[Lennart]

Hi

Im trying to bind a Dictionary to a Grid, but cant get the value out:

public Dictionary<int,string> Value1 { get; set; }

Value1 value;

(DataGrid.ItemSource =  value)

<telerikGrid:RadDataGrid x:Name="DataGrid">
 <telerikGrid:RadDataGrid.Columns>
  <telerikGrid:DataGridTextColumn PropertyName="Value1[1].Value" Header="Value"/> // I have try
  <telerikGrid:DataGridTextColumn PropertyName="Value1[1]" Header="Value"/> // and
 </telerikGrid:RadDataGrid.Columns>
</telerikGrid:RadDataGrid>

Hi Lennart,

Thank you for your interest.

In its current version our RadDataGrid does not support binding to a Dictionary, but in our Q1 2013 SP1 which will be available next week, it will support such scenario.
As our RadDataGrid does not support binding to nested properties, the implementation should look like this:

<telerikGrid:RadDataGrid  ItemsSource="{Binding}"
                          AutoGenerateColumns="False">
    <telerikGrid:RadDataGrid.DataContext>
        <local:ViewModel/>
    </telerikGrid:RadDataGrid.DataContext>
    <telerikGrid:RadDataGrid.Columns>
        <telerikGrid:DataGridTextColumn Header="Key" PropertyName="Key"/>
        <telerikGrid:DataGridTextColumn Header="Value" PropertyName="Value"/>
    </telerikGrid:RadDataGrid.Columns>
</telerikGrid:RadDataGrid>

Where our ViewModel is: 

public class ViewModel
 {
     public ViewModel()
     {
         Dictionary<int, string> myDictionary = new Dictionary<int, string>();
         myDictionary.Add(1, "first");
         myDictionary.Add(2, "second");
         myDictionary.Add(3, "third");

         this.DataContext = myDictionary;
     }
 }

I hope this helps. Let me know if you need further assistance.

 

All the best,
