Couple of issues with your code.

1) No OnClick Property set.

2) Remove that extra true; in your onclientclick. You are already returning true from your returnTrue() function. Change your code as below.

ASP.NET

<asp:linkbutton id="cancel" runat="server" onclientclick="return returnTrue();" onclick="cancel_Click" >

3) If you noticed above I have assigned cancel_Click event to OnClick, then it should be defined in your code-behind.

C#

void cancel_Click(object sender, System.EventArgs e)
{
  //Your Button Clcik code here.

}
