Frozen and scroll set to true #424

Closed littlesimon closed 6 years ago

littlesimon commented 6 years ago

Hi, I saw there is some limitation when using frozen columns and scroll= true http://www.trirand.com/jqgridwiki/doku.php?id=wiki:frozencolumns Is this still the case with free jqgrid? Thank!

Many parts of frozen columns implementations is improved in free jqGrid. For example, one can use inline or cell editing. The performance is essential improved too. On the other side virtual scrolling (scroll: true or scroll: 1) isn't supported in combination with frozen columns. I don't recommend to use virtual scrolling at all. It brings a lot of disadvantages. I don't removed virtual scrolling, but it's probebly the only feature of jqGrid, which I don't recommend to use neither in old jqGrid (version <=4.7) nor in free jqGrid.

Thank for the anwser. Does virtual scrolling will be supported for frozen columns in futur release of free jqgrid?

OlegKi commented 6 years ago

No, there are no plans to support virtual scrolling for frozen columns. Virtual scrolling have many disadvantages in the current implementation. I don't remove the feature only to simplify upgrade from old versions of jqGrid. Virtual scrolling will be not developed in the future till the implementation will be full rewritte, but I have no time to do that in the near future. I don't recommend to use virtual scrolling at all and to use standard paging instead. You need just set rowNum option to some small value, so that the user can see the page on the screen (something between 5 and 25 typically) and to add either toppager: true or pager: true option or both.
