Hi,
I've got a grid containing various columns from several joined tables. Also, the client requested Excell style filtering which means that for each column I'm generating a custom filter control in the header to mimic Excell (basically combobox checklist dropdown).
Now I also require updates to be possible for a few fields in this set, basically that shouldn't be too much of a problem. Let the update column generate and use the command events.
However, as I mention above, binding the grid takes some work and therefore some time as well. Clearly you can imagine that it's not desireable for any user to have to wait for the entire process to run each time an itemcommand is fired.
Both 'edit' and 'update' will trigger the selecting events for each datasource. So the whole grid gets bound (selecting event of the main datasource/NeedDataSource event) and the combobox filters also get rebound (selecting event of those controls' respective datasources).
So ... shouldn't there be some way I can put a row in edit mode w/o rebinding the whole thing?
Actually it's sort of the same thing for the filtering. Can I not bind the data to the grid w/o rebinding all the custom filters?

Hi Kevin,
One possible option in this case would be to perform batch updates, as shown in this topic:

Additionally, you may be interested to review the following code library:
I hope this information helps.
