move datagridview Row to another datagridView

问题

I've gone through the other answers for this kind of question, nothing has really worked well so far.

I have a foreach loop that should add the the row from the source datagridview to the destination datagridview then remove that row from the source.

The invalid operation exception is: Row provided already belongs to a DataGridView control.

I couldn't get ...Rows.Copy() to work either. Any ideas?

foreach (DataGridViewRow selRow in fromDataGridView.SelectedRows)
{
    toDataGridView.Rows.Add(selRow);
    fromDataGridView.Rows.Remove(selRow);
}

回答1:

You need to remove the row from fromDataGridView before you add it to toDataGridView.

But you're modifying the collection inside the foreach loop - that won't work.

The workaround is to copy the collection for use in the foreach.

Try this:

foreach (DataGridViewRow selRow in fromDataGridView.SelectedRows.OfType<DataGridViewRow>().ToArray())
{
    fromDataGridView.Rows.Remove(selRow);
    toDataGridView.Rows.Add(selRow);
}

Here is an example of what you could do or try..

its happening when one row is removed the rows count decrements too so if you put your code in for loop and run it in reverse it would work fine have a look:

for (int selRow = dataGridView1.Rows.Count -1; selRow >= 0 ; selRow--)
{
   toDataGridView.Rows.Add(selRow);
   fromDataGridView.Rows.Remove(selRow);     
}

Adding a new row directly to DataGridView is not possible when there is BindingSource.

You should add row to the BindingSource of second view and let it to add the row to its grid.

I've tested the below code in a working solution.

var selectedRows = dataGridView1.SelectedRows;
int count = dataGridView1.SelectedRows.Count;
for (int i = 0; i < count; i++)
{
    bindingSource2.Add(bindingSource1[selectedRows[i].Index]);
    dataGridView1.Rows.Remove(selectedRows[i]);
}
