You can better do it in javascript. Get the offsetHeight of datagrid in javascript and set the height of other panel as below.

var height = document.getElementById("<%=GRIDID_CONTROL.ClientID%>").offSetHeight;
document.getElementById("<%=PANEL_CONTROL.ClientID%>").style.height = height;

Write this script at the end of page, so that you have markup rendered for the controls.
