Chart won't evaluate Tooltip as String

I want use my tooltip text as string.
When i try this MessageBox.Show(chart1.Series["Series1"].LegendToolTip); ===> Output: #MIN-#MAX
MessageBox.Show(chart1.Series["Series1"].LegendToolTip.toString()); ===> Output: #MIN-#MAX
i want output string is "1-49".

I don't think you can let the chart evaluate the ToolTip without the respective mouse actions.
But similar to Marton's suggestion you can evaluate the ToolTip formula yourself, maybe like this:
Series S1 = chart1.Series["Series1"];
string legendToolTip = S1.Points.FindMinByValue("Y1").YValues[0] +
" - " + S1.Points.FindMaxByValue("Y1").YValues[0] ;
MessageBox.Show(legendToolTip );

Using Windows forms c# message box

How will I get a messagebox "Or another way of doing this" to have multiple lines?
I've got a messageBox to appear when the user presses F1 and I need it to have a sort of list:
Product Name = Alphanumeric + Special Characters.
Quantity = Maximum 100.
Price = Must be Numeric.
Etc
Thanks.

You can use \r\n or Environment.NewLine at the end of each line to be shown or you can use the StringBuilder class:
var message = new StringBuilder();
message.AppendLine("Product Name = Alphanumeric + Special Characters.");
message.AppendLine("Quantity = Maximum 100.");
message.AppendLine("Price = Must be Numeric.");
MessageBox.Show(message.ToString());

Add/concatenate Environment.Newline to your string.

Put "\r\n" at the end of each line of the message.
so, for example:
var message = "Product Name = MyProduct.\r\n";
message += "Quantity = Maximum 100.\r\n";
message += "Price = Must be Numeric.\r\n";
MessageBox.Show(message);

Just use Environment.NewLine where you want a newline to appear. For example:
string message = "Line 1" + Environment.NewLine + "Line 2";
MessageBox.Show(message);
This will output:
Line 1
Line 2

adding space in texbox results when sending thru email

wassup guys im new to C# coding and i did a search but couldn't find exactly what im looking for. So i have a couple of text-boxes which holds string elements and integers
what i want to do is when these boxes are filled in i want to send a summary of the email to client/customer but the format is whats getting me.
(first, one) are strings equaling different text-boxes
my code is:
emailCompseTask.Body = first + one + Enviroment.NewLine +
second + two + Enviroment.NewLine
and so on problem is which i send thru email it shows something like this:
computer service25.00
instead of:
computer service 25.00
is there a way to add spacing to make this more presentable? or even a better way perhaps thanks in advance guys

try this :
emailCompseTask.Body = first + one + " "+ second + two ;
body takes as HTML input, check here for more spacing option.

I'm a bit confused, but you just want to add some spacing in the output? Just throw some spaces in there like you would another variable.
first + " " + one + Environment.NewLine
+ second + " " + two + Environment.NewLine;

You can use a table
string tableRow = #"<tr>
<td>{0}</td>
<td>{1}</td>
</tr>";
string htmlTable = #"<table>
{0}
</table>";
string rows = "";
// Can do this in a loop
rows += string.Format(tableRow, first, one);
rows += string.Format(tableRow, first, one);
emailComseTask.Body = string.Format(htmlTable, rows);

how to print the string in next line in wpf

Window.Content = "Chandru" + "Guna" + "Kalai";
when i run this program the result like this ChandruGunaKalai.
so i want to print the each string value in line by line.
like this
Chandru
Guna
Kalai
please help me

Window.Content = "Chandru"+Environment.NewLine + "Guna" +Environment.NewLine+ "Kalai"+Environment.NewLine;

Environment.NewLine
Window.Content = "Chandru" + Environment.NewLine + "Guna" + Environment.NewLine + "Kalai";
That how to print a new line. Or you can use a StackPanel and set the Orientation to Vertical and put 3 seperate TextBlocks in it.

How to Show New Line command in text box?

Hi i am doing a small project in C#, and i need to know what commands are comming from input source so i can do my work accordingly..
here is example...
textBox1.Text = "First line \nSecond line";
richTextBox1.Text = "First line \nSecond line";
Richtextbox shows this output:
First line
Second line
Textbox show this output:
First line Second line
please tell me how to show new line "\n" or return "\r" or similar input as a character output in text or richtextbox. so i can know that newline command is coming from input data.
for example text or richtext box will show this output.
First line \nSecond line
thankx in advance.

Lets say that i have a string which have new line :
string st = "my name is DK" + Environment.NewLine + "Also that means it's my name";
Now that i want to show that there is new line in my text there you go :
textBox1.Text = st.Replace(Environment.NewLine, "%");
This will show the newline chat with % sign

For winforms application set
this.textBox1.Multiline = true;
and use "\r\n" as
textBox1.Text = "First line \r\nSecond line";

You want to either prefix your string with # or you can use a double slash before each n (\n). Both of these are ways of escaping the \ so that it displays instead of being treated as part of a new line.
#"This will show verbatim\n";
"This will show verbatim\\n";
You can utilize this by performing a Replace on your incoming text
richTextBox1.Text = richTextBox1.Text.Replace("\n", "\n\\n");
richTextBox1.Text = richTextBox1.Text.Replace("\r\n", "\r\n\\n");
In the replace, I left the original linebreak so that it will be there, just followed by the displaying version. You can take those out if you dont want that. :)

Use the combination "\r\n" (or Environment.NewLine constant which contains just that).

Change Your text box property from single line to Multiline then it will change to new line
TextBox1.TextMode = TextBoxMode.MultiLine;
TextBox1.Text = "First line \n New line ";

TextBoxt1.Text ="FirstLine \r\n SecondLine";
