TLMDDBGrid / LMDGridFloatColumn issues

RCScoringPro

Bug? I have a TLMDDBGrid, with 3 columns.  I want to add a integer
column, there is no button for this.  The only way I can see to add it
is to add all columns, and it's added automatically.

My question
is how do I force a float value to display 3 decimals?  I set the
'FloatFormat' value to   #.000    this did not work

Also, I just
want to display the data in the grid, I don't want it to appear like any
row is selected.  The first field in the first row has a thicker black
border around it, how do I get rid of that?

Thanks!

Hi,

There is a line of buttons with different column types at the top of the grid's column editor.

Hi,

About FloatFormat: In Db version of the grid this property is linked with the corresponding TField.EditFormat property. For better understanding you can review the following code (which is a part of LMDGrid package):

procedure TLMDGridFloatColumn.CheckInitPropsForField;

var

  field: TField;

  ff:    TFloatField;

begin

  Assert(Grid <> nil);

  field := Grid.GetColumnField(Self);

  if (field <> nil) and (field is TFloatField) then

  begin

    ff := TFloatField(field);

    Precision := ff.Precision;

    IsCurrencyMode := ff.Currency;

    FloatFormat := ff.EditFormat;

  end;

end;

Here I can't understand what you speak about...

Issue #1

In the attached picture, the field that has the title "Lap Time" I want to have 3 digits for the decimal.  The 'difference' field is what is being displayed as "Lap Time".  I have the "DisplayFormat" as #.000

As you can see, 50.71 is displayed in the grid, it should be 50.710

Issue #2

Each TLMDGrid has the selected row displayed with white text on a black background. This appears to be random as to which line will be selected when I create the frame.  I'd rather have it just be black text on white like the row isn't selected.  I think I saw those colors somewhere in the properties.  My issue is the dots around the selected field.  So in the picture I have the "11" circled in red. I don't want to dotted lines appearing around the cell.

Where can I find the header file containing the attributes to the TLMDGridColumn?  I want to custom draw my cells, can't find where the TLMDGridColumn is defined.

Thanks for the help!

Hi,

1) I said EditFormat, not DisplayFormat.

2) You should exclude opDrawFocusSelected flag from Grid.Options.

TLMDGridColumn declaration resides in LMDGrid.pas file. If you are registered user, you can just download sources. If you speak about C++ hpp file, then it should be somewhere in your installation; otherwise it will be impossible to compile projects...

When you don't want to download the sources (as separate installer) - you can also search the interface files (in \interfaces folder of your instalaltion (when installing interfaces was checked in installation)).
