Question

我有一个问题，我有一些动态按钮。我想存储整数值。

并在该按钮的单击事件上获取该值，我该如何实现它

提前谢谢沙善

DataView dv = new DataView(dtCat, "PK_CATEGORY_ID IN(" + categoryIds.ToString() + "0)", "PK_CATEGORY_ID", DataViewRowState.CurrentRows);

foreach (DataRowView rr in dv)
{
    //MessageBox.Show(rr[0].ToString() + "------------" + rr[1].ToString());

    Button b2 = new Button();

    //b2.Name = rr[0].ToString();
    b2.Name = "";
    b2.Height = 200;
    b2.Width = 200;
    b2.Margin = new Thickness(0, -100, 0, 0);
    b2.HorizontalAlignment = HorizontalAlignment.Left;
    b2.Content = rr[1].ToString();
    b2.Background = System.Windows.Media.Brushes.Pink;
    b2.Click += new RoutedEventHandler(b2_Click);
    btncanvas.Children.Add(b2);
    Canvas.SetLeft(b2, b2.Width * i);
    i = i + 1;
    MessageBox.Show(rr[0].ToString());
    b2.Tag = rr[0].ToString();

}


void b2_Click(object sender, RoutedEventArgs e)
{
    Button clicked = (Button)sender;

    categoryname = clicked.Name;
}

Tag属性可能就是你想要的。

您已在示例中使用它，但只有：

b2.Tag = integerValue;

然后在您的点击处理程序中使用Convert.ToInt32(object)方法返回整数值：

int retrievedValue = Convert.ToInt32(clicked.Tag);

如何在运行时将值存储在按钮中？
