Problem with RadNumericTextbox since update

[ManniAT]

Hi,

I have a rad grid bound to a linq datasource.
The grind contains a template row with a RadNumericTextBox.

It runs well in the local webdev server but on IIS 6 it fires an error.
Prior the update to Q1 09 it made no problems.

Details:
If I define the thing like this

<telerik:RadNumericTextBox runat="server" ID="neNumValues" MinValue="1" MaxValue="30" DbValue='<%# Bind("NumItems") %>' NumberFormat-DecimalDigits="0" Width="60px" ShowSpinButtons="True" ShowButton="False" DataType="System.Int32">
                        </telerik:RadNumericTextBox>

I get the following error

Ausnahmeinformation:
    Ausnahmetyp: System.Web.HttpParseException
    Ausnahmemeldung: Objekt des Typs System.Type kann nicht von seiner Zeichenfolgendarstellung System.Int32 für die DataType-Eigenschaft erstellt werden.

Information zu interner Ausnahme (Ebene 1):
    Ausnahmetyp: System.Web.HttpParseException
    Ausnahmemeldung: Objekt des Typs System.Type kann nicht von seiner Zeichenfolgendarstellung System.Int32 für die DataType-Eigenschaft erstellt werden.

Information zu interner Ausnahme (Ebene 2):
    Ausnahmetyp: System.Web.HttpException
    Ausnahmemeldung: Objekt des Typs System.Type kann nicht von seiner Zeichenfolgendarstellung System.Int32 für die DataType-Eigenschaft erstellt werden.

This means in english something like it can't convert the string System.Int32 to a System.Type

If I remove the RadNumericTextBox everything works fine.
Even a GridNumeric works.
But this is not usefull for me, since (as you see) I need to ensure that the value is an integer between 1 and 30.
Currently I help me with a validator - but I would preffere to further use the RadNumericTextBox.

The strange thing for me is, that it runs at the integrated webserver and makes the problem only at the server (W2k3 IIS6)!

I experienced this exact same problem except it was with System.Decimal instead.  It worked fine on my local IIS, but failed when I built it to the server.  I tried many different variations of the value and could not get it to resolve correctly so I ended up temporarily setting the value in the code behind on init.  The page I was using worked fine before updating to the newly released version of the controls.

Hi Adam,

thanks for this implicit tip :)
I replaced my NumTextbox with a bound column.
But to change the datatype in code behind is the real solution - I didn't think of it, although I already have a handler there.
So adding one line of code solved the problem

Thanks again

I opened a support ticket on this issue and they helped me figured out that the Telerik.Web.Design.dll file wasn't in the web app's bin directory.

Thanks for the Info Adam,

would have been great if telerik had posted this fact in an answer to this code.

The question now is - what else depends on the design.dll.
Or if this was just a mistake with NumericTextBox.

Hello Manfred,

The issue is specific to the numeric textbox. We will research to see if it can be avoided.

Hello,

Adam, thanks for your tip. I had similar problem with System.Nullable<Int32> datatype in RadNumericTextbox. Adding reference Telerik.Web.Design.dll solved my problem.

I'm using a 2009 Q3 - internal 1201 version and this error still occurs.
Is there any other workaround???

Best regards,

Hello Henrique,

Have you tried adding the Telerik.Web.Design.dll to the project? If not, please provide more information about your scenario as I cannot reproduce the error with the latest version.

Best wishes,

Hello Pavel,

I tried but it didn't work.

The workaround was to set the DataType in CodeBehind.

BTW, I downloaded the 2009 Q3 SP1 and the problem has gone.
