This is the logic. Insert is working fine for all other fields. BUt Imagepath is taking null.

if (btn_add.Text == "Submit")
        {
           
               
                

                BracketAccessoriesEntity.BracketSuspensionType = Convert.ToString(txt_BracketSuspensionType.Text.Trim());
                BracketAccessoriesEntity.PoleTypeID = Convert.ToInt64(dd_PoleTypeID.SelectedValue.Trim());
                BracketAccessoriesEntity.AccessoryID = Convert.ToInt32(ViewState["Id"]);
                BracketAccessoriesEntity.Status = chk_Active.Checked;
                System.Collections.Hashtable ht = (System.Collections.Hashtable)Session["UserDetails"];
                Int64 UsrId = (Int64)ht["UserID"];
                BracketAccessoriesEntity.UpdatedBy = UsrId;
                BracketAccessoriesEntity.UpdatedOn = (DateTime.Now);
                string filename = Path.GetFileName(fileuploadimages.PostedFile.FileName);
                fileuploadimages.SaveAs(Server.MapPath("~/Images/Bracket Type/" + filename));
                BracketAccessoriesEntity.ImagePath = "~/Images/Bracket Type/" + filename;

                try
                {
                    string result = logic.InsertData(BracketAccessoriesEntity);
                    if (result == "SUCCESS")
                    {
                        string jScript = "<script>alert ('" + "Record Updated Successfully" + "')</script>";
                        ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "starScript", jScript, false);
                        clear();
                       
                        BindGrid();
                    }

I know I am making mistake with Image path. Can you please suggest what should I write in these lines because maybe mistake is here.

string filename = Path.GetFileName(fileuploadimages.PostedFile.FileName);
fileuploadimages.SaveAs(Server.MapPath("~/Images/Bracket Type/" + filename));
BracketAccessoriesEntity.ImagePath = "~/Images/Bracket Type/" + filename;
