Question

How we can copy one or more than one rows from a data grid view to other data grid view on same form. Here, I’ve searching option which search from the first grid and if found some matching rows then copy them to 2nd grid. How I can achieve this ?

Answer 1

You can do something like this:

ConvertGridToTable();  // Add data in Datatabledt from gridview
Clipboard.Clear();
DataObject data = new DataObject(DataFormats.Serializable, Datatabledt);
MessageBox.Show("Data Copied.");
Clipboard.SetDataObject(data);

Now the Datatabledt is available in Clipboard which you can paste in the second gridview which you can do with this:

DataObject data = (DataObject)Clipboard.GetDataObject();
DataTable dt = (DataTable)data.GetData(DataFormats.Serializable);

foreach (DataRow dr in dt.Rows)
{
    dtData.ImportRow(dr);
}
dtData.AcceptChanges();
grdProgramData.DataSource = dtData;
MessageBox.Show("Data Pasted.");

EDIT:

For one or more rows you can achieve that with looping through selected rows.

EDIT

This is the content in ConvertGridToTable

private void ConvertGridToTable()
{

    if (Datatabledt.Rows.Count > 0)
    { }

    Datatabledt = dtData.Clone();

    foreach (DataGridViewRow gr in YOURGRIDVIEW.SelectedRows)
    {
        DataRow dc = Datatabledt.NewRow();
        dc["KEY-FIELD"] = Int32.Parse(gr.Cells[0].Value.ToString());
        .....

        Datatabledt.Rows.Add(dc);
    }
    Datatabledt.AcceptChanges();
}
