Found a graduation. Net work, haven't learned before, access to the DataGridView recently and a lot of things can't figure out
Now do DataGridView by way of the data binding to fill in the data, if I give the first line of the Tag assignment, and then the background changed the data table, then to reload DataGridView data, the first line of the data is changed, so now is still the first line of the Tag binding, have nothing to do with the data? Also does not automatically remove?
I want to give new rows of data to assign a value to distinguish, the Tag and then submitted to the backstage after reload the table data, load after removed the Tag, how should do,
I didn't touch the Tag itself still feeling clear, hope somebody can explain,
