The expand setting of ranpanelitem doesn't work after upgrade to the latest version

hello telerik team,
    I have a RadPanelBar with some controls nested in it's ContentTempalte , and set the expland=true. it works well with the previous version, but after upgraded to the new version, it doesn't work.
    And I find the same problem in your own sample: http://demos.telerik.com/aspnet-ajax/panelbar/examples/functionality/templates/defaultcs.aspx

<telerik:RadPanelBar runat="server" ID="RadPanelBar1" Width="742px" Height="330px"
        Skin="Forest" ExpandMode="FullExpandedItem" OnClientLoad="onLoad">
        <Items>
            <telerik:RadPanelItem Expanded="true">
            <HeaderTemplate>
            ......

Below is my code:
<telerik:RadPanelBar ID="rpbSelectUser" runat="server"
                ExpandMode="FullExpandedItem" Height="100%" Width="100%">
                <Items>
                    <telerik:RadPanelItem Expanded="True">
                        <ContentTemplate>
                        <div style="padding:8px 0px">
                        ........

Error using SpellChecker in code behind

I'm trying to use the Telerik.Web.UI.SpellChecker object to check some text server side, but keep getting the following error in the process: "No dictionary loaded. Set the DictionaryPath property from the spell checker settings or copy the dictionaries to ~/App_Data/RadSpell/". I have two samples of code, both of which result in the same error being thrown.

Case 1:

SpellChecker spellChecker = new SpellChecker("~/App_Data/RadSpell");

spellChecker.Text = "Some sample text tecct";

SpellCheckErrors errors = spellChecker.Errors;

Case 2:

SpellChecker spellChecker = new SpellChecker("~/App_Data/RadSpell");

spellChecker.Text = "Some sample text tecct";

SpellCheckErrors errors = spellChecker.CheckText();

I've verified that the dictionary files do exist within the ~/App_Data/RadSpell directory, and they even get loaded into the SpellChecker object (I stepped through the debugger and used the immediate window to get values for spellChecker.CustomDictionarySource.DictionaryPath and spellChecker.CustomDictionarySource.Language:

spellChecker.CustomDictionarySource.DictionaryPath

"~/App_Data/RadSpell"

spellChecker.CustomDictionarySource.Language

"en-US"

These values seem to get set only after I have set the Text value of the SpellChecker object; prior to that (and just after creating the object), these values are null.

I'm using version 2010.3.1109.35 of the Telerik.Web.UI library for .Net 3.5.

Thanks for your help.

RadGrid Export PDF Font

Hi,

I'm having another problem exporting a radgrid to PDF, it seems to be very flakey. Working one minute and then not another. I get this error when I try to apply a font-family style to either the CommandItem, GridDataItem or GridFooterItem:

System.NullReferenceException: Object reference not set to an instance of an object.

at Telerik.Web.Apoc.Pdf.PdfFontCreator.CreateBase14Font(String pdfFontID, Base14Font base14)

at Telerik.Web.Apoc.Pdf.PdfFontCreator.MakeFont(String pdfFontID, Font font)

at Telerik.Web.Apoc.Pdf.FontSetup.AddToResources(PdfFontCreator fontCreator, PdfResources resources)

at Telerik.Web.Apoc.Render.Pdf.PdfRenderer.StopRenderer()

at Telerik.Web.Apoc.StreamRenderer.StopRenderer()

at Telerik.Web.Apoc.Fo.FOTreeBuilder.Parse(XmlReader reader)

This is the code I have in the ItemCreated on the RadGrid:

if (e.Item is GridDataItem)

{

//e.Item.Style["color"] = "white"; //Default color for headeritem/dataitem

foreach (TableCell cell in e.Item.Cells)

{

cell.Style["font-family"] = "Arial Unicode MS";

cell.Style["font-size"] = "10px";

}

if (e.Item is GridFooterItem)

{

foreach (TableCell cell in e.Item.Cells)

{

cell.Style["font-family"] = "Arial Unicode MS";

cell.Style["color"] = "#000";

cell.Style["font-size"] = "8px";

}

if (e.Item is GridCommandItem)

{

//.Style["font-weight"] = "bolder";

e.Item.Style["font-size"] = "10px";

e.Item.Style["font-family"] = "Arial Unicode MS"; //Set UNICODE font

//e.Item.Style["color"] = "#990099";

}

The grid exports with the font family set to Arial but the actual font in the pdf export does not change. I've looked at the tips and tricks and can't see anything missing.

Also, this works on the dev server but not on my dev machine (local copy). Am I missing something, does something need to be set installed on the server. Like I mentioned before it does seem flakey.

Thanks

RadGrid Mixed Sorting: text and number

Is it possible to sort a column by first number then text? I have an ID column with the following data:

CE01
FE05
112
24
DE4
98

Is there any way to sort by first integer then character to give:

24
98
112
CE01
DE4
FE05

Obviously character sorting only will result in 112 being the first row, 24, then 98 etc.

Thanks,
Daniel.

trying to show radcombobox in a radcalendar cell gives error: Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request.

I am trying to add a radcombobox to every cell in the calender. but I get this error when I run the project:
If I add a label as shown in one of your example it works fine but doesnt work with a radcombobox.
Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request.
Protected Sub RadCalendar1_DayRender(ByVal sender As Object, ByVal e As Telerik.Web.UI.Calendar.DayRenderEventArgs)

No postback when clearing RadNumericTextBox

Hi,

I'm using the numerictextbox control with autopostback set to true. This results in postsbacks on changes as expected.
However when the value was already 0 and the user then clears that field to an empty string no postback occurs. The other way around, from empty string to 0 does post back.

How can I make sure clearing a 0 value to an empty string still results in a postback?

Thanks,
Frank.
