Allow beforeEditCell to abort edits by returning false. Since editing is turned on for an entire column, this would allow finer grained control.

Hi pat and tony,

I met the same problem, and modified the source of grid.celledit.js the following way to meet those requirements.

Here my modifications, at line 72 and following. The principe is just adding a var to receive the value and being able to test it.

Greetings,

zupert

Code :


var followEdit = true;
if ($.isFunction($t.p.beforeEditCell)) {
	followEdit = $t.p.beforeEditCell($t.rows[iRow].id,nm,tmp,iRow,iCol);
}
if (followEdit !== false) {
	$(cc).html("").append(elc);
	window.setTimeout(function () { $(elc).focus();},0);
	$t.p.savedRow.push({id:iRow,ic:iCol,name:nm,v:tmp});
	$("input, select, textarea",cc).bind("keydown",function(e) { 
		if (e.keyCode === 27) {$($t).restoreCell(iRow,iCol);} //ESC
		if (e.keyCode === 13) {$($t).saveCell(iRow,iCol);}//Enter
		if (e.keyCode == 9)  {$($t).nextCell(iRow,iCol);} //Tab
		e.stopPropagation();
	});
	if ($.isFunction($t.p.afterEditCell)) {
		$t.p.afterEditCell($t.rows[iRow].id,nm,tmp,iRow,iCol);
	}
}

Hi, Zupert, Pat and Tony!!

I also wanted to prohibit the editing of individual cells rather than the column immediately.

If you have managed styles for each cell (such as in the post Custom Cell Class) this could be quite simple: just check for class â€œreadonlyâ€ in cell:
