For count characters 

TextBox.Text.Length;

and if you want validate number goes over 50 that add tag in text.

Maybe this in my perception:

int countWord = Textbox.Text.Length();

if(countWord > 50){
    string text = Textbox.Text.ToString()+"SomeTag";
}else{
    string text = Textbox.Text.ToString();
}

This is the property to see how long the text is during a postback:

TextBox.Text.Length;

TextBox: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.textbox.aspx

Text Property: http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.textbox.text.aspx

String Length Property: http://msdn.microsoft.com/en-us/library/system.string.length.aspx

String str = TextBox.Text;

if(str.Length > 50)
{
   str = str.SubString(0, 50) + "<br/>" + str.SubString(50);
}
