I want an animated gif image to be shown once the form is submitted and some time-consuming activities is run in the server side.
Now, upon clicking on the button, the hidden image is shown. However, surprisingly, the animated gif becomes a still one while the backend time-consuming activity is in progress. The image is not animated any more.
In the code file behind. I wrote:
private void Page_Load(object sender, System.EventArgs e)
{
Button1.Attributes.Add("onclick","showImage();");
}
public Button1_click(....)
{
time consuming operation here...
}
then one the .aspx file, I wrote the script as:
function showImage()
{
document.getElementById(imageID).style.visibility = "visible";
}
How come the image is not animated any more while the time-consuming function is running behind??
