Hi,

i'm using controls library for SL3 (Product version 2010.1.0309.1030) and currently i want to achieve this kind of functionality in radGridView:

user selects row, and can see expanded row details, but selected row should be hidden. What and how i should define in xam'l to achieve this? Is this possible at all? I have ControlTemplate for my gridViewRow, and tried to do it like this:

<VisualState x:Name="Selected">
                            <Storyboard>
                                <ObjectAnimationUsingKeyFrames Storyboard.TargetName="DataCellsPresenter" Storyboard.TargetProperty="Visibility">
                                    <DiscreteObjectKeyFrame KeyTime="0:0:0" Value="Collapsed"/>
                                </ObjectAnimationUsingKeyFrames>
                            </Storyboard>
                        </VisualState>

but it hides just cells presenter, this means that i still can see the row just without cells.. can't find how can collapse entire row...


thanks

Hello Gintaras Vaitkus,

You may take a look at this forum thread. However, the project there is for Silverlight 4, so I am sending you the same one but for Silverlight 3.

One problem with atached sample.. when trying navigate from item to item using keyboard arrows (up and down) it doesn't work correctly, sometimes (randomly) some items are skipped, and i'm unable to jump to the last item with arrows somewhy.. can't figure out why it happens, i checked, there is no such problem in gridview sample with row details in controls library showcase... maybe it is because of this active row hiding? Do you have any ideas how to fix this weird behaviour?


thanks

Hello Gintaras Vaitkus,

Indeed some of the rows are skipped when using the Up and Down Keys and it turns out to be as a result of loss of the focus. What could be done in this case is to reset and predefine those two commands in a CustomKeyboardProvider class that implements DefaultKeyboardCommandProvider. For example key.down can be handled as follows:

if (e.Key == Key.Down)
            {
                int i = this.playersGrid.Items.Count;
 
                if (this.playersGrid.SelectedItem != null && (this.playersGrid.Items.IndexOf(this.playersGrid.SelectedItem) + 1) < i)
                {
                    this.playersGrid.SelectedItem = this.playersGrid.Items[this.playersGrid.Items.IndexOf(this.playersGrid.SelectedItem) + 1];
                }


I am sending you a sample project so that you can see and test the proposed solution.


Kind regards,
