How to click button when out of focus

I have two Windows forms on a Program.
E.g) MainForm, SubForm
SubForm have a focus and I tried click a button on the MainForm but I had to click twice because of out of focus.
I think MainForm get focus when first click and make click event when second click so I want to making click event pass the "Getting Focus" process.
How can I do?
Sorry for bad english describing.
Thank you.

Can't Focus To Any Control after Closing Dialog

I am showing some database records in a Dialog. When I click any particular record that record fills to Active Form. But I want to focus to a button when my dialog close. So I have written the following code on form closing evennt.
private void frmDG_RecordSelection_FormClosing(object sender, FormClosingEventArgs e)
{
RecordSelectionStatus.Text = "False";
Form TargetForm = Home.ActiveMdiChild;
Button SelectRefConsultant = (Button)TargetForm.Controls.Find("btnSelectRefConsultant_NI", true).SingleOrDefault();
SelectRefConsultant.Focus();
TargetForm.ActiveControl = SelectRefConsultant;
}
But it's not working. Focus still remain to it's previous place. What am I missing ?

I am assuming that the dialog is modal... Instead of doing this in FormClosing do it, after calling ShowDialog(). If not, try using the FormClosed event instead.
I think your code is not working because, while the Form is closing, it still has modal focus.

If frmDG_RecordSelection is also MDIChild, then Home.ActiveMDIChild is this form. That is being closed.
But if frmDG is just a Dialog, the problem is different.
This dialog is Closing. But it's still visible. You cannot set focus to control that is not visible.
So you will have to set focus after this frmDG is completely closed, and invisible... To be more specific, when your MDI form is visible.
It's far more easier to do this from your MDI Form. I don't know how you have programmmed it, but I suppose it's something like that:
//this is in your MDI form
void OnRecordSelected(...)
{
frmDG yourDialog = new frmDG();
frmDG.ShowModal();
frmDG.Dispose();
}
In this case, you will have to set focus after frmDG is disposed.

WinForm closing when 'ok' is selected on messagebox

I have a mainform where you can open another window and change options. One of the options is to copy highlighted text to the clipboard. if the user doesn't highlight text and clicks btnCopy then I want a message to be shown that no text was highlighted. When the user selects 'ok' I want the messagebox to close but I want the 'options' window to stay open.
Right now when the user clicks 'ok' both the message box and 'options' window closes. Why is the 'options' window closing?
Here is my code:
private void btnCopy_Click(object sender, EventArgs e)
{
string copySearch = txtSavedSearches.SelectedText;
if (copySearch == "")
{
DialogResult dialog = MessageBox.Show("You did not select anything to copy. Please select the query to copy.", "Copy search", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else
{
Clipboard.SetText(copySearch);
this.Close();
}
}

You obviously set the DialogResult property of btnCopy to something different than DialogResult.None.
If - in a Form that is not the application's main window - a Button is clicked that has the DialogResult property set (to something different than None), this click causes the Form to close and the calling ShowDialog() method to return that DialogResult.
Find out where you set that property and remove it.
From MSDN (Button.DialogResult):
If the DialogResult for this property is set to anything other than None, and if the parent form was displayed through the ShowDialog method, clicking the button closes the parent form without your having to hook up any events. The form's DialogResult property is then set to the DialogResult of the button when the button is clicked

Why is the 'options' window closing?
The following line will cause the options form to close:
this.Close();
You don't need to do anything to close a MessageBox; it goes away by itself when the user clicks OK, and then your code resumes running from the point where MessageBox.Show was called. MessageBox.Show is a method that returns a value denoting which button the user clicked to get the box to go away (the value varies depending on a) which buttons you chose to show as part of the call to .Show(...) and b) which button the user clicked
Right now when the user clicks 'ok' both the message box and 'options' window closes. Why is the 'options' window closing?
This cannot be, as the message box is shown in the do-if-true part of the IF, and the call to close the options form is called in the ELSE (do if false) part. These two parts cannot run in succession, they must be one or the other. Either your option form closes without a messagebox showing, or a messagebox shows and your form doesn't close
-
Edit:
Renee believes you have set this property:
on your btnCopy button to be something other than None
And then you have also opened your options form like this:
OptionsForm f = new OptionsForm();
f.ShowDialog();
These two things combined will conspire to cause your form options to close any time that btnCopy is clicked (unless the clickevent is canceled)

Show a tooltip on the Close (X) button on the form

I have a form, wherein I prohibit the user from closing it when the user clicks the Close (X) button. Is it possible to show a tooltip on the Close (X) button whenever it is clicked? I want to do it to notify the user why the form would not close.
I thought of a messagebox but then I thought it would be too annoying to close the messagebox every time you click the Close (X) button.
Is there a better way to notify the user, than what I'm trying to do?
EDIT:
This is my code for the FormClosing event
private void InputForm_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.UserClosing)
{
e.Cancel = true;
if (!mCloseReason)
{
e.Cancel = false;
}
}
}
I have a method that will save the inputs in the form. Once that method is finished, I need to automatically close the form. The if-statement will be true once I call this.Close(), this means I can't close the form. That's why I used a variable called mCloseReason to be able to close the form automatically. Now, that's why I was asking if I can notify the user through a tooltip once the Close (X) button is clicked.

I believe the default tooltip for the close(X) button is not editable without some hacking (and it is not practical).
Maybe what you could do is have a status field below your form, so when the user clicks the close button, it says in the status field "cannot close form (...)"
Or another idea is to have a message pop up somewhere on the form and go away after a little, indicating the form cannot be closed.
Another good idea was mentioned by Roger... just have a Close button somewhere on the form with a tooltip coded to it, and hide the forms' title bar?

Reset Focus in Windows 8 Apps

So I have a button that initiates a popup. In the popup I have it to detect when the enter key is pressed when the textbox is in focus and to submit the data and close the popup. However, when I close the popup the button that was pressed to initiate the popup regains focus and receives the key down event and thus opens the prompt again.
So I ask: Is there a way to reset focus from all elements?

You could try this for right after the popup closes.
FirstButton.Focus(Windows.UI.Xaml.FocusState.Unfocused);
Not sure how your code is set up but maybe do something like:
(assuming pop up is within the same window as the original button)
//in the button two clicked function
if (YourPopUp.Visibility == Visibility.Visible)
{
//do data sending
//collapse pop up
FirstButton.Focus(Windows.UI.Xaml.FocusState.Unfocused);
}
