I can't seem how to figure out how to get correct decimal values in my footer aggregate using Avg as the aggregate method. Here is the column for the aggregate

    
            <telerik:GridBoundColumn Aggregate="Avg" FooterAggregateFormatString="Avg: {0:0.00}" DataFormatString="{0:0}" HeaderText="Age" HeaderStyle-Wrap="false" UniqueName="age" DataField="age" SortExpression="age" Groupable="false"> 
        
                <ItemStyle Wrap="false" /> 
        
            </telerik:GridBoundColumn>

The values that are being averaged are 24, 10, 7, 14. The average comes out as 13.00 when it should come out as 13.75. If I change the FooterAggregateFormatString="Avg: {0:0.00}" to FooterAggregateFormatString="Avg: {0:0}", it rounds down to 13 instead of up to 14.

Can you tell me how to get an accurate average using this method. Thanks.

telerik radgrid filter of datetime column displays in small size

I am using Radgrid for displaying data & which uses filter columns at the top.
The problem I am having is, some of the column types is "DateTime" & it shows a Calendar control but sometimes the textbox field where DateTime has to be entered or displayed (in case date picked up from Calendar) shows very very small size where users hardly see 1 or 2 digits.

Can somebody throw some light on this? Whats the reason getting the filter box small size for DateTime column? All other filter boxes (with no calendar input) were of normal size at the same time. This happens only for datetime filter on probably specpfic occasions.

Thank you

btn.Enable only if grid validates

I guess I should know this, but... I have a grid where every control does not auto-postback. It allows mult-row edit, has dropdowns, date and time pickers, etc. If one of the fields is invalid, like text in a datepicker, I want to disable the Update button. I believe all of this needs to be done on the client side. And I believe I need to funnel all validation through one JavaScript method that determines if there are any validation issues (btn.enabled=allControlsValid;).

But I want to do this in the most performant manner, which rules out server-side validation. ( ? ) There could be a 100 rows in this grid with 30 columns, and maybe 10 of them are editable. I think the user would perceive a delay if I checked 1000 cells on every cell edit. So I'm guessing the check should only be made when focus moves from one row to another.
Can someone guide me in the right direction?

Thanks!

RadWindowManager with RadWindow that has an UpdatePanel

In the past I've successfully used a single RadWindow on a page. It works fine.

Now I need to have one RadWindow appear on top of another RadWindow. Reading through Telerik's documentation I've learned that I need to introduce the RadWindowManager. I did so but encountered this error: http://www.telerik.com/support/kb/aspnet-ajax/window/cannot-unregister-updatepanel-with-id-updatepanelid-since-it-was-not-registered-with-the-scriptmanager.aspx

There is NO WAY I can get rid of the UpdatePanel in my RadWindow. It must stay.

So reading the 1st suggested workaround I tried doing this:

<telerik:RadWindowManager ID="rwManager" runat="server" /> <telerik:RadWindow ID="rwNewMuckpile" runat="server" Behaviors="Move" EnableShadow="true" VisibleStatusbar="false" VisibleTitlebar="false" AutoSize="true" Modal="true"> <ContentTemplate> <asp:UpdatePanel ID="UpdatePanel2" runat="server"> <ContentTemplate> <div class="dialogHeader"> Move Muck </div> . . . 

But it just produced another error: "Microsoft JScript runtime error: Sys.InvalidOperationException: Two components with the same id 'ctl00_ContentPlaceHolder1_Mucking_rwNewMuckpile' can't be added to the application."

So what should I do?

Spin buttons below NumericTextBox in IE

I am using v2012.1.411.35 and having an issue with the numerictextbox and spin buttons. I have the spin buttons turned on and no other attributes set other than skin.

<telerik:RadNumericTextBox ID="RadNumericTextBox1" ShowSpinButtons="true" runat="server" Skin="Web20"></telerik:RadNumericTextBox>

In IE (7,8,9), the spin buttons appear below the textbox no matter the width set on the control. Is there a css class that could have been overridden somewhere that could be affecting the control?

Any suggestions?
