Generated Image Tooltip

[Marek]

Hi, it's possible to create GridView Row toolTip with Image whose ImageSource is generated from Row data?

In my application I've collection of objects in GridView. Objects contains a few properties for generate image. I want to show tooltip with image generated from row when mouse is over it.

Hello Marek,

In order to achieve the desired result, you can handle RadGridView's RowLoaded event and set the tooltip of the current row there, possibly by using the DataElement property of the RowLoadedEventArgs:

public MainWindow()
{
    InitializeComponent();
    this.clubsGrid.RowLoaded += ClubsGrid_RowLoaded;
}

private void ClubsGrid_RowLoaded(object sender, Telerik.Windows.Controls.GridView.RowLoadedEventArgs e)
{
    var item = e.DataElement;
    BitmapImage tooltipImage = new BitmapImage();
    tooltipImage.BeginInit();
    tooltipImage.BaseUri = App.Current.StartupUri;
    tooltipImage.UriSource = new Uri("imageSource", UriKind.RelativeOrAbsolute);
    tooltipImage.EndInit();
    e.Row.ToolTip = new System.Windows.Controls.Image() { Source = tooltipImage };
}

Please let me know if this works for you.
