Hi,

We would like our users to perform "undo/redo" in the GridView (at the very least, "undo") as in Excel where users can "undo/redo" changes in each cell.

Could you please help in providing an example of how to accomplish this scenario?

We are using MVVM with observable properties and observable collections.

 

Kind regards

Hello Abhinav,

There is no out-of-the-box functionality for satisfying this requirement. A possible solution might be to adopt the approach demonstrated in the Undo Functionality in Grid forum thread.

Hopefully, it helps.

Hi Stefan X1,

Thank you for your reply. We use a model (list of objects) as the data source instead of DataTable.DefaultView. Is there a recommended way to incorporate the attached demo using a model that we bind to instead of a DataTable? For example, binding the ItemSource of the gridview to a ObservableCollection or other collection of objects via MVVM?

Example XAML:

<telerik:RadGridView Grid.Row="1" 
                             Name="dtgMyData" 
                             ItemsSource="{Binding Path=MyData}"

...

Will Telerik release a version of the gridview that supports undo/redo, as this is a common request for users?

 

Kind regards

Hello Abhinav,

Thanks for clarifying this.

Speaking in general, you should be able to implement the same approach with an ObservableCollection, as it supports inserting/removing items at specific index.

As to having this functionality built-in for RadGridView, I do agree that this would be a nice feature. I will log it in our backlog for future implementation. Before that, may I ask you to share some additional information regarding your exact setup and usage of the control, so I can add it as a comment in the item in our system if needed?

Thanks in advance for your cooperation.

Hi Stefan X1,

Thanks for your suggestions.

We are currently using WPF/MVVM/Prism/Unity with Telerik for WPF version 2016.2.613.45.

We have ObservableCollections bound to the ItemSource of the Datagrid, with Observable properties, implementing INotifyProperyChanged (via Prism's BindableBase). We are using the "Extended" selection mode of the RadGridView with a "Mixed" SelectionUnit. We are utilizing both SelectedItems and SelectedCells and have implemented a custom feature for copy/paste and programmatic filtering functionality for a large amount of records (1M+). We'd like to implement and undo/redo feature on the RadGridView, where users can type Ctrl-Z/Ctrl-Shift-Z (for example), and have the history of changes undone/redone in each cell that was modified - our users may modify large amounts of data all at once by issuing the custom copy/paste command. We'd like to stay with a Pure MVVM approach as much as possible.

Please let me know if you'd like additional information.

 

Kind regards

Hello Abhinav,

As this is a relatively big task, we would not be able to implement it for the next official release. Hopefully, we would manage to do so for one of the next ones, but I am afraid that I cannot commit myself to a certain time frame.
