From Visual Studio, all you'd have to do is add the MDB file to the project and it will automatically launch the Data Source Conversion Wizard. You can perform most of these tweaks by either using the designer or via code. Padding = p ' set the monetary string format style.

At the conclusion of this wizard, you'll have a strongly-typed dataset, a Table Adapter, and Data Table added to your project. Products) End Sub ' ' Save the changes you've made via the Data Grid View back to the ' underlying database ' Private Sub bn Update_Click(By Val sender As System. Let's look at how you could perform some simple tweaks in a column that contains a Money field. Format = "$#.00" ' apply the style to the column Data Grid View1. Default Cell Style = style The major technique for detected errors in a Data Grid View is by the Row Validating event.

Let's see what's required to implement a custom column control.

The source code for the custom Data Grid View Masked Edit Column is found below.

This custom Data Grid View column control is contained in 3 classes...

A Column control that inherits from Data Grid View Column, a Cell control that inherits from Data Grid View Text Box Cell, and an Editing Control that implements the IData Grid View Editing Control interface The Masked Edit Column class is fairly straight forward; it only overrides one property (to ensure that the correct cell type it used).

Value Member = "Category ID" ' the numeric value to look up in the "child" table dgvc.

Display Member = "Category Name" ' the column value you want displayed dgvc. Get Data() ' the child table ' some more tweaking dgvc. Automatic ' insert the new column at the same location Data Grid View1. Insert(index, dgvc)) Now the user can select the user-friendly Category strings and also is prevented from selecting a value that's not a valid Category ID If the 5 built-in column types is not sufficient, it is fairly easy to add a custom column type yourself.

The Data Grid View is a very powerful windows form control for providing a user interface to tabular data.

It has the initial "look and feel" of an Excel spreadsheet.

It also implements the properties that will be required later on by the Masked Text Box control, namely the Mask, Prompt Char, and Validating Type properties.

Public Class Data Grid View Masked Edit Column Inherits Data Grid View Column Private p Prompt Char As Char = "_"c Private p Validating Type As Type = Get Type(String) Private p Mask As String = "" Public Sub New() My Base. Prompt Char End Sub Public Overrides Read Only Property Edit Type() As Type Get ' Return the type of the editing control that Masked Edit Editing Control uses.

Next, you'll need to add a Data Grid View to a form. ' create new style object Dim style As New Data Grid View Cell Style ' set the alignment to the right (for numbers) style. Middle Right ' add a wee bit of padding to the right side Dim p As New Windows. This allows you to use a "business rule" to validate the user input.
