在DataGridViewCell中捕捉KeyUp事件

本文关键字：KeyUp 事件 DataGridViewCell | 更新日期: 2023-09-27 17:54:31

我正在为DataGridView的特定列中的所有单元格制作自动完成行为。

我已经找了好几个小时了，但是没有找到任何有用的方法。

有许多事件，例如当用户单击其中一个时，当用户在DataGridView中keyup时(被调用的次数太多)，等等。但是在Cell中没有KeyUp事件。

有什么办法吗?

在DataGridViewCell中捕捉KeyUp事件

你可以尝试在列内使用模板字段和文本框然后在上面使用keyup ?

您可以使用datagridview文本框列并设置其自动完成源

像这样，

 AutoCompleteStringCollection scAutoComplete = new AutoCompleteStringCollection();
        private void Form1_Load(object sender, EventArgs e)
        {
            DataTable dt = new DataTable();
            String strConn = "Server = .;Database = NorthWind; Integrated Security = SSPI;";
            SqlConnection conn = new SqlConnection(strConn);
            SqlDataAdapter da = new SqlDataAdapter("Select * from [Order Details]", conn);
            da.Fill(dt);
            dataGridView1.DataSource = dt;
            for (int x = 1; x <= 61000; x++ )
            {
                scAutoComplete.Add(x.ToString());
            }
        }
        private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {
            if (dataGridView1.CurrentCellAddress.X == 1)
            {
                TextBox txt = e.Control as TextBox;
                txt.AutoCompleteCustomSource = scAutoComplete;
                txt.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
                txt.AutoCompleteSource = AutoCompleteSource.CustomSource;
            }
        }
        private void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
        {
            if(e.ColumnIndex==1)
            {
                if(!scAutoComplete.Contains(e.FormattedValue.ToString()))
                {
                    MessageBox.Show("Invalid Data");
                    e.Cancel=true;
                }
            }
        }

这对我来说是有效的(对于一个按键，同样应该是一个键的上下):

Private dgTextbox As TextBox = New TextBox
Private Sub DataGridView1_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing
    RemoveHandler dgTextbox.KeyPress, AddressOf dgTextbox_KeyPress
    dgTextbox = CType(e.Control, TextBox)
    AddHandler dgTextbox.KeyPress, AddressOf dgTextbox_KeyPress
End Sub
Private Sub dgTextbox_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
    'your code goes here
End Sub
