Question

I want a grid in xaml tha can show me a collection of objects how should i proceed ?

I already binded these :

C# // Collection.DataContext = Mycollection;

xaml // Grid.RowSpan="{Binding getSizeofcollection}"

My collection contains all the same kind of object. I want to show 1 object/row

Is that possible to create a template of how to show an object in a row then use it in the grid ?

Thanks for your advices

Edit : In fact i can't bind to hashtables, but i can bind to a List that's the source of my problems. Now i'm currently trying to transform my hashtable in a List

Edit n°2 : Ok i convert hashtable to a list correctly, but this xamlparse Exception is still here

Was it helpful?

Solution

A Grid is a layout container, not a control. You want to use a DataGrid, which will allow you to set the ItemsSource to your Mycollection. You can then either let it create the columns for you, or you take control and specifically define what columns you want and how they should be shown.

OTHER TIPS

I'm sorry, I'm finding your question is a bit unclear as to what you're asking for.

Based on your comment here

I have a List of the same objects and i want each objects and their properties in a line of the DataGrid/StackPanel or something So, 20 objects, 20 lines, A collumn for each property

It sounds like you just want a DataGrid.

<DataGrid x:Name="Collection" ItemsSource="{Binding }" />

The default behavior of a DataGrid is to create a Row for each item, and to auto-generate a column for each property of the item. So if you have 20 objects of type MyClass in a list, and each contained 3 properties, it would auto-generate a grid with 20 rows and 3 columns.

However if I have misunderstood you and you're actually looking to create a horizontal StackPanel containing all your items in a line, and you don't need the selection/sorting capabilities that a DataGrid provides, I'd recommend using an ItemsControl instead.

This is simply a control that will iterate over a collection, and draw each item in the collection with whatever template you specify. All the items get wrapped in a <ContentPresenter> and placed in whatever layout container you specify (default is a vertical StackPanel).

Since you said you want all items in a horizontal line, the best ItemsPanelTemplate would probably be a StackPanel with it's orientation set to Horizontal.

Your XAML would end up looking like this:

<ItemsControl x:Name="Collection" ItemsSource="{Binding }">
    <!-- ItemsPanelTemplate -->
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Horizontal" />
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>

    <!-- ItemTemplate -->
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <!-- // put whatever XAML you want to use to draw each item here -->
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

You can use some custom AttachedProperty.

Something like this:

<Grid Grid.Row="1"
              commonUI:GridExtension.ItemsSource="{Binding ItemsSource}"
              commonUI:GridExtension.Rows="{Binding RowDefinitions}"
              commonUI:GridExtension.Columns="{Binding ColumnDefinitions}"/>

But in your case, a simple ListBox or ItemsControl seem to be more appropriate...
