Try this,

string strJS = @" intWidth = document.body.clientWidth;intHeight = document.body.clientHeight;intWidth = (intWidth* 15/100);document.getElementById('<% =HpnlCtrlLeftPos.ClientID %>').value=intWidth; alert('Width : '+ intWidth +' Height : ' + intHeight); ";

Page.ClientScript.RegisterStartupScript(this.GetType(), "ScreenPosition", strJS, true);

if this doesn't help, post the error message you getting.
