Numeric keypad dot/comma behavior

I have a query. I have changed DecimalSeparator as (,) and GroupSeparator as (.) in control panel. Now opening the Excel sheet and type (5.5 , (.) changed to (,) i.e. (5.5) ----->(5,5). I need to know how this behavior works in DataGridView? I have tried to find it, but I'm still confused. Please let me know what is the behavior of the datagrid after changing the decimal separator.

C# textbox with mixed Western and Arabic text

I would like to display mixed western & arabic data read from a file into a text box.
An example of the data is I want to display is:
"You have", "يوجد لديك"
I read the data in as follows:
String tsIn = File.ReadAllText(tbxTSFileName.Text, Encoding.UTF8);
tbxBefore.Text = tsIn;
I cannot see any properties that let me set the textbox to "mixed" encoding.
When I open the file in Notepad++ I select Encoding>Character sets>Arabic>ISO 8859-6.
To make matters even more complicated, I would want to use the same textbox for other languages too, so the solution needs to work in all/most cases.

You need to show us the assignment to the textbox - for instance, is this a WinForms textbox, a WPF textbox or an HTML textbox.
Strings in C# are unicode - so can definitely hold Arabic.
You are reading UTF8 format which supports Arabic so I cannot tell what your actual problem is. Your tsIn could easily contain Arabic - is your problem that you cannot see Arabic in your WinForms TextBox ? This link has a lot of detail on displaying arabic on WinForms
Winforms Arabic Input text box

Multilingual characters in GridView

I have a gridView built using asp.net. I have a text box in the grid view which accepts user input.
When the user gives any multilingual character for example "您好" , it is stored as "???"
How can I fix this issue?

In database table change the column datatype to nvarchar. this works for me to store text of different languages.

Allow text from different cultures in Textbox C#

I have an application in which username is both in English and Japanese(for Japanese users.)
I am retrieving username from database and want to allow both English and Japanese cultures' username in my text box that displays username.
How to do it?

There is a property call ImeMode for text box which is by default "No control" which allow you to enter both English and Japanese
There is also other options like Hiragana,katagana,Alpha etc...
And regarding question of comparing string there is no need to worry about it is work with Unicode so it will compare both English and Japanese text.

RDLC exported to excel to show negative numbers in parentheses

I have an rdlc file with cells showing decimals.
How do I convert a negative number to have parenthesis?
I can't display it as a string, because when the report is exported it treats in as a string and throws an error that the number could not convert a string.
I've tried adding #,0:c0 for the format property but this didn't work.
Any suggestions?

Try to not use the Format function in the Expression of your Placeholder, instead in the text box (or cell) properties, you can set the type and the format of it.
In the properties, there is a section called Number in which you specify that the textbox must contains numbers of a specificated category.
Here is an image to explain:
As you can see, there is an option to set how to display negative numbers (the one selected).
Now, I'm sure that this will works if you export the report in PDF but I hope this will be the same for Excel's export

I worked it out, sorry to answer my own question.
if I use the following in the format property #,0;(-#,0) it works fine.

In my case below custom expression solved my problem.
''#,0.00;''(#,0.00);
