  3. Sorry for bumping this, but I realized I posted this late on a Friday so I don't know how many people ended up seeing this.

  6. Here's an update on how I resolved this problem:

    Basically I just removed the "selected" class from the cell that I wanted to distinguish and added my own custom css class to it. Here's what the...

    Thanks, that did the trick.

    Since cells can only be colored once at a time, it wasn't too hard to remove the color class like para suggested. I just did an indexof the different color class names...

    I'm in need of a timer to accomplish scrolling a grid. In case you're not familar with what a timer is, basically it needs to perform some block of code on a given interval, but not stall the rest...
  12. Well hey, there we go.

    For some reason I thought initEvents was called by default, but I guess not.

    Thanks.
  13. For some reason I can't get a context menu to display on my custom EditorGrid. The onRowContextMenu method is never called. Here's what I'm doing right now:

    Sorry to bump this thread, but I could really use some help on this.
  16. I found that I was calling grid.view.refresh() each time in afterEdit, which was the main reason for the slow down.

    Additionally, I found it faster to manually update the records and then do a...

    I'm trying to implement a method for selecting multiple cells in an EditorGrid by dragging your mouse. I already have most of the code for doing this, since it works by using shift and the arrow...
  20. Whoops, I don't know why I didn't think of that.

    Well, it's working now, except for the fact that render only occurs when a row gets changed. This means that when I select a cell, render doesn't...
  21. Thanks, but my problem is more that I'm having trouble actually getting a reference to the grid (from there it's pretty straightforward). I've been looking through some of the scope tutorials, but...
  22. Thanks for the reply.

    I think a custom cell renderer like that would work, although I can't figure out how I would pass in the argument of what the selected cell from the SelectionModel is. If...

    Hey does anyone have an example of Live Clipboard being implemented with a grid? I'm curious to see how it was coded and how some things were implemented from a UI perspective.

    Thanks.
