File Explorer Dynamic path Issue in IIS

Hi Everybody,

I have downloaded the latest version(2011.2.915.35) trial of telerik.

I have an file explorer control in my page in which i need to show folders in user basis,
some folders are common to all users and some are specific to users.

for example :

Users : USER-A, USER-B,

Common folders : ComFolder1,ComFolder2,ComFolder3.

User Specific folders:
FolderUser1--> for USER-A alone
FolderUser2--> for USER-B alone

But all the folders (ComFolder1,ComFolder2,ComFolder3,FolderUser1,FolderUser2) resides in a common root folder called Fileexploredocs/documents.

My requirement is

When USER-A logs in i should show(ComFolder1,ComFolder2,ComFolder3,FolderUser1)
When USER-B logs in i should show(ComFolder1,ComFolder2,ComFolder3,FolderUser2)

For this i used the following class and function:

public partial class _Default : System.Web.UI.Page { protected void

Page_Load(object sender, EventArgs

e) { RadFileExplorer1.Configuration.ContentProviderTypeName =

typeof(CustomProvider).AssemblyQualifiedName; } public class

CustomProvider : FileSystemContentProvider { public

CustomProvider(HttpContext context, string[] searchPatterns, string[] viewPaths,

string[] uploadPaths, string[] deletePaths, string selectedUrl, string

selectedItemTag) : base(context, searchPatterns, viewPaths, uploadPaths,

deletePaths, selectedUrl, selectedItemTag) { } public override

DirectoryItem ResolveDirectory(string path) { DirectoryItem originalFolder

= base.ResolveDirectory(path); FileItem[] originalFiles =

originalFolder.Files; List<FileItem> filteredFiles = new

List<FileItem>(); // Filter the files foreach (FileItem

originalFile in originalFiles) { if

(!this.IsFiltered(originalFile.Name)) { filteredFiles.Add(originalFile); } } DirectoryItem

newFolder = new DirectoryItem(originalFolder.Name, originalFolder.Location,

originalFolder.FullPath, originalFolder.Tag, originalFolder.Permissions,

filteredFiles.ToArray(), originalFolder.Directories); return

newFolder; } public override DirectoryItem

ResolveRootDirectoryAsTree(string path) { DirectoryItem originalFolder =

base.ResolveRootDirectoryAsTree(path); DirectoryItem[] originalDirectories =

originalFolder.Directories; List<DirectoryItem> filteredDirectories =

new List<DirectoryItem>(); // Filter the folders foreach

(DirectoryItem originalDir in originalDirectories) { if

(!this.IsFiltered(originalDir.Name)) { filteredDirectories.Add(originalDir); } } DirectoryItem

newFolder = new DirectoryItem(originalFolder.Name, originalFolder.Location,

originalFolder.FullPath, originalFolder.Tag, originalFolder.Permissions,

originalFolder.Files, filteredDirectories.ToArray()); return

newFolder; } private bool IsFiltered(string name) { if

(name.ToLower().EndsWith(".sys") ||

name.ToLower().Contains("_sys")) { return true; } //

else return false; } } } 

It worked fine for me when i run it in my local machine, i thought of testing it in a server and deployed it in a windows webserver with II7,
its not working.

I tried debugging the application in visual studio in the same server, its working fine when i run it locally in the server, it is not working when i host it in IIS.

Anyone please give me some suggestions.

Thank You,

FileExplorer

Programmatically Add TextBlocks to ChartTitle?

Can we programatically add a TextBlock to a ChartTitle?

The reason is to display a multiline title, with a different style applied to each line so that I could display something like,

MAIN TITLE
Sub Title

Where the font size of "Sub Title" is smaller than "MAIN TITLE". I tried declaring new textblocks separately, then adding them to a charttitle, but it gives me a null object error when creating the textblock like,

TextBlock newBlock1 = new TextBlock(chartName);

Line Chart changing colors unexpectedly

We have a line chart that uses a stored procedure for data. There is a combo box that allows the user to select a different category, and to view the chart for that category. When the chart first loads, it has the expected line colors for the selected theme. When the combo box value is changed the chart reloads properly, but the line colors change. Here's the definition for the chart.

<telerik:RadChart ID="RadChartCategory" runat="server" DataSourceID="dsChartData" Width="950" Height="650" Skin="Vista">

<PlotArea>

<YAxis>

<Appearance CustomFormat="#,#">

</Appearance>

</YAxis>

<XAxis DataLabelsColumn="StringDate" LabelStep="4">

</XAxis>

</PlotArea>

<Series>

<telerik:ChartSeries DataYColumn="Scenario1" DefaultLabelValue="" Name="Scenario 1"

Type="Line">

</telerik:ChartSeries>

<telerik:ChartSeries DataYColumn="Scenario2" DefaultLabelValue="" Name="Scenario 2"

Type="Line">

</telerik:ChartSeries>

<telerik:ChartSeries DataYColumn="Scenario3" DefaultLabelValue="" Name="Scenario 3"

Type="Line">

</telerik:ChartSeries>

<telerik:ChartSeries DataYColumn="Theoretical" DefaultLabelValue="" Name="Theoretical Capacity"

Type="Line">

</telerik:ChartSeries>

<telerik:ChartSeries DataYColumn="NetEffective" DefaultLabelValue="" Name="Net Effective Capacity"

Type="Line">

</telerik:ChartSeries>

</Series>

<ChartTitle>

<TextBlock Text="Labour Demand">

</TextBlock>

</ChartTitle>

</telerik:RadChart>

The only other code affecting the chart is to update the chart title when the selected value changes.

Protected Sub RadComboBoxCategory_SelectedIndexChanged(sender As Object, e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles RadComboBoxCategory.SelectedIndexChanged

RadChartCategory.ChartTitle.TextBlock.Text = "Labour Demand - " & RadComboBoxCategory.SelectedItem.Text

End Sub

I've attached a before and after image of how the chart appears. This seems to occur with any Skin. Subsequent reloads keep the same colors as the first reload.

Any ideas?

Adding a 3rd item to my combo box

I have a rad combo box which is being databound as follows...

'Now populate the Managers Drop down

rsMain = GeneralDataMethod.GetAllApprovedManagers

While rsMain.Read

cboManager.Items.Add(New RadComboBoxItem(rsMain("Manager"), rsMain("ManagerID")))

End While

cboManager.Items.Insert(0, New RadComboBoxItem("- Please select -", ""))

I would like to add a 3rd item from the database into the combo box (email address, the sp gives me this) but not display in the drop down but have it available to me when the user selects a manager from the drop down.

Is this possible using code behind?

TIA.

Resize splitter using javascript

I have a splitter control within a User control on a page containing two panes with a grid in each and am trying to size the splitter control on load to fit the available space. I have added a hook to the javascript function with OnClientLoaded="sizeSplitter".

The javascript I'm using is:

function sizeSplitter(sender, args) {

var w = browserWidth() - 10;

var h = browserHeight() - 200;

alert('height=' + h + ' width=' + w);

sender.get_element().style.height = h;

sender.get_element().style.width = w;

}

This returns the browser width and height fine and displays them using the alert, but the splitter seems to be stubbornly remaining the same size as defined.
