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.
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.
From inside the Form Designer, you should see a very small triangle at the upper right-hand corner of the Data Grid View control. For example, if the Units On Hand column can never be a negative number,you could write a validating rule that looks to see if the value is negative prior to committing the changes to that row.
Click on this triangle to select the data source that was created for you when you ran the Data Source Conversion Wizard. You can use the Error Provider class to display the problems detected during validation.

Let's say that you have a Microsoft Access database that you plan to use in your program. For example, all columns are aligned to the left and have have no formatting.
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.
