Hi @g-tech,
Thank you for the report. We will investigate.

Created an Issue.
https://github.com/extnet/Ext.NET/issues/354
Please try the following fix.
Fix
Code:Ext.grid.plugin.CellEditing.override({
showEditor: function(ed, context, value) {
var me = this,
record = context.record,
columnHeader = context.column,
sm = me.grid.getSelectionModel(),
selection = sm.getCurrentPosition(me.grid.view),
otherView = selection && selection.view;
// Selection is for another view.
// This can happen in a lockable grid where there are two grids, each with a separate Editing plugin
if (otherView && otherView !== me.view) {
return me.lockingPartner.showEditor(ed, me.lockingPartner.getEditingContext(selection.record, selection.columnHeader), value);
}
me.setEditingContext(context);
me.setActiveEditor(ed);
me.setActiveRecord(record);
me.setActiveColumn(columnHeader);
// Select cell on edit only if it's not the currently selected cell
if (sm.selectByPosition && (!selection || selection.column !== context.colIdx || selection.row !== context.rowIdx)) {
if (!sm.isCellModel && sm.select) {
sm.select(record);
}
else {
sm.selectByPosition({
row: context.rowIdx,
column: context.colIdx,
view: me.view
});
}
}
ed.startEdit(me.getCell(record, columnHeader), value, context);
me.editing = true;
me.scroll = me.view.el.getScroll();
}
});
Ext.selection.RowModel.override({
getCurrentPosition: function(view) {
var firstSelection = this.selected.items[0];
if (firstSelection) {
return new Ext.grid.CellContext(view || this.view).setPosition(this.store.indexOf(firstSelection), 0);
}
}
});
It has been fixed in the revision #5729. It goes to the v2.5.1 release.
This case is apparently no longer actual as of Ext.NET 4. There's no longer a showEditor override to CellEditing and tests with grids with locking columns worked fine.
