Upgrade DXperience suite to 9.1.4

Hi all.

I was very pleased to see the installer experience from Developer Express. They added an option to upgrade the current installation thus avoiding the uninstall-install process. This is way faster than with previous versions.

Download Developer Express tools in the Client Center for subscribers and for tryouts the trials link is here.

Happy installations!

News: Silverlight DataGrid Control – Available Free-of-Charge

The Free Editions of DevExpress AgDataGrid Suite in not just a "preview" of what is possible with Silverlight. It was developed to fully exploit the power and flexibility of the platform and ships with the following advanced features:

  • Data Grouping against multiple Silverlight Grid columns
  • Data Sorting against multiple Silverlight Grid columns
  • Comprehensive Summary Computation support against multiple Silverlight Grid columns
  • Column Movement
  • Column Resizing
  • Column Auto-Width
  • Row Editing
  • Row Preview (with animation)
  • Template Support (for cell content, cell editing, row preview and headers)
  • Auto Height Support for cells, headers, and totals.
  • Virtual StackPanel Row Container (simply means we are able to handle an unlimited number of rows)
  • Focused Row and Focused Cell
  • Multi-Row Selection
  • Cell Text Wrapping
  • Vertical/Horizontal Lines
  • Multiple column types/editors

Beyond the features we’ve listed above, the AgDataGrid will ship with the following capabilities:

  • Smart UI Element Management
    AgDataGrid implements a smart loading and re-organization of the grid’s inner UI elements to provide smaller control load times and faster data operations.
  • Designed for Future Performance Enhancements
    Silverlight is all about client-side technology…But if client/server interaction will be implemented in future versions, our grid is ready to delegate data processing to the server side and thus boost application performance.
  • Higher-Level abstractions
    With our unique measurement routines you don’t have to think in terms of pixels – which you do with the standard Silverlight grid. Just like other advanced controls for older platforms, you simply specify styles and fonts and all element sizes are automatically modified.
  • Full Animation Support
    It’s hard to imagine any Silverlight control without compelling animation effects. Though the standard Microsoft Silverlight grid control’s architecture doesn’t support them, AgDataGrid fully supports animations for group row expansion, preview row display and other operations.
Commercial Version Available

DevExpress offers an extended version of its free Silverlight Grid, including features such as end-user data filtering, sorting of group rows against corresponding summaries and multiple cell selection. To learn more and download a free trial version, visit the following page.

The ASP.NET Capsule #10: N-Nested Grids with Developer Express ASPxGridView

Hi all.

I just finished my newest video on how to create an N-Nested Grid with Developer Express ASPxGridView. It’s a pretty simple process but somewhat unknown so here is a tip on how to get started with this, ohh and did I mentioned? You just need 1 line of code per each nested ASPxGridView.

So, here it is. Enjoy! And check the attached project so you can play with it.

The ASP.NET Capsule #8: New video on Telerik’s RadGrid + RadToolTip Manager

Hi all.

Check out my new video on using Telerik’s RadGrid.

By using the RadToolTipManager control we can provide our users with more information by just hovering above an item on the page. We are using the RadGrid object to show orders information and then showing the details of the order when you hover above the order number.

One of the things I didn’t mentioned in the video is that when the RadGrid in the tooltip gets too big you have to scroll the window down and then loose all the good experience. However, with RadGrid is very easy to avoid that (see the attached sample for one solution with the ASP.NET Panel).

Just modify the following settings in the User Control RadGrid to enable scrolling in the grid and not in the window:

ClientSetting –> AllowScroll = true
                        UseStaticHeaders = true
                        ScrollHeight = 250px

Errors on Microsoft® Silverlight™ Streaming by Windows Live™

Hi all.

I’ve been trying since yesterday (unsuccessfully) to upload a video to the Silverlight Streaming website

I’m always getting this error in IE8, Firefox and Safari doesn’t even work:

uncaught exception: Error calling method on NPObject! [plugin exception: System.Security.SecurityException: Dialogs must be user-initiated. at System.Windows.Browser.ManagedObjectInfo.Invoke(ManagedObject obj, InvokeType invokeType, String memberName, ScriptParam[] args) at System.Windows.Browser.ManagedObject.Invoke(InvokeType invokeType, Int32 memberID, ScriptParam[] args) at System.Windows.Hosting.ScriptingInterface.InvokeScriptableMember(ManagedObject obj, InvokeType invokeType, Int32 memberID, ScriptParam[] args, ScriptParam& pResult) at System.Windows.Hosting.ManagedHost.InvokeScriptableMember(IntPtr pHandle, Int32 nMemberID, Int32 nInvokeType, Int32 nArgCount, ScriptParam[] pArgs, ScriptParam& pResult, ExceptionInfo& pExcepInfo)]

Anybody experience similar problems?

NOTE: Apparently this is provoked by the installation of a different version of Silverlight. I installed Silverlight 3 yesterday and that caused the problem. Reinstalled Silverlight 2 today and everything is working fine now.
