Rowvalidating missing properties

[martin bertram]

Hi,

I am using a WPF radgridview and the RowValidating event:

 

 

Private Sub RadGridView1_RowValidating(ByVal sender As System.Object, ByVal e As Telerik.Windows.Controls.GridViewRowValidatingEventArgs)

 

e.IsValid =

 

False

 

 

 

End Sub

 

According to the documentation, there is a NewValues property which can be used to access the new values, as well as an OldValues property.  The OldValues property is there but I don't see NewValues.  Also, is there any way to provide an error message for rowvalidating like you can with cellvalidating?

Thanks

Hi martin bertram,

Indeed, you are quite right. We have made that property obsolete and removed it. However, we are considering the implementation of another - similar, but improved one that will replace the NewValues.
As for your second requirement, you may add GridViewCellValidationResult, set its ErrorMessage property and add it to the ValidationResults collection.

Kind regards,

Is there any way for me to retrieve the values of the cells in a row during the RowValidating event?

Hi martin bertram,

You may use exposed properties - in this case "Row" and get the corresponding item. Afterwards, you will be able to retrieve the values by its properties. For example:

private void clubsGrid_RowValidating(object sender, GridViewRowValidatingEventArgs e)
{
    var row = e.Row as GridViewRow;
    var club = this.clubsGrid.ItemContainerGenerator.ItemFromContainer(row) as Club;
    if(club != null)
    {
        var name = club.Name;
        var established = club.Established;
        var capacity = club.StadiumCapacity;
    }
}

Sincerely yours,
