【中文标题】在 vb.net 的文本框中显示 datagridview 单元格数据【英文标题】:display datagridview cell data in the textbox in vb.net 【发布时间】:2015-02-21 07:25:12 【问题描述】:我想在相关文本框中显示我的 datagridview1 数据。当我选择 datagridview1 中的任何单元格时,相关数据应显示在文本框中。 这是我做的代码
Private Sub DataGridView1_CellClick(ByVal sender As Object, _
ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) _
Handles DataGridView1.CellClick
Dim i As Integer
i = DataGridView1.CurrentRow.Index
Me.Label8.Text = DataGridView1.Item(0, i).Value
Me.TextBox1.Text = DataGridView1.Item(1, i).Value
Me.TextBox2.Text = DataGridView1.Item(2, i).Value
Me.ComboBox1.Text = DataGridView1.Item(3, i).Value
Me.ComboBox2.Text = DataGridView1.Item(4, i).Value
Me.TextBox5.Text = DataGridView1.Item(5, i).Value
Me.TextBox3.Text = DataGridView1.Item(6, i).Value
Me.TextBox4.Text = DataGridView1.Item(7, i).Value
Me.RichTextBox1.Text = DataGridView1.Item(8, i).Value
Me.RichTextBox2.Text = DataGridView1.Item(9, i).Value
Me.Label14.Text = DataGridView1.Item(10, i).Value
End Sub
我在这里做了另一个代码
Private Sub DataGridView1_CellContentClick(ByVal sender _
As System.Object, ByVal e As _
System.Windows.Forms.DataGridViewCellEventArgs) _
Handles DataGridView1.CellContentClick
Try
If e.RowIndex >= 0 Then
Dim row As DataGridViewRow
row = Me.DataGridView1.Rows(e.RowIndex)
Label8.Text = row.Cells("id").Value.ToString
TextBox1.Text = row.Cells("firstname").Value.ToString
TextBox2.Text = row.Cells("lastname").Value.ToString
ComboBox1.Text = row.Cells("year").Value.ToString
ComboBox2.Text = row.Cells("month").Value.ToString
TextBox5.Text = row.Cells("gender").Value.ToString
TextBox3.Text = row.Cells("address").Value.ToString
TextBox4.Text = row.Cells("telephone").Value.ToString
End If
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
但是两个代码都不起作用,它们会出错。里面的“”标记代表列名
谁能给我vb.net中的解决方案
【问题讨论】:
您不需要任何代码。将数据放入某种列表中,然后将该列表简单地绑定到网格和各个控件。你想要发生的事情就会自动发生。 【参考方案1】:Private Sub DataGridView1_CellClick (ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellClick
Dim i As Integer
With DataGridView1
if e.RowIndex >= 0 Then
i = .CurrentRow.Index
tbID.text = .Rows(i).Cells("id").Value.ToString
tbFirstNametext = .Rows(i).Cells("firstname").Value.ToString
tbLastNametext = .Rows(i).Cells("lastname").Value.ToString
tbAddresstext = .Rows(i).Cells("address").Value.ToString
End If
End With
End Sub
【讨论】:
【参考方案2】:请使用这个,
Private Sub DataGridView1_CellContentClick_1(sender As Object, e As DataGridViewCellEventArgs) Handles DataGridView1.CellDoubleClick
namatxt.Text = Me.DataGridView1.SelectedCells(1).Value.ToString
End Sub

【参考方案3】:这个怎么样?
Private Sub DataGridView1_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellClick
Dim row As DataGridViewRow = DataGridView1.CurrentRow
Me.Label8.Text = row.Cells(0).Value.ToString()
Me.TextBox1.Text = row.Cells(1).Value.ToString()
Me.TextBox2.Text = row.Cells(2).Value.ToString()
Me.ComboBox1.Text = row.Cells(3).Value.ToString()
Me.ComboBox2.Text = row.Cells(4).Value.ToString()
Me.TextBox5.Text = row.Cells(5).Value.ToString()
Me.TextBox3.Text = row.Cells(6).Value.ToString()
Me.TextBox4.Text = row.Cells(7).Value.ToString()
Me.RichTextBox1.Text = row.Cells(8).Value.ToString()
Me.RichTextBox2.Text = row.Cells(9).Value.ToString()
Me.Label14.Text = row.Cells(10).Value.ToString()
End Sub
【讨论】:
【参考方案4】:使用此代码,它对我来说很好用:
Private Sub DataGridView1_CellClick(sender As Object, e As DataGridViewCellEventArgs) Handles DataGridView1.CellClick
If e.RowIndex >= 0 Then
Dim row As DataGridViewRow
row = Me.DataGridView1.Rows(e.RowIndex)
tbID.Text = row.Cells("id").Value.ToString
tbFirstName.Text = row.Cells("firstname").Value.ToString
tbLastName.Text = row.Cells("lastname").Value.ToString
tbAddress.Text = row.Cells("address").Value.ToString
End If
End Sub
将我拥有的列名(即“id”“firstname”“lastname”)等替换为您的列名。

【参考方案5】:要使用上下键导航 DataGridView 行并在文本框中显示所选记录,您可以使用以下命令:
'declare variable
Private DB As New databasenameDataSetTableAdapters.tablenameTableAdapter
'add constructor to your form
Public Sub New()
' This call is required by the designer.
InitializeComponent()
'Setting KeyPreview To True makes sure that the Form1_KeyDown will always
'be called If a key Is pressed,
Me.KeyPreview = True
End Sub
Private Sub form1_KeyDown(sender As Object, e As KeyEventArgs) Handles Me.KeyDown
Select Case e.KeyCode
'if else statement is there otherwise when going through the rows in grid
'it would show the previous row in textboxes instead of current one
'GetData is a select query you can generate by double clicking the dataset.xsd file in solution explorer
Case Keys.Up
Dim rowUp As Integer = dataGridView.CurrentRow.Index
If (rowUp <= 0) Then
rowUp = 0
Else
rowUp = rowUp - 1
End If
Try
txtBox1.Text = DB.GetData.Rows(rowUp).Item(0).ToString
txtBox2.Text = DB.GetData.Rows(rowUp).Item(1).ToString
txtBox3.Text = DB.GetData.Rows(rowUp).Item(2).ToString
Catch ex As Exception
MsgBox(ex.Message)
End Try
Exit Select
Case Keys.Down
Dim rowDown As Integer = dataGridView.CurrentRow.Index
If (rowDown >= DB.GetData.Rows.Count - 1) Then
rowDown = DB.GetData.Rows.Count - 1
Else
rowDown = rowDown + 1
End If
Try
txtBox1.Text = DB.GetData.Rows(rowDown).Item(0).ToString
txtBox2.Text = DB.GetData.Rows(rowDown).Item(1).ToString
txtBox3.Text = DB.GetData.Rows(rowDown).Item(2).ToString
Catch ex As Exception
MsgBox(ex.Message)
End Try
Exit Select
另一种方法是使用 datagridview CellEnter 事件
Private Sub DataGridView1_CellEnter(sender As Object, e As EventArgs)
Handles DataGridView1.CellEnter
Dim row As DataGridViewRow = DataGridView1.CurrentRow
txtBox1.Text = row.Cells(0).Value.ToString()
txtBox2.Text = row.Cells(1).Value.ToString(),
End Sub
【讨论】:
【参考方案6】:Private Sub DataGridView1_CellEnter(sender As Object, e As EventArgs)
Handles DataGridView1.CellEnter
Dim row As DataGridViewRow = DataGridView1.CurrentRow
txtBox1.Text = row.Cells(0).Value.ToString()
txtBox2.Text = row.Cells(1).Value.ToString(),
End Sub

Raju,我怀疑这是否有帮助,甚至根本有效。为了说服我,请解释这是如何工作的以及为什么它应该有所帮助。以上是关于在 vb.net 的文本框中显示 datagridview 单元格数据的主要内容,如果未能解决你的问题,请参考以下文章
