Hi Telerik,

I've a trouble..

I set Maximum to 999999 and IsInteger = true which means value can't be more than 999,999 or 6 digits. But when I key in 999999 in my control it round-up and show 1,000,000 ( another i.e. key in 999994 , it round down to 999990 )
How to turn off automatic round function ?

this is my XAML

<telerik:GridViewDataColumn ValidatesOnDataErrors="None" Width="250" DataMemberBinding="{Binding MinAmt}" Header="Minimum Amount"
                        HeaderTextAlignment="Center" TextAlignment="Right"><telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<TextBlock Text="{Binding MinAmt, StringFormat='0,0'}" TextAlignment="Right"                     x:Name="MinAmtTextBlock" Loaded="MinAmtTextBlock_Loaded" />

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

<telerik:GridViewDataColumn.CellEditTemplate>

<DataTemplate>

                  <telerik:RadNumericUpDown Maximum="999999" UpdateValueEvent="PropertyChanged"
                                            ShowButtons="False" PreviewKeyDown="MinAmt_PreviewKeyDown"

        Value="{Binding Amount, Mode=TwoWay, UpdateSourceTrigger=Explicit}"
                                           x:Name="MinAmt" Loaded="MinAmt_Loaded" />

</DataTemplate>

</telerik:GridViewDataColumn.CellEditTemplate>

</telerik:GridViewDataColumn>

please give me some advice
Regard,

Hi Konstantina,

I can't send you a project because it's a company asset. Btw, Can you suggest me how to deal with following business logic in simplest way

- input field is always in RadGridView
- can set control maximum input length (like TextBox:MaxLength) from code behind.
- input data accepts only Numeric (digit)
- can validate input value after user fill in that control
- can use String Format for add comma ig. if user fill 87654321 after RowEditEnded in ViewMode must shows 87,654,321

looking for your response
Thank you,
SweNz

I have a similar problem, and you can reproduce it with your own Q2 2011 samples.
In the NumericUpDown examples, go to the Theming demo, then use the top numeric control, with label NUMERIC FORMAT.
We're trying to use the control to enter credit card numbers. If you try something like 6666666666666012, the control will display
6,666,666,666,666,010, where the last digit is always rounded. If I had entered .....6015, I would have ended up with ......6020.
What's happening here ? The control is bound to a UInt64. Does the control badly support 64-bit numerals ?

Thanks,
Sebastien

It's not ALWAYS a credit card. We have to support multiple card formats, but it has to be a Numeric control.
Please tell me how to disable the rounding on the Numeric control.
