Have you checked the generated url in the html code?

Thanks for reply.

Ya i am check my html code but my app key didn't render and not show the given app key url.
my html rendered code is
<input type="image" src="<%$%20AppSettings:PagePath%20%>_Images/btn-edit.jpg" id="MainContent_imgUpdate" name="ctl00$MainContent$imgUpdate">

And what is your AppSettings section? Shouldn't that be appSettings instead (lower case "a")?

In web config my app setting section is above mentioned

I am not sure about the case sensivity here, but try: <%$appSettings:PagePath %>
But I don't know why you are using this, is the images folder on an other server instance? If not, simply use ImageUrl='/_Images/btn-edit.jpg'

ya when i am use in normal without any control binding it will work properly,
Means when i am use '<%$ AppSettings:PagePath %>' only this in my page my app key display in my rendered page but when i am use in control with my image name it is not work.

ImageUrl='/_Images/btn-edit.jpg' -> This solution work proper but i m use url rewriting and use a Trailing Slash in url it is not work. mens does not show my image.

Can u please any another suggestion provide me , I am awaiting it.
Thanks

Solution 1

Use

ImageUrl='<%# ConfigurationManager.AppSettings["PagePath"] +"_Images/btn-edit.jpg" %>'

But now you need to call Page.DataBind in page load. If container of the control is another control other than Page then DataBind needs to be called for container control.
