สอบถามปัญหา Error RowDataBound ของ Gridview ครับ ภาษา ASP.NET C# ครับ
เนื่องจากได้ศึกษาจากหัวข้อhttps://www.thaicreate.com/asp.net/c-sharp-asp.net-gridview-control-databound.html Quote: Compiler Error Message: CS1061: 'ASP.sai_aspx' does not contain a definition for 'myGridView_RowDataBound' and no extension method 'myGridView_RowDataBound' accepting a first argument of type 'ASP.sai_aspx' could be found (are you missing a using directive or an assembly reference?)

ดูผิวเผินยังไม่ได้เอาไปลอง Run นะครับ สังเกตเห็นว่าปีกกาหายไป 1 บรรทัด ที่บรรทัด 101 ไม่มี } เพื่อปิด void myGridView_RowDataBound ใช่หรือไม่ ลองตรวจสอบดู เพราะ Error เป็น Compiler Error ไม่ใช่ Runtime Error นะครับ

สังเกตดี ๆ นะครับที่ Code Behind การประกาศ Method Code (C#) void myGridView_RowDataBound(Object s, GridViewRowEventArgs e)
Code (C#) protected void myGridView_RowDataBound(Object s, GridViewRowEventArgs e)
