Topic: Editable TG

Happy New Year to all..........


I have this simple testing utility using treeview and editable tablegrid but couldn't get it working.
- cannot save and display tg records under selected treview node.


Here is the sample app:

Re: Editable TG

Hi


Delete 'bSearch' on increment search properties in the TableGrid1.
This makes it difficult to work out a double click to edit the cell.


In addition, you do not have a binding in the 'id_ItemsTree' field in the 'items' table.
If the tree entry contains no entry ( dbItemId = -1) then editing the entry in tg creates
an entry without a tree id. If the tree entry contains a value, then it can be edited.

Re: Editable TG

I did not write that I have a ready-made solution.
I just described why.
I'll try.
Of the options, do everything manually (reading, writing) or editing in a table and the first entry through a separate form.
This is what comes to mind immediately.
Really it is so critical, editing in the table?

Re: Editable TG

Thanks sparrow....
Having read, write, edit and delete functions on same form are much more useful for intended use.
Hopefully, there'll be solution...

Re: Editable TG

You can try like this.
There is a side effect, the last column in TG.
Unfortunately the column must be visible. But it may not be active.
Maybe someone can suggest a better solution.

Hi sparrow,
Thank you very much for your kind help...
Truly appreciated..........


I have added following lines to avoid out of index error when clicked on empty tg without selected treeview item with record:

procedure Form1_OnShow (Sender: TObject; Action: string);
begin
Form1.TreeView1.SelectedRow:= 0;
Form1.bSearch.Click;
Form1.TreeView1.SetFocus;
end;
