I have a Dictionary<int, float> that I want to bind it to sfDataGrid where user can edit/add/delete keys and values.

How should I do that ?

Thats not  what I asked, Your ItemSource is still ObservableCollection. I need ItemSource to be Dictionary, please read first post.

Something like this

var dictionary = new Dictionary<int, float>();
dictionary.Add(1, 85);
dictionary.Add(2, 96);


sfDataGrid.ItemSource = dictionary;

Where it shows, first column as Key and second column as Value

Hi John,

Based on the information provided, we understand that you are trying to bind a Dictionary as the ItemsSource for the SfDataGrid and would like to support adding and editing values. While this setup may seem straightforward, there are inherent limitations when using a Dictionary in this manner.

The primary issue is that both the Key and Value properties of a dictionary entry are immutable (read-only). As a result, the SfDataGrid does not support editing these values directly—particularly when the Key is displayed in the first column and the Value in the second column.

We have also evaluated the behavior of the default MSDN DataGrid and observed similar constraints. Due to these limitations, we recommend binding your data to the SfDataGrid using a List, ObservableCollection, or IEnumerable of custom objects instead. This approach provides full support for editing and adding new records.

For more details, please refer to the user documentation on data binding in SfDataGrid:

Please let us know if you have any concerns or need further assistance. Thank you for your understanding.
