The Data Grid View class provides a convenient way to perform validation before data is committed to the data store.

You can validate data by handling the Cell Validating event, which is raised by the Data Grid View when the current cell changes.

This, therefore, undoes any action you perform in the handler.

What you have to do instead is change the value in the editing control (remembering not to cancel the event).

Hi there, I have a question regarding datagridview, I add data to the datagridview in an interface and all the validation for the datagridview cell is in the datagridview cell validating event for the datagridview.

I display the data of the is datagridview in another interface and make the cells read-only. But the thing is when I click on a row that data was added previously and press the Add new row the cell validating event is triggered.

For a complete explanation of this code example, see Walkthrough: Validating Data in the Windows Forms Data Grid View Control.

Form Private With Events data Grid View1 As New Data Grid View() Private binding Source1 As New Binding Source() Public Sub New() ' Initialize the form.

Empty End Sub Private Shared Function Get Data(By Val select Command As String) As Data Table Dim connection String As String = _ "Integrated Security=SSPI; Persist Security Info=False;" _ "Initial Catalog=Northwind; Data Source=localhost; Packet Size=4096" ' Connect to the database and fill a data table. Also see How to: Compile and Run a Complete Windows Forms Code Example Using Visual Studio.

You can also build this example in Visual Studio by pasting the code into a new project.
