Index was outside the bounds of the array

[Roar]

Hi,

I'm trying to use the RadMaskedNumericInput as follows;

<telerik:RadMaskedNumericInput
                Grid.Row="6"
                Grid.Column="1"
                Value="{Binding Mileage}"
                EmptyContent="kilometer"
                FormatString="D"
                Mask="d"
                IsClearButtonVisible="False"
                VerticalAlignment="Center"
                VerticalContentAlignment="Center"
                />

...where the bound 'Mileage'-property is an Int. But when I try to input a number at runtime, I get the following exception;

"Index was outside the bounds of the array."

And the stacktrace;

Hi Roar,

What version are you using to test this. I tested this with the latest ones and I cannot seem to reproduce this exception. Thank you.

Oh man. I find this VERY frustrating. I added a couple lines of xaml...I get this exact same error! WTF! Then...after trying a few things out, googling a few things......hhhmmm....close and reload the solution. POOF! Goes away.

 

Come on guys! WTF? Really? Stuff like this, inconsistencies LIKE THIS are what make me distrust your product. You need to do better.

 

PS Telling someone "oh, I don't get that error" is NOT helpful! Actually, it only serves to make me angrier. Think "the Hulk" angry actually and you're in the right ball park of frustration you cause by that comment.

Hi

same issue on lastest version when setting Mask='d' or 'n'; even the demo has it.
I need support for integers or floating points input; I think the way is setting mask to 'D' for integers and 'N' for floating point numbers.

Sincerely
Ivano

Hi Ivano,

 I am still not able to reproduce this. However, what you can try is using the '#' token, which is a non-required numeric token.

All the best,

Hi,
open your demo (more masket input examples); choose Numeric Input) and put "D" or "N" in the mask field; the issue is related to capital letters. Setting "n" or "d" you don't get any error but input is limited to one digit (?)
Anyway which mask setting for integers and floating point number?

Sincerely
Ivano

Hello Ivano,

You can find a list of mask tokens here. I hope it will help, still let us know if you need more info.
