Solution 1

C#

richTextBox1.Text = sFromDate.ToString(/* add your formatting parameters here*/);

Note that each of your operations will overwrite the previous one. You should create the full text using a StringBuilder or similar before setting the text of the textbox.

another question :
How can I display the content in text box in an order?
At present I can display the info in richtextbox but, its not in an order without spaces.
as eg:
XXX05058BATERfgfg9/4/2015 12:00:00 AM9/4/2015 12:00:00 AM.

What I like to see is as below with spaces in textbox.
XXX05058 BATER fgfg 9/4/2015 12:00:00 AM 9/4/2015 12:00:00 AM.

Just add spaces and newline characters, wherever you need them.

First way (recommended):

C#

StringBuilder sb = new StringBuilder();
sb.Append(sEmployeeID + " ");
//...
richTextBox1.Text = sb.ToString();

StringBuilder.Append Method[^]

Second way:

C#

richTextBox1.Text = sEmployeeID;
richTextBox1.Text += " " + sName;
richTextBox1.Text += " " + sSignum;
richTextBox1.Text += " " + sComment;
richTextBox1.Text += " " + sFromDate;
richTextBox1.Text += " " + sToDate;
