defer everytime depending on file selected in FileUpload control. Can anyone help me to understand how javascript can be used to set image URL based on thre file selected in File Upload Control?

    First of all, understand that JavaScript doesn’t understand, care, or even know about C# and its fancy “controls”. It just deals with HTML. Period. That said, you can use JavaScript’s setAttribute function to set the image URL of an img tag (not control). Like this:

    document.getElementById('my-image').setAttribute('src', 'http://ecx.images-amazon.com/images/I/41%2BjAZ4dUGL._SS500_.jpg');
