Question

我在VB.NET中创建一个Windows窗体，并将datagridview设置为只读两列。

datagridview连接到SQL Server数据库，我引用了两个表。第一列是图像，第二列是4列的串联：Rank，LName，Title，FName。我将第二列设置为wrap，但实际上我需要在名称上方显示Rank，所有这些都在同一个单元格中。

示例：

（Rank）人力资源总监

（姓名）Doe，Jane

目前显示为：

人力资源总监Doe，

简

以下是我目前的代码：

Imports System.Data.SqlClient

Public Class some_digital_directory

Dim conDatabase As New SqlConnection("Server=servername;Database=dbname;Integrated Security=True")

Private Sub some_digital_directory_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    Dim comSQL As SqlCommand = conDatabase.CreateCommand()

    comSQL.CommandText = "SELECT B.IMAGE01, A.RANK + ' ' + A.LNAME + ' ' + A.TITLE + ', ' + A.FNAME AS NAME
        FROM EMPMAST AS A LEFT JOIN PICTURE AS B ON A.PERNO=B.PERNO
        WHERE A.HIDE <>'TRUE' AND NAME <>' '
        ORDER BY A.LNAME, A.FNAME, A.MNAME"

    Dim adptSQL As New SqlDataAdapter()
    Dim tblEmployees As New DataTable()

    adptSQL.SelectCommand = comSQL
    conDatabase.Open()
    adptSQL.Fill(tblEmployees)
    conDatabase.Close()

    dgvEmployees.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill
    dgvEmployees.RowTemplate.Height = 150
    dgvEmployees.ScrollBars = ScrollBars.Vertical
    dgvEmployees.DataSource = tblEmployees

    Dim imgPerson As New DataGridViewImageColumn()

    imgPerson = dgvEmployees.Columns(0)
    imgPerson.ImageLayout = DataGridViewImageCellLayout.Zoom

您可以在撰写字符串时添加CRLF，而不是

A.RANK + ' ' + A.LNAME + ' ' + A.TITLE + ', ' + A.FNAME AS NAME

你会有

A.RANK + ' ' + A.LNAME + CHAR(13) + CHAR(10) + A.TITLE + ', ' + A.FNAME AS NAME

虽然在我看来你在LNAME列中有TITLE，反之亦然。

编辑：根据您的评论，您可能需要：

A.RANK + CHAR(13) + CHAR(10) + A.TITLE + ', ' + A.FNAME AS NAME

所以你最终会得到：

Dim connStr As String = "Server=servername;Database=dbname;Integrated Security=True"

Private Sub some_digital_directory_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    Using conDatabase As New SqlConnection(connStr)

        Using comSQL As SqlCommand = conDatabase.CreateCommand()

            comSQL.CommandText = "SELECT B.IMAGE01, A.RANK + CHAR(13) + CHAR(10) + A.TITLE + ', ' + A.FNAME AS NAME
    FROM EMPMAST AS A LEFT JOIN PICTURE AS B ON A.PERNO=B.PERNO
    WHERE A.HIDE <>'TRUE' AND NAME <>' '
    ORDER BY A.LNAME, A.FNAME, A.MNAME"

            Dim adptSQL As New SqlDataAdapter()
            Dim tblEmployees As New DataTable()

            adptSQL.SelectCommand = comSQL
            adptSQL.Fill(tblEmployees)

        End Using

    End Using

    ' rest of code here
End Sub
