Multiline TextBox multiple newline

Question

I set a value for a Multiline Textbox like this.

textBox1.Text = "Line1\r\n\r\nLine2"; 

But, only one line space in output.

When I read the value of textbox, I read "Line1\r\nLine2";

Why does ASP.NET not support more then one lineline character?

Answer 1

You need to set the textbox to be multiline, this can be done two ways:

In the control:

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

Code Behind:

MyBox.TextMode = TextBoxMode.MultiLine; MyBox.Rows = 10; 

This will render as a <textarea>

Answer 2

textBox1.Text = "Line1" + Environment.NewLine + "Line2"; 

Also the markup needs to include TextMode="MultiLine" (otherwise it shows text as one line)

<asp:TextBox ID="multitxt" runat="server" TextMode="MultiLine" ></asp:TextBox>
