ถ้าใช้ตัวนี้ สามารถใช้ IF ได้ใน RowDataBound ครับ เช่น
Code (VB.NET)
Dim lblUsed As Label = CType(e.Row.FindControl("lblUsed"),Label)
IF Not IsNothing(lblUsed) Then
lblUsed.Text = FormatNumber(e.Row.DataItem("Used"),2)
IF e.Row.DataItem("Status") = "1" Then
lblUsed..ForeColor = Drawing.Color.Green
Else
lblUsed..ForeColor = Drawing.Color.Red
End IF
End IF
