Hi everybody,
Imagine the following scenario:
One System.Web.UI.UserControl (UC1) with 2 drop downs and one button "Filter" One Webform with (UC1) and a GridView, basically the UC1 provides the options to the user to restrict (filter) the grid.
The user changes the drop downs and then uses the Filter button to filter data (grid) that is the correct behavior. Now imagine that the user plays with the dropdowns, but he doesn't want to apply the filter and after he chooses to walk to a different page, that action will cause a postback of data, and the dropdown selections will be effective applied due to be changed by a previous use in the interface.
The question is how can i avoid the postback (or ignore it) when postback is not fired due to the action of the "Fire" button ?
I think the solution probably need to be client side, because it's not a problem of the grid filtering data based in the options, but also a visual consistency, when you do a postback and the page is rendered to the client the drop downs should reflect the filter applied.
Any ideas, thoughts ....
Thanks all for reading.
Regards,
TP
