I have a grid using simple binding method with a collection of business objects. Properties are declared in markup using the DataField attribute. Some properties are in nested objects and are qualified using dot notation. Properties are largely strings with a few dates and numeric.
Deployed app on 64-bit server with an Intel Xeon E7220 with 8 GB RAM running on Windows Server 2003 R2. Using 64-bit .NET 2.0 framework. When deployed, the binding of 100 rows with 40 columns takes about 700 ms. This seems high to me.
I assume the object binding is achieved with reflection. Are there optimizations in place? What's the best performing method of binding data to a grid?

Hello James,
How fast will be data binding in general depends what column you are using in RadGrid. For example if you use GridDropwDownColumn it will take a bit longer that using GridBoundColumn. Of course binding time will depend of that features are enabled in RadGrid.
However I am not sure that 40 declarative columns with 100 rows will took 700ms to RadGrid to bind using simple binding. Can you tell how you are detecting this time? Is the time for building the business object collection included in it?
