关于遍历VB.net窗体里面控件的问题可以vb.net控件遍历的vb.net控件遍历,需要判断控件类型并做一下类型转换 。
For Each c As Control In Me.Controls
If TypeOf(c) Is TextBox Then
Dim t As TextBox = CType(c ,TextBox)
'调用tvb.net控件遍历的方法即可
End If
Next
vb.net怎么遍历所有控件,使Click都执行相同的过程c# 用程序转的vb.net控件遍历,也不知道对不对 。你看看有没有帮助 ,这是遍历所有控件,还有一个办法就是重载form的消息处理函数应该也是可以的 。
STAThread _
Public Shared Sub Main(args As String())
Dim button = New Button()
button.Text = "vb.net控件遍历我是按钮"
button.Dock = DockStyle.Fill
Dim form = New Form()
form.Controls.Add(button)
CapturehMouseClickEvent(form)
form.ShowDialog()
End Sub
Private Shared Sub CapturehMouseClickEvent(control As Control)
AddHandler control.Click, AddressOf ControlOnClick
For Each subControl As Control In control.Controls
CapturehMouseClickEvent(subControl)
Next
End Sub
Private Shared Sub ControlOnClick(sender As Object, eventArgs As EventArgs)
Debug.WriteLine("控制被单击")
End Sub
用vb.net如何 编程遍历页面上所有TextBox控件并给它赋值为string.Empty?For Each ctl As Control In Me.Controls If TryCast(ctl, TextBox)Nothing Then Dim txt As TextBox = TryCast(ctl, TextBox) txt.Text = "" End If
vb.net中如何遍历程序窗体中的控件?并读写控件的数据 。Public Sub GetAllControls(ByVal InContainer As Control, ByRef RecieveList As ListBox)
For i As Integer = 0 To InContainer.Controls.Count - 1
If InContainer.Controls.Item(i).Text"" Then
GetList.Items.Add(InContainer.Controls.Item(i).TextvbCrLf)
End If
If InContainer.Controls.Item(i).Controls.Count0 Then
GetAllControls(InContainer.Controls.Item(i), GetList)
【vb.net控件遍历 vb遍历子窗口】End If
Next
End Sub
这段代码可行,但不能遍历菜单和工具栏,要按需要修改
VB.NET 遍历 DataGridView遍历的例子:
Dim i, j As Integer
For i = 0 To DataGridView1.RowCount - 1
For j = 0 To DataGridView1.ColumnCount - 1
MsgBox(DataGridView1.Item(j, i).Value)
Next
Next
注意:与Excel的单元格命名规则不一样,这里的 Item(j, i) 中,列号 j 在前,行号 i 在后 。
vb.net panel里的控件如何遍历Public Sub ReSetText(Control ctrl)
Dim ct As Control
For Each ct In ctrl.Controls
Try
For Each ct2 As Control In ct.Controls
ReSetText(ct2)
Next
Catch
End Try
If (TypeOf ct Is TextBox) Then
ct.Text = ""
ElseIf (TypeOf ct Is ComboBox) Then
Dim cb As System.Windows.Forms.ComboBox = DirectCast(ct, System.Windows.Forms.ComboBox)
cb.SelectedIndex = -1
End If
Next
End Sub
因为textbox在窗体里的panel里,你只遍历窗体的控件是不够的 。
