限制NumericUpDown值，具体取决于从DataGridView中选择的值

Question

How can I limit max int that can be entered into my NumericUpDown (nudqty). my code works it limits the value when I change it using up down arrows, but when I type it's not. suggestions please and tell me if it's not possible in NumericUpDown and just change it to TextBox .

private void dgv1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    lblqty.Text = dgv1.SelectedRows[0].Cells[5].Value.ToString();
    nudqty.Maximum = Convert.ToDecimal(lblqty.Text); 
}

Answer 1

Set SelectionMode of DataGridView to FullRowSelect and then handle SelectionChanged event of DataGridView . In the event after finding the value using CurrentRow , reset the Value of NumericUpDown to 0 and set its Maximum to the extracted value:

private void dataGridView1_SelectionChanged(object sender, EventArgs e)
{
    int max = (int)this.dataGridView1.CurrentRow.Cells[5].Value;
    this.numericUpDown1.Value = 0;
    this.numericUpDown1.Maximum = max;
}
