Its still unclear, could explain it with a sample example?

Please restructure your sentence, it's a bit confusing ("...and values is not more then 10 digit no..."?!?).
Do you want max length of string to be 10 or to allow input of 10 digits at most?

Have a look at this:
TextBox which accepts only numbers[^]

Creating a Numeric TextBox Control[^]

Good luck!

Solution 3

if you simply wants to restrict number of characters Or digit not more than 10

you can try this

<asp:TextBox ID="TextBox1" MaxLength="10" runat="server"></asp:TextBox>

IMPORTANT!!!
I didn't realize ASP.Net tag! I'm sorry!:(

Limiting maximum length of string is simple, go to Properties Window and look for MaxLength property
or

myTextBox.MaxLength = 10;

At most of times I check my input on KeyPress event.

myTextBox.KeyPress += delegate(object sender, KeyPressEventArgs e)
{
    if (!IsMyCharOk(e.KeyChar))
    {
        //unwanted values are handled B)
        e.Handled = true;
    }
};
