About the column pinning effort

This fork adds pinned columns to slickgrid. There was a fair amount of code rewrite involved. Work in progress.

Pinned Column Examples

Renaming

To support pinned columns, we slice up the grid regions, and try to be very clear and consistent about the naming. This is because having a left and right region for every content area makes a flat list of naming conventions multiply quickly. I also was uncomfortable with the proliferation of names like header, headerScroller, and headerRow.

Two big changes:

1. UI components are labeled top to bottom by what control they are.
2. headerRow renamed to subHeader. The old name was confusing. TODO: This means the name of related options has changed, too.

Canvases always represent content size, viewports always represent scrollable regions.

Every element has side [0] and side [1], for left and right.

Other Changes:

Adds some methods that make it more performant to do auto column resizing and exposes some methods that make it easier to work with multiple grid instances and pinned columns.

• grid.updateColumnWidths(columnDefinitions)
  • Using this method improves the performance of changing the width of one or more grid columns by a lot. The existing API only allows for a whole grid redraw, which can be very slow. Pull request with notes here. Use cases for fast column size adjustment may be: auto-sizing columns to fit content, responsive sizing cells to fill the screen, and similar.
• grid.getId() lets you get the uid of the grid instance
• grid.isGroupNode(row, cell) lets you check if a node is part of a group row
• Triggers existing event onColumnsResized when you change the column widths
• Triggers a new event onColumnsChanged when you set the columns
• Exposes the existing method grid.setupColumnResize, which allows you to re-enable column resizing if you're manually screwing around with the headers.
• Some new options on setColumns and resizeCanvas let you prevent some of the expensive calculations, useful if you're doing them yourself externally.

Adds antiscroll compatability to enable a uniform, OSX-style scrolling experience across browsers. Enable antiscroll by including the antiscroll library on your page, and passing the useAntiscroll: true option to your SlickGrid instance. By default we don't show scrollbars until the user begins scrolling (to mimic the way OSX does it); to change that behavior, you can set the showScrollbarsOnHover option.

Adds skipPaging option to prevent slickgrid from paging when user keypress take the user off the current page. Instead, up & down keypresses reveal one new row at a time.

Exposes grid as the final parameter of the asyncPostRender callback. Signature is now asyncPostRender(node, row, dataRow, column, grid)

Adds appendSubheadersToContainer option to allow injecting the subheaders straight into the root of the container, which is useful for absolutely positioning them relative to the container (eg. for a fixed footer). Note: this feature does not support pinned columns.

Adds scrollbarSize and maxSupportedCssHeight options. Pass these in if you know their values beforehand to avoid layout thrashing on load.

Adds the withTransaction(fn) method on Slick.Dataview as a shorthand for beginUpdate() and endUpdate().

(Original Documentation) Welcome to SlickGrid

UPDATE From Mr. Leibman: March 5th, 2014 - I have too many things going on in my life right now to really give SlickGrid support and development the time and attention it deserves. I am not stopping it, but I will most likely be unresponsive for some time. Sorry.

Find documentation and examples in the wiki.
