RadDataGrid multiselection and arrow key navigation

[Simon]

Hi,

I would like to use SelectionMode="Extended" for my DataGrid and still be able to navigate through/select rows with arrow keys. Setting IsSynchronizedWithCurrentItem="True", however, disables multiselection. Is there a way to combine the two behaviors?

Thanks for your help

Regards

Simon

Hello Simon,

When the IsSynchronizedWithCurrentItem property of RadDataGrid is set to True, the SelectedItem property's value will be updated, so that it is synchronized with the CurrentItem object. The observed behavior on your end is the default and expected one.

With this in mind, a possible approach for retaining the arrow navigation while there are selected items would be to disable the synchronization with the current item. Is there any requirement in your application to keep the selected item synchronized with the current one? If yes, would it be possible to share it, so I can review it and see if I can suggest an alternative approach that will allow you to keep the arrow navigation?

Hi Stenly,

thanks for your help. Disabling the synchronization is what I did for now. But it makes navigation within the DataGrid a bit cumbersome. I was hoping for a behavior similar to spreadsheet apps like Excel. You can select a single cell with the arrow keys and when holding down the shift key, you can select multiple cells, also using the arrow keys.

With synchronization disabled, you have to hit the space key in order to change the selection, which feels really uncommon.
