[英]display datagridview cell data in the textbox in vb.net
i want to display my datagridview1 data in relevant textboxes.我想在相关文本框中显示我的 datagridview1 数据。 when i select any cell in the datagridview1 relevant data should be displayed in textboxes.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。 here is the code i did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
i did another code here it is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
however both codes are not working they give errors.但是两个代码都不起作用,它们会出错。 inside the "" marks represent the column name "" 内的标记代表列名
can anyone give me the solution in vb.net谁能给我在 vb.net 中的解决方案
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
Please use this,请用这个,
Private Sub DataGridView1_CellContentClick_1(sender As Object, e As DataGridViewCellEventArgs) Handles DataGridView1.CellDoubleClick
namatxt.Text = Me.DataGridView1.SelectedCells(1).Value.ToString
End Sub
How about this?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
Use this code, it works fine for me: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
replace the names of the columns i have (ie "id" "firstname" "lastname") etc with the name of your columns.用您的列名替换我拥有的列名(即“id”“firstname”“lastname”)等。
To navigate through DataGridView rows with up and down keys and show the selected record in textboxes you can use this:要使用向上和向下键浏览 DataGridView 行并在文本框中显示所选记录,您可以使用:
'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
Another way of doing it use the datagridview CellEnter event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
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
