One of the most important features provided by Rad Grid View is the data validation.

Data validation features enable you to take complete control of the data entered in your grid's cells. This is the validation that is built into the business object implementation.

Add(New Course With ) End Sub End Class Public Class Course Implements IEditable Object, INotify Property Changed Private _name As String Public Property Name As String Get Return _name End Get Set(By Val value As String) If _name = value Then Return _name = value On Property Changed("Name") End Set End Property Private _number As Integer Public Property Id As Integer Get Return _number End Get Set(By Val value As Integer) If _number = value Then Return _number = value On Property Changed("Id") End Set End Property Private _start Date As Date Time Public Property Start Date As Date Time Get Return _start Date End Get Set(By Val value As Date Time) If _start Date = value Then Return _start Date = value On Property Changed("Start Date") End Set End Property Private _end Date As Date Time Public Property End Date As Date Time Get Return _end Date End Get Set(By Val value As Date Time) If _end Date = value Then Return _end Date = value On Property Changed("End Date") End Set End Property #Region "IEditable Object" Private backup Copy As Course Private in Edit As Boolean Public Sub Begin Edit() Implements IEditable Object.

Culture Info) _ As Validation Result Dim course As Course = _ CType(CType(value, Binding Group).

It may be set to one of the following values: In R2 2016, Telerik introduced the Validation Type property of Rad Grid View. This results in a binding validation error (Figure 3) and the Grid View Bound Column Base editor will enter into an invalid state.

It provides you with the possibility to choose what type of validation to apply for each instance of Rad Grid View. In the previous examples, the data was validated per cell, using the Cell Validating event or property validation.

dgd Eligible Files contains a list of files & file info, and a checkbox column - if a row is checked, the file it represents is "assigned" to the selected row in dgd Applications (a row/application in dgd Applications may have many files assigned to it). If "Yes", I want to proceed with dgd Applications_Mouse Click on the new row, which will do the following: clear the checkboxes in dgd Eligible Files, retrieve the list of files for the newly selected app in dgd Applications, and update checked/selected values in the underlying list bound to dgd Eligible Files (followed by dgd Eligible Files. My problem: When the messagebox is displayed in dgd Applications.

If a user has altered his assignments in dgd Eligible Files (checked/unchecked one/more rows) without clicking the Save button at form-bottom, and then clicks another row in dgd Applications, I currently use dgd Applications_Row Validating to pop a messagebox and verify that the user wants to proceed to the newly-selected application/row without saving changes. Row Validating and the user chooses "Yes" to continue (abandoning changes in dgd Eligible Files and going to the new row in dgd Applications), dgd Applications_Mouse Click does not get executed and nothing changes in dgd Eligble Files. When I put break points in both the Row Validating and Mouse Click event handlers, I never see Mouse Click execute - I only see Row Validating.

With row-level validation, you validate entire data objects when a user commits changes to a row. Component Model Public Class Main Window Private Sub data Grid1_Initializing New Item(By Val sender As System.

You can also provide customized visual feedback for validation errors, or use the default visual feedback that the Data Grid control provides.

So, here you go: Example: Client-Side Validation In this sample, we use the Grid View Edit Form Template Container.
