.NET GENES

A control developed by: Stelios Alexandrakis which I found it cool is a combobox with checklistbox as the dropdown item. After fixing a few bugs, I integrate the feature of multi-highlighting based from the previous post on customizing CheckListBox control: CheckBoxList Multihighlight . Here's some screenshots to illustrate each of the custom controls.

If you want to customize the CheckBoxList control to support multi-highlighting (each checked item is highlighted), you can simply override the OnDrawItem() by adding Graphics statements as shown below: Here's an image sample of the extended CheckBoxList control: Code: protected override void OnDrawItem(DrawItemEventArgs e) { int index = e.Index; if ( this .GetItemCheckState(index) == CheckState.Checked) { string text = this .Items[index].ToString(); Graphics g = e.Graphics; Point point = this .GetItemRectangle(index).Location; point.X += estimated_point; //estimated point is a value you may set manually //background: SolidBrush backgroundBrush; backgroundBrush = reportsBackgroundBrushSelected; //estimated point is a value you may

Hi! When running an asp.net app that includes an ajax custom extender control, a javascript alert pops up message "EXTENDER is undefined". Sample error message: CustomExtenders.DisabledTextBehavior is undefined where: CustomExtenders.DisabledTextBehavior is Namespace.Type After troubleshooting for several hours, I came up with the solution: 1. Download Ajax Toolkit Stable Release for the specific .NET Framework.  I tried versions for September release and it's not working. 2. Replace code: CustomExtenders.DisabledTextBehavior.registerClass( 'CustomExtenders.DisabledTextBehavior' , AjaxControlToolkit.BehaviorBase); To CustomExtenders.DisabledTextBehavior.registerClass( 'CustomExtenders.DisabledTextBehavior' , Sys.Extended.UI.BehaviorBase); Note: AjaxControlToolkit.BehaviorBase is used in previous versions of AjaxToolkit. Cheers!

Hello! The previous version of ExtenderControlBaseDesigner does not require T as parameter. However, in recent versions you might notice that the class is declared with T. Here's a sample declaration: AjaxControlToolkit.Design.ExtenderControlBaseDesigner<T> T means AjaxControlToolkit.ExtenderControlBase. In order for the Custom Extender Designer to work, supply the T with class that inherits the ExtenderControlBase. This sample class inherits the ExtenderControlBase: public class CustomPanelExtender : ExtenderControlBase { //your code goes here.... }

When adding ajax extenders to asp.net server controls using Smart Tag, you often encounter an issue such as Show Smart Tag is greyed out/disabled. The best thing to do is to use the latest stable version of AjaxToolkit. And then, reset the toolbox. Sometimes, you have to close the Visual Studio IDE just to make sure. IDE Version: Visual Studio 2010 Professional Ajax Toolkit Binary: AjaxControlToolkit.Binary.NET4 (Stable Version) Cheers!

Hi all! On a Windows 8 environment where in you have VS 2010 installed and you want to add SQL Server 2012 to your list of software, install first VS 2010 SP1 to make changes to setup configurations. Cheers!

The function below retrieves the top Freight amount specified by date range values use CompanySales IF object_id (N 'dbo.GetTopFreightValueRange' , N 'FN' ) IS NOT NULL drop function GetTopFreightValueRange go create function GetTopFreightValueRange ( @startDate nvarchar(50), @endDate nvarchar(50) ) returns decimal(10,2) as begin declare @ result varchar(50) set @ result = ( select FreightAmount from dbo.Orders where CONVERT (VARCHAR(10), ShippedDate, 120) >= @startDate and CONVERT (VARCHAR(10), ShippedDate, 120) <= @endDate ) return @ result end go -- select dbo.GetTopFreightValueRange('1996-11-01','1996-11-30') as freight_value;
