Selected Checkbox...

[gonad]

Hi. i have a few checkboxes on my form and i want to show a simple messagebox when one of those checkboxes are checked. how can i do this dynamically? for instance, instead of writing an if statement per checkbox, like this: if(checkbox1.checked = true) { MessageBox.Show("checked"); } write it dynamically, like this: (the is the name of the selected checkbox) if(.checked = true) { MessageBox.Show("checked"); } i know this is pretty easy for all you guru friends out there. :) Thanks, .gonad.

I'm not sure if I understand you, but you can maybe use first parameter of your event handler method (sender). You have to set same function as event handler for all checkboxes.

private void checkBox1\_CheckedChanged(object sender, System.EventArgs e)
{
  CheckBox checked=(CheckBox)sender;
  // checked is checkbox that was just checked/unchecked

}

Hi. Thanks for your help. this worked exactly as you said, but i do have a queston. Can you explain what the (CheckBox)sender is specifying? also, can i use this for a textbox, or other controls, as well? for example, TextBox tb = (TextBox)sender; I'm new at this stuff, can't you tell? Thanks again. .gonad.

First parameter (sender) of event handler is affected object. it is passed as object so you need to cast it to correct type (Button / CheckBox etc..). So when you have event handler for Button, sender is button user clicked on. If you have event handler for TextBox, sender is this TextBox. i'm only pointer to myself
