GridViewComboBoxColumn on change to update two other columns

[Greg]

Hello,

I'm a noob to WPF. I inherited an MVVM WPF project using Caliburn.Micro.

I have this gridview:

<telerik:RadGridView Margin="10"
                                         CanUserFreezeColumns="False"
                                         MaxHeight="300"
                             RowIndicatorVisibility="Collapsed"
                             IsReadOnly="False"
                             ScrollMode="Deferred"
                             BeginningEdit="RadGridView_BeginningEdit"
                             CellEditEnded="RadGridView_CellEditEnded"
                             ScrollViewer.PanningMode="VerticalFirst"
                             ScrollViewer.HorizontalScrollBarVisibility="Visible"
                             ItemsSource="{Binding SelectedCollectionPatient.CollectionTests}"
                             SelectedItem="{Binding SelectedCollectionTest}"
                             AutoGenerateColumns="False"
                             IsFilteringAllowed="False"
                             ShowGroupPanel="False"
                                         >

                        <telerik:RadGridView.Columns>

                            <telerik:GridViewComboBoxColumn ItemsSource="{Binding Path=DataContext.SelectedCollectionPatient.CurrentStatusList,
                                                RelativeSource={RelativeSource FindAncestor,
                                                AncestorType={x:Type Window}}}"
                                                Width="145" IsReadOnly="False"
                                                DataMemberBinding="{Binding CurrentStatus}"
                                                Header="Collection Status"
                                                UniqueName="CurrentStatus" >
                            </telerik:GridViewComboBoxColumn>

                            <telerik:GridViewDataColumn Width="*" IsReadOnly="False"
                                            DataMemberBinding="{Binding CollectionTime, StringFormat='{}{0:hh:mm tt}' }">
                                <telerik:GridViewDataColumn.CellEditTemplate>
                                    <DataTemplate>
                                        <StackPanel Orientation="Horizontal">

                                            <telerik:RadMaskedDateTimeInput Margin="0"
                                                                     telerik:TouchManager.IsTouchHitTestVisible="False"
                                                                     EmptyContent="No Time Entered"
                                                                     VerticalContentAlignment="Center"
                                                                     Height="50" Width="150" Mask="hh:mm tt"
                                                                     Value="{Binding CollectionTime, UpdateSourceTrigger=PropertyChanged}">
                                            </telerik:RadMaskedDateTimeInput>

                                            <telerik:RadButton Command="{Binding RelativeSource={RelativeSource FindAncestor,
                                                            AncestorType={x:Type Window}},
                                                            Path=DataContext.SetCurrentTimeCommand}" Width="35" Margin="0">
                                                <Image Source="/HomeCollections.UI;component/Images/Icons/time.png" Width="16" Stretch="None"></Image>
                                            </telerik:RadButton>
                                        </StackPanel>
                                    </DataTemplate>
                                </telerik:GridViewDataColumn.CellEditTemplate>
                            </telerik:GridViewDataColumn>

                           <telerik:GridViewComboBoxColumn ItemsSource="{Binding SelectedCollectionPatient.ReasonList}"
                                                Width="165" IsReadOnly="False"
                                                DisplayMemberPath="ReasonText"
                                                SelectedValueMemberPath="UncollectedReasonId"
                                                DataMemberBinding="{Binding UncollectedReasonId}"
                                                Header="Uncollected Reason">
                            </telerik:GridViewComboBoxColumn>

                        </telerik:RadGridView.Columns>
                    </telerik:RadGridView>

When the CurrentStatus combo box column is changed, I want to check the status and:
1) update or clear the CollectionTime  (the masked input)
2) update or clear the UncollectedReason column

I'm current trying to do it in the RadGridView_CellEditEnded event... but haven't been able to figure it out.

if (e.Cell.Column.UniqueName == "CurrentStatus")
            {
                if (e.NewData != e.OldData)
                {
}
}

Thanks.

Hello,

You can check the Handle SelectionChanged for the GridViewComboBoxColumn article. Once the selection has changed, you can proceed further with your additional information.

Thanks. Got it working perfectly.

I had to to do some clever coding to figure out which combobox was firing. Not sure why uniquename is not there.

Can you please help me with the code as I am facing the same issue. Like I have radgridview and binded it using list and autogeneratedcolumns = false and I have one dropdown column and while changing I want to update another column with certain value. So the value updated in the Itemsource but Grid not updated and showing old value.

As the solution page not opening. Can you please help me on this.
