Form Reload

Question

Hello everyone I have created a MultiDocument application. One that has one main form and a few child forms. What I am trying to do is that since these child forms access a database I need to keep them updated. I already have the main parent form using a timer and polling the database for changes. When a change is detected I need to reload the forms. How can I reload a child form. Using the refresh method only redraws the form I need to reload the form so that the method that update the data on the form is executed. Anyone have any suggestions on how to accomplish this?????? Thanks Kendal

I have solved my problem. I created my own form class that inherits from Windows.Forms.Form class and added my own virtual method. Every form I create that must be updated uses my own form class and I call it. Thanks to all for all of the assistance Kendal

One of the problems is that the parent form does not create every one of it's child forms. A child for will also create a form with the parent set to it's parent. I hope I didn't lose you. Basically the parent form does not instantiate every one of it's child forms. Ideally I would use a foreach(Form f in this.MdiChildren) to cycle through each form and execute a reload method. If you would give me a little more description on the the method you were talking about. All suggestions are appreciated. Thanks Kendal

As Mahesh Suggested is not it possible to maintain a flagging in your parent form which child form it has been opened. So that when u can refresh do the samething again. I mean call the funtionality again.

I can't do that in this instance. The parent form does not know exactly which forms are open in order to call the form specific method that loads the information. The methods that load the data are different for each form. I was hoping that there was a Form.Reload() method or some way to duplicate that. I can actually start a seperate timer for each form that is loaded but I was hoping to be more efficient by using one timer in my parent form that will reload every child form when data has changed. Any suggestions???? Thanks Kendal

Wherever you are refreshing the form also reload the data by calling the method which binds the data to the data bound controls.
