[RESOLVED] StreamReader and TextBox Not Displaying Data Correctly

**weirddemon** · Jul 16th, 2011, 01:47 PM

I need to read a file on a server into a textbox. I did a test on my local PC, to make sure it works the same in a web app as it does on a desktop app.

The data appears to read just fine, but it doesn't display properly. The test file in the screenshot below, shows how the data should be displayed. When using a desktop app, the data displays just like this.

But on the web app, I get this:

Although the TextBox appears to be MultiLine, it only displays the data in the middle of the box and as one line. Am I missing something?

Hello,

Can you show the code that you are using?

I have just tried this:

Code:

        protected void Page_Load(object sender, EventArgs e)
        {
            string fileText = File.ReadAllText(Server.MapPath("TextFile1.txt"));
            this.TextBox1.Text = fileText;
        }

With this:

Code:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine" Rows=20 />
    </div>
    </form>
</body>
</html>

And it worked exactly as expected.

The problem that you could be facing is with the rendering of the Environment.NewLine to br tags in the textbox.

Oops. I never actually set the Multiline property in the source code. I just assumed that since it looked multilined that it would be, like in a desktop app. I know there's still a property in desktop apps, but I couldn't locate it in the properties window and when I Googled it earlier, every post I saw talked about using these elaborate Javascript options to force it.

Thanks

Not a problem at all.

Happy to help!
