WPF Binding: Triggering a command from another method base u

Question

At the moment, my databinding working base upon the delegate command when buttonColor

is clicked. However, I want to now disable the buttonColor base upon datagrid.

So if the there are no rows in the datagrid which is databind to a datasource,

disable the buttonColor. If there are rows in the datagrid, Enable the button. Can

someone assist me. I almost have the concept of the MVVM and databinding, just need

somemore experience through a lot of small examples.

private Boolean enableColor { get; set; }

private Delegate isColorEnable { get; set; }

Delegate IsColorEnableCommand { get { return isColorEnable ?? (isColorEnable = new Delegate(IsColorEnableCommandMethod, CanColorBeEnableFromModel)); }set { isColorEnable = value; }}

private void IsColorEnableCommandMethod(){ Do Something}

private void CanColorBeEnableFromModel(Object obj){ Boolean isEnable = (Boolean)obj; return isEnable; }
