I have a button column in my grid

When user is pressing the button I would like to get the row number

How can I get it?

You can handle the button's Click event and in there retrieve a reference to the grid's CurrentItem (the button that was clicked will be located in the current item). From there, you can access the grid's Items collection and get the index of the current item using IndexOf.

the problem as I mentioned before is that the current item is null in the button click event 

I also have the same issue my column is below but when handling the Click event the CurrentItem is null as well as SelectedItem. The Items collection CurrentItem is not null but just the first row in the grid.

As long as the grid has a current item before the button is clicked, the CurrentItem property should not be null.

It doesn't so how does clicking the button in the row make the CurrentItem not null?

If the grid does not have a current item when the button is clicked, then the CurrentItem property will be null. This is normal behavior. If you want to have a current item, then you will need to set the CurrentItem property or click on an item in the grid to make it current.

Surely that goes against the point of a button in a column. When you click a button on row 5 you expect the CurrentItem to be set to row 5. Is there anyway to enforce that behaviour?

 

Thanks

Not if the focus is caught by the button first. If the focus never reaches the grid, then the current item cannot "automatically" be set. You could always set the current item yourself programatically in the button's Click event.

How do I know what to set the CurrentItem to?

There are several ways to get to data item for a Row or Cell... But the simplest is to use the Row's DataContext (or Cell`s).

myDataGridControl.CurrentItem = myRow.DataContext;

How do I find the cell or row the button is in?
