如何在vb.NET的dataGridView中放置搜索功能

如何从datagridView中的选定行中选择一个单元格，并在选择后设置简单的搜索功能（就像我们在windows文件夹中键入任何字符，搜索应该可以正常工作）？

我不太理解您的问题。如果要选择一个单元格，可以使用celldoubleclick事件作为示例。要获取所选单元格，请使用e.rowindex和e.columnindex，这将为您提供单元格所在的行和列。

您可以尝试使用此解决方案

Dim nwData as CustomersDataSet = CustomersDataSet.GetCustomers()
m_CustomersGrid.DataSource = m_CustomersBindingSource
m_CustomersBindingSource.DataSource = nwData.Customers

Then you can sort using the BindingSource.

CustomersBindingSource.Sort = "ContactName ASC"

And you can find using the BindingSource.

Dim index as integer = _
CustomersBindingSource.Find("CompanyName", CompanyNameTextBox.Text)
If index <-1 then 'it was found; move to that position
CustomersBindingSource.Position = index
End If

在单元格中按下按键时，通过使用以下方式捕捉按键：

 Private Sub DataGridView1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyUp
        Dim dgv As DataGridView = TryCast(sender, DataGridView)

        If dgv IsNot Nothing Then

           'You will need some logic here to determine how long to wait between keyups 
           'Perhaps a timer that ticks every500 milliseconds and reset on keyup.  
e.KeyData
            End If
        End Sub

找到了原始的竞价源逻辑，我想把简单的搜索功能放在我们的目录或文件夹中。比如，如果你输入'ab'，所有以ab开头的文件都列在第一位，这与我想申请dataGridView的内容是一样的。

 Private Sub DataGridView1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyUp
        Dim dgv As DataGridView = TryCast(sender, DataGridView)

        If dgv IsNot Nothing Then

           'You will need some logic here to determine how long to wait between keyups 
           'Perhaps a timer that ticks every500 milliseconds and reset on keyup.  
e.KeyData
            End If
        End Sub
