Rating values are changed after postback in RadGrid

[Barbaros Saglamtimur]

Hi,

Both GridRatingColumn or RadRating control in a GridTemplateColumn values are changed after postback. I have attached screen shots for before-after postback. As you will see, values are not changed but ratings are. Here is my code:

<telerik:GridTemplateColumn>
    <ItemTemplate>
        <%# Convert.ToDouble(Eval("Yuzde")) %>
    </ItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridRatingColumn DataField="Yuzde">
</telerik:GridRatingColumn>

I have put a button to trigger postback event outside of the grid. RadGrid uses NeedDataSource event to populate data. If I call RadGrid1.Rebind() method in Button1_Click event, everything works fine. What am I missing? Or is this a bug?

Thanks in advance.

Hi barbaros saglamtimur,
I tried to reproduce the problem you describe, but to no avail. I have attached my test page for your reference. Could you please open a new support ticket and send me a simple running project that demonstrates this problem?

Thanks for your replay.
Your solution have same problem, and I found why. Its because culture settings, decimal separator. My server is configured to use Turkish regional settings and Turkish decimal separator is comma. If you pass decimal values with comma RadRating fails. You can reproduce the problem if you change your culture settings to use Turkish (tr-TR). I can see it working without a problem when I change culture setting to en-US. One more note, changing culture at page level or application level works, other decimal formatting methods (like using IFromatProvider, or using new CultureInfo) doesnt work either.

But interesting point is, it does not fail at first load with Turkish format, but after a postback.

Changing culture at page or application level is not acceptable, so I still need a solution.

Thanks
