I'm trying to delete the line in which it has the focus of a datagrid , I've used the following code:
datagrid.Rows.RemoveAt(e.RowIndex);
You are returning the following message:
Uncommitted new row can not be deleted.
What's wrong? Can anyone help me?
You must set the property AllowUserToAddRows from DataGridView to false .
And to avoid an exception OutOfRangeException , first check if the line index is valid.
var indice = e.RowIndex;
if (indice >= 0) {
var linha = dataGridView1.Rows[indice];
if (!linha.IsNewRow)
dataGridView1.Rows.Remove(linha);
}
You can do this:
private void btoDeleletarItem_Click(object sender, EventArgs e)
{
datagrid.Rows.RemoveAt(datagrid.CurrentRow.Index);
}
This way you are deleting from the DataGrid just the row that is selected in the Grid table. Remember that it is a good thing to check the SelectionMode option for FullRowSelect , so that when a row cell is selected by the user or you the entire row is checked. >
Try this:
if (dgvItens.CurrentRow != null)
{
listaItens.RemoveAt(dgvItens.CurrentRow.Index);
dgvItens.DataSource = listaItens.ToList();
}
