Good afternoon All,
I'm implementing a RadNumericTextbox for a timesheet entry page where the users are required to enter their time in half hour increments. 
I've tried attaching a RegularExpressionValidator to the control which has it's ValidationExpression set to "^\d+\.[05]$". 
I would expect an error on anything not ending with a 0 or 5.  I can't get this to accept an entry ending in a 0 (like 1.0 or 3.0).  It accepts entries ending in .5, as expected.

If I set the ValidationExpression to "^\d+\.[12]$", it catches anything that doesn't end with a 1 or 2 - as I would expect.

Is there something about an entry ending in 0?

Here's the aspx for the Textbox

 

 

<telerik:RadNumericTextBox ID="numtxtMonday" runat="server"

 

 

ButtonsPosition="Right"

 

 

EnabledStyle-HorizontalAlign="right"

 

 

IncrementSettings-Step="0.5"

 

 

InvalidStyle-ForeColor="red"

 

 

MaxValue="24" MinValue="0"

 

 

NumberFormat-DecimalSeparator="."

 

 

NumberFormat-DecimalDigits="1" NumberFormat-GroupSeparator=""

 

 

NumberFormat-AllowRounding="true"

 

 

ShowSpinButtons="true" Type="Number" ValidationGroup="saveTime"

 

 

Width="75px" Value="0.0" >

 

 

</telerik:RadNumericTextBox>

thanks!

Hello Sheryl,

RadNumericTextBox stores and passes its value as a number. So if you enter "1.0", the control will report its value as 1 to the validator. That's why the validation fails for entries ending in ".0".

Please modify your validation expression or use a custom validator.
