How can i refresh datagrid

Can you tell me how this is done? I can tell you that requests are sent to the database. I can see the statements being print.

Btw: I created a new application and the exact same code works in there. Question is how I can fix my already existing one?

I have the same issue as well. I have a grid that I refresh on a timer that updates the grid data data source. Only add and deleted records refresh. Eventually after enough time goes by the records will get updated. So I did some more testing and looked at the data. The grid data is not showing the correct data unless there is a new record added or a recorded removed.

I have debugged the grid load event and it is not getting the current data for records already bound to the grid. I am getting the data in the gridload event and have a timer that calls the grid0. Here is the grid loaddata event: protected async System. WriteLine "grid0. Reload and grid1. Reload ;. I had issues posting the razor so I attached it as a zip. Not sure why is not working for you. I've modified this demo with the following code and the LoadData method is called every 5 sec:.

To me, it looks like the whole loaddata event has caching which prevents some functionalities. For example the pagination does not work for me too when using the load data event. Grid is showing the pages, but the pagesize is not considered and all records are presented. This issue does not appear to be resolved and I'm dealing with the exact same problem.

From my testing, this seems to be a lot faster than calling GetDefaultView as some of the other answers recommend. GetDefaultView myGrid. Refresh ;. Rosado D.
