Ok then Rewrite your code as:

<b>

<%# Eval("Name") %></b></div>

<div>

$<%# Eval("id") %></div>

<asp:button ID="Button1" text="Buy" runat="server" commandname='<%# Eval("Name") %>' commandArgument='<%# Eval("Id") %>' OnClick ="Button1_Click" />

</asp:button>

and change in code behind also.


protected void Button1_Click(object sender, EventArgs e)

{

if (ListView1.Items.Count > 0)

{

string name = ((Button)sender).CommandName;

string id = ((Button)sender).CommandArgument;

MessageBox.Show("You click product " +);

}

}
