Preserve DataGridViewRow.Tag property in databound DGV when sorting data

Is there a way to keep the tags from being nulled as soon as I sort the grid?

If not, is the Tag property actually useful for anything excep开发者_开发百科t non-databound usage?

Based on you last question, you are setting the Tag of DataGridViewRow objects. And they might very well be re-created during a Sort operation. Use reflector to make sure, but I would start looking for a workaround.

In general, the Tag property is a last resort.

You could use a Dictionary<object, object> to couple your data to the dgvr.DataBoundItem as key.
