Title: How to set Directory-Select in Editfields
Question: In an DBGrid-Column the user must fill in any Pathname.
Give him the chance to do this with an Selectionmenu!
Answer:
This is an very easy job.
Your Table must have a Alpha-Field to store the selected pathname.
First you must set the Buttonstyle-Property of this DBGrid-Column to cbsEllipsis (Doubleclick on DBGrid - select the Column-name - set the Buttonstyle).
Second you must create an DBGrid-Edit-Button-Click-Routine to start this Selectionmenu.
Every Time the user clicks in this Column the Selectionmenu starts and the selected pathname is returned in the Variable SelDir. Now you can change and store this value in the Tablefield.
Thats it.
uses FileCtrl;
procedure TForm1.DBGrid1EditButtonClick(Sender: TObject);
var
SelDir: string;
begin
SelDir := 'C:\'; // Default Start and Returnvalue
if SelectDirectory(SelDir, [sdAllowCreate, sdPerformCreate, sdPrompt], 1000) then begin
Table1[''] := SelDir + '\*.*';
Table1.post;
end;
end;
