问题 I'm still fighting with manipulation of cell backgrounds so I'm asking a new question. A user "H.B." wrote that I can actually set the cell style during the AutoGeneratingColumn event - Change DataGrid cell colour based on values. The problem is that I'm not sure how to do it. What I want: Set different background colours for each cell depending on its value. If the value is null I also want it not to be clickable (focusable I guess). What I have / I'm trying to do: private void mydatagrid

问题 I need to be able to update values of a dataset once a cell loses focus from editing. I know when the cell loses focus (CellEditEnding), but problem is, the actual updating of it's context item does not occur till focus on that row actually occurs. This becomes a huge issue when there is only one item left, since it may never lose focus.

问题 I need to save an string inside a Datagrid Column which differs from the Header. This is needed because I generate a Datagrid dynamically and want to translate the Column Headers while generating them. Then I bind the whole XAML to a ContentControl. No problem till here... But I want to reorder and resize the columns, so I need to lookup them afterwoods. For this I need the original (not translated) ColumnHeader. In my opinion a Tag property of the column would solve this problem, but there
