How to have an infinite horizontal scrolling?

[Bahram]

Hi there,

 

I have a requirement which is implementing a horizontally infinite scrolling on a GridView. Basically, I want to be able to add new columns to my GridView and see them as I am end of scrolling(either side). I know how to add and bind new columns to my GridView at run-time, but I don't know if there is any event or trick that I can use to detect if I am end of scrolling or not(so I can add new columns...).

Can someone please help me with this?

 

 

Thanks,

Hi Bahram,

What you can try is to get the ScrollViewer inside the RadGridView and subscribe to its ScrollChanged event. Inside the event handler, you can check if the ScrollableWidth of the ScrollViewer is equal to the e.HorizontalOffset property from the event arguments. If yes you can add a column to the RadGridView. To get the ScrollViewer you can use our ChildrenOfType<T>() extension method. 

I have prepared a sample project which demonstrates this approach.
