[英]How do I get the values from a dynamically created NumericUpDown?
如何從C#中的動態NumericUpDown
獲取值?
這是我的代碼,
for (int i=0; i<n;i++)
{
NumericUpDown notele = new NumericUpDown();
notele.Name = "note" + i.ToString();
notele.Location = new System.Drawing.Point(280, 208 + (30 * i));
notele.Size = new System.Drawing.Size(40, 25);
notele.BackColor = System.Drawing.SystemColors.ControlDark;
notele.Maximum = new decimal(new int[] {10,0,0, 0});
this.Controls.Add(notele);
}
使用窗體的Control集合訪問控件,並將其傳遞給numericUpDown
控件的名稱:
var numericUpDown = this.Controls["note0"] as NumericUpDown;
if(numericUpDown != null)
{
var value = numericUpDown.Value;
}
您仍然可以使用ValueChanged事件:
...
notelle.ValueChanged += UpDnValueChangedHandler;
this.Controls.Add(notele);
}
private void UpDnValueChangedHandler(object sender, EventArgs e)
{
// sender references the control which value was changed:
NumericUpDown notelle = sender as NumericUpDown;
// further processing goes here
}
