Capture event from HierarchicalDataSource


I have a custom hierarchical data source based on the msdn example (http://msdn.microsoft.com/en-us/library/system.web.ui.hierarchicaldatasourcecontrol.aspx).  An event can be raised in the DataSourceView.  If that occurs, I want to display a message on the web page.

The example is that I have a page with a TreeView control which uses a custom hierarchical datasource.  If the user selects a node that they are not allowed to select, the underlying datasource will throw and error.

I want to capture this and add a message to the page.  The Page_Error event is raised, but there are no eventargs.

Anybody know how to capture such an event? 

An alternative approach, although not quite specific enough, is to set a flag during the datasource load event (indicating the datasource is loading) and test for this flag in the Page_Error routine.

GridView does not show picture in row


OK, what is the problem here?

I do a gridview code that when displaying the information that come from the database is not showing any error at all, but is not displaying the right picture.

The problem,  I think, is that the (Eval("....") is not reading the values that are coming from the DataKeysNames. Due to this the right pictures are not displayed. But in another column, just for testing purposes I was able to display the values from DataKeysNames with the Eval. So I do not know what is going on and to make worse browser is not giving me any error.

So, this is the line that is not processing, reading or executing well:

ImageUrl='<%# IIF( (Eval("TUDTIWasItemUpgraded")) = "Yes",           string.Format("~/Images/ItemUpgradedTo.gif"),          string.Format("~/Images/ItemNoUpgradedYet.gif")    )       %>'     


And this is the complete code for the GridView



Extended MySite: Profile picture uploading to the wrong zone.

I'm experiencing a problem where uploading a profile picture, in a MySite, uploads it to the wrong zone.

What I've done is created one web application and configured SSP to use that same one. As a result, the MySite host location is in that same web application:

Default Zone:
http://my.domain.com  <-- default SharePoint site.
http://my.domain.com/personal <-- MySite host

I then extended that web application to enable FBA & anonymous access:

Internet Zone:
http://extended.domain.com <-- extended default SharePoint site.

Now I"m able to navigate to a user's MySite using the extended URL (http://extended.domain.com/personal)...but when I upload a new profile picture in my MySite... it prompts me for new credentials because it's trying to upload to the Default zone (http://my.domain.com).

I found the following thread that talks about this...but there wasn't any resolution:

What is the best practices when configuring a MySite in an extended web application? How can I fix the situation I'm encountering above?

P.S. I tried to change the MySite Host location (via SSP in the Central Administration)

How to capture ReportViewer Mouse Events


I have a ReportViewer which I'm pulling into a C# WPF project, and would like to be able to capture the row a user clicks on in the reportViewer, but have had no success tapping into the mouse event handlers.   Does anyone know how to accomplish this?  

This MSDN link seems to imply that ReportViewer(winforms) supports mouse click events such as Click, DoubleClick..etc.  http://msdn.microsoft.com/en-us/library/microsoft.reporting.winforms.reportviewer_events.aspx, but I've not had any luck.

If mouse events are not currently supported, does anyone know when they will be, and whether properties such as SelectedItem or SelectedIndex would also be exposed?

Thanks for the help.

We have a MOSS 2007 publishing portal. We are currently facing issues with Picture library created with default picture library template.Whenever we have tried to upload an image to the picture library I am getting "acess denied" error message, though I have full permission to the site level as well as to the library level.I have seen the pictures are getting uploaded and in "checked out" state.It does not show the "edit properties" page on upload and does not even allow the owner of the image to edit the properties, gives the same access denied error message.

I have also tried to check in the image files through the "management and content structure", but the images are not getting checked in. Please let me know the root cause of this and how we can resolve this.

Showing WebCam Video in WPF

Hello all, Does anyone have any good links/references to showing WebCam video in a WPF application? All I need to do is show the video, any capture/manipulation is just candy.  The web sites I've found so far seem to use less then desirable methods (e.g., getting info from the clipboard) or use pre-compiled no-name DLLs. Any help is appreciated!

What pattern do I use to capture an entire C# method definition with all modifiers, method name and

Hello all,Given a C# method named MyMethod, what pattern do I use to capture the entire definition, including modifiers, method name and opening and closing braces, irrespective of bracket styles, given that the method will probably contain 1-n other pairs of braces, embedded or not, etc? In this case, I don't care about the actual method definition, I just need to capture it all in one chunk.    a. public int MyMethod(int parm){            if (...) {            }       }    b. public int MyMethod(int parm)       {            if (...) {            }       }Thanks in advance for any ideas and/or suggestions!

Yet another WPF Screen Capture (with Rectangle) App

  The Plan:         I had plan on adapting the following, which is an old Microsoft sample implementing of a rubberband rectangle for my app               http://support.microsoft.com/kb/314945         To simulate a selectable area to capture i would display a wpf window over the entire desktop and make it transparent. Then i would use the window as the surface on which to do the mouse area selection and draw the rubberband rectangle on the mouse move.  I would then pass the point coordinates of the rectangle to this bit of code to do the actual capture. public static BitmapSource Copy(int left, int top, int right, int bottom) { using (var screenBmp = new Bitmap(right - left, bottom - top, PixelFormat.Format32bppArgb)) { using (var bmpGraphics = Graphics.FromImage(screenBmp)) { bmpGraphics.CopyFromScreen(left, top, right, bottom, screenBmp.Size); return Imaging.CreateBitmapSourceFromHBitmap( screenBmp.GetHbitmap(), IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions()); } } } The Malady:         When i make the wpf window transparent i completely loose it as a surfa
