MDI Child form events .... could not be raised :(

[CJack]

hy,
I have an mdi application, i create a child form and I want to know
when a button is pressed while that child form is loaded.
I have this code:

private void frmTestBaby_KeyUp(object sender, System.EventArgs e)
{
MessageBox.Show("keyboard button pressed!");
}
Following is the code to load the frmTestBaby

private void menuItem2_Click(object sender, System.EventArgs e)
{
frmTBaby frmTestBaby = new frmTBaby();
frmTestBaby.MdiParent = this;
frmTestBaby.Show();
}

Can someone help out to how to get the event raised KeyUp for the
child form frmTestBaby.
Please note that I have also tried activating the child form after
frmTestBaby.Show(); but it did not work.

regards

Hi,

If I understand you correctly, you want to raise an event
from the child form so the parent form can receive the
event. If that's what you want, here's what you can try.

1. Add the event handler to the frmTestParent form:

private void menuItem2_Click(object sender,
System.EventArgs e)
{
frmTBaby frmTestBaby = new frmTBaby();
frmTestBaby.MdiParent = this;
frmTestBaby.Show();

frmTestBaby.KeyUp += new
System.Windows.Forms.KeyEventHandler
(this.frmTestBaby_KeyUp);
}

2. Add the code to the frmTestParent form to handle the
event.

private void frmTestBaby_KeyUp(object sender,
System.Windows.Forms.KeyEventArgs e)
{
MessageBox("Event Receive from Parent: KeyUp was "
e.KeyCode);
}

This will only work if the frmTestBaby form does not have
a control (ie: text box) that will receive the KeyUp
event before the form. Otherwise, the control has to
raise the event so the form will receive it.

Hope this helps,
Thomas

You have to make sure the controls inside frmTestBaby
form do not receive the KeyUp event first. This may not
be possible. Also, clicking on the button does not raise
a KeyUp event.

I read your original question again. If you just want
the parent to receive an event when the child form is
loaded, you should have the parent capture the
frmTestBaby.Load event instead of the KeyUp event.

Try the following code:

private void menuItem2_Click(object sender,
System.EventArgs e)
{
frmTBaby frmTestBaby = new frmTBaby();
frmTestBaby.Load += new System.EventHandler
(this.frmTestBaby_Load);
frmTestBaby.MdiParent = this;
frmTestBaby.Show();
}

private void frmTestBaby_Load(object sender,
System.EventArgs e)
{
MessageBox.Show("child form loaded");
}

Please let me know if I've misunderstood your question
again. I hope this will point you to the right path.

Hi Arif,

Sorry, I totally misunderstood what you were trying to
do. All you wanted to do was to detect a KeyUp event in
the frmBabyTest whenever a key is pressed on any controls
inside the frmBabyTest form, correct?

As I mentioned in my first response, the controls inside
the frmBabyTest form will receive the KeyUp event first.
As a result, the frmBabyTest never receives it.
Therefore, the control, that receives the KeyUp event,
needs to raise it to the frmBabyTest form.

For example:

private void TextBox1_KeyUp(object sender,
System.Windows.Forms.KeyEventArgs e)
{
MessageBox.Show("From TextBox1_KeyUp");
this.OnKeyUp(e); // Raise the onKeyUp event
}

private void frmBabyTest_KeyUp(object sender,
System.Windows.Forms.KeyEventArgs e)
{
MessageBox.Show("from frmBabyTest_KeyUp");
}

Don't forget to add this to the InitializeComponent() or
frmBabyTest constructor:

this.KeyUp += new System.Windows.Forms.KeyEventHandler
(this. frmBabyTest_KeyUp);

This will work. I tested it out on my test MDI app.

hy Thomas, I think that I could not communicate well. I neeed to raise
KeyUp event OF the CHILD Form. For example if the child form name is
frmBaby then I need to have some action on
frmBaby_KeyUp(object sender, System.Windows.Forms.KeyEventArgs e)
{
MessageBox.Show("Key up on child form frmBaby");
}
I DO NOT want to raise events on the controls of child form now.
can you tell me how to do this? or can you guide me if i could find
some documents detailing this or in worse case if C# is able to handle
child form events?

i hope you know what i mean.

Hi Arif,

I understand that's what you want. The last sample does
exactly what you want. You need to understand that if
your frmBaby has any controls (which it does), the
controls will receive the KeyUp event first if any are in
focus. Therefore your frmBaby never receive the event.
That's why each of your controls need to raise the KeyUp
event (frmBaby.KeyUp(e)) so the frmBaby will receive it.

You mentioned earlier that the click event works fine.
That's because you can click on an area of the form where
no controls are located. As a result, the frmBaby
receives the onclick event first instead of any controls.

Here's a test you can do. Remove all of your controls or
disable all of them in the frmBaby. Then capture the
KeyUp event in the frmBaby, you'll find out that it will
work without raising a KeyUp event from any controls.

Hope this will clarify the issue!
Thomas

Thank you very much Thomas. Its working now.

Hi Arif,

I understand that's what you want. The last sample does
exactly what you want. You need to understand that if
your frmBaby has any controls (which it does), the
controls will receive the KeyUp event first if any are in
focus. Therefore your frmBaby never receive the event.
That's why each of your controls need to raise the KeyUp
event (frmBaby.KeyUp(e)) so the frmBaby will receive it.

You mentioned earlier that the click event works fine.
That's because you can click on an area of the form where
no controls are located. As a result, the frmBaby
receives the onclick event first instead of any controls.

Here's a test you can do. Remove all of your controls or
disable all of them in the frmBaby. Then capture the
KeyUp event in the frmBaby, you'll find out that it will
work without raising a KeyUp event from any controls.

Hope this will clarify the issue!
Thomas

hy Thomas, I think that I could not communicate well. I

neeed to raise

KeyUp event OF the CHILD Form. For example if the child

form name is

frmBaby then I need to have some action on
frmBaby_KeyUp(object sender,

System.Windows.Forms.KeyEventArgs e)

{
MessageBox.Show("Key up on child form frmBaby");
}
I DO NOT want to raise events on the controls of child

form now.

can you tell me how to do this? or can you guide me if i

could find

some documents detailing this or in worse case if C# is

able to handle

child form events?

i hope you know what i mean.
regards

Hi Arif,

Sorry, I totally misunderstood what you were trying to
do. All you wanted to do was to detect a KeyUp event in the frmBabyTest whenever a key is pressed on any controls inside the frmBabyTest form, correct?

As I mentioned in my first response, the controls inside the frmBabyTest form will receive the KeyUp event first. As a result, the frmBabyTest never receives it.
Therefore, the control, that receives the KeyUp event,
needs to raise it to the frmBabyTest form.

For example:

private void TextBox1_KeyUp(object sender,
System.Windows.Forms.KeyEventArgs e)
{
MessageBox.Show("From TextBox1_KeyUp");
this.OnKeyUp(e); // Raise the onKeyUp event
}

private void frmBabyTest_KeyUp(object sender,
System.Windows.Forms.KeyEventArgs e)
{
MessageBox.Show("from frmBabyTest_KeyUp");
}

Don't forget to add this to the InitializeComponent() or frmBabyTest constructor:

this.KeyUp += new System.Windows.Forms.KeyEventHandler
(this. frmBabyTest_KeyUp);

This will work. I tested it out on my test MDI app.
Thomas
