Error while publishing website in IIS7

Question

How do i add a New Line "\\n" in the text box I had created in asp.net web site. For instance

TextBoxA.Text="Hello";
TextBoxB.Text="World";
TextBoxC="Hello
     World"

Like:

TextBoxC.Text=TextBoxA.Text+"\n"(or something)+TextBoxB.Text;

Answer 1

TextBoxC.Text= string.Format("{0}\n{1}", TextBoxA.Text,TextBoxB.Text);

or

TextBoxC.Text= TextBoxA.Text + "\n" + TextBoxB.Text;

Now, for this to work you have to make the textbox multiline...

<asp:TextBox ID="TextBoxC" runat="server" TextMode="MutiLine" />

Answer 2

You need to use texmode of your textbox.

Add TextMode to multiline.

<asp:TextBox runat="server" ID="MyBox" TextMode="MultiLine" Rows="10" />
