One solution to this is not to handle the button-click event in the search form, but in your first dialogue.
This is one reason that I suggested the public DataGridViewRow SelectedRow property in my previous post.
In your Search dialogue:
public event EventHandler LoadButtonClick
{
add
{
this.loadButton.Click += value;
}
remove
{
this.loadButton.Click -= value;
}
}
doing it this way keeps to OOP principles. Of course if you want to 'cheat' just change the Modifier property for the button, in the properties window, to public.
You will have to declare a reference to the Search dialogue as a field of the first dialogue:
public class FirstDialog : Form
{
private SearchDialog sd = null;
........
........
........
........
Then in the first dialogue, where you create the search dialogue, something like:
using (sd = new SearchDialog())
{
sd.LoadButtonClick += MyLoadButtonClickHandler;
if (sd.ShowDialog() == DialogResult.OK)
{
sd.LoadButtonClick -= MyLoadButtonClickHandler;
}
else
{
sd.LoadButtonClick -= MyLoadButtonClickHandler;
}
}
The click handler can then do
private void MyLoadButtonClickHandler(object sender, EventArgs e)
{
this.UserNameTextBox.Text = sd.SelectedRow.Cells["UserName"].Value.ToString();
etc.
}
Hope this gives you some ideas.

Hi Guys,
I am working on a Windows Form where I have placed a Button control (Button text: Exit). In the Button1_Click event Handler, I have added this code:
//Code begins here
private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("Are you sure to exit the application! Selct Ok to Exit now or Cancel to stay in the current form", "Sample App", MessageBoxButtons.OKCancel, MessageBoxIcon.Exclamation);
if (MessageBox.Show("Are you sure to exit the application! Selct Ok to Exit now or Cancel to stay in the current form", "Sample App", MessageBoxButtons.OKCancel, MessageBoxIcon.Exclamation) == DialogResult.OK)
{
Close();
}
else
{
return;
}
}
//Code ends here
However, when I debug the solution and click on the Exit button, the Message Box is displayed asking for confirmation. Then, when I click on the Ok button, instead of closing the application, the same Message Box pops up again! Then, again I have to click on Ok and this time the Click Event executtes and the application closes. Similar is the case with the Cancel Button. Why does the MessageBox display the same message twice? Help me Please....
Your help will be appreciated. Thanx....

youve now posted te same question again a mere 10 minutes later.
READ THE CODE. STEP THROUGH THE CODE. IT IS OBVIOUS WHY YOU GET TWO MESSAGE BOXES.
I thought you might be hard-of-reading so i shouted that in the typical englishman manner of just talking louder and slower to foreigners in english.

You're kidding, right? You've had so many hints already that if you cant work it out now its time to hand back your textbooks, cancel your account with your college computer centre, and go get a job flipping burgers.

I think, as with many posts on here, that certain phrases get lost in translation.
Obviously the guy is a beginner coder, possibly a beginner in English too

By the way its quite obvious moron. Read your (???) code 
|

Clearly, you didn't do a very good job of it. You should have separated the letters with spaces l i k e t h i s to mimic the effect of talking slower.

You're right. very good point.

Raj check the answer which is already given....
BTW why did you delete the previous post and re-posted the same content here...????
Have a Happy Coding.....

Sorry for deleting the previous post,
there was a mistake in it. Instead of writing
Button1_Click, I wrote Button3_Click. It wouldn't have affected the
program too much, but I did so, to make u people understand the code better such that it doesn't affect the main motive of the program.
plz help

You seem to read every message except the ones that give you the solution. Did you even try what 8kelvin suggested below?

In the interest of killing this question I will now provide you with the answer. Ready? Concentrate now...
you have told the computer to show you two message boxes.. look...
MessageBox.Show("Are you sure to exit the application! Selct Ok to Exit now or Cancel to stay in the current form", "Sample App", MessageBoxButtons.OKCancel, MessageBoxIcon.Exclamation);
if (MessageBox.Show("Are you sure to exit the application! Selct Ok to Exit now or Cancel to stay in the current form", "Sample App", MessageBoxButtons.OKCancel, MessageBoxIcon.Exclamation) == DialogResult.OK)
The first one you show the message box and discard the user's response.
The second one is within an if(..) construct. This does a boolean check on the contents of the (..) and if that returns true then the code directly after fires. Otherwise the code inside the else part executes. You would have learnty this had you have sat in on lecture "programming 101".
Your if(..) checks that the users response is equal to DialogResult.OK (or, more simply the user clicks trhe OK button) and if they do then the app closes. The part in your else is irrelevant.
Good luck with the rest of your career, mine'll be a big mac with fries please.

I think he might not be able to do this as well... you're probably end up with 2 chicken burger's instead!

ignore those jokers....
its because you need to put in another MessageBox.Show to handle the cancel button. if you dont then windows will auto create another one to make up for it... try the following...
private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("Are you sure to exit the application! Selct Ok to Exit now or Cancel to stay in the current form", "Sample App", MessageBoxButtons.OKCancel, MessageBoxIcon.Exclamation);
if (MessageBox.Show("Are you sure to exit the application! Selct Ok to Exit now or Cancel to stay in the current form", "Sample App", MessageBoxButtons.OKCancel, MessageBoxIcon.Exclamation) == DialogResult.OK && MessageBox.Show("Are you sure to exit the application! Selct Ok to Exit now or Cancel to stay in the current form", "Sample App", MessageBoxButtons.OKCancel, MessageBoxIcon.Exclamation) == DialogResult.Cancel)
{
Close();
}
else
{
return;
}
}
