How do I keep the value in RadGridView edit mode after I've left the cell.

[Pavel]

I am trying to build a role access control, and have a grid with roles and bunch of checkboxes on each row. But, when I try to check multiple checkboxes, my previous check goes away. I want to be able to check multiple boxes and then hit save below.

I think I am missing a property of a grid, so here's the entire code.Thanks!

Hi Pavel,

Thank you for writing.

You are binding the grid to an array of anonymous object and since these object properties cannot be changed the old value is returned. Instead using such objects you can just add the rows to the grid:

radGridView1.Rows.Add("admin", true, true, true, true);

I hope this will be useful. Let me know if you have additional questions.

@Dimitar, thank you! Anonymous objects will be my downfall someday :)
