TextMode property of TextBox in ASP.NET

1:52 AMFriday, December 26, 2014
In visual studio 2010 you can assign only three values to the TextMode property , Those values are SingleLine , MultiLine and Password. But in visual studio 2012 you can set lots of value to the TextMode property Those values are SingleLine , MultiLine, Password, Email,Date , DateTime,URl etc All values are given below diagram.
Now all values we are using one by one :
MultiLine : In MultiLine TextBox you can take multiple rows but in single line TextBox you can take only single row. MultiLine TextBox is used where you need multiple rows like address of person. 

Lets take an example of MultiLine TextBox . Drag one TextBox control to the design window and set MultiLine to TextMode property.

<%@ Page Language="C#" %>

<!DOCTYPE html>

<script runat="server">

</script>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
 
    </div>
        <asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine" Width="213px"></asp:TextBox>
        <br />
        <asp:Button ID="Button1" runat="server" Text="Button" />
    </form>
</body>
</html>

Output
Multiline TextBox
SingleLine TextBox : In SingleLine TextBox You can take only single row means your TextBox does not support enter key. Lets take an example of SingleLine TextBox.
<%@ Page Language="C#" %>

<!DOCTYPE html>

<script runat="server">

</script>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

    </form>
</body>
</html>
