Auto-complete ComboBox with WCF Service and RadControls for Silverlight
Sometimes we need to load very large amount of items in a ComboBox and let the user select one of them. Usually in those cases the ComboBox allows typing in order to auto-select the items, that contain the text in the control. Such scenarios are possible with RadComboBox for Silverlight and now I will show you a simple application, that demonstrates what I think is a better practice for the implementation. We want to put all words from the English dictionary of RadSpell for ASP.NET in a RadComboBox for Silverlight and allow the user to select one of them, that will... -

Easily implement AutoComplete in your application
It is considered a good interface design practice to make it easy for the user to provide input. One of the ways to do this is to anticipate what the user is trying to enter and provide them with options or complete the entry for them. For example, if I type in a popular browser a web address containing the letters "tel" I will see several options made available to me, as shown below. The key is to have the ability to make a reasonable guess at what the user is trying to input. This is particularly helpful for values that...May 27, 2021 2 min read -

WPF RadChart 3D Labels and Formatting
Today I decided to break the lengthy silence on my blog by writing about two of the features that will be included in the Q3 SP1 (mid-December), namely labels in 3D and labels formatting. Here are a couple of screenshots: As the screenshots clearly show, the labels are simple 2D controls instead of 3D objects. As I wrote in an earlier blog post, that guarantees the labels will be readable at all times, and not hidden by other 3D objects (always on top of the Viewport). If you are interested in the implementation details, you can refer to the aforementioned blog...May 27, 2021 1 min read -

Tip of the day - Modal Dialogs
When we have a running application and we want to show a modal dialog window what we generally do is more or less the following: var window = new MyDialogWindow(); window.ShowDialog(); Doing that works great - the dialog window shows and is modal. It has just one tiny defect - if you switch from the running application to another one (i. e. using Alt + Tab) and then come back to the running app the modal dialog window is not showing and the app is inactive. The solution - just assign the parent window to the Owner property of your modal dialog window : var window = new MyDialogWindow(); window.Owner = this; window.ShowDialog(); ... -

Hide duplicates in a column
In some cases you might want to hide duplicates in a single "column" - for example if you group by a field, it would be nice to present the data in a more clean way. -

Can your grid control do this? Part II
.csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; /*background-color: #ffffff;*/ /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } In my previous post I told you about the new interesting feature in RadGridView for WinForms - Row Layout customization. I also promised to provide some additional details about this feature, so here they are. The view definition in RadGridView not only changes the row layout, it specifies the behavior and the appearance of the grid. All view definitions implement the IViewDefinition interface and you could create your own definitions, if you wish. To change the default view definition in RadGridView you need just to set the ViewDefinition property: this.radGridView1.ViewDefinition = myViewDefinition; We have included three different view definitions in our Q3 release. They are: TableViewDefinition,... -

IE7 Scrolling Is Slower If Hover Pseudo CSS Classes Are Used on the Page
This has been something like a tale of the unexpected for me. A client recently reported a problem with scrolling being slow in IE when the mouse wheel is used. It took about two afternoons of testing different scenarios and head scratching, and this is where we got: it seems that if a :hover pseudo CSS class is used on the web page, scrolling in IE7 becomes slower, even if the CSS selector, which contains the :hover pseudo class does not select anything, i.e. the CSS rule is not relevant to any of the web page elements. The longer the page, the...
