Q:

How to StartEdit in EditingPlugin in grid?

I know row index and column name. But EditingPlugin need
startEdit( Ext.data.Model record, Ext.data.Model columnHeader )</code>.

How I can take it and give it back?

A:

For the record you can do
record = grid.getStore().getAt(recordIndex);

but for the column header, I dont' think you needed it since startedit requeres the column not its header. In the CellEditing plugin doc it says column header but it describes it as the column object.
columnHeader : Ext.data.Model
The Column object defining the column to be edited
Provide a more detailed example giving the available local variables and I will try to gieve a solution for the column also.
