Asked On January 19, 2007 12:47 PM

Hi,

I emulated the Market Simulation Syncfusion project but instead of binding the gridgroupingcontrol to a DataTable I bound it to a custom class implenting IDictionary and IListSource. I found that updates to any values in the custom class were not reflected automatically in the grid and cell blinking did not take place. I had to invoke gridgroupingcontrol.Refresh() instead of Update() to force the graphical updates, which is substantially slower.
Is there any efficient way to resolve this? Thanks.

Hi Yong,

Thank you for being patience.

Currently we are trying to reproduce the issue in a sample to debug it. Is it possible for you to update us a demo sample on this issue, it would help us to debug your issue at the earliest?

Have a nice day.

Best regards,
Madhan

Hi Madhan,

I've attached a solution file which is a simplified version of my current project but highlights the issue nevertheless. Only calling the gridcontrol.refresh() causes the grid to update as modifying the Datasource directly does not trigger any events. Please advise on an efficient solution.
Thanks.

Hi Yong,

Thank you for being patience.

This can be achieved by triggering the ListChanged event of the grid in fake. For this, the SimulateListChanged method of the Table is called with the corresponding ListChangedEventArgs instance. The following is the modified sample, please try it and let us know if you need any further assistance.

Kindly let us know if you need any further assistance.
Have a nice day.
