Watermark for an ASP.Net Panel

Question

Does an asp.net panel can be inserted with a watermark? These panel is used for printing purposes. Another problem is that the background image in the panel is not printing, only the objects inside of it.

Answer 1

I think you should take a look at BackImageUrl property. And assign the path of the watermark image to it.

<asp:Panel BackImageUrl="yourimagefile.png" />

Also, the image should be given a proper opacity / alpha value so that it's transparent.

Answer 2

这是来自codeproject的另一个示例http://www.codeproject.com/KB/web-image/ASPImaging1.aspx ，您可以对图像进行很多思考，包括从图像中添加水印。

Answer 3

<asp:Panel ID="Panel1" runat="server">

<asp:Image ID="Image1" runat="server" ImageUrl="~/yourimage.png" />

<div style="margin-top: -xxx"><--change the position <div> to overlaps with the image
