[Solved] Re: Can't enter decimal as first character

[-glenn-]

[Yesterday and today I've tried to post the below as a reply to this thread:
http://demos.telerik.com/aspnet-mvc/razor/NumericTextBox
but keep getting a "sorry there's a problem with our server".]

I've run into this problem too. How come I can enter, say, ".34" (no quotes, of course) into the first control (#NumericTextBox) on this page:

http://demos.telerik.com/aspnet-mvc/razor/NumericTextBox

but it doesn't allow the initial "." on my own page?

Is there a new version of the control being used on the demo page?

Thanks!

Hi -Glenn-,

 This is not a known issue. Check this screen cast, which I have made while testing on our online demos.

Hi Georgi. I understand that, as I indicated in my post. What I don't understand is why it's not working for me. I have a field of type C# double with a RangeAttribute specifying it can have a value of 0 to 30. And here's the Razor code for the field:

@(Html.Telerik().NumericTextBoxFor(model => model.VentingVacuum).Spinners(false))

I can enter "0" into the rendered control and the Telerik control reformats it as "0.00" and accepts the field. I can enter "0.2" which is reformatted to "0.22" and is accepted. If I clear out the field then try to type a "." nothing is echoed; I must type "0." in order for the "." to be accepted. In other words, I must enter "0.2" and cannot enter ".2".

Here is the rendered HTML:

<div class="t-widget t-numerictextbox" id="VentingVacuum"><input class="t-input" data-val="true" data-val-number="The field Venting Vacuum must be a number." data-val-range="The field Venting Vacuum must be between 0 and 30." data-val-range-max="30" data-val-range-min="0" data-val-required="The Venting Vacuum field is required." id="VentingVacuum-input" name="VentingVacuum" value="0" /></div>

and the validation JavaScript:

jQuery('#VentingVacuum').tTextBox({val:0, step:1, minValue:0, maxValue:30, digits:2, groupSize:3, negative:1, text:'Enter value', type:'numeric', inputAttributes:{}});

Any ideas?

Hello -Glenn-,

 
I am not sure where could be the issue. Probably there is different regional settings or the keyboard layout is not standard. I will need to replicate the issue locally in order to help you further.

All the best,

Figured it out. In my domain class I had something like this:

public const int MIN_VALUE = 1;
public const int MAX_VALUE = 10;
[Display(Name="Field Name Here")]
[Range(MIN_VALUE, MAX_VALUE)]
public virtual double? Value { get; set; }

The const's should be double not int!

While this was a coding bug perhaps the control could be taught to check the type of the Range values and upcast to double (in this case)? Or maybe issue a warning or error? Just a thought.
