How to purge padding space between the image border and QRCode symbol?

Dear All,

I have the following code to generate QR Code dynamically:

public Image GetQRCode(string sUrl, int iDotSize)

{

var code = new RadBarcode();

code.Text = sUrl;

code.Type = BarcodeType.QRCode;

code.OutputType = BarcodeOutputType.EmbeddedPNG;

code.QRCodeSettings.Mode = Telerik.Web.UI.Barcode.Modes.CodeMode.Byte;

code.QRCodeSettings.ErrorCorrectionLevel = Telerik.Web.UI.Barcode.Modes.ErrorCorrectionLevel.L;

code.QRCodeSettings.DotSize = iDotSize;

code.QRCodeSettings.Version = 2;

code.QRCodeSettings.ECI = Telerik.Web.UI.Barcode.Modes.ECIMode.None;

//code.QRCodeSettings.DotSize = 0; // no changes, space is always there

//code.Attributes.Add("Width", "310px"); // no changes, space is always there

//code.Attributes.Add("Height", "310px"); // no changes, space is always there

return code.GetImage();

}

Can any one tell me how to purge padding space between the image border and QRCode symbol?
According to the documentation changing DotSize to zero should resize the QR symbol to fill up the Width and Height.
It doesn't work, the white space is always there. I tried also several other setting without success.
Greatly appreciate for any helps.

Regards,
Christopher

Show maximum period for task

Hello,

is it possible to somehow show the earliest possible start and latest possible end for a task as the background of the task?

I tried to use the task-template but it is not possible at this point to add a background wider than the task it self. Also it would move when the task is moved.

best regards

Item Value from GridDataItem

In the ItemDataBound event we are no longer to retrieve the Item value using the following code and are getting the value of ' '

If TypeOf e.Item Is GridDataItem Then

Dim dataItem As GridDataItem = DirectCast(e.Item, GridDataItem)

Dim EAFID As String = NoNull(dataItem("row_ID").toString)

This seems to be after a recent update of telerik versions as we were getting valid values.

Any help or clues on why this method of access is not working?

RadFileExplorer.Upload Null after PostBack

We just upgraded our web server from Windows Server 2003 R2 with IIS 6.? to Windows Server 2012 R2 with IIS 8.5.9600.

We also upgraded the Telerik controls from 2010.3.1317.35 to 2016.2.607.35.

A very simplified page example is:

<body>

<form id="form1" runat="server">

<asp:HiddenField ID="hfToolId" runat="server" />

<asp:HiddenField ID="hfTempDirectory" runat="server" />

<telerik:RadScriptManager ID="RadScriptManager1" runat="server" EnablePageMethods="true">

</telerik:RadScriptManager>

<asp:Button ID="Button1" runat="server" Text="Button" />

<div>

<telerik:RadFileExplorer ID="rfeDocs" runat="server" OnClientFileOpen="OnClientFileOpen"

DisplayUpFolderItem="false" EnableCreateNewFolder="false" Width="100%">

<Configuration SearchPatterns="*.*" MaxUploadFileSize="104857600" />

</telerik:RadFileExplorer>

</div>

</form>

</body>

Its associated code behind is:

01.Partial Class _Default

02. Inherits System.Web.UI.Page

03.

04. Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load

05. SetupFileExplorer()

06. End Sub

07.

08. Private Sub SetupFileExplorer()

09. Dim controls As Telerik.Web.UI.FileExplorer.FileExplorerControls = 0

10. Dim di As IO.DirectoryInfo

11. Dim newTempDirectory As String = String.Empty

12. Dim path(0) As String

13. Dim s = CType(rfeDocs.FindControl("splitter"), RadSplitter)

14. Dim toolId As Integer

15.

16. If IsNumeric(hfToolId.Value) Then

17. toolId = CInt(hfToolId.Value)

18. ElseIf Request.QueryString("equipmentid") IsNot Nothing Then

19. toolId = CInt(Request.QueryString("equipmentid"))

20. Else

21. toolId = 0

22. End If

23.

24. For Each item As RadToolBarItem In rfeDocs.ToolBar.Items

25. If TypeOf item Is RadToolBarButton Then

26. CType(item, RadToolBarButton).CausesValidation = False

27. End If

28. Next

29.

30. If toolId > 0 Then

31. path(0) = Page.ResolveUrl("~/Tools/" & toolId.ToString())

32. ElseIf Not String.IsNullOrEmpty(hfTempDirectory.Value) Then

33. path(0) = Page.ResolveUrl("~/Tools/" & hfTempDirectory.Value)

34. Else

35. newTempDirectory = Request.LogonUserIdentity.Name().Split(New Char() {"\"c})(1) & Now.Ticks

36. hfTempDirectory.Value = newTempDirectory

37. path(0) = Page.ResolveUrl("~/Tools/" & newTempDirectory)

38. End If

39.

40.

41. di = New IO.DirectoryInfo(Server.MapPath(path(0)))

42.

43. If Not di.Exists Then

44. di.Create()

45. End If

46.

47. rfeDocs.Configuration.ViewPaths = path

48. rfeDocs.Configuration.UploadPaths = path

49. rfeDocs.Configuration.DeletePaths = path

50.

51. rfeDocs.Upload.InitialFileInputsCount = 1

52. rfeDocs.InitialPath = path(0)

53. rfeDocs.Upload.EnableFileInputSkinning = False

54. rfeDocs.Grid.MasterTableView.TableLayout = GridTableLayout.Fixed

55. rfeDocs.Grid.ClientSettings.AllowRowsDragDrop = False

56. rfeDocs.Grid.ClientSettings.Resizing.ResizeGridOnColumnResize = True

57. rfeDocs.VisibleControls = FileExplorer.FileExplorerControls.Toolbar Or FileExplorer.FileExplorerControls.Grid

58.

59. End Sub

60.

61. Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click

62. 'just to force page postback

63. End Sub

64.End Class

The user would normally fill out a form, click a save button (which would cause the postback), then upload files via the RadFileExplorer control. Prior to the server upgrades, the code worked fine, after the upgrades, the page fails on line 51 in the code behind. The rfeDocs.Upload object/property is null/nothing.

Is there anything incorrect with the page for the new version?

Thank you,

James

RadAsyncUpload with iPad - file access

Good day,

I'm trying to use RadAsyncUpload to upload various document types (PDF, doc, docx).

On my iPad, when I click the "Select" button, I only have the option to upload images (see attached).

While searching for an answer, I came across this old blog post indicating it should be possible to upload files from iOS devices: http://www.telerik.com/blogs/uploading-files-with-telerik-s-asp-net-async-upload-control-more-flexible-than-ever

My question is: are images the only filetype that can be uploaded with iOS devices with the RadAsyncUpload control? If not, how can I set it so I can upload PDF/doc/etc?

Thank you!

My code snippet:

<telerik:RadAsyncUpload ID="uploadCV" runat="server"

Skin="MetroTouch"

UseApplicationPoolImpersonation="true"

AutoAddFileInputs="false"

InitialFileInputsCount="1"

AllowedFileExtensions="pdf,doc,docx"

MaxFileInputsCount="1"

ToolTip="Upload your C.V."

OnClientFileUploaded="fileUploaded"

EnableInlineProgress="true"

MultipleFileSelection="Disabled">

</telerik:RadAsyncUpload>

Get custom attributes from appointment item

I've got an aspx page, and in the code behind, I'm building a list of Telerik.Web.UI.Appointment objects, and setting the datasource of the RadScheduler to that list.

For each appointment object I'm adding several attributes to it. Things like CusomerID.

appt.Attributes.Add("CustomerID", 23);

I need to get at this information client side. From the documentation, it appears to me that this should work, but it does not.

var appt = eventArgs.get_appointment();
var list = appt.get_attributes();
var attr = list.getAttribute('CustomerID');

When I run this, attr is always undefined.

So, what is my problem? Am I not adding the attributes in the correct way on the server side, or is something messed up with my client side call?

Passing parameters from page to custom s3 provider

Hi

I have used the custom provider to upload to my amazon s3 bucket. I have set the SubfolderStructure to a path (lets sat abc/def ) but I want to be able to append to this at runtime based on the type of file I am uploading (or a parameter/setting I can set on the control or page), ie keep my images files in my abc/def/images folder and for docs use abc/def/docs so all I need do is store the value "images" or "docs" on the page and pass this to the provider at runtime and append to the SubfolderStructure. I guess a attribute called Path on the RadCloudUpload control would do the job but I couldn't see one?

So my question is, what's the best way of getting a parameter from the page to the provider?

Thanks

Tim
