Hi,

I want to call a c# function in Html tag. I wrote the following code, but it throws error.

ASP.NET

 <script language="C#" runat="server">
        public void create_Session_For_ProductID(string id)
        {
            if (Session["Sess_PID"] != "")
            {
                Session["Sess_PID"] = Session["Sess_PID"] + id;
            }
            else
            {
                Session["Sess_PID"] = id;
            }

        }
    </script>

<%
        
         functions func=new functions();
         foreach (var item in func.GetProductList())
           { %>
          <div id="i<%:item.ProductID %>" class="item">
              <%--<img src="%3C%:%20Url.Content%28" />"/>--%>
              <img src="<%:item.ProductImage %>" width="140px" height="160px"/>
              <label class="title">IMG <%:item.ProductID%></label>
              <label class="price">Rs. <%:item.Price %></label>  
                         
               
              <a id="aref" href="MyCart.aspx"  runat="server"  önserverclick="create_Session_For_ProductID(<%:item.ProductID %>)"><span>Add To Cart</span></a>       
          </div>          
         <% } %>

Without seeing any details of your error, I can only assume that it's the server side method signature that's the problem. Server side events have a different signature, for example:

C#

protected void Something_Click(object ssnder, EventArgs e){
    //your code here
}

And you'd call it like this:
