سلام
دوستان، اگر در دیتاگرید ویوی خودتون دو ستون داشته باشید که ستون صفرم، حاوی رشته های انگلیسی و ستون یکم، حاوی رشته های فارسی باشه، می تونید توسط این کد، رشته ای رو که کاربر در textbox مورد جستجو قرار می ده رو در دیتاگرید ویو رنگی کنید.
نکته ای که هست اینه که برای رشته های فارسی، محدودیتی وجود دارد، مثلاً:
ب خ ار در خروجی می آید
به جای
بخار
که ظاهراً در این محیط نمی شه حلش کرد چون پیچیده است.
