In Windows XP, if IIS was installed after Visual Studio was installed, then you would have to run command aspnet_regiis –i in order to make Visual Studio work with IIS.

It is a common requirement to validate different fields on an ASP.NET form based on different conditions, for instance, if user selects “Other” from a Drop Down List, then he/she will be required to type in something in a TextBox control. It can be done easily in code behind, but can we accomplish the same task at the client side? The answer is yes. We can use ASP.NET validation’s client API to conditionally enable/disable validators.

In ASP.NET, the style of GridView is usually controlled either by using a CSS file or by using a skin file and in many cases this works well, but what if we need to style the GridView as follows: Of course it can be done in code behind by looping through the GridView rows and applying different CSS class for each row. It needs at least a “For” loop and a calculation of the reminder […]
jQuery? What? jQuery is a powerful JavaScript library which aims to reduce the time and effort for writing JavaScript code, and to support Unobtrusive JavaScript. Take the following line of code as an example: $(“table tr:nth-child(even)”).addClass(“yellow”); The above line highlights every other row in a table with a yellow color (assume you have a style called “yellow”). If you use raw JavaScript, it may take you dozens of lines of code to accomplish the same […]

Use a DataList control to display the thumbnails: <asp:DataList ID="dlThumbnails" runat="server" DataKeyField="Name" DataMember="Name" RepeatColumns="3" Width="100%"> <ItemTemplate> <asp:Image ID="imgThumbnail" runat="server" /> </ItemTemplate> […]

In Part 1 and Part 2, I talked about how to use Cool DHTML Tooltip II to replace ASP.NET built-in tooltip for better user experience. However, you may notice that if you use Cool DHTML Tooltip II in an AJAX ModalPopup, the tooltip is displayed underneath the ModalPopup. It turns out that when the AJAX ModalPopup is generated, its z-index is always reset to 100001 so the popup window is always on top of other […]
