DBGrid How can I set Rows in read-only depending on a column value ?

[benoitclaeys]

Hello,

Want to allow edition of somes rows in a uniDBGrid, other ones must stay in read only. (for a Column, it' easy)

The Read only condition on a row must be driven by one column value of the row.

it's certainly done be aborting edition mode in a ExtJS event with a test on a value in a column... but I do not see how...

You can use beforeedit event of grid.

here is 2 example for second column.

 

with UniDBGrid1, JSInterface do
  begin
    JSAddListener('beforeedit', JSFunction('editor, e',' if (e.colIdx === 1){return false;}  return true; '));
  end;

  with UniDBGrid1, JSInterface do
  begin
    JSAddListener('beforeedit', JSFunction('editor, e',' if (e.record.get("1") === "Lee"){return false;}  return true; '));
  end;

Hi,

  If current column 'field a' position is 2 then we can use e.record.get("1");

but if move column 'field a' position to other (like 4 or 5 or etc.) then we how to get it?
