根据文本框值在Datagridview中突出显示一行

Question

晚上好。

我在VB.Net中有一个程序，可在您编辑一些数据后刷新datagridview。我的问题是在这里填充1000多个记录。

假设我正在编辑第999行，然后单击“更新”，数据将刷新，导致datagridview返回顶部（蓝色荧光笔）

我的目标是更新后如何将其保持在当前位置？

我的解决方案是突出显示Textbox1 = value的数据

这样可能吗？

'SAMPLE CODE
Datagridview1.Column(0).value.BlueHighLighter = Textbox1.text

请查看有关如何刷新DGV的代码

  Dim con11 As MySqlConnection = New MySqlConnection("server=192.168.2.87;userid=root;password=admin1950;database=inventory")
        Dim sql1 As MySqlCommand = New MySqlCommand("select PONo,ItemCode,Description,QtyPack,PackUoM,QtyStan,StanUoM,UnitPrice,Total,Remarks,ExpiryDate from Receiving where RINo = '" & Add_Receiving_Items.TextBox1.Text & "';", con1)
        Dim ds1 As DataSet = New DataSet
        Dim adapter1 As MySqlDataAdapter = New MySqlDataAdapter
        con1.Open()
        adapter1.SelectCommand = sql1
        adapter1.Fill(ds1, "MyTable")
        Add_Receiving_Items.DataGridView1.DataSource = ds1.Tables(0)
        con1.close()
        With Add_Receiving_Items.DataGridView1()
            .RowHeadersVisible = False
            .Columns(0).HeaderCell.Value = "PO No"
            .Columns(1).HeaderCell.Value = "Item Code"
            .Columns(2).HeaderCell.Value = "Description"
            .Columns(3).HeaderCell.Value = "Quantity/Pack"
            .Columns(4).HeaderCell.Value = "Packaging UoM"
            .Columns(5).HeaderCell.Value = "Quantity/Pc"
            .Columns(6).HeaderCell.Value = "Standard UoM"
            .Columns(7).HeaderCell.Value = "Unit Price"
            .Columns(8).HeaderCell.Value = "Total"
            .Columns(9).HeaderCell.Value = "Remarks"
            .Columns(10).HeaderCell.Value = "Expiry Date"
        End With

        Add_Receiving_Items.DataGridView1.Columns.Item(0).Width = 80
        Add_Receiving_Items.DataGridView1.Columns.Item(1).Width = 80
        Add_Receiving_Items.DataGridView1.Columns.Item(2).Width = 120
        Add_Receiving_Items.DataGridView1.Columns.Item(3).Width = 86
        Add_Receiving_Items.DataGridView1.Columns.Item(4).Width = 68
        Add_Receiving_Items.DataGridView1.Columns.Item(5).Width = 75
        Add_Receiving_Items.DataGridView1.Columns.Item(6).Width = 68
        Add_Receiving_Items.DataGridView1.Columns.Item(7).Width = 70
        Add_Receiving_Items.DataGridView1.Columns.Item(8).Width = 80
        Add_Receiving_Items.DataGridView1.Columns.Item(9).Width = 105
        Add_Receiving_Items.DataGridView1.Columns.Item(10).Width = 63
        Add_Receiving_Items.DataGridView1.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.BottomCenter
        Add_Receiving_Items.DataGridView1.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.BottomCenter
        With Add_Receiving_Items.DataGridView1
            .RowsDefaultCellStyle.BackColor = Color.WhiteSmoke
            .AlternatingRowsDefaultCellStyle.BackColor = Color.Lavender
        End With

使用DataGridView.CurrentRow属性。 但是请注意， CurrentRow为ReadOnly ，必须使用CurrentCell

在刷新数据存储之前， Dim oldIndex = DataGridView.CurrentRow.Index以及刷新后设置DataGridView.CurrentCell = DataGridView.Rows(oldIndex).Cells(0)

如何测试代码

创建一个带有Button1和一个带有两列的DataGridView1的表单，并粘贴以下代码：

Public Class Form1
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        For i = 1 To 5
            DataGridView1.Rows.Add("foo" & i, "bar" & i)
        Next
    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

        Dim currentIndex = DataGridView1.CurrentRow.Index
        currentIndex += 1
        If currentIndex >= DataGridView1.Rows.Count Then currentIndex = 0

        DataGridView1.CurrentCell = DataGridView1.Rows(currentIndex).Cells(0)
    End Sub
End Class

编辑：

Dim oldIndex = DataGridView.CurrentRow.Index
'Put your code here on how you refresh your data
DataGridView.CurrentCell = DataGridView.Rows(oldIndex).Cells(0)
