#Dbgrid component delphi how to

There is a nice article on on how to do this here. let's say we'll build one in the near future.I'd like to add DBLookupComboboxes to certain columns in a DBGrid. you'll be even more happy with a 'real' db-aware TDateTimePicker.

If you need any help, after you download and explore the full source code for this project, I encourage you to post any questions on the Delphi Programming Forum. Note: TDateTimePicker formats date and time values according to the date and time settings in the Regional Settings of the Control panel on the user's system - this is why you see Croatian date-time formatting. one nicely looking drop down calendar enabling you to change the value of DateAdded field's column. Procedure TForm1.DateTimePickerDropDown(Sender: TObject) If in thenДЄDOTable1DateAdded.Value := DateTimePicker.DateTime Procedure TForm1.DateTimePickerChange(Sender: TObject) Just handle the OnDropDown and the OnChange events: Just two more events to handle! What we need to do is to place the dataset into edit mode when the user opens the drop-down calendar, and we have to assign the value of the date that is marked on the calendar to the DateAdded field. SendMessage(DateTimePicker.Handle, WM_Char, word(Key), 0) We are primarily interested in the key - should move the input focus to the next cell. Next, note that when in editing mode, all keystrokes are going to the DBGrid's cell, we have to make sure they are sent to the DateTimePicker. Procedure TForm1.DBGrid1ColExit(Sender: TObject) Next, when we leave the cell, we have to hide the date time picker: We've already talked theory - I'll show you only the code here (you'll have the option to download the entire project later):ДЇirst, we need to make sure the DateTimePicker is moved (and sized) over the cell in which the DateAdded field is displayed. What's left for us to do, is to actually make a drop down calendar hover over a cell (when in edit mode) displaying the DateAdded field's value. As stated above, the TDateTime picker is not db-aware so there are no DB related properties to set. Using the Object Inspector, change the name of the TDateTime component to 'DateTimePicker'. Naturally, we first need to place a TDateTimePicker on a form, so drop one. Now, since we've already discussed the theory of adding controls to a DBGrid, I'll just list the necessary steps here, along with the code. Note that if you use the Fields editor at design time to create a persistent field component for the date-time field, you can access it by name at runtime - in our case the field is called 'DateAdded', and the TDateTimeField variable is 'AdoTable1DateAdded'. Once you set up a DBGrid displaying records from the Authors table, Delphi will add a TDateTimeField field object that represents the DateAdded field in the database table. Our sample MS Access database, quickiescontest.mdb, has a table named 'Articles' and this table has one date/time field called 'DateAdded'. Note: be sure to check this link in order to see what we are 'dealing' with. Let's start by creating a sample application. Since Delphi does not provide a DB-aware version of the TDateTimePicker component, we'll need to use some tricks to make our date picker appear inside a DBGrid - in this article you'll see the fastest way of implementing an 'in-dbgrid' drop down date (time) calendar picker.

The TDateTimePicker (on 'Win32' component palette tab) is a visual component designed specifically for entering dates or times. Of course, Delphi has all you need, just take the pieces (components and code) and of you go. Why not! If you have a database table containing a date (time) field you could/should be tempted to provide a calendar-like drop down selection for a user to select the date time value. If you are unfamiliar with the idea, please first read the 'Adding components to a DBGrid' article. The idea is to show how to place just about any Delphi control (visual component) into a cell of a DGBrid.

This is the fourth article, in the series of articles named 'Adding components to a DBGrid'. Yes! More controls are being added to a DBGrid! What a great idea! Let's see how to create the best data editing grid ever! Create visually more attractive user interfaces for editing date/time fields inside a DBGrid - place a drop down calendar into a cell of a DBGrid. Here's how to place a TDateTimePicker into a DBGrid.
