Grouping error, datacolumn nor a datarelation groupedtable0

.Net 3.5
Telerik 2010.3.1317.35

I have a datagrid that has defined columns, and autogenerated columns are set to false,
The dataseource is a datatable and all my databindings are set on datatextfields.

on itemdatabound i compare two of the fields ((int)maxRead and (int)maxNote) and depending on the result i set the row font to bold (to show unread posts)

but as soon as i group any of the columns i get,
"maxRead is neither a DataColumn nor a DataRelation for table GroupedTable0."

I tried adding the maxRead as a defined column in the grid but that gave the same result.

heres my code,
i get the error on the "if ((int)drw["maxRead"] != (int)drw["maxNote"

])'" row below.

protected void grCaseList_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item.DataItem is DataRowView)

{

DataRowView drw = (DataRowView)e.Item.DataItem;

if ((int)drw["maxRead"] != (int)drw["maxNote"])

{

e.Item.Font.Bold = true;

}

Bullets are not properly observing defined css styles in design mode

Take the following code and paste it into the editor in HTML mode...

<html>

<head>

<title></title>

<style type="text/css">

OL LI {LIST-STYLE-TYPE: upper-roman;}

OL LI OL LI {LIST-STYLE-TYPE: upper-alpha;}

OL LI OL LI OL LI {LIST-STYLE-TYPE: decimal;}

</style>

</head>

<body>

<ol>

<li>Test...

<ol>

<li>add sub bullet after this item...

</li>

<li>it most likely got formatted with an "A" and not a "1"<br />

<ol>

<li>It should have been a 1 like this line</li>

</ol>

</li>

</ol>

</li>

</ol>

</body>

</html>

Flip back to design view and it looks great. Then in design view add a sub bullet to bullet A. It will be formatted with an "A" instead of a "1" that the css style defines. But, if you switch back to HTML view and then back to Design view the formatting is correct. Am I doing something wrong or is this a known issue?

I could not find in the documentation an explanation for the callbackFnName parameter of RadWindowManager.RadAlert.
It works for me when I have null there, but I am just guessing.

RadNumericTextbox spinbuttons are invisible

I have several RadNumericTextBoxes with Skin="", using the RadFormDecorator to apply the "Telerik" skin. That is working fine. However, when I try to show spin buttons - they are there, but invisible. I can click to the right of the numeric text box and the numbers change up and down, but I can't see the arrows. If I change the Skin to ="Telerik", the spin icons show up but the textbox does not skin, it goes back to standard textbox format. Can anyone help me figure out how to get the spin boxes to show? Thanks.

<telerik:RadFormDecorator ID="RadFormDecorator1" Runat="server"

DecoratedControls="All" Skin="Telerik" />

<table id="FormTable" cellspacing="2" cellpadding="1" width="100%" border="2" rules="none"

style="border-collapse: collapse;" frame="border" bgcolor="#EBEBEB">

<tr class="EditFormHeader">

<td style="font-size: small">

radGrid inside RadPanelBarItem Template

I am trying to setup a datagrid inside a RadPanelItem template.
my setup is as follows (code is abreviated up to the grid)

    
            <telerik:RadPanelBar> 
        
            <Items> 
        
            <telerik:RadPanelItem> 
        
            <Items> 
        
            <telerik:RadPanelItem> 
        
            <ItemTemplate> 
        
            <telerik:RadGrid ID="rgrdNBDetail" runat="server" GridLines="None" AutoGenerateColumns="false" PageSize="10">  
        
            <ClientSettings> 
        
              <Scrolling AllowScroll="false" /> 
        
              <ClientEvents OnRowClick="rGrid_RowClick"/>  
        
            </ClientSettings> 
        
            <MasterTableView ClientDataKeyNames="ID">  
        
            <Columns> 
        
            <telerik:GridBoundColumn DataField="ID" Visible="false"> </telerik:GridBoundColumn> 
        
            <telerik:GridBoundColumn DataField="SPCX" Visible="false">
        
            </telerik:GridBoundColumn> 
        
            <telerik:GridBoundColumn DataField="SPCY" Visible="false">  
        
            </telerik:GridBoundColumn> 
        
            <telerik:GridBoundColumn HeaderText="Name" DataField="SiteName"/>  
        
            <telerik:GridBoundColumn HeaderText="Distance" DataField="Distance"/>  
        
            </Columns> 
        
            </MasterTableView> 
        
            <PagerStyle AlwaysVisible="false" /> 
        
            </telerik:RadGrid> 
        
            </ItemTemplate> 
        
            </telerik:RadPanelItem> 
        
            </Items> 
        
            </telerik:RadPanelItem> 
        
            ...

Notice I am not declaring a datasource as I will be binding this grid through a webservice on the client side. After the webservice is called and I attempt to databind the grid, var tableView = datagrid.get_masterTableView(); it is not returning a tableView (value is null).

    
            ...   
        
            var item = panelbar.findItemByValue('NBDetail');  
        
            var datagrid = item.findControl('rgrdNBDetail');  
        
            var tableView = datagrid.get_masterTableView();  
        
            tableView.set_dataSource(data);  
        
            tableView.dataBind();  
        
            tableView.set_virtualItemCount(data.count);  
        
            ...

What do I need to do to enable clientside databinding on the grid object inside the radPanelItem template? It's appears that the TableView is not being created server side when it is located inside the template so I can not get a reference to it. (I moved the grid outside the panel and it works fine) Is this the correct way to go about accomplishing this task?
