[Solved] RadGridView binding to simple collection of strings?

[Patrick Holloway]

Given a simple collection of strings, like this:

 

 

ObservableCollection<string> items = new ObservableCollection<string>();
for (int i = 0; i < 5; i++) {
   items.Add(String.Format(itemName + ".Item" + i));
}

binding to a plain gridview like this:

aGridView.ItemsSource = items;

gives us a gridview with one column named "Length" and rows populated with the string.Length of the items in the collection.

We can also see this behavior on the Telerik demo page, here:

http://demos.telerik.com/silverlight/beta/#GridView/DataSources

Clicking on the "Simple List" option binds the gridview to a simple list of strings, shown in the example code like this:

List<string> list = new List<string>();
   foreach (Customer customer in ExamplesDB.GetCustomers())
   {
       list.Add(customer.ContactName);
   }

but again, it does not display a list of customer names, but a column named "Length", and rows populated with string.Length of the items in the collection.

Is this really the desired behavior? What if I actually want to show the strings, and not their length?

Thanks.

Hi Patrick,

Indeed with auto-generated columns you will get this since the grid will try to resolve all public properties of the element type. To handle your scenario you can declare your own column like this:

<telerik:RadGridView ItemsSource="{Binding}">
  <telerik:RadGridView.Columns>
     <telerik:GridViewDataColumn Header="YourHeader" DataMemberBinding="{Binding}"/>
  </telerik:RadGridView.Columns>
</telerik:RadGridView>


Best wishes,
