<div class="col-md-12 col-sm-12 col-xs-12">
     <asp:Literal ID="ltEmbed" runat="server"/>
</div>

        public void SetTrace_PDF()
        {
            try
            {
                //   Split AssessmentYear (2017-2018) to--> (2017-18);
                var EmpAssesmentYear = drpYear.SelectedValue;
                var FirstYear = AssessmentYear.ToString().Substring(0, 5);
                var SecondYear = AssessmentYear.ToString().Substring(7, 2);
                
                AssessmentYear = FirstYear + SecondYear;
                FY_Year = drpYear.SelectedItem.Text.TrimEnd(' ');

                string FilePath = "~\\Traces\\" + FY_Year + "/" + PanNumber + "_" + AssessmentYear + ".pdf";
                ltEmbed.Text = string.Format("<object data=\"{0}\" type=\"application/pdf\" width=\"1000px\" height=\"500px\"></object>", ResolveClientUrl(FilePath));
            }
            catch (Exception ex)
            {

            }
        }

I want to show message if the file is not present in given path i.e in the code

string FilePath = "~\\Traces\\" + FY_Year + "/" + PanNumber + "_" + AssessmentYear + ".pdf";

Refer the below code. You have to use Server.MapPath to get the proper file path.

protected void Page_Load(object sender, EventArgs e)
{
    SetTrace_PDF();
}

public void SetTrace_PDF()
{
    try
    {
        string FilePath = Server.MapPath("~\\Smaple.pdf");

        if (!System.IO.File.Exists(FilePath))
        {
            ClientScript.RegisterClientScriptBlock(this.GetType(), "", "alert('File does not exist.')", true);
        }
        else
        {
            ltEmbed.Text = string.Format("<object data=\"{0}\" type=\"application/pdf\" width=\"1000px\" height=\"500px\"></object>", ResolveClientUrl(FilePath));
        }
    }
    catch (Exception ex)
    {

    }
}
