call to refreshfilterrow error when grid is created in hidden parent

[KaddathParticipant]

Hi!

I hope I don’t bother you with my bug reports, but I feel it’s better to report them, even when I can use a quite simple workaround to prevent them..

In our code, grids are sometimes created in a tab that is still hidden at that moment, and actions are performed on them “in the background”. So far they behave great, rows can even be selected and events triggered (even if as I’ve noticed with this bug, the grid is not visually initialized yet; actually I had trouble to find that being hidden was the condition for the error to happen).

So, when the grid is an a hidden div, and is created with showfilterrow: true, so far everything is OK. But if a call to jqxGrid('refreshfilterrow') is made while still hidden, this error happens:
“TypeError: this.columns.records is undefined”

You can try it here: https://jseditor.io/?key=e48ef582f66911e9a73300224d6bfcd5
Once the parent div is shown, the error doesn’t happen.

Thanks by advance,
Kaddath

Hello Kaddath,

Could you clarify it?
What is your final goal?
Because this is a refresh method and it makes transformations and does actions over the existing elements but if you set display: none it is difficult to do this.
Please, take a look at this workaround.

Thanks for the answer,

I’ll try to explain it simply, I can’t really share all the code because it’s really long: we have a wrapper class for grids that automatically plugs to a data set component with hidden “system fields” (that the data set uses internally). On creation, filters are added to these system fields and by default, our function to add filters refreshes the row (which seemed a logical thing to do, because these system columns are not always hidden -our debug mode-).

So it didn’t happen until now, but grids can be in a tab that is created but still not shown. We can’t use this workaround because that would imply to show the tab (select it), however I used another one which consists in an extra parameter to our add filter function, to optionnaly not refresh the row when the grid is in creation.

If works so far, but it just seemed to me better idea to solve the error at the source, and add an extra test to refreshfilterrow, something like if(!this.columns.records){ return; } so that there is no error in the console.. That’s why I reported here.
