I've added a picture type item to my property grid with an expand button to allow the user to select the desired image. Once the image is selected I see that a tiny preview image is shown on the grid item. Is there a built in method that I can use to allow the user to view a larger version of the preview or will I need to add my own inplace button and open the image in a separate window or picture control?

 

Thanks!

 

You have to calculate the width & height of the image yourself and use Item.PreviewWidth & Item.Height to set the desired size. 

 

If you would add the selected image to PropertyGridControl.Icons collection which knows the width & height already and use the GetImage method to get desired width & height and use these to size the PropertyGridItem... Something like this:

 

Private Sub wndPropertyGrid_ValueChanged(ByVal Item As XtremePropertyGrid.IPropertyGridItem)
    
    If Item.Type = PropertyItemPicture Then
        Me.wndPropertyGrid.Icons.RemoveIcon 999

 

        'Note: before adding image to .Icons you have to check if image is an Icon or a Bitmap
        Me.wndPropertyGrid.Icons.AddIcon Item.Value, 999, xtpImageNormal
       
        'Size PropertyGridItem

        Item.PreviewWidth = Me.wndPropertyGrid.Icons.GetImage(999, 0).Width
        Item.Height = Me.wndPropertyGrid.Icons.GetImage(999, 0).Height
    End If

End Sub

 

 

Hope this helps a little
