I have a datagridview which displays customer orders. I have implemented a search panel with various options to narrow down the subset of orders by applying a string of filters to the bindingsource.
I have also added an unbound checkbox column to allow the user to select/deselect orders along with a Select/Deselect All button.
My problem is this; if i select some orders then chagne the filtering the checkboxes are all cleared. I Obviously i dont want to have orders selected that were removed by the filter, but is there any way to maintain the checked state of the orders that remain in the subset?
I realise i could store the checked orders in a list then loop through the rows re-checking those still visible, but i'm concerned about the computational cost and speed factors in doing this with a large dataset. Anyone know a better way to go about it?
