bindig of list of objects into telerikGridView:GridViewDataColumn

[lina fetisova]

Good day!
I have a class names Sales:

public class Sales : BaseDomain<br>
{<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; public virtual string Name { get; set; }<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ICollection&lt;ActivityCategory&gt; categories = new
List&lt;ActivityCategory&gt;();<br>
}

I bind this a List of items of this class to a RadGridView:
grid.ItemSource = e.Result;
where e.Result is a List<Sales>.
For column "Name" I make it this way:

<telerikGridView:GridViewDataColumn UniqueName="Name"  Header="Name
of Sale"  />.

How can I make it for ICollection<ActivityCategory> categories to show it in my RadGridView (maybe with a list of text  separated by commas  or with an dynamic number of chek boxes with text)?

Vlad, thank you very much, but can you provide me a more detailed answer, please?

Hi lina fetisova,

To display a collection of values within a single cell , you will need to place an ItemsControl in the cell. Maybe a ListBox will do fine.
To place the ListBox you will need to use the CellTemplate property of the column.
It would be something like :

<telerik:GridViewDataColumn >
    <telerik:GridViewDataColumn.CellTemplate>
        <DataTemplate>
        <ListBox ItemsSource ="{Binding categories}" />
        </DataTemplate>
    </telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn >

Alternatively you may represent the collection as a comma-separated list. For this you will need to use an IValueConverter in the DataMemberBinding of the  column. Within the Convert method of the IValueConverter you will need to turn the collection into a comma -separated string.

In case you have troubles implementing one of these approaches do not hesitate to contact me.

thank you very much!

I write

<telerik:GridViewDataColumn >
    <telerik:GridViewDataColumn.CellTemplate>
        <DataTemplate>
        <ListBox ItemsSource ="{Binding ActivityCategories}" />
        </DataTemplate>
    </telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn >

and see a result:

a list of strings: "CAP.Registrator.ActivityCategory"

CAP.Registrator.ActivityCategory has a property Name.
How can I see exactly this property?

Hello,

You can define desired ItemTemplate for this ListBox.
