Convert DataGrid Contents to DataTable
Extracting the contents of a UI DataGridView produces a single Text variable containing all the data in a specific format. This Process converts this Text format into a DataTable, which can be used for easier access and manipulation of the data.
Note that it is quite possible for the format to be different, depending on the application which contains the DataGridView - therefore, some tweaks may be necessary in order for this Process to function properly in every scenario.
da = new DataAdapter();
dt = new DataTable();
dt.Locale = System.Globalization.CultureInfo.InvariantCulture;
BindingSource bs = new BindingSource();
bs.DataSource = dt;
dataGridView.DataSource = bs; for more information you can refer data grid content
