Question

I have a combobox in winforms, which, depending on what you select, determines what’s populated in other comboboxes. I filled the initial combobox using a dataview:

combobox_process.DataSource = dataview
combobox_process.DisplayMember = "UserDefine1"
combobox_process.SelectedIndex = -1

Which works fine, except every one of those lines throws the SelectedIndexChanged event. The function that populates the next combobox listens for that event and so it’s running three times. I asked a coworker and he suggested just looping through the data and adding them all manually as strings, but I’d prefer to stick with databinding if I can. Especially if, in the future, I need to do something that I can only do with databinding.

Any thoughts? Perhaps some way to disable that event during a portion of this code?

Answer 1

You could just unbind your event handler before you make the call and then rebind it when the call is done.
