Binding expressions can't start from the middle of an attribute value. You need to write it like that:

<asp:TextBox onkeyup='<%# "LoadAttributeValueLong(" + Eval("ID") + ")" %>'

To pass also the value of the tbxId textbox:

<asp:TextBox onkeyup='<%# "LoadAttributeValueLong(" + Eval("ID") + ",\"" + tbxId.ClientID + "\")" %>'

And in your js function:

LoadAttributeValueLong(id, tbxId)
{
   var tbxIdValue = $('#' + tbxId).val(); // jquery version
   var tbxIdValue = document.getElementById(tbxId).value; // non jquery version
}
