I have an application using xamWebGrid and in the demo configuration it displays just 357 rows. The data are instances of a simple CLR object of 11 properties of value types: datetime (3), enum (2), string (2), int (2), bool (2).
The empty grid is displayed quickly but the time from setting the data source to displaying the data is ~5 seconds. Initially this is quite confusing for users who are unaware they should wait so press F5 to refresh the page. We've put in a "Loading..." message on screen to inform the user but there does not seem to be an event fired by the xamWebGird once the data is displayed. Without such an event we don't know when to remove the loading message.
So two questions: why the delay? There is not a lot of data. Secondly, is there an event that will fire once the display is presented?
Thanks

Try FastSQLDataSource. It helps when you need faster display of large amounts of MS SQL Server data in your web application using grids, lists and other bound controls. It supports automatic paging and sorting and performs very quickly on large amounts of data It can work almost without coding or sometimes with no coding at all.
The performance of the back end has ABSOLUTELY NOTHING to do with this issue. If you'd read the thread you would have realized the problem occurs when using random data generated WITHIN Silverlight and sourced from any external source.
Your post is just an unhelpful product plug and I hope the moderators remove it.
You do offend me, go hijack another post. The problem is NOTHING to do with the backend. Its to do with the number of objects the grid is placing in the visual tree regardless of the source. In my case the source is Xml but in the test cases provided it is in memory. You can't beat that.
Let me say again - because your posts are potentially misleading others with the same issue - this has NOTHING to do with the backend (and I include the datasource in that definition).

Sorry if I offended you. My topic wasn't about backend. I see the problem in the connection between backend and frontend. FastSQLDatasource resolves that.

Was that your complain? Then FastSQLDatasource will help you out. It is extremely often occurring problem: grid, list, tc. quickly degrade in their performance when data volume increases. That's why I recommend you that helpful tool.
