Hello Gayathri,

I am just checking if you got this worked out or you still require any assistance or clarification on the matter.

Thank you for checking Stephan, Actually the phone number is binded with a property called phonenumber. After the value changed event, it goes to a onpropertychanged event and assigns the same value again. This is a code written by someone and I am debugging it. So still looking for some work arounds in the present code.

Let me know if you have any ideas.

Hello Gayathri,

I am just checking the progress of this issue and was wondering if you managed to achieve your goal or if you need any further assistance on the matter.

Hi,

Thanks for checking. I moved on to other defects, I still have this issue.

Following are code related to this.

In xaml

<ig:TemplateColumn Key="PhoneNumber" HeaderText="Phone Number" Width="*">
                    <ig:TemplateColumn.ItemTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding PhoneNumber}" />
                        </DataTemplate>
                    </ig:TemplateColumn.ItemTemplate>
                    <ig:TemplateColumn.EditorTemplate>
                        <DataTemplate>
                            <ig:XamMaskedEditor Mask="999-999-9999CCCCCCCC" Value="{Binding PhoneNumber, Mode=Twoway}" ValueChanged="XamMaskEditor_ValueChanged" AcceptsReturn="True">
                                
                            </ig:XamMaskedEditor>
                        </DataTemplate>
                    </ig:TemplateColumn.EditorTemplate>
                </ig:TemplateColumn>                
            </ig:XamGrid.Columns>

Code behind:

  private void XamMaskEditor_ValueChanged(object sender, RoutedEventArgs e)
        {
            Infragistics.Controls.Editors.XamMaskedEditor xamEditor = (Infragistics.Controls.Editors.XamMaskedEditor)sender;
            if (xamEditor.Text == "___-___-____________")
            {
                xamEditor.ErrorMessage = "Phone Number is not in proper format.";
            }
        }

Viewmodel:

 [DataMember]
        public string PhoneNumber
        {
            get { return _phoneNumber; }
            set
            {
                if (_phoneNumber != value)
                {                  
                        _phoneNumber = value;
                        OnPropertyChanged("PhoneNumber");                   
                }
            }
        }
        private string _phoneNumber;

Thank you for the reply. Below is my usercontrol page structure.

I get nullreference again.

Hi Krasimir, Thanks for the reply. I get a NullReferenceException on XamMaskedEditor. Following is my code.

private void XamGrid_CellExitingEditMode(object sender, Infragistics.Controls.Grids.ExitEditingCellEventArgs e)

{

CompanyPhoneNumbers newPhoneNumber = (CompanyPhoneNumbers)e.Cell.Row.Data;

if (newPhoneNumber.PhoneNumber == "--")

{

Grid grid = e.Editor as Grid;

//XamMaskedEditor input= e.Editor as XamMaskedEditor -- this is also throwing nullreference.

XamMaskedEditor input = grid.Children[0] as XamMaskedEditor;

input.ErrorMessage = "Please enter a valid phone Number";

input.Focus();

return;

}

}
