[Solved] CurrentItem

[Jennifer]

How do I get the current row I am on in the grid. I have a grid with a MODIFY and DELETE button in each row and I need to know which row they are on when they click the button. Or should I being doing this differently. I want to have them MODIFy in an another window instead of in the grid.

I tried using this binding but its always "0".
CurrentItem="{Binding TemplatesGridIndex, Mode=TwoWay}"

Thanks

Here is my grid XAML code

<telerikGridView:RadGridView x:Name="radGridViewTemplates"  
                         AutoGenerateColumns="False"  IsFilteringAllowed="False"  ShowGroupPanel="False"   
                        ItemsSource="{Binding MyTemplates}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
                        CurrentItem="{Binding TemplatesGridIndex, Mode=TwoWay}"  >
                        <telerikGridView:RadGridView.Columns>
                            <telerikGridView:GridViewColumn>
                                
                                <telerikGridView:GridViewColumn.CellTemplate>
                                    <DataTemplate>
                                        <Button x:Name="btnModify" Content="Edit" Click="btnModify_Click"  />
                                    </DataTemplate>
                                </telerikGridView:GridViewColumn.CellTemplate>
                            </telerikGridView:GridViewColumn>
                            
                            <telerikGridView:GridViewColumn>
                                <telerikGridView:GridViewColumn.CellTemplate>
                                    <DataTemplate>
                                        <Button x:Name="btnDelete" Content="Delete" />
                                    </DataTemplate>
                                </telerikGridView:GridViewColumn.CellTemplate>
                            </telerikGridView:GridViewColumn>
                            <telerikGridView:GridViewColumn>
                                <telerikGridView:GridViewColumn.CellTemplate>
                                    <DataTemplate>
                                        <Image Source="{Binding Path=ImageURL, Converter={StaticResource ImageConverter}}"  Height="50" Width="100" Stretch="UniformToFill"  />
                                    </DataTemplate>
                                </telerikGridView:GridViewColumn.CellTemplate>
                            </telerikGridView:GridViewColumn>
                            <telerikGridView:GridViewDataColumn
                                HeaderText="Title" HeaderTextAlignment="Left" DataMemberBinding="{Binding Title}" />
                            <telerikGridView:GridViewDataColumn
                                HeaderText="Description" HeaderTextAlignment="Left" DataMemberBinding="{Binding Description}"/>
                        </telerikGridView:RadGridView.Columns>
                    </telerikGridView:RadGridView>

Hello Jennifer,

You could use our ParentOfType extension method to get the parent row when you click on a button:

// required namespace: using Telerik.Windows.Controls;
private void Button_Click_1(object sender, RoutedEventArgs e)
{
    var senderElement = sender as FrameworkElement;
    var parentRow = senderElement.ParentOfType<GridViewRow>();
    var parentDataItem = parentRow.DataItem;
}

All the best,

when i pasted above code,

For "GridViewRow" it shows Type or Namespace name is not found...

I can see "GridViewColumn" but not "GridViewRow" in variable list.

Thanks

Hello Virendra,

You can use the Visual Studio IntelliSence to add needed namespace - this this case Telerik.Windows.Controls.GridView.

Beautiful.  It worked. Thanks

I am a little confused with knowing the current row of a grid.

I am looking at a college's code who used the datagrid that comes with Visual Studio Silverlight. He has this in his XAML:

 <data:DataGrid x:Name="dgConfigSettings" Grid.Row="2" AutoGenerateColumns="False" ItemsSource="{Binding KioskConfigSettingsDataSource}" SelectedIndex="{Binding ConfigSettingsDGIndex, Mode=TwoWay}">
                              
Then he has a DELETE button in one of his columns.  When that is clicked, the row index is contained in
"ConfigSettingsDGIndex".

Then he can just use this to remove the current row from the grid:
         KioskConfigSettingsDataSource.RemoveAt(ConfigSettingsDGIndex);
where
        KioskConfigSettingsDataSource is an Observable Collection bound to grid

How can I do this with the Telerik grid?

Thanks

Now I am getting it. Thanks so much for your help. Worked perfectly.
Its been quite a learning curve for me even coming from an ASP.NET background.
And we are using the Prism libraries as well.
