Grid Selectionmode:'checkbox' | disable when no records in grid Posts

Spectator

Hi,

In my grid, I had set the selection mode as ‘checkbox‘ so the individual row selection/check all/un-check all can be allowed, if the grid contains atleast one row.

In some cases, I load the grid with no data’s i.e. zero row. When I click the columnheader checkbox, I’m getting an error in IE as “Object expected” and Mozilla as “L is null”.

Requirement:
If there are no rows in a grid, i want to disable the column checkbox i.e. columnheader checkbox.

Can anyone suggest me a solution?

Looking for a prompt response.

Thanks,
Senthil

Hi Senthil,

Do you use jQWidgets 3.2.1? How can we reproduce that? I am asking because we were not able to replicate the described behavior with the current version.

ex:

Hi Peter,

The version I’m using is 3.1.0.

I’ll update the library version and try the same.

Thanks for the information.

Cheers,
Senthil
