The process cannot access the file because it is being used by another process.

Hi,

Im uploading a file using RadAsyncUpload control and I wanted to check if the image to be uploaded is really image, not just another file changed of extension name. Code below:

The error is triggered on the .SaveAs() function

String fileExt = rfile_image.UploadedFiles[0].FileName.Substring(rfile_image.UploadedFiles[0].FileName.LastIndexOf('.') + 1).ToUpper();
byte[] tmp = imageHeader[fileExt];
byte[] header = new byte[tmp.Length];
rfile_image.UploadedFiles[0].InputStream.Read(header, 0, header.Length);

if (!CompareArray(tmp, header))
{
//invalid content type
rfile_image.Dispose();
rfile_image.UploadedFiles[0].InputStream.Close();
rfile_image.UploadedFiles[0].InputStream.Dispose();

returnError("Filename Invalid");
}
else
{
//valid content type, continue with saving
fileUrl = "C:\\data\\" + fileWithPath;

rfile_image.UploadedFiles[0].SaveAs(fileUrl,true);
  }

HTML Pie Chart

I have an Pie Chart looking like this one.
Is it possible on mouse hover to show me the real number and in the fixed labels to show me the percentage? Because I try some ways but doesn't work. I tried with the {N} for fixed and {P} for percentage but is not good this solution.

RadTextBox: Set # of characters to wrap at

I have a radtextbox which is used to enter text which is then laid out on a pdf form. The pdf form is multiline, limited to 55 characters per line.

Is there a way I can tell the radtextbox to automatically wrap at 55 characters, so what people see on the screen is more indicative of what will appear in the pdf form?

I've fiddled with hard-coding the width parameter, but this doesn't seem to work well, because people have different font sizes specified via control panel, and the control renders with different default fonts in various browsers. Unfortunately I didn't see a "WrapAt" property I could set to 55 :)

Telerik RadButtons background color problem

Hi telerik admins

our button background colors do not display correctly in some browsers. How can I solve this problem?

Chrome (http://prntscr.com/2bkbm4) = the most accurate and best display

-----------------------------------------------------
On Firefox and Internet Explorer latest version

Normal: http://prntscr.com/2bkcju
Mouse hover: http://prntscr.com/2bkcqb

This code:

<telerik:RadButton CssClass="blur" ID="RadButtonSil" runat="server" Text="sil" OnClientClicking="RadConfirm" OnClick="RadButtonSil_Click" Height="40px" BackColor="#A52645" BorderColor="#A52645" Font-Size="15px" ForeColor="White">

<Icon PrimaryIconUrl="/img/buton-sil.png" PrimaryIconTop="12px" PrimaryIconLeft="12" PrimaryIconHeight="18px" PrimaryIconWidth="18" />

</telerik:RadButton>

-----------------------------------------------------

chrome and opera are working correctly.

Hello,

Is there is a way to communicate with Microsoft Exchange Server by using RadScheduler's ExchangeSchedulerProvider without using web services?

Could you please provide more examples of using ExchangeSchedulerProvider beside what you have on your demo site?

Thank you very much
