Hi All,

I have a browser issue with RadNumericTextBox whenever i use MaxLength property. Below is the scenario

My Code

<telerik:RadNumericTextBox ID="xyz" runat="server" MaxLength="9">

<NumberFormat DecimalDigits="3" GroupSeparator="" />

</telerik:RadNumericTextBox>

In IE Browser :

If i enter maxlength value (ex: 123456789), once it loses the focus, then the value has been updated to (ex: 123456789.000) and taking the count of the value as
(entered 9 chars + 4 added chars(.000) = 12).
now the problem is, its exceeding the MaxLength value and showing an error i.e. "you must enter text with 9 or fewer chars" on MouseOver and finally i couldn't save.

In Chrome & Firefox Browsers :

If i enter maxlength value (ex: 123456789), once it loses the focus, then the value has been updated to (ex: 123456789.000) and taking the count of the value as
(entered 9 chars = 9). here its working fine and i can save also.

(rrbGroupTitle) Ribbon Group Title cropped

Hi ,

I noticed that in 2014.2.618.45 version the rrbButtonGroup's width is set to auto and rrbGroupTitle has a inline style, in some cases where the Ribbon Group Title text is longer than the Ribbon Button Group's width, the title text is altered (attached screenshot).

But in your previous version, both the classes had same inline width and hence the Ribbon Group Title was not cropped.

Please suggest!!

Thanks

FileExplorer CSS

I have a rather complex set of CSS that is causing issues with the FileExplorer control. Is there documentation anywhere that describes how to format the control through CSS? I can find documentation about skins but not CSS.

I attached what the control looks like when my CSS is added.

HTML Static Months - SQLDataSource

I've got a SQLDatasource that pulls back a qty on a monthly basis. Currently the XAXIS is the Month. However, If I hard code the month, the data does not correctly line up. If I don't hard code the Items the data is correct; however the month's are not in order.

I've posted two images. The first one is how the data looks through SQL. There are only 4 months, I plan on making a query parameter based on a RadComboBox later. The second is an image of the two Chart's below, I've been toying with. I only need one of them to work properly, just included both to show what I've tried thus far.

I really need help displaying all 12 months in order on the left hand side of the chart, and linking the correct value to be displayed..

RadInputManager - Integration with RadGrid Problem

I have a "RadGrid" for Editing Data.

I have filtering enabled.

I perform validations using the "RadInputManager".

When I try to update the data happens to me what I show in the picture attached.

How I can solve this?

I add the code "aspx" to show the example:

<telerik:RadAjaxManager runat="server">

            </UpdatedControls>

Specified argument was out of the range of valid values. Parameter name: ItemHierarchicalIndex

Got problem with the delete comand in grid.
Scenario: after page loading push the standard button "Delete" at the GridButtonColumnType(buttonColumn.CommandName = "Delete") of any grid item.
Error description:

Specified argument was out of the range of valid values.
Parameter name: ItemHierarchicalIndex

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: ItemHierarchicalIndex

Source Error:

An unhandled exception was generated during the execution of the
            current web request. Information regarding the origin and location of the
            exception can be identified using the exception stack trace below.

Stack Trace:

[ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: ItemHierarchicalIndex]
   Telerik.Web.UI.GridItemCollection.get_Item(String hierarchicalIndex) +103
   Telerik.Web.UI.GridDataItemCollection.get_Item(String hierarchicalIndex) +37

   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +175
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565

The strange is:
If I comment the defined in OnInit() handler lines

    
                        dataGrid.ClientSettings.ClientEvents.OnGridCreated = "GridCreated"; 
        
                        dataGrid.ClientSettings.ClientEvents.OnRowClick = "RowClick"; 
        
                        dataGrid.ClientSettings.ClientEvents.OnCommand = "GridCommand";

No error returned. Everything is fine...
But the current definition of client handlers is:

    
                                function RowClick(sender, eventArgs) {  
        
                                }  
        
                                function GridCommand(sender, args) {  
        
                                }  
        
                                function GridCreated(sender, eventArgs) {  
        
                                }

Please, suggest me to the way of solving the problem.

Problem to export to Excel

Hi

Some of my users need to export to excel a huge quantity of information, 40.000 records or more.

i have two problems

1) The operation takes a lot of time (6 minutes or even more). How can i develop a timeout?

2) In my production server an exception is being triggered. But i cannot reproduce that exception in my development environment, so i don't know where to catch it. Below is a copy of the error i'm getting in the production server.:
