TextBox Auto Expandable in ASP.NET

Question

I have a TextBox like this;

<asp:TextBox id="TextBox1" TextMode="SingleLine" runat="server" />

Is there any way makingAuto Expandable without Javascript or any other technology?

Can i do that just with ASP.NET ? (Some properties maybe)

OR what is the easiest way?

"Auto Expandable" is auto re-size widht of 'TextBox'. When i write 5 letters 'TextBox.Widht' should be 50 px, for 10 letters should be 100px for example..! — Soner Gönül, Apr 25 '11 at 07:20

You can use ASP.NET AJAX ResizableControl Extender if you plan on using ajax control toolkit.(Which internally uses javascript I think), I'm not aware of any other non-javascript way.

But this isn't automaticly right? Yes it can provide re-size properties but users must changes size of control. Is there any automaticly way? – Soner Gönül Apr 25 '11 at 07:28
Not that I'm aware of. basically, every action in client-side is handled by javascript. That's the only language browsers understand. – Kamyar Apr 25 '11 at 11:16

You can use the dynamic server tag for setting the Width.

Width='<%# (Eval("DataSourceField").ToString().Length * 8)%>'

protected void TextBox1_TextChanged(object sender, EventArgs e)
    {
        int i = TextBox1.Text.Length;
        int rowsize = (i / 10)+2;
        TextBox1.Rows = rowsize;
        TextBox1.Focus();

You only can make it without javascript if you already know the content and you don't want the width to change dynamically while the user types. Something like Width="<%=(SourceString.Length * 10)%>"

If you already know the content whatz the purpose of letting the user type it (unless you are doing some type test) – V4Vendetta Apr 25 '11 at 07:32
That's a limitation for not using javascript ;) – ariel Apr 25 '11 at 07:34
@bortao Do you know the right syntax for that? **Width="<%=(SourceString.Length * 10)%>"** doesn't work. – Soner Gönül Apr 25 '11 at 08:10
Just put TextBox1.Width = SourceString.Length * 10 on your Page_Load – ariel Apr 25 '11 at 08:16
@bortao Is needed namespace ? Not found SourceString ?? – Soner Gönül Apr 25 '11 at 08:31
SourceString would be the text you would display in the textbox. as i said, this only works if you already have the text before loading the page. – ariel Apr 25 '11 at 08:58
