Hi Tim,

IMHO, the EWB2 documentation is very good, however, I feel it is a little lacking in how to use TGrid in unbound mode.  For example: adding rows; deleting rows; clearing the grid; adding values to, and reading values from, cells.

That's pretty important information from my perspective. I realise it's early days for EWB2 and not everything is in the doco yet.

While on the subject of the TGrid, is there any word on when there might be a column that can support images?

I couldn't see anything in the EWB2 Roadmap.  I use grids a lot in my applications, and I use images as status indicators, etc.

Thanks.

I'm trying to squeeze it into the 2.01 release, but it depends upon how fast
I can finish up the rest of the un-bound grid features, which are taking
precedence right now.

Thanks Tim/Demo User.  I'd be happy with just a quick list of the methods in a forum post in the interim.

Same here.

I have spent the past 2 hours trying to figure out stuff that really should be a quick click away for the info.

Still no closer to knowing how to add data to the Cells.

This is how I am adding data in a loop:

    grdUsers.AppendRow;
    grdUsers.Rows[i][FIRSTNAME_COLUMN] := Firstname;
    grdUsers.Rows[i][LASTNAME_COLUMN] := Lastname;
    grdUsers.Rows[i][EMAIL_COLUMN] := Email;
    grdUsers.Rows[i][ACTIVE_COLUMN] := Active;
    grdUsers.Rows[i][LAST_LOGIN_COLUMN] := LastLogin;
    grdUsers.Rows[i][USER_ID_COLUMN] := UserID;
    grdUsers.Rows[i][PASSWORD_COLUMN] := Password;

And this is how I am reading the values of a selected row:

    UserID := grdUsers.Rows[grdUsers.RowIndex][USER_ID_COLUMN];
    Firstname := grdUsers.Rows[grdUsers.RowIndex][FIRSTNAME_COLUMN];
    Lastname := grdUsers.Rows[grdUsers.RowIndex][LASTNAME_COLUMN];
    Email := grdUsers.Rows[grdUsers.RowIndex][EMAIL_COLUMN];
    Password := grdUsers.Rows[grdUsers.RowIndex][PASSWORD_COLUMN];
    Active := grdUsers.Rows[grdUsers.RowIndex][ACTIVE_COLUMN];
    LastLogin := grdUsers.Rows[grdUsers.RowIndex][LAST_LOGIN_COLUMN];

BTW, I always use constants for column indexes so I don't have to remember the column numbers, and they can easily be changed in one place if I decide to reorder the columns:

const
  FIRSTNAME_COLUMN                    = 0;
  LASTNAME_COLUMN                     = 1;
  EMAIL_COLUMN                        = 2;
  ACTIVE_COLUMN                       = 3;
  LAST_LOGIN_COLUMN                   = 4;
  USER_ID_COLUMN                      = 5;
  PASSWORD_COLUMN                     = 6;

So the format is: grdUsers.[RowNo][ColumnNo]

Steve,
Thank you! Absolutely timely assistance!

I just replaced the grid with a ListBox and looking for a workaround.

<< So the format is: grdUsers.[RowNo][ColumnNo] >>

That simply bit of information goes a long way!

Yes. Constants are indeed is much easier and I shall use accordingly.

Thanks again.

<< So the format is: grdUsers.[RowNo][ColumnNo] >>

Sorry, that should be grdUsers.Rows[RowNo][ColumnNo]

<< Sorry, that should be grdUsers.Rows[RowNo][ColumnNo] >>

Oops, yes you're right. Sorry that was a typo.

Thanks for the info in this thread, it made all the difference to my
sanity.
I even managed to select a cell with:
  AGrid.RowIndex := ARow;
  AGrid.ColumnIndex := AColumn;
Not sure if that is the correct way, but it does for now.

Yes, that is the correct way of doing it.

There is documentation on all of this in the component reference that explains what the methods and properties do:

http://www.elevatesoft.com/manual?action=viewcomp&id=ewb2&comp=TGridControl

(one or more of those properties/methods are from 2.01, and may not be documented yet)
