Assuming that I have the following xaml code:

<UserControl x:Class="Test.DateList"<br />
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"<br />
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"<br />
    xmlns:c="clr-namespace:Test"><br />
<DockPanel><br />
  <StackPanel><br />
    <RadioButton Checked="YMD"> Show YMD </RadioButton><br />
    <RadioButton Checked="MDY"> Show MDY </RadioButton><br />
  </StackPanel><br />
  <ListView Name="list"><br />
     <ListView.ItemTemplate><br />
        <DataTemplate><br />
           <TextBlock Text="{Binding Path=Date, Converter=???" /><br />
        </DataTemplate><br />
     </ListView.ItemTemplate><br />
  </ListView><br />
</DockPanel>

and the following class:

[ValueConversion(typeof(DateTime), typeof(String))]<br />
partial class DateList : UserControl, IValueConverter<br />
{<br />
   enum Form { YMD, MDY }<br />
   Form DateForm = YMD;<br />
   public DateList()<br />
   {<br />
       InitializeComponent();<br />
<br />
       // initialize the content of the ListView<br />
       List<DateTime> dates = new List<DateTime>();<br />
       for (int i=0;i<10;i++)<br />
           dates.Add(DateTime.Today + TimeSpan.FromDays(i));<br />
       list.ItemsSource = dates;<br />
   }<br />
  void YMD(object sender, RoutedEventArgs e)<br />
  {<br />
     DateForm = Form.YMD;<br />
     list.InvalidateVisual();<br />
  }<br />
  void MDY(object sender, RoutedEventArgs e)<br />
  {<br />
     DateForm = Form.MDY;<br />
     list.InvalidateVisual();<br />
  }<br />
  public object Convert(object value, Type targetType, object parameter, CultureInfo culture)<br />
  {<br />
      DateTime dt = (DateTime)value;<br />
      DateList dl = parameter as DateList;<br />
      if (dl != null)<br />
      {<br />
        switch (dl.DateForm)<br />
        {<br />
          case Form.YMD: return dt.ToString("yyyy/MM/dd");<br />
          case Form.MDY: return dt.ToString("MMM dd, yyyy");<br />
        }<br />
      }<br />
      return null;<br />
  }<br />
  public Object ConvertBack(object value, Type targetType, object parameter, CultureInfo ci) { return null; }<br />
}

How can I link the converter in the data template to correctly display the dates?

As I've coded the example, my thoughts were to use the ConverterParameter and to pass the reference
to the class, but I don't know how to set this to anythign other than a static value within the xaml file.

Any suggestions would be greatly appreciated.

Ditto what Henry said and use pre tags for more than one line of code, rather than code tags.

How to declare/tie a mdigrandchild form to mdiGrandParent form?

I dont understand, why are you searching for a readymade code...

All these forums and members here are just to help if you get stuck with something but not to completely do your work...

I dont think its too hard to convert a C# code in to VB.Net Code, if you know the basics and syntax of VB.Net...

Please give a try yourself... That will enhance your ideas and programming skill as well....

My hearty wishes for a successful project....

Have a Happy Coding.....

How to declare/tie a mdigrandchild form to mdiGrandParent form?
Situ:
I'm writing some code/mdiParent that spawns a child form, child1, that has all the information capturing. Now child1 spawns a child, grandchild. The grandchild is a lean version of child1, readonly type situation. Child1 is not shown, but working. Grandchild is to: Grandchild.show().

Needed:
I need to declare the grandchild to show in the mdiParent. I'm sure it's somthing similar to :

The parent is MainIndiv_Truck_ControlMDI : Form

the child1 is declared in the parent as:

Indiv_Truck_Control TruckForm = new Indiv_Truck_Control();
TruckForm.MdiParent = this.

I know I'm missing something. I can make the grandchildren, but there happening outside the MdiParent. I want them to happen inside MainIndiv_Truck_ControlMDI : Form

Thanks in advance.L.

25-Mar-09 11:24

I am not sure that I totally understand your question, but I think that you want the grandchild form to be bound within the parent form?

If that is so, just set the grandchild forms' mdiparent property to the parent form as well.

Lecutus126-Mar-09 7:53

I would but what is the method if I can't use:

The parent is MainIndiv_Truck_ControlMDI : Form

the child1 is declared inside the parent as:

child1 = Indiv_Truck_Control TruckForm = new Indiv_Truck_Control();
TruckForm.MdiParent = this;

Then child1 spawns a child of its own, grandchild.

The grandchild has to be inside the MainIndiv_Truck_ControlMDI : Form.
grandchild.Mdiparent = "what"?
I'm not sure how to say the "what"? part.

Thanks

For the grandchild form to be contained inside the grandparent form it must be

grandchild.Mdiparent = MainIndiv_Truck_ControlMDI

otherwise it won't be contained.

You can put a form inside another, but you won't get the benefits of the MDI interface.
Like this:

Form grandchild = new grandchildForm();
grandchild.TopLevel = false;
grandchild.Parent = MainIndiv_Truck_ControlMDI;
grandchild.Visible = true;
grandchild.Location = new Point(10, 10);
grandchild.Size = new Size(100, 150);
grandchild.BackColor = Color.Bisque; // or whatever. this is just to make it stand out
MainIndiv_Truck_ControlMDI.Controls.Add(grandchild);

Ok, I've Googled myself silly. I need to create a List<> instance based on a System.Type instance, the list must not contain a bunch of Type instances like List<system.type> x;</system.type> but more like:

Type objectType = objectInstance.GetType();
List<objectType> objects = new List<objectType>(); //This is where I need to create the list based on the Type
objects.Add(objectInstance);//This shouldn't give an error

The binding of generic parameters occurs at (mostly) compile-time. Unfortunately, what you want can't be done at run-time. The closest you can get is with using Reflection.

Type objectType = objectInstance.GetType();

<span style="color:green">// Create a generic list bound to the Type.</span>
Type unboundListType = <span style="color:blue">typeof</span>(List<> );
Type boundListType = unboundListType.MakeGenericType(<span style="color:blue">new</span> Type[] {objectType});
ConstructorInfo ctor = boundListType.GetConstructor(Type.EmptyTypes);
<span style="color:blue">object</span> genericBoundList = ctor.Invoke(<span style="color:blue">null</span>);

<span style="color:green">// Add a thing to the list.</span>
MethodInfo info = boundListType.GetMethod("Add");
info.Invoke(genericBoundList, <span style="color:blue">new object</span>[] { <span style="color:blue">new</span> Moo() });

Hope that helps.

Thanks for the help, did the trick. Took me a whle to understand what was going on... I'm already using reflection extensively so this fits in to the rest of my design
