Can I Use a Checkbox in TWebDBGrid

WEB TMS WEB Core
1

It will only be local not conected to any Database field
I will only use it to copy selected records from on tabel to an other
but that part I know how to do
So just how to show a checkbox

2

For a cell in a column not connected to a DataField, call grid.AddCheckBox(col,row)

3

I have tried that but no checkbox shows
PROCEDURE TForm1.WebFormCreate(Sender: TObject);
BEGIN
some code......
WebDBGrid_Indian.AddCheckBox(0,0,TRUE);
WebDBGrid_Indian.AddCheckBox(0,1,FALSE);
END;

4

Try calling this after the dataset is activated

5

ok now I see them but when turning some of them on or off they all disapear

6

Please provide more details. Turning on / off , is that by clicking? via code? other?

7

yes by clicking

We've investigated this and have seen an issue when rows are updated from the dataset for columns that are not bound to a datafield.
We'll check what we can do about this.
For now, try to add a calculated boolean field to the dataset and use this to handle the checkbox for each row in the DB grid.

OK i will do that
How can I se if a checkbox is checked without saving it to the database

10

Did you try

grid.CheckState[col,row]: boolean;

11

it is not in the DB grid only in the stringgrid
but If I check one I can see if its checked by calling ... fieldbyname( a field).AsInteger = 1
and it was true if it was checked. And I never saved it to the database and it vas not saved after either.

We've seen an issue with the code editor LSP but you can write

var
  res: boolean;
begin
  res := webdbgrid1.CheckState [1,1];
end;

it will compile, it is effectively in the framework.

We'll look to fix the LSP issue.
