Why templating the content of the UpdatePanel?

Many ASP controls use template for their content (theGridView being a good example). TheUpdatePanel has aContentTemplate property that, as the name suggests, contains the content of the UpdatePanel.

Yet, since the UpdatePanel is not a repeater control, I do not grasp (as a consumer of the ATLAS library) the interest of templating the content of the UpdatePanel. Does some has an idea why a ContentTemplate is used instead of the regular control children?

Thanks in advance,

hello.

i'd say that a template let's you have complete control over the content of the updatepanel. if you had a property of another type, you'd only be able to use elements of that type (or of a derived type)

ThePlaceHolder is not templated and but can include any element (as long as they inheritControl which is not a real constraint). My question can maybe be rephrased as "Why did the UpdatePanel not follow the PlaceHolder design pattern?".

hum...how about designer integration? i'm not sure because i really don't use the designer, but can you drag-n-drop controls from the toolbox into a placeholder control?
