Question

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?

Answer 1

Use onerror event like this:

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

this.src should point to an existing image!
