I've done some tests and there doesn't seem to be any errors. Produce an example that throws you this error and attach it so I can review it

 

[spiroskaras]

thanks ,my example in attach file

 

[Star-Dust]

Sorry it doesn't access the DB and so I can't test it. Furthermore, ShopListView1.Invalidate is missing after inserting the data that would serve to update the list.

Are you sure the error is not generated in accessing the data rather than from the ShopList?

Produce an example with some local data, even randomly generated so I can examine the problem

 

[spiroskaras]

hello,
here is a new sample
3 buttons with different lists,if you scroll down a list and then you change list you produce an error

 

[spiroskaras]

sorry i will resend attach

 

[Star-Dust]

It doesn't throw me any errors. Does this example you sent to you throw error?

maybe you modified the library?

 

[spiroskaras]

hello ,yes
no modification, the error occurs when i scrol down the list and then i change list
if you dont scroll down list ,in change list is not throwing error

 

[spiroskaras]

oops
thank for your replies

 

[spiroskaras]

is an untouched sample ,i only put some buttons in order to change lists

 

[Star-Dust]

is an untouched sample ,i only put some buttons in order to change lists

Yes I was referring to the library not the example that you can change as you want.
Then the problem would be that you clear the list while still the animation is displaying and it throws the error.
Download the latest version. Correct the bug
