1. استفاده از EF به عنوان منبع داده و ارسال آن‌ها به سمت گزارش ساز
2. نحوه طراحی فایل MRT و بایند کردن داده‌های اطلاعاتی و ایجاد جدول
3. استفاده از امکانات فایل خروجی ، چاپ و پیش نمایش و...
4. بررسی Direction جهت استفاده در محیط‌های فارسی زبان
5. نحوه ارسال اطلاعات بین دو اکشن متفاوت

طراحی فایل MRT

فایل MRT در واقع یک قالب (Template) خالی از مقادیر متغیر است که در StimulSoft Studio به طراحی آن میپردازیم و در برنامه خود، این مقادیر متغیر را با اطلاعات دلخواه خود جایگزین می‌کنیم. تصویر زیر یک نمونه از یک گزارش خالی است که ابتدا آن را طراحی کرده و سپس در برنامه آن را مورد استفاده قرار می‌دهیم:

برای اینکه فایل MRT بتواند دیتاهای لازمی را که به آن پاس میدهیم، بخواند و در جای مشخص شده قرار بدهد، باید یک BussinessObject برای آن ایجاد کنیم. بعد از اینکه یک گزارش جدید ایجاد کردید، در سمت راست به قسمت Dictionary بروید و در قسمت BussinessObject گزینه NewBussinessObject را انتخاب کنید. یک نام و نام مستعار که عموما هم یکی است، برای آن انتخاب کنید. در زیر همان پنجره شما می‌توانید ستون‌های اطلاعاتی خود را تعریف کنید. در اینجا من میخواهم اطلاعات یک راننده را به همراه خودروی وی، نشان دهم. برای همین، من دو موجودیت راننده و خودروی راننده را دارم. پس اسم Business Object را DriverReport میگذارم و ستون‌های اطلاعاتی فقط راننده (بدون در نظر گرفتن خودروی وی) را وارد میکنم.

در همین کادر بالا شما میتوانید تصیم بگیرید که آیا میخواهید اطلاعات خودرو را به همراه دیگرستون‌های اطلاعاتی راننده، ایجاد کنید یا اینکه برای خودرو یک نوع مجزا انتخاب کنید. اگر تنها یک خودرو برای راننده باشد، شاید راحت‌تر باشید همانند اطلاعات راننده با آن رفتار کنید. ولی اگر مثلا بخواهید خودروی‌های گذشته راننده را هم جز لیست داشته باشید، بهتر است یک  Business Object جدید متعلق و زیر مجموعه Business Object راننده ایجاد کنید. در اینجا چون تنها یک خودرو است، من آن اطلاعات آن را به همراه راننده، ارسال میکنم. شکل زیر ساختار درختی از گزارش بالاست:

شکل زیر هم یک ساختار دیگر از یک گزارش است که شامل Business object‌های مختلف می‌شود: 

سپس همین فیلدها را به سمت صفحه خالی بکشانید. با دو بار کلیک روی فیلدهای قرار گرفته در صفحه، با نحوه بایند کردن مقادیر آشنا می‌شوید؛ هر فیلدی که قرار است دیتای آن بایند شود، باید به شکل زیر در بخش Expression پنجره باز شده، نوشته شود:

{driverReport.LastName}

راه اندازی گزارش ساز در ASP.Net MVC

اولین کاری که می‌کنیم، ورود سه dll اصلی به پروژه است:

Stimulate.Base

Stimulate.Report

Stimulate.Report.MVC

در مرحله بعد یک متد ساخته و یک ویوو را برای صفحه گزارش گیری ایجاد می‌کنیم:
