Get name of control in groupbox//get name of control and associated groupbox

Hi all,

First here is my Code.

C#

private void Form1_Load(object sender, EventArgs e)
{
    foreach (var button in Controls.OfType<System.Windows.Forms.Control>())
    {
        button.Click += button_Click;

    }

}

    private void button_Click(object sender , EventArgs e)
    {
        Console.WriteLine("the Control with the name "+ this.Controls[((System.Windows.Forms.Control)(sender)).Name].Name+ "was clicked");

    }

Every Control in the Control Class print its name if it was clicked.

This works fine but when a Control e.g. a button or pictureBox is in a GroupBox it doesnt give me the name anymore if i click on it. When i click on the Groupbox itself, it gives me the name of the GroupBox. It seems that i have no access to the Controls names anymore.

Actually my question is about how can i get the name of the clicked Control and the associated GroupBox if the Controls are in a GroupBox. I wanted to mention that problem anyway.

I need it in the same way like the code above. I dont want to implement for every Control a seperate Method.

I would highly appreciate it if somebody can give me a suggestion.

Thank you.

What I have tried:

Google, MSDN, looking about common issues at CodeProject.com

GroupBox has its own controls collection. You would need to check it instead of the forms controls collection.

Solution 1

This is because the controls in a container such as a groupbox or panel belong to the container's controls collection, not the form's control's collection. You need to recurse through the container's collections if you want to get them all

C#

private void SetClickHandler(Control.ControlCollection controls) {
	foreach (var button in controls.OfType<Control>()) {
		button.Click += button_Click;
		if (button.Controls.Count > 0)
			SetClickHandler(button.Controls);
	}
}
private void Form1_Load(object sender, EventArgs e) {
	SetClickHandler(Controls);
}

Hi,

thank you very much for your answers.

To Midi_Mick:
I replaced your code with my code, but it is still giving me only the names of the controls outside the groupbox/panel. Do you have an idea what it could be?

Thank you.

Midi_Mick 9-Nov-16 17:11pm

Did you do what I did first up, and in the foreach, forget to change "Controls.OfType" to "control.Controls.OfType"? Or perhaps the braces around the outside of the button.Click+= and the if statement?

@Mick:
Perhaps you should not ask for ContainerControl - better you ask if the ControlsCollection of this Control has a Count-Value > 0. Also the type for the SetClickHandler-method could be Control instead of ContainerControl ...

Midi_Mick 10-Nov-16 4:32am

You are right. GroupBox doesn't inherit from ContainerControl. Who'd have thunk. Will update my solution to suit. Thank you.

You are welcome ...

Hey cool,

now it is showing me the name of the clicked button which is in the groupbox. Thanks a lot for that.

Now how can i get the name of the groupbox which contains the button? Actually i want both at the same click. I would like to have a print like: "You clicked at the button_X in the groupbox_Y" , when i click on button_X. I think its a parent issue, but cant figure it out myself :(

Thanks a lot for helping me.

Yes - in the click event, just check the ((Control)sender).Parent property. That will be whatever control contains the control that was clicked, so you can get ((Control)sender).Parent.Name, or whatever. Note, for controls that are directly on the form, this will be the form itself - you might want to check for that.

Member 12341536 10-Nov-16 7:48am

Thanks a lot it works.
Appreciate it very much.

Member 12341536 10-Nov-16 11:26am
