Radgridview rowvalidating

This will trigger the Row Validating event and the desired logic will be executed. Every column contains textbox, except 2nd and 9th: there's a combobox in 2nd and image for drag'n'rop in the 9th.Currently the validation occurs on row and cell level.To get notified, you can use the following events exposed by the Rad Grid View control: It is important to know that each one of the validation events is fired only when the user is trying to commit new data in the Rad Grid View control.The validation events are meant to support the data validation of the user input.They occur when the new content entered by the user is about to be committed.It is a Flags Enumeration and can take the following values: The cell validation occurs when a Grid View Cell is edited and its new data is about to be committed. You can do the same thing per row, using the Row Validating event. Length Figure 4 shows the result from a failed validation.At this moment, a Cell Validating event is fired and since the new value is not committed yet to the underlying data object, here is the perfect place for applying a custom UI validation. The Row Validating event is very similar to the Cell Validating event. Once you have added such errors, you will have to explicitly clear them when needed.

Attach to the Cell Validating event, which is exposed by the Rad Grid View. Example 5 shows how to validate the Order NO and Total properties of the Order object. Rad Grid View also allows you to take advantage of the System. Public Property Order NO() As String Get Return Me.m_order No End Get Set(By Val value As String) Dim validation Context As New Validation Context(Me, Nothing, Nothing) validation Context. Validate Property(value, validation Context) Me.m_order No = value End Set End Property Once the UI and Data validation is passed (i.e., the Binding tried to update the value for the bound property), the Cell Validated event is raised. Here you can also add a custom logic like changing the visual state of the editor (through the e. For a general example on how to validate the data, you can check our Validation WPF Demos.I have a Telerik rad Grid View on a form which has cell and row validation implemented. The problem arises when I leave a row incomplete and then click on the Save button elsewhere on the form. The Row Validating code snippet below does not work, because once the focus moves away from the gridview to the Save button, the if (row ! When the pencil icon is clicked the Row Validating event must be fired. When clicking the "pencil" icon, the current row is not changed, thus the Row Validating is not fired.A suitable event to cover this case is the Cell Validating event which will be triggered when the "pencil" icon is clicked. When the pencil is clicked, save the grid's Current Row, set it to null and then set it back to the saved row.
