Project: I have a parent panel which holds a ComboBox and FlowLayoutPanel. The FlowLayoutPanel holds a variable number of child panels (a custom control th
Posting this answer because the OP requested it:
This is how you'd do something like that in WPF:
Code Behind (only boilerplate to support the example)
public partial class ListBoxSample : UserControl
{
public ListBoxSample()
{
InitializeComponent();
}
public void LoadData()
{
Task.Factory.StartNew(() =>
{
var list = new List();
for (int i = 0; i < 100000; i++)
{
var item = new DataItem()
{
From = "1",
To = "2",
ChildItems =
{
new ChildItem()
{
DependeeFrom = i.ToString(),
DependeeTo = (i + 10).ToString(),
XXXX = "XXXX"
},
new ChildItem()
{
DependeeFrom = i.ToString(),
DependeeTo = (i + 10).ToString(),
XXXX = "XXXX"
},
new ChildItem()
{
DependeeFrom = i.ToString(),
DependeeTo = (i + 10).ToString(),
XXXX = "XXXX"
}
}
};
list.Add(item);
}
return list;
}).ContinueWith(t =>
{
Dispatcher.Invoke((Action) (() => DataContext = t.Result));
});
}
private void Load_Click(object sender, System.Windows.RoutedEventArgs e)
{
LoadData();
}
}
Data Items:
public class DataItem
{
public List ChildItems { get; set; }
public List FromOptions { get; set; }
public List ToOptions { get; set; }
public string From { get; set; }
public string To { get; set; }
public DataItem()
{
ChildItems = new List();
FromOptions = Enumerable.Range(0,10).Select(x => x.ToString()).ToList();
ToOptions = Enumerable.Range(0, 10).Select(x => x.ToString()).ToList();
}
}
public class ChildItem
{
public string XXXX { get; set; }
public string DependeeFrom { get; set; }
public string DependeeTo { get; set; }
}
Then you put that in an existing winforms UI using an ElementHost:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
var elementHost = new ElementHost
{
Dock = DockStyle.Fill,
Child = new ListBoxSample()
};
Controls.Add(elementHost);
}
}
Result:
DataGrid
