public JsonResult CheckExist(string BranchCode)
{
    bool exists = _db.Branch.Any(x => x.iBranchCode == BranchCode);

    return Json(new { result = exists }, JsonRequestBehavior.AllowGet);
}

public JsonResult CheckExist(string BranchCode)
{
    bool branchExists = _db.Branch.Any(x => x.iBranchCode == BranchCode);

    // Create an anonymous object with the 'exists' property
    var result = new { exists = branchExists };

    // Return the result as JSON
    return Json(result);
}

Hi ahmad

try this code

public JsonResult CheckExist(string BranchCode)
{
    bool isExists = _db.Branch.Any(x => x.iBranchCode == BranchCode);
    return Json(new { result = isExists }, JsonRequestBehavior.AllowGet);
}
