Solution 2

Use AJAX FilteredTextBoxExtender Control[^] like this:

C#

<asp:textbox id="TextBox1" runat="server"></asp:textbox>

<cc1:filteredtextboxextender id="FilteredTextBoxExtender1"  runat="server" validchars="10" targetcontrolid="TextBox1" >
</cc1:filteredtextboxextender>

Solution 1

Use KeyPress event.

Eg.

C#

protected void YourTextBox_KeyPress(object sender, KeyPressEventArgs e)
{
    var allowKeys = new[] { Keys.Back, Keys.D0, Keys.D1 };
    e.Handled = !allowKeys .Contains((Keys)e.KeyChar);
}

I hope It will help you.

Good luck.
