How to declare an event

Hi all,

as I am not an experienced programmer, I have a doubt about how to declare an event on my code.

I have a dataGridView that has to activate a method each time a value in a column is changed.

I know the method to make it happens is this one below:

private void dgrid_CellValueChanged(object sender, ataGridViewCellEventArgs e)<br /> { ... }

But, even after including this method in my class it doesn't work!

Do I have to do something else? Do I have to declare anything somewhere else ( I mean, something to call this method when the event happens )?

If yes, how do I do it and where do I do it?

Thanks in advance! :)

Maybe this is what you need. Put it on the form Load event.

C#

this.dgrid.CellValueChanged += new System.Windows.Forms.DataGridViewCellEventHandler(this.dgrid_CellValueChanged);

Yes, you have to subscribe to that event: subscribe to the event[^]

In your form's constructor, you could add,

dgrid.CellValueChanged += new DataGridViewCellEventHandler(dgrid_CellValueChanged);

Also, if you're using Visual Studio, in the Design View of your form/window, go to the Properties tab, switch to "Events" (instead of properties) and double click on the event you need. And all the wiring up of events will automatically be done for you.
