datagrid视图中的按键事件？

我需要编写一个简单的函数，当人输入框数时，然后按下按键事件number of boxes*someamount进入金额列。 我使用拖放控件添加了datagridview

我想根据我的研究，这里将编写代码

 private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e) { } 

但我不知道如何把Keyup事件和访问列数字框numberofboxes and Amount 。 谢谢

我已经测试了这个，它通过使用按键事件工作，并将someAmount值乘以someAmount ，每次在单元格中输入一个新数字时，它会自动为您计算。

  public Form1() { InitializeComponent(); MyDataGridViewInitializationMethod(); } private void MyDataGridViewInitializationMethod() { dataGridView1.EditingControlShowing += new DataGridViewEditingControlShowingEventHandler(dataGridView1_EditingControlShowing); } private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e) { e.Control.KeyPress += new KeyPressEventHandler(Control_KeyPress); } private void Control_KeyPress(object sender, KeyPressEventArgs e) { if (char.IsNumber(e.KeyChar)) { string cellValue = Char.ToString(e.KeyChar); //Get the column and row position of the selected cell int column = dataGridView1.CurrentCellAddress.X; int row = dataGridView1.CurrentCellAddress.Y; if (column == 1) { //Gets the value that existings in that cell string test = dataGridView1[column, row].EditedFormattedValue.ToString(); //combines current key press to the contents of the cell test = test + cellValue; int intNumberBoxes = Convert.ToInt32(test); //Some amount to mutiple the numberboxes by int someAmount = 10; dataGridView1[column + 1, row].Value = intNumberBoxes * someAmount; } } } }

对于vb.net

十进制validation：

  Public Sub New() InitializeComponent() MyDataGridViewInitializationMethod() End Sub Private Sub MyDataGridViewInitializationMethod() AddHandler dataGridView1.EditingControlShowing, AddressOf dataGridView1_EditingControlShowing End Sub Private Sub dataGridView1_EditingControlShowing(ByVal sender As Object, ByVal e As DataGridViewEditingControlShowingEventArgs) AddHandler e.Control.KeyPress, AddressOf Control_KeyPress End Sub Dim dotOnce As Boolean Private Sub Control_KeyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs) If e.KeyChar Like "[']" Then e.Handled = True Exit Sub End If If e.KeyChar = "." Then If dotOnce Then e.Handled = True End If dotOnce = True Else If (Not e.KeyChar Like "[0-9 . ]") Then e.Handled = True Exit Sub End If End If End Sub
