Hello,
To the extent I understand your concern, you would probably need to invoke C1DataGrid’s CollectionView.Refresh method after you are done modifying the data in other thread.
I have attached a demo sample for the same. Could you please try running it at your end and share your observations. The application uses BackgroundWorker to update the DataTable to which the grid is bound.
Hope it helps !
Thanks,

Thanks, Great Sample!
But my problem that i have one DataTable that all the time Update RT very fast and with a lot of Changes in other class, ist not possible every change to send refresh.
and the user can create multi Grids that connect to one DataTable (diffrent Filter & etc’) so its very dymanic, and the cell is Update anyway, only the style is not update, there is no way to create update Style on TextChange in the textbox? or something like that?

Hi,
In that case, you may invoke Invalidate method of C1FlexGrid just after updating the data in datatable. This would make to re-create visual elements.

thank, i found a way to fix this out.
but now i found one more thing…
why after the data update the sort column not update the data sort?
sample : if i sort [Price] column, and the data update to a new Prices the data still sorted by the old prices and not the new Prices.
i check in your sample too :

wait for reply, Thanks

Hi,
Did you try this behavior with the sample I shared earlier. While running my sample I could not replicate that behavior at my end. See attached movie showing the behavior at my end[using Invalidate method].
Could you please check the attached sample at your end.
Thanks,

Hi,
This is probably a collection issue, which that sample application uses. However, to be sure I would need some more time.
Meanwhile, I would suggest you to try setting IsLiveSorting to true. For details kindly refer: https://docs.microsoft.com/en-us/dotnet/api/system.componentmodel.icollectionviewliveshaping.islivesorting?redirectedfrom=MSDN&view=netframework-4.7.2#System_ComponentModel_ICollectionViewLiveShaping_IsLiveSorting

Hello,
I am modifying the article application to make its sorting work as you desire. I would share the modified sample here soon.

Hello,
As we were understanding earlier, the limitation is related to the Collection being used, team has confirmed it, only DataTable can fit this request. Therefore, we have modified the article sample accordingly and attached here for reference.
