Filtering

[Prashant]

I need some explanation beyond the two examples in the documentation. I am just not understanding filtering. Not true I understand the concept of filtering I am having problems with implementation.

I have a basic grid which I am filling with data from persistent storage (i.e. in the Current Session). On Page_Load I simply assign the storage for a particular table to the grid data source and bind. Simple. When sorting and paging happen I basically do the same thing. But filtering. That is a whole other ball game! I do not see an Event that I can use to rebind the data. I am assuming that the Grid or TableView handles the actual filtering and I do not need to provide any sort of filtering function.

The filtering that is offered is more than adequate for my needs I just need to know what I have to do to get an implementation going.

Thanks,
Doug

Hello Douglas,

The issue occurs because you are binding the grid using Simple data binding technique. If you are using any advanced feature in grid(like paging,filtering), then a better approach is binding RadGrid using "AdvancedData binding" using NeedDataSource event.

 

For more information about this can be available here.

Thanks,

Shinu,
Thank you for the response. When using the Advanced method, am I, as the developer, no longer responsible for putting handlers in place for OnPageIndexChanged, OnPageSizeChanged etc? This is handled by the NeedDataSource event? If this is true then this is actually quite a bit easier as only one handler needs to be built. Am I correct here?

Thanks,
Doug

Hi Douglas,

Yes, you are correct - just go along the lines of Advanced data-binding for the grid and it will handle the sorting/paging/filtering commands by itsefl.
