Passing parameter via quertystring

I want to pass 3 parameters to ashx file to handle the image, for that i used ImageUrl=ImageHandler.ashx?uid=1&iid=1&a开发者_StackOverflow社区mp;pid=1 but the image get not bound..

Help with correct syntax..

You may forget " for the code plus the correct location:

ImageUrl="~/ProjectLocationPathToTheImage/ImageHandler.ashx?uid=1&iid=1&pid=1"

If ImageUrl=ImageHandler.ashx?uid=1&iid=1&pid=1 is a part of your URL, then it appears that ImageUrl=ImageHandler.ashx is a query string parameter. If so, you need to change ?uid= to &uid=. What is the full URL that you are having issues with?
