Hi Tanuj, \
You can use following line of code to validate [user](https://www.mindstick.com/articles/13001/multi-statement-table-valued-user-defined-function-in-sql-server): \

```
private void numericUpDown1_KeyDown(object sender, KeyEventArgs e)    {        if (!(e.KeyData == Keys.Back || e.KeyData == Keys.Delete))            if (numericUpDown1.Text.Length >= 3 || e.KeyValue == 109)            {                e.SuppressKeyPress = true;                e.Handled = true;            }    }I hope it resolve your problem. Please marked as answer if it will resolve your problem.
```
