Question

I have a dynamically created TextBox in a C#/ASP.NET web page that I want to adapt to mobile browsers:

TextBox qtybox = new TextBox();  
qtybox.ID="qtybox";   
qtybox.Text = "0";  
qtybox.Width = 30;   
container.Controls.Add(qtybox);

I see that I can directly set this in a plain HTML <form>:

<input type="number">

…which will then bring up the numeric keyboard.

How can I do this with my dynamic TextBox in the codebehind, or can I?

Is there an alternate way to put a numeric input control on my page dynamically from the codebehind that would work better? Do I need to use JavaScript to “hack” the control after it renders? (I’d rather have a .NET way of doing it if possible.)

Answer 1

I’m writing this from memory, but I think it’s:

qtybox.Attributes.Add("type", "number");
