TableGrid in dynamic reports

rbuser

I am exploring the use of the TableGrid component (RB15, corporate
purchasing is working on an updated license) in reports where the
construction must be dynamic, to deal with user options. I have
observed that in a TableGrid with more than one row, when I place in a
cell a TppLabel, for example, and want it in the second row of the
grid, I must assign the Top parameter based on the position in the
band, not in the cell.

So in a label placed in row 0, I will assign:
ALabel.Top := 0.0;

But for row 1, I write:
ALabelTop := MyGrid.Rows[0].Height;

Is this correct, or have I missed something about how to use the
TableGrid dynamically? I have looked for demos with the TableGrid, but
have not found any.

Thanks,

Bill Meyer

Hi Bill,

You posted about creating grids dynamically on April 4 and I provided an
example. In that example I used the Label.Anchors to position the Label
within the Row like this:

lLabel := TppLabel.Create(self);
lLabel.Caption := Table1.FieldDefs[liIndex].Name;
lLabel.Parent := ppTableGrid1.Cells[1,liIndex];
lLabel.Anchors := [atLeft, atTop, atRight];

If you don't want to use Anchors, you can set the Label.Top like this:

lLabel := TppLabel.Create(self);
lLabel.Caption := Table1.FieldDefs[liIndex].Name;
lLabel.Parent := ppTableGrid1.Cells[1,liIndex];
lLabel.Anchors := [atLeft, atRight];
lLabel.Top := ppTableGrid1.Rows[1].Top + myOffset;

Nard,

Thanks, you're right, I did post, and you did give an example. What
was not clear to me then, and is still not clear is why when I place,
for example, a TppLabel in a cell -- in the designer this time -- it
snaps to the column edges, but seems not to be affected by the row
boundaries.

Thanks,

Hi Bill,

When a Label is added to a TableCell, the Label.Anchors default to [atLeft,
atRight]. If you then modify the Label.Anchors to include atTop, then the
the Label will also snap to the Top.
