将一行从网格视图传递到另一个网格视图asp.net C＃

Question

I am wondering of how to pass data, that's one row from Grid View1 to Grid View2 in the same Web form!I created two tables, the first one contains four columns and contains records: Id, name, address and age. I also created the second form which also contains four columns: Id, name, address and age, but left empty for purpose of transmitting data from the first table. I wonder if it is possible if to select one row from Grid view1 and then click a button which enables to pass that selected row to Grid View2 !? One row each a time added after hitting the send button to the second grid view and guarantees that data added to the second table!

Any ideas of how to do that would be much appreciated.

I'll give you an overview of some steps you might want to take

I assume you use a DataSet or a DataTable where your records are stored in.

• use the eventHandler of the gridview, like CellClick , most of them have a e.RowIndex value, which you can use to get the index of the row that is selected

Like this:

    private void dg1_CellClick(object sender, DataGridViewCellEventArgs e)
    {
            selectedIndex = e.RowIndex;
    }

• use that index to get the id from that record, so you know what data you are talking about

like this:

int id = Convert.ToInt32(dataset1.Tables[0].Rows[selectedIndex][0]);

then just find the row by id or use the knowledge above to combine this

DataRow row = dataset1.Tables[0].Rows.Find(Id);
dg2.Rows.Add(row);

it's better to use datasets and give the datagridview a datasource to that dataset, not sure what your intentions are

• you could also get the id from the row you selected, based on that you call another sqlCommand to get that current row, a good way if you have more data you want to load from the database that rely on that id
