    This works:

            <asp:TextBox ID="TextBox1" runat="server"  
            TextMode="Number" Width="187px"
            onkeypress="return this.value.length<=10" >
        </asp:TextBox>

    If you need to hide the up/down (spinner), then use this:

    <style>

  .myspinhide 
  /* Chrome, Safari, Edge, Opera */
  input::-webkit-outer-spin-button,
  input::-webkit-inner-spin-button 
  {-webkit-appearance: none; margin: 0;}

   /* Firefox */
   .myspinhide input[type=number] {-moz-appearance: textfield;} 
</style>

        <asp:TextBox ID="TextBox1" runat="server"  CssClass="myspinhide"
            TextMode="Number" Width="236px"
            onkeypress="return this.value.length<=10"  >
        </asp:TextBox>
