Dave61 · Apr 11, 2016

I was planning to use the gridview as a grid of buttons for the user to select a task. The interface looks good cosmetically and the person using it is happy with it apart from 1 problem:

The grid only takes up half the screen. When the user clicks on a button/image then some more Views appear to be filled in and finally a Send button is used to complete the task and clear the extra views until the next button/image is pressed.
I cannot find a way to 'highlight' the button/image that has been pressed in the grid. Ideally I would like either a highlight border around the selected image or all the non-selected images to be 'greyed-out'. Are either of those possible or is there another way that anyone has found to highlight the selected image?

As an alternative to that, I thought that I could have the Activity title show the name of the button pressed as a reminder. I use:
gridview1.ShowFromAssets
to load the grid from a list of files in the Files folder. However, I can't see any way to retrieve the filename (which has a good description of the task if I just trim off the '.jpg' from the end) from the selected item. All I can get is the Position which shows the number of the button being pushed. Is there any way to get the original filename without me having to include an extra list or had code a list?

Thanks,

Dave

Thanks lonely... another tedious problem is that:

if I use the text, when i scroll down and after i return in the top of the items, the text change wrong and displays the text of other items. If I repeat the procedure (scroll down and scroll up) the text changes again with text other items yet....

Can you fix this?

THANKS!!!

i support this, @lonleystar did you have any update of why the error occurs?

aidymp · Aug 8, 2016

Just come across this today, and I cant initialise the gridview using 3.60 of the lib. as I see a few others have found. i can however use 3.50 but I was hoping to use the features of 3.6! Any information/news of why it wont even initialise?

Thanks
