how can I get the single row in a datagrid when click on it

[UESTC]

I use datagrid.CurrentRowIndex, but this value
can not be mapped to the datasource.
How to get the rowindex of the datasource when
clicked the datagrid? thanks.

You can try using the Position property of the CurrencyManager object.

CurrencyManager cm = (CurrencyManager) this.BindingContext[this.dataGrid1.DataSource, this.DataGrid1.DataMember];
int index = cm.Position;
