AsyncUpload custom handler - image size problem

I have implemented the custom upload handler and per the demo and it all works fine except, for uploading any images larger than 2 mb.

The file gets uploaded but,the images are corrupted.
Also, I tried creating a thumbprint of the file as it is being uploaded but I get and error when trying to creating and image from the stream.

Image.FromStream(stream);

throws error "invalid parameter".

I would guess there is some settings in web.config which have missed but I can't work it out.

Thanks

Hello,

My Radscheduler header looks like the attached image. I want to bring the previous day and next day arrow keys on the either side of the month name. Like this

<| December 2013 |>. How can I do that? I am attaching an image for that as well. it is named as monthwanted.png

Also there is space between appointments. How can I get rid of that space and make the appointments to be adjacent to each other. I am attaching an image that shows space between the appointments

What am I missing re: PageSizes?

I try to create a RadDataPager as such:

<telerik:RadDataPager runat="server" ID="ProductsListDataPager" PagedControlID="ProductsListView">
<Fields>
<telerik:RadDataPagerButtonField FieldType="FirstPrev" />
<telerik:RadDataPagerButtonField FieldType="Numeric" />
<telerik:RadDataPagerPageSizeField PageSizes="9,18,27,45" />
<telerik:RadDataPagerButtonField FieldType="NextLast" />
</Fields>
</telerik:RadDataPager>

But the PageSizeField line causes my page to crash, saying that I can't assign object[] to Int32[].

What am I doing wrong?

Issues with components over Sonicwall VPN

I have used the Telerik controls at our college for a number of years with great success. However, there has always been an issue with using some of the controls over our Sonicwall VPN which is now causing a problem.

I downloaded the latest trial version yesterday to see if this issue had been rectified but it hadn't.

There are a couple of controls which seem to be affected:

RadComboBox
This does not seem to work at all over the Sonicwall VPN. The control is displayed but on clicking on the item nothing happens. The Javascript error Object doesn't support this property or method is given (Telerik.Web.UI.WebResource.axd) Code:0 Line: 8950 Char: 1. I just dropped a ComboBox onto a page and hard coded some options in to keep everything as simple as possible.

RadGrid
The grid displayed as expected. However, when paging appeared or was selected to be used the same error appeared.

Has anybody else had similar issues, and how can I get round the problem?

Programatically filtering files that can be seen

i was looking at the FileExplorer and wondered if it was possible to Filter Files that can be seen.
I found the following code, which i found at http://www.telerik.com/support/kb/aspnet-ajax/fileexplorer/hide-files-and-folders.aspx :
:

Public Class CustomProvider

Inherits FileSystemContentProvider

Public Sub New(ByVal context As HttpContext, ByVal searchPatterns As String(), ByVal viewPaths As String(), ByVal uploadPaths As String(), ByVal deletePaths As String(), ByVal selectedUrl As String, _

ByVal selectedItemTag As String)

MyBase.New(context, searchPatterns, viewPaths, uploadPaths, deletePaths, selectedUrl, _

selectedItemTag)

End Sub

Public Overloads Overrides Function ResolveDirectory(ByVal path As String) As DirectoryItem

Dim originalFolder As DirectoryItem = MyBase.ResolveDirectory(path)

Dim originalFiles As FileItem() = originalFolder.Files

Dim filteredFiles As New List(Of FileItem)()

' Filter the files

For Each originalFile As FileItem In originalFiles

If Not Me.IsFiltered(originalFile.Name) Then

filteredFiles.Add(originalFile)

End If

Next

Dim newFolder As New

DirectoryItem(originalFolder.Name, originalFolder.Location, originalFolder.FullPath, originalFolder.Tag, originalFolder.Permissions, filteredFiles.ToArray(), _

originalFolder.Directories)

Return newFolder

End Function

Public Overloads Overrides Function ResolveRootDirectoryAsTree(ByVal path As String) As DirectoryItem

Dim originalFolder As DirectoryItem = MyBase.ResolveRootDirectoryAsTree(path)

Dim originalDirectories As DirectoryItem() = originalFolder.Directories

Dim filteredDirectories As New List(Of DirectoryItem)()

' Filter the folders

For Each originalDir As DirectoryItem In originalDirectories

If Not Me.IsFiltered(originalDir.Name) Then

filteredDirectories.Add(originalDir)

End If

Next

Dim newFolder As New

DirectoryItem(originalFolder.Name, originalFolder.Location, originalFolder.FullPath, originalFolder.Tag, originalFolder.Permissions, originalFolder.Files, _

filteredDirectories.ToArray())

Return newFolder

End Function

Private Function IsFiltered(ByVal name As String) As Boolean

If Not name.ToLower().EndsWith(".sys".ToLower.ToString() + ".csv") Then

Return True

End If

' else

Return False

End Function

End Class

i can see how it works, and was wondering if its possible to not have to hardcode what the file 'EndsWith' in the IsFiltered Function.
My files will all be stored in the one Folder (no other Folders will be accessible to the user), and the Files in the Folder should be Filtered depending on who is viewing it.

so, for example, if you are logged in as 'London', you should only see Files that End With '_London.csv'.
equally, if you are logged in as 'Manchester', you should only see Files that End With '_Manchester.csv'.

There are many different Logins, so i would prefer not to have to have a different Folder for each Login.

jquery.min.map 404 errors showing in chrome console

I have noticed some Jquery.min.map 404 errors in the chrome console. When I try to go to one of the lines that has the problem, it refers to a ScriptReserouce that contains a "Telerik.Web"UI" reference.

Is there something that should be turned on or off to prevent these errors. I am using Q1 2013.

[Solved] RadGrid1_ItemCreated prevent RadGrid to expand row details

Hello,

I developed my project in Visual Studio 2013 and my project have a RadGrid with DetailTables inside to able to expand row details. Then I follow demo sample

http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=window

to add a RadWindow for Edit and Add New Record.

All working fine until I added a RadGrid1_ItemCreated code behind to create dynamic URL for Edit link button

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

HyperLink editLink = (HyperLink)e.Item.FindControl("EditLink");

editLink.Attributes["href"] = "javascript:void(0);";

editLink.Attributes["onclick"] = String.Format("return ShowEditForm('{0}','{1}','{2}','{3}');",

e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["EmpID"],

e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["RowID"],

e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["VoucherID"],

e.Item.ItemIndex);

}

I could not expand row details anymore. I get an error in Chrome browser console:

Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object. Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=rsm_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSys…:6

As soon as I took OnItemCreated="RadGrid1_ItemCreated", the expand row works again

Can anyone please look at it? I don't know if this issue cause by Visual Studio 2013

Thanks,
Sam
