Index out of range with Biff Export

I am using Excel-Format="Biff" for my excel exports.

If there are no records in the grid, I get an index out of range error on clicking the export button. All other formats work fine. They just output an empty file but does not error out. I am unable to figure out why I get an index out of range error on the "biff" format export. Attached is the error details.

I also tried the code with advanced databinding using NeedDatasource event but I see the same behavior.

<telerik:RadGrid ID="rgParticipantBalances" runat="server" DataSourceID="_dataSrcBalances" OnPreRender="rgParticipantBalances_PreRender"

OnItemCommand="rgParticipantBalances_ItemCommand" OnItemDataBound="rgParticipantBalances_ItemDataBound"

OnItemCreated="rgParticipantBalances_ItemCreated" AllowFilteringByColumn="true" >

ShowExportToPdfButton="true" ShowExportToWordButton="true" ShowExportToCsvButton="true" />

<NoRecordsTemplate>

<div style="color: Red; font-size: 12px; font-family: Verdana, Arial, Helvetica, sans-serif; font-weight: bold">

layout differences between local and published version

Hi,

I'm using OrgChart in one project to display some hierarchies. To adapt the look of it to my project design i'm using the code posted below.

Now, locally it works fine on all browsers I test it (chrome, IE 11, Firefox). If I publish it on the server (IIS 8.5 .NET 4.5) the look on IE change badly.(on other browsers looks fine)

Attached , the images with differences.

Remarks:

I force latest compatibility in header: <meta http-equiv="X-UA-Compatible" content="IE=edge"> so it is not a compatibility issue

AppPool is set to "Integrated" .NET CLR 4.0 no other special configurations

I use the latest update of telerik toolkit.

I had a similar problem with RadTreeView, on IE11 the "plus/minus" default images were not displayed. that one i fix it with custom images from css but in this case will be a bit harder.
RadOrg layout is fine using standard "look and feel"

Thank you,

Ionel

Migration from SitemapManager to RadMenu?

I have inherited an application that has used Telerik.Web.Mvc DLL. It was developed circa 2010. I needed to work on the menu sizes and I asked for help from the Telerik guys. They suggested that the application being so old I should migrate to the latest code. Which I did. But I lost all the Telerik.Web.Mvc sitemap part. And now I am lost. I am not sure what comes after SiteMapManager. I cannot find any documentation on it, I do not understand how to migrate.

Can somebody help me with this issue?

Thank you.

OnDayRender not changing background color until month is changed.

I am changing the background color of a date ( that is being provided from the database ) by using the Calendar OnDayRender. The problem is that when the page initially loads the background color is not present. But if I change the month, then go back to the previous month, the background color appears.

ASP:

<telerik:RadDatePicker AutoPostBack="true" OnSelectedDateChanged="rdpEnd_SelectedDateChanged" ID="rdpEnd" ToolTip="" class="form-control" Style="width: 100%;" Height="30px" aria-describedby="ptoEndDate" runat="server">

<DatePopupButton ToolTip="" />

<Calendar runat="server" ShowRowHeaders="false" OnDayRender="CustomizeDay">

</Calendar>

</telerik:RadDatePicker>

C#

protected void CustomizeDay(object sender, Telerik.Web.UI.Calendar.DayRenderEventArgs e)

{

DateTime CurrentDate = e.Day.Date;

using (DataClassesDataContext db = new DataClassesDataContext())

{

if(db.Calendars.Where(x => x.date.Value.Date == e.Day.Date).Any())

{

TableCell currentCell = e.Cell;

currentCell.Style["background-color"] = "#000000";

}

Hide Rows in Grid Edit Form

hello
i have the following problem
i have a radgrid which is totally builded in code behind because it must be bound to different data types
you can see a preview in this page
the user may update a record or insert a new one
when entering in edit mode, some rows in the edit form should be hidden based on the selection of the main item (the INST_MODEL value that cannot be changed in edit mode)
following is the codebehind of the ascx (i omit fo simplicity the part of code that builds customedittemplate)

so, when selecting an item with INST_MODEL = GA_CP-LI-COR LI-7200, for example, the rows with INST_SA[...] labels should be hidden

how can i do it?!

thanks a lot

Full radgrid documentation?

When setting up a RadGrid in XML, you can set a variety of properties such as DataSourceID, AllowPaging, ImagesPath, AllowAutomaticInserts, etc.

I know that these are scattered throughout the tutorials on your website but is there anywhere or is there any document that has a list of all of these properties in the same place with associated descriptions of what they are used for? I am looking for something like your old CMS documentation only for your new stuff. Does that exist?

RadCheckBox

I'm a noob to Telerik controls. I just purchased the UI for ASP.NET AJAX controls. I just started playing with them and I'm stuck getting a simple RadCheckBox deployed. I've got the RadScriptManager and RadSkinManger in my aspx page. I added a RadCheckBox which for some reason shows as a button in the IDE. I've tried configuring many different properties of the check box. When I run it all I see is the Text I have defined for it. There is no checkbox to click. If I click the text it behaves (the first click) like a button (it depresses) but then on subsequent clicks, nothing.

I'm sure there is something super simple that I'm just not seeing. I haven't played with any other controls so I'm not sure if I'm not configured properly?

Thanks for any help!
