Önceki yıllarda çekmiş olduğum 5 bölümlük bu seri ile; User Control oluşturma, oluşturulan user controlleri projemizde kullanma, user controllerden XML oluşturma ve XML ile çalışma hakkında sizi tecrübe sahibi yapacak bir User Control ve XML örnek projesi video serisidir.
Bu yazımızda yanıp sönen ve kullanıcının ilgilini çeken bir etiket(Label) kontrolü geliştireceğiz. Projelerimde çoğu zaman böyle bir ifadeye, kullanıcının mutlaka okuması gereken, dikkat etmesi gereken yazılara ihtiyaç duyarım. Çoğu uygulamada da bu şekilde ifadeler mevcuttur. Yaygın olarak bu ifadeler uygulama içinde “Kalın(Bold)” ve “Altı Çizili(Underline)” olarak ayarlanırlar. Ya da kırmızı olarak renklendirilirler. Fakat yaptığım projelerde karşılaştığım kadarı ile bu belirginleştirme, kullanıcıların farketmesini sağlamıyor. Ya da kullanıcıların alışkanlıklarından ötürü dikkatlerinin oraya çekilmesini sağlamıyor. Bu konuda düşünürken, bu konuda parlak bir fikir aklıma geldi. 🙂 Evettt gerçekten parlak, hatta yanıp sönen :)) Sonunda yanıp sönen bir etiket(Label) kontrolü geliştirmeye karar verdim. Sonunda nasıl birşey mi çıktı. Buyrun aşağıdadır.

RadGridView kontrolünü kullanarak birçok işlemi yapabiliyoruz.. Bu işlemler;
Excel Export.. Kolon başlığı verme, kolon tipi verme, kolon boyutu, hizalama.. Kayıt Sayısı bilgisi.. Alternatif row ayarı, gruplama..
gibi işlemleri daha pratik yapabileceğim bir user control geliştirdim. Aşağıda bu kontrol ile ilgili bilgileri ve kodları bulabilir sizde kullanabilirsiniz..
Tabii bu kontrolü oluşturmak için Telerik firmasına ait WinControls setine sahip olmanız gerekmektedir.. İlgili referansları eklemeyi unutmayınız..

Bu görsel derste;
Bir Container(Panel) içine kendi oluşturduğumuz UserControllerin Run-time ‘da dinamik olarak eklenmesini, ardından bir tıklama ile container içine eklediğimiz UserControllerin XML bir dosyaya kayedilmesini sağlayacağız. Ardından bu dosyadan okuyarak UserControlleri container içine tekrardan oluşturacağız.. Son olarak’da container içinde inşaa ettiğimiz UserControllerimizin container dışındaki bir kontrole nasıl erişbileceğini göstereceğim.
Tüm bu işlemleri yaparken, form arka planına kod yazımını en az düzeyde tutup, UserController ve container(Panel) içinde metod tanımlayarak bu kısımlarda kodu oluşturacağız. Böylece daha sade ve temiz bir kodlama ile modüler bir yapı oluşturmuş olacağız. Bu yapı sayesinde istediğimiz zaman projeye Usercontrol ekleyerek projenin daha temiz ve karmaşıklaşmadan genişlemesini sağlayacağız. Ayrıca modifikasyona açık bir yapı oluşturmuş olacağız.
3 bölüm şeklinde yayınlayacağım bu konuyu severek izleyeceğinizi umuyorum.. 🙂
3. bölümden sonraki makalemde pojenin kodunu bulabilirsiniz. Ayrıca projeyide indirebilirsiniz..
User Control To Xml görsel dersimizin 2. bölümünde;
Oluşturduğumuz user controlleri XML olarak kaydetmek ve XML’den okuyarak tekrar listelenmesini sağlıyor olacağız.. 1 saatlik bir video olduğu için 3 parça olarak yayınlıyorum . 🙂

UserControl To Xml Bölüm 3 görsel dersinde;
Run-time’da oluşturduğumuz UserControl’lerimizin içinde bulundukları Container Panel dışında bir kontrole erişimlerini nasıl sağladığımızı görebilirsiniz.. Mümkün oldukça Form.cs class’ına kodlama yapmadan erişim sağlamanın yöntemini geliştiriyoruz..
