Hi,
I have a GridView that has one column that I fill with an alternating "Title
Row" then "Details Row". The Title row has a button that I use to hide it's
corresponding details row that is underneath it for users to collapse detail
rows leaving the title row visible. The button can be clicked again to show
the details.
This used to work great using a DataGrid but when I upgraded it to a
GridView I experience the following problem:
When clicking the button it hides the details row as expected but when
clicking other buttons, the previously hidden details row show. They do not
retain their hidden attributes.
Can someone help me with this? THANKS!
Here's the code:
