I am new to RadCharts so hopefully there's a simple answer to this. After pro grammatically creating a bar chart and binding it to a datasource as below, if the series has too many items all of my labels are disappearing. Why is this happening and how do I correct it?

Hi,

So I had Radgrid on my page full with data, then I am using Export to Excel method from Radgrid to generate excel file.
Then I save that file TestExcel.xsl on my computer.

The problem is : After that I am trying to open that saved excel file using connection, with that below, then it fires for exception.

_objXConn.ConnectionString = String.Format( _

"Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1""", _fullFilePath)

 

Exception:

 System.Data.OleDb.OleDbException: External table is not in the expected format.

There is no issue with the code when i try to open some other excel files with that connection.
Why is this happening? Can you help me?

Hi,

since there is absolutely no documentation about RadFileExplorer I have to ask the question here.

First of all - NO documentation means really NO.
I'm used from Silverlight that some controls are not describe in the "Controls" section of the help.
But at least there is help (even tho it is just "automatically generated content" in the class references).
But here I find nothing at all.

Anyhow - from the properties I found an event

OnItemCommand

But it seems as if this event is never fired.
My approach is to give the user a browser - after he selects a file I decide if this file should be downloaded, edited with a RadEditor or...

The Idea was - I handle the OnItemCommand.
And I guessed there is a "CommandName==Open" or something like this.
So the idea was:
....OnItemCommand(....) {
if(e.CommandName=="Open")    {
    if(IsFileEditable(e.Path))    {
      string strContent=ReadFile(e.Path);
      RadEditor1.Content=strContent.
      RadFileExplorer1.Visible=false;
      RadEditor1.Visible=true;
      SaveButton.Visible=true;
      CancelButton.Visible=true;
}
.....
BUT - the OnItemCommand handler never get's fired - and due to the missing documentation I have no idea how to solve this.

And YES I have seen the "FileExplorer" sample.
BUT: the things get handled on the client - I need them on the server.
AND: exactly the thing where the FileExplorer comes to play is not visible since this is done in some other APSX file - and this file is not listed in the sample.
So all I could see there was a pages which calls a dialog and from this it get's (with some kind of magic :)) the filepath.

Hi All,
    I have a grid in which a detailed subgrid is binding for each item using DetailTables. Now in the ItemDatabound event, I am not able to detect which item (main grid or sub grid)  is binding. Is there a way to detect this ? Any help would be appreciated.
Thanks in advance

i'm trying to use CssClasses with <telerik:RadMenu but it doesn't seem to work.  Inline formating, i.e. Font-Size does.  What am I missing and where is it documented?

Here's my relevant code:

 

<telerik:RadMenuItem ID="radMenuItem1" runat="server" text="Home" CssClass="radMenuBar" Width

="100px">

 

 

 

 

</telerik:RadMenuItem >

In Telerik CSS

.radMenuBar
{
font-family: Arial, Helvetica, sans-serif ;
font-size: 18px ;
font-weight: bold ; 
text-align: center ;
 }

 

 

 

Thanks for your help,
