I'm using a RadGrid with a GridNumericColumn as: 

<telerik:GridNumericColumn DataField="VALUE" HeaderText="Testing Decimal Value" DecimalDigits="6" DataType="System.Decimal" UniqueName="VALUE" NumericType="Number" />

When I enter a decimal value as 1.000015 it is accepted and I'm able to successfully process this value when accessing the hash table in my custom update command. However, when I try to enter a value with as 0.000015 or -0.000015 it turns into scientific notation (0.5E-05) when attempting to update the value and errors out. I have tried setting the AllowRounding to true or false as well as setting the KeepNotRoundedValue to true or false without any change. This problem only occurs if I use a value starting with a 0 and using more than 3 zeros in the precision, i.e. 0.00001. 

I see in the Q1 2012 BETA there is a fix that may resolve my issue? (Fixed: RadNumericTextBox applies scientific notation on focus and wrong value on blur when DecimalDigits and AllowRounding are set and value like 0.0000001 is entered)

I'm unable to update to the BETA at this time and need to know if there is a possible workaround for this precision problem? Any help would be appreciated.

Thanks,
Brandon

Hello Brandon,

I cannot replicate the issue at my end. Try setting the DataFormatString property which worked as expected.
aspx:
<telerik:GridNumericColumn DataField="Discount" HeaderText="Discount ID" KeepNotRoundedValue="true" DataFormatString="{0:f5}"  AllowRounding="false" UniqueName="Num" />

Hi Shinu,

I tried your properties like so without any luck? I also tried setting the DataType to System.Double but not change when using a value of 0 with 6 decimal digits and the first four digits are zero's, i.e. 0.000013 or -0.000013. Works if I only use 3 zeros, 0.000123 or -0.000123. The value turns to 0.3E-05 after update/insert is fired and displays that scientific notation in the grid but once I click in that textbox the value turns back to 0.000013.

<telerik:GridNumericColumn DataField="CAPITAL_ADJ_BASE_RATE_DIST" HeaderText="Capital Adjustment Base Rate Distribution" DataType="System.Decimal" UniqueName="CAPITAL_ADJ_BASE_RATE_DIST" NumericType="Number" KeepNotRoundedValue="true" DataFormatString="{0:f5}" AllowRounding="false" />

Hello Brandon,

The described issue is a bug which is already resolved.
You can find the fix in the latest internal build or in the Q1 2012 Beta release.

I hope this helps.

Hi Mira, I'm instructed not to use BETA versions for my work and need to find a workaround for this problem until the next quarter release is out. Is there any workaround besides doing away with the numeric column editor altogether?

We've been experiencing a similar problem.  When editing a value of 0.000001 in a grid column it changes the display to scientific notation like 1E+06.  I installed the Q2 2012 update and the problem is still occuring.  Any ideas what we can do to fix this ?

Hello,

I tried to replicate the unwanted behavior with Q2 2012 version of RadControls, but no avail. Could you please isolate the problem in a small working project and I will debug it locally and come back to you with the findings?

Support ticket 563762 submitted for this issue.  Attached a .zip file of the code and screen shots of the what the grid is doing in displaying .000001 in scientific notation.
