Validate user input
I want to validate user input. As an example, on an ma crossover, the user enters a 5 for the long trend and a 20 for the short trend. The entries have been reversed.

Hello dukeb,
You can do the validation in the setter of the property. A sample code will be like
[Description("Period for slow MA")]
Code:[GridCategory("Parameters")] public int Slow { get { return slow; } set { slow = Math.Max(1, value); if (fast > slow) //fast is the other property { System.Windows.Forms.MessageBox.Show("Fast cannot be greater than Slow"); //do some other stuffs } } }
