Sort out your double quotes:

C#

string script = "<script language="\""javascript\"

Becomes

C#

string script = "<script language=\"javascript\"

modify as

C#

string strMsg = "Leave has been applied already between " + txtFromDate.Text.Trim() + " and " + txtToDate.Text.Trim() + "";
                     string script = "<script language=\"javascript\" type=\"text/javascript\">alert('" + strMsg + "');</script>";
                     Response.Write(script);

Note: Try to show alert message from javascript without postback

As OriginalGriff suggested you have missed out the string formatting. Below is working.

C#

txtFromDate.Text = DateTime.Now.AddDays(-2).ToString("MM/dd/yyyy");
            txtToDate.Text = DateTime.Now.AddDays(2).ToString("MM/dd/yyyy");
            string strMsg = "Leave has been applied already between " + txtFromDate.Text.Trim() + " and " + txtToDate.Text.Trim() + "";
            string script = "<script language=\"javascript\" type=\"text/javascript\">alert('" + strMsg + "');</script>";
            Response.Write(script);
