子页面向父页面传值。
子页面代码：
public delegate void DeleteSelected(string id);
public event DeleteSelected DoDelete;
private void image1_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
if (DoDelete != null)
{
Image img=sender as Image;
DoDelete(img.Tag.ToString().Trim());
}
}
父页面代码：
{
GetTradeControl getTrade = new GetTradeControl(id, wareName, 1, price);
getTrade.DoDelete += new GetTradeControl.DeleteSelected(getTrade_DoDelete);
this.grd_get.Children.Add(getTrade);
}
void getTrade_DoDelete(string id)
{
GetTradeControl gtc_ = null;
foreach (GetTradeControl gtc in this.grd_get.Children)
{
if (gtc.Id == id)
{
//this.grd_get.Children.Remove(gtc);
gtc_ = gtc;
}
}
this.grd_get.Children.Remove(gtc_);
}
