I have a web part containing a repeater control which display the announcements. I want to make a custom tool part which enables a user to limit the number of rows of repeater. I have created a text box that takes the number of news to display as an input. Now I am confused that how do I bind its event with the 'Ok' button i.e. when the button is pressed the code should render the input and make the repeater accordingly. Here is my code:
[WebBrowsable(true),
        WebDisplayName("Number of announcement to display"),
        WebDescription("Controls number of announcement"),
        Category("Content Control"),
        Personalizable(PersonalizationScope.Shared)]
        public int NumberofAnnouncement
        {
            get;
            set;
        } 
How do I bind the event ? I need some assistance.
