How to Access, Control Datagridview of external winform app?

Hello,
I have a .net winform app with 1 form and 1 dgv control.
I searched and found some ways like windows api and ui automation stuff but i could not find more details to perform above actions especially with datagridview control example.

Can someone kindly suggest or share some starting points so that i can move ahead? Im badly stuck with this requirement for days....

What i need is a way to access that datagridview and manipulate the data from another winform app in few ways like:

1. copy/paste single or multiple rows
2. edit data/rows
3. right click on a row

I searched and found some ways like windows api and ui automation stuff but i could not find more details or any example to perform above actions especially with datagridview control.

Can someone kindly suggest or share some starting points so that i can move ahead? Im badly stuck with this requirement for days....

Thanks....

1. For copy single/multiple row you can simple create a datatable and store data to that datatable and later use it.

For example

private void dgvGrid_KeyDown(object sender, KeyEventArgs e)
{
if (e.Control == true && e.KeyCode == Keys.C)
{
DataTable dt = ((DataTable)dgvGrid.DataSource).Clone();
foreach (DataGridViewRow row in dgvGrid.SelectedRows)
{
dt.ImportRow(((DataTable)dgvGrid.DataSource).Rows[row.Index]);
}
dt.AcceptChanges();
}
}

2. For edit row you can use geidview CellEndEdit event

private void dgvGrid_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
if(e.RowIndex >= 1)
{
if (e.ColumnIndex >= 1)
{
// Do Your Coding...
}
}
}

For right click on a grid view row add a ContextMenuStrip control to the form. Then add a menuitem "toolStripMenuItem1" to the ContextMenuStrip, set the text property "Delete". Then add below coding to datagridview CellMouseUp event.

private void dgvGrid_CellMouseUp(object sender, DataGridViewCellMouseEventArgs e)
{
if (e.RowIndex >= 0)
{
if (e.Button == MouseButtons.Right)
{
ContextMenuStrip1.Show(Cursor.Position);
}
}
}

Then on toolStripMenuItem1_Click event do your coding.
