If you have an ASP.NET Web Forms page with multiple UpdatePanels and multiple UpdateProgress controls, sometimes you may want one or more UpdateProgress controls associated with a specific UpdatePanel, and one or more UpdateProgress controls that have no association with an UpdatePanel so are shown when any UpdatePanel is updated.

Can't change the Visible property of a control in ASP.NET Web Forms?

by John Avis | March 23, 2015

If you come across a problem where you set the Visible property of an ASP.NET control to true in a code behind file, but even when you debug it still shows the value as being false then the problem is most likely to be that the control is inside another control such as a Panel or PlaceHolder that has its Visible property set to false.

by John Avis | January 27, 2015

I recently experienced an issue with an ASP.NET Web Forms page with various UpdatePanels. The page has two DropDownLists, the selection of one results in populating of possible values in the other, and the selection of the other results in enabling of a Button. Then if the Button is clicked the user is redirected to another website, based on their selection.

Using SqlDataReader NextResult to improve performance

by John Avis | July 31, 2014

On database-driven websites it is commonplace to execute multiple database queries to generate just one page. For example, on the home page of an ecommerce website you might get a list of categories, a list of banner advertisements to display, a list of featured products, and a list of top selling products. I investigate whether it was more efficient to put these multiple queries into one stored procedure and use the SqlDataReader's Next Result method to get the data all in one go.
