如果gridview的行验证失败，如何丢弃行（devexpress）

Question

In XtraGridView, from the way RowValidation works, it seems that user has no choice but first correct the values (leading to validation being successful) and then press Discard button (which I provided separately and it does RejectChanges). I want an option that user can discard the row without any pop-up alert even if row has invalid data.

In my case when user presses Discard, it leads to row validation being fired (due to focus change). The discard button event handler is suppressed, if row validation is unsuccessful. This way I am never able to simply discard the invalid row.

This is common feature anyone with a grid would need. Expecting a standard solution or a workaround.

Answer 1

You made me curious, as you say,something as basic as that should be in there somewhere.

Bit of gooling found that waht you do is trap the InvalidRowException, it has a var argument and you can set it to ignore.

Here's where I found it.

DevExpress

Answer 2

Can't you check the focused button and sidestep validation if the discard button is focused.

The general DevExpress setup forces the user to insert valid values when validating, pressing Esc is a simple solution to reset the field to the original value.
