Question

我使用VS 2012 asp.net web项目和VB.net作为编程语言。我的表单上有一个textbox字段，其textmode属性设置为Date（Datepicker）。

当我运行以下代码时，我无法检索记录中保存的日期，

Protected Sub Srch_Click(sender As Object, e As EventArgs) Handles Srch.Click        
Dim ARTSQLCON As SqlConnection = New SqlConnection("Data Source=EMBRYOLOGIST;Initial Catalog=ARTSQL;Integrated Security=True")
        Try
            ARTSQLCON.Open()
            If Not Len(FilenumSrc.Text) = 0 Then
                Dim sqlread = New SqlCommand
                sqlread.CommandText = "SELECT Filenum, DOB FROM TblReg WHERE Filenum = " & FilenumSrc.Text
                sqlread.Connection = ARTSQLCON
                Dim dr As SqlDataReader
                dr = sqlread.ExecuteReader
                If dr.HasRows Then
                    dr.Read()
                    FileNumTxt.Text = dr.Item("Filenum")
                    DobTxt.Text = dr.Item("DOB")
                    dr.Close()
                End If
            End If
        Catch ex As Exception
        Finally
            ARTSQLCON.Close()
        End Try 
end sub

Answer 1

Dim dt As DateTime = Convert.ToDateTime(dr. 
Item("DOB").ToString())
DobTxt.Text = String.Format("{0:yyyy-MM-dd}", dt)

ref.: data binding

带有textmode = date的文本框不会在executereader
