User(s) can reproduce this bug

When you have a TextBox control with its type set to MultiLine, .NET inserts an additional encoded line break to the output. IE 9 seems to ignore this linebreak, but other brwosers show it, causing incorrect behavior.

This happens when you assign text to the control, but also on the first load when no text is assigned, causing an extra linebreak to appear in the final HTML.

Details (expand)

Visual Studio 2012 RC

1. Create a new ASPX Web Form site
2. In Default.aspx add the following control:

<asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine"></asp:TextBox>

3. In Code Behind, assign some text in Page_Load:

protected void Page_Load(object sender, EventArgs e)
{
TextBox1.Text = "Test";
}

4. View the page in the browser.

Windows 7

The control is converted into a textarea but has an encoded linebreak, like this:

<textarea name="TextBox1" rows="2" cols="20" id="TextBox1">
Test</textarea>

The control is converted into a textarea without the encoded linebreak, like this:

<textarea name="TextBox1" rows="2" cols="20" id="TextBox1">Test</textarea>
