Merhaba,

Teşekkürler, @"Fesih ARSLAN", @klavye İlerde yapacaklarımı GitHub üzerinden eklemelere devam edeceğim. Aslında Github üzerinde başka yayınladığım kodlarda mevcut. Özellikle Edit için bileşen var. Çok güzel en azından benim için çok kullanışlı.

ThsStringGrid için sonraki adımda ihtiyaca göre Column Sort, Grid için Find Text and Highlight ekleyeceğim. Belki alt toplam(Sum), Fixed Col ile Satır numaraları otomatik çıkması(Excel gibi) olabilir.
Bu arada boyama öncelikleri resimde görülüyor fakat özellikle buradan da belirteyim.
Column -> Row -> Cell
Ayrıca stringgrid drawcell özelliği ile de bu yaptığınız boyama stilerrini ezerek özel boyama da yapabiliyorsunuz.

Class Helper olarak düzenledim.
Kullanımı: Aşağıdaki uniti projenize dahil etmeniz yeterli. Kullanmak istediğiniz (TStringGrid kullandığınız) form içine uses kısmına Ths.Erp.Helper.StringGrid uniti tanımlayın. Hepsi bu kadar.

Mevcut komponent kodunda bazı hatalarla karşılaştım. Bu hatalar düzeltildi ayrıca iyileştirme yapıldı. Ayrıca sıralama(Sort) özelliği eklendi. Şu anda sadece string olarak sıralama yapıyor. Asc ve Desc olarak çalışıyor. Şu anda 1 Fixed Row(Başlık için) olacak ve üzerine tıklama yapılan kolon için sıralama yapılyor. ilk tıklamada Asc aynı sütuna tekrar tıklama durumunda Desc olacak şekilde sıralama yapıyor.

Mevcut bir TStringGrid içeriğini DevExpress Excel bileşenini kullanarak bir Excel dosyaya kaydetmek için aşağıdaki kodu kullanabilirsiniz.

@uparlayan hocam daha önce özellik listesine eklemiş olduğunuz koşullu renklendirme kodunu ekledim.
Fixed Row ve Fixed Col için arkaplan rengi ve font özellikleri eklendi.
Fixed Col içinde arkaplan rengi ve font özellikleri eklendi.
Ayrıca hangi satırma olduğunu bildirmek amacıyla fixed col(satır numaralarının olduğu) sütununda aktif satır rengi eklendi.

   
iyileştirme yapıldı.

Koşullu biçimlendirme için şu anda en az bir tane style tanımlı olmalı. Sütun Satır veya hücre için. Daha sonra bu style için koşul yazılıyor.

Ayrıca sort algoritması çok kullanışlı olmadı. Satır sayısı 100000 gibi olunca bayağı yavaş kalıyor. Orada düzeltme iyileştirme şart. Fakat bayağı kullanışlı oldu. Ayrıca sıralama yapılınca yön oku da ekleyeceğim. Sonrasında highlighter

Sort için hızlandırma yapıldı
Sıralamayı göstermek için fixed row(başlık) rowa küçük oklar eklendi.
Yatay hizalama vardı. Dikey hizalama eklendi. Style özelliğine göre hücre içinde bilgi dikey olarak yukarı aşağı orta ve yata olarak sağ, sol, orta olarak hizalanarak çıkartılıyor.
