I would like in the image tag area of the map in the href attribute instead of putting the page link I want it to receive a parameter that is sent to a C # method.
HTML code
<img src="../css/image/cores.png" alt="Escolha a cor que deseja" usemap="#Cores" onclick="ImageMap_Click"/>
<map name="Cores">
<area shape="rect" alt="Rosa" coords="8,8,96,116" href="<%#Eval("")%>">
