The virtual and physical paths are not shown in the FileExplorer. I cannot see any folders when running my solution. It is designed to allow clients to select a folder path from their local filesystem. Additionally, it needs to allow users to select a folder path from a initialpath on the server. I was able to create a custom content provider for both task after reviewing and modifying code found in this link, http://www.telerik.com/support/kb/aspnet-ajax/fileexplorer/details/use-radfileexplorer-with-physical-and-shared-folder-s-paths , to no avail.

From stepping through code during debugging, I am getting the paths from the MappingFile.mapping xml file and loading them into the initialPath and viewPath properties.

Copy code

' Get physical and virtual path mappings to initialize the FileExplorer upon page load. This is a helper function

' of the ConfigureFileExplorer function

Public Sub GetPhysicalVirtualPath()

Dim configFile As New XmlDocument()

Dim physicalPathToConfigFile As String = Context.Server.MapPath(Me.pathToConfigFile)

configFile.Load(physicalPathToConfigFile)

' Load the configuration file

Dim rootElement As XmlElement = configFile.DocumentElement

Dim handlerPathSection As XmlNode = rootElement.GetElementsByTagName("genericHandlerPath")(0)

' get all mappings ;

Me._itemHandlerPath = handlerPathSection.InnerText

Me.mappedPathsInConfigFile = New Dictionary(Of String, String)()

Dim mappingsSection As XmlNode = rootElement.GetElementsByTagName("Mappings")(0)

' get all mappings ;

For Each mapping As XmlNode In mappingsSection.ChildNodes

' Get the appropriately categorized path, which is the InternalShare for ReceiveInternal and SendInternal operations

Dim virtualPathAsNode As XmlNode = mapping.SelectSingleNode("VirtualPath")

Dim physicalPathAsNode As XmlNode = mapping.SelectSingleNode("PhysicalPath")

' If neither string is empty, then

If Not String.IsNullOrEmpty(virtualPathAsNode.InnerText) And Not String.IsNullOrEmpty(physicalPathAsNode.InnerText) Then

' Add all mappings to the list

Me.mappedPathsInConfigFile.Add(PathHelper.RemoveEndingSlash(virtualPathAsNode.InnerText, "/"c), PathHelper.RemoveEndingSlash(physicalPathAsNode.InnerText, "\"c))

End If

Next

End Sub

The server or client directory should be shown depending on the requested action (tab's ID) received from a hidden field on the client app. Please see the following:

Copy code

Public Sub GetPhysicalVirtualPath()

Dim configFile As New XmlDocument()

Dim physicalPathToConfigFile As String = Context.Server.MapPath(Me.pathToConfigFile)

configFile.Load(physicalPathToConfigFile)

' Load the configuration file

Dim rootElement As XmlElement = configFile.DocumentElement

Dim handlerPathSection As XmlNode = rootElement.GetElementsByTagName("genericHandlerPath")(0)

' get all mappings ;

Me._itemHandlerPath = handlerPathSection.InnerText

Me.mappedPathsInConfigFile = New Dictionary(Of String, String)()

Dim mappingsSection As XmlNode = rootElement.GetElementsByTagName("Mappings")(0)

' get all mappings ;

For Each mapping As XmlNode In mappingsSection.ChildNodes

' Get the appropriately categorized path, which is the InternalShare for ReceiveInternal and SendInternal operations

Dim virtualPathAsNode As XmlNode = mapping.SelectSingleNode("VirtualPath")

Dim physicalPathAsNode As XmlNode = mapping.SelectSingleNode("PhysicalPath")

' 2/20/14 - If neither string is empty, then

If Not String.IsNullOrEmpty(virtualPathAsNode.InnerText) And Not String.IsNullOrEmpty(physicalPathAsNode.InnerText) Then

' Add all mappings to the list

Me.mappedPathsInConfigFile.Add(PathHelper.RemoveEndingSlash(virtualPathAsNode.InnerText, "/"c), PathHelper.RemoveEndingSlash(physicalPathAsNode.InnerText, "\"c))

End If

Next

End Sub

Can you clarify how the CustomFileSystemProvider.vb file should be used? I used the example provided in the link above. However, I removed the file operations (move, delete, etc.) since I only need to select folders from the directory to build a path to return to the client that will be used for processing needs. Then I added the following extended provider to the end of my page's codepage:

Copy code

Public Class ExtendedFileProviderInternal

Inherits Telerik.Web.UI.Widgets.FileSystemContentProvider

'constructor must be present when overriding a base content provider class

'you can leave it empty

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 Telerik.Web.UI.Widgets.DirectoryItem

'get the directory information

Dim baseDirectory As Telerik.Web.UI.Widgets.DirectoryItem = MyBase.ResolveDirectory(path)

'remove files that we do not want to see

Dim files As New System.Collections.Generic.List(Of Telerik.Web.UI.Widgets.FileItem)()

Dim UnauthextWebConfig As String = System.Configuration.ConfigurationManager.AppSettings("UnAuthorizedFileExtensions")

Dim INVALID_EXTENSIONS As String() = FileExts()

For Each file As Telerik.Web.UI.Widgets.FileItem In baseDirectory.Files

' Get the file extension of the current file, the last element in the sequence

Dim ext As String = file.Name.Split(New Char() {"."c}).Last

' For the Internal version of the file upload control, use this code

' along with the exclusion list in the webconfig to prevent script injection from .sql, .cs, .bat, .exe., .cmd, etc.

If Not INVALID_EXTENSIONS.Contains(ext.ToLower()) Then

files.Add(file)

End If

Next

Dim newDirectory As New Telerik.Web.UI.Widgets.DirectoryItem(baseDirectory.Name, baseDirectory.Location, baseDirectory.FullPath, baseDirectory.Tag, baseDirectory.Permissions, files.ToArray(), _

baseDirectory.Directories)

'return the updated directory information

Return newDirectory

End Function

'  This function gets the custom file extension exclusion list from the web.config/ApplicationSettings set by the app admins

Function FileExts() As String()

Dim extWebConfig As String = System.Configuration.ConfigurationManager.AppSettings("AllowedFileExtensions")

Dim exts As String() = extWebConfig.Split(New Char() {","c})

' If the count of extensions is not zero, then

If (exts.Count = 0) Then

exts(0) = ("undefined")

End If

' Return the array

Return exts

End Function

End Class

I did not make any changes to the PathHelper.vb file. I only kept the New(), GetFileContent(), and CheckWritePermission() functions of the FileSystem.vb file. The CustomFileSystemProvider.vb, FileSystem.vb, MappingFile.mapping, and PathHelper.vb files are kept in my App_Data folder in Visual Studio 2010.

I am running/debugging the web application locally with IIS 7 on Windows 7 OS. The application must access the shared and local directories. Do I need to create virtual directories in IIS for the server filesystem to show in the FileExplorer? Additionally, how can I get the FileExplorer to show the user's local File system? What are your suggestions? Thanks.

RadPanelBar within Formview

I am looking for an example where the the radpanelbar items contain bindable controls from the datasource specified within a formview. I made the following layout but binding would not work.

RadAjaxManager.ajaxRequest from a rad window

In a radwindow I'm trying to run server side code through the RadAjaxManager.ajaxRequest on docuemnt.Ready(). I get he following javascriopt error 0x800a138f - JavaScript runtime error: Unable to get property 'ajaxRequest' of undefined or null reference. I assume the $find("RadAjaxManager1").ajaxRequest("Rebind") line isn't finding the RadAjaxManager Control. Can I not call the ajaxRequest in document.ready()? Is it too early?
The control is named properly from what I can tell.

rgheader class missing from th

Our RadGrid is missing the rgheader class from the th's when it is rendered. Does anyone have any experience with this or any direction on how we can fix/troubleshoot?

I've attached an image of the RadGrid as it appears with no column headers. Note that we purposefully loaded two rows of completely empty data, to confirm that the datasource/ajax request is working correctly (all is well there).

RadGrid declaration:

<telerik:RadGrid ID="AXXRadGrid" runat="server" GridLines="None" AllowAutomaticUpdates="True"

OnItemCommand="AXXRadGrid_ItemCommand" OnItemDataBound="AXXRadGrid_ItemDataBound"

AutoGenerateColumns="false" OnSortCommand="AXXRadGrid_SortCommand" AllowMultiRowSelection="true"

OnItemCreated="AXXRadGrid_ItemCreated" DataSourceID="RequestMasterDataSource"

OnHTMLExporting="AXXRadGrid_HTMLExporting" OnExportCellFormatting="AXXRadGrid_ExcelExportCellFormatting">

<ExportSettings HideStructureColumns="true" />

<MasterTableView TableLayout="Auto" RetrieveDataTypeFromFirstItem="true" CommandItemDisplay="Top">

<CommandItemSettings ShowExportToExcelButton="false" ShowAddNewRecordButton="false"

ShowRefreshButton="false" />

</MasterTableView>

<ClientSettings>

<Selecting AllowRowSelect="True"></Selecting>

<Scrolling AllowScroll="false"></Scrolling>

<Resizing ResizeGridOnColumnResize="True" AllowRowResize="True" AllowColumnResize="True" />

<ClientMessages DragToGroupOrReorder="Drag to group" />

</ClientSettings>

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default">

</telerik:RadGrid>

HTML generated from RadGrid:

Are people still learning WebForms?

This is just a general question, but when people are getting into asp.net, do people still learn webforms? Seems like everyone is always bashing it, saying how much better MVC is.

I think if you use RadScriptManager, RadWindowManger and telerik grids, there's is nothing better for creating a fast LOB web app. You can even put Web API into a webforms website and make client side calls to it. The thing is, I don't want to keep writing Webform sites if no one knows webforms anymore.

I think for writing pages that will also be used in mobile, HTML5/javascript pages and node.js and client/server instead of MVC is the future.

Missing Legend Item in Pie Chart

I have a pie chart where the labels are 0, 1, 2, 3, 4, 5+. But the "0" category doesn't show up in the legend, even though it's showing up in the chart. It works fine if I change the label to "Zero", but won't show up when it's "0". It's also missing from the tool tip. The client template for the tooltip is
"#=category#<br />#=dataItem.code_count# (#=value#%)". Again, the tooltip shows up fine for "Zero", "1", "2", etc., but for "0", #=category# shows up blank. Is there any way to display category labeled "0"?

Grid with custom datasource did not call insert/update/delete methods

Hi,

I have implemented universal list editor, which allow me to simple edit entities by EntityDataSource. It works ok with automatic insert/update/delete functionality.

Now I'm starting new web project based on Code First EF6. So I cannot use EntityDataSource. I downloaded DatabaseDataSource from https://dbcontextdatasource.codeplex.com/

Datasource works correctly for selecting but it does not works with automatic insert/update and delete commands.

I looked to RadGrid source code and it looks that it works only with knowing datasources from .Net framework, but not with custom datasources. The insert/update/delete commands are invoked on Grid but it is not invoked to data source.

Is there some solution how to do with custom datasource or another solution how to works with automatic CUD operations with RadGrid and Code First EF6?

Thanks

Vlad
