I am using handler to display image from database in my web page.

I have given url of handler with passing category code for its image. But if no image found from db then I want to display no image in place of that handler url.

My code: I am using below image in my repeater control and want no image if no image found from db.

<img src="Webservice/AppServices.ashx?type=categoryimage&catid=<%# Eval("ProductCategorieId") %>" height="100" width="120" class="catimage" />

How can I check with that url and display no image?

Use onerror event like this:

<img src="MyHandler.ashx?id=myId" onerror="this.src='errorImage.png';" />

this.src should point to an existing image!

Yeah, It worked. Can you please elaborate about onerror behavior. You mean it will use noimage url if no image in url found in srs tag.
This is correct. Just don't write anything inside your handler when db image not exists.
This approach (instead of handling it in your ashx) also has the benefit of being more resilient to backend failures.
