Getting header width during HDN_ENDTRACK

mfc >> Getting header width during HDN_ENDTRACK

How would I go about getting total width of a CHeaderCtrl within code that
is run in response to HDN_ENDTRACK?
Right now I sum widths of all header item rects to get the total width, but
it seems that at the time HDN_ENDTRACK is handled GetItemRect() returns the
previous column rectangles (before the change) - not the new ones.
I need to do this in HDN_ENDTRACK to update scrollbars properly in response
to header column width changes.

If a scrollbar appeared on the right side of the panel control, How can
I get the real content width?

4. .Net 2.0 GridView Header fixed width problem

Hi,

In the C#.Net 2.0 webform, I have a GridView GV1.
The question is the width of the GV1's header is not fixed, sometimes if the
item is long,
then the header of that item just shrinks.
How do I fix this problem?
Thanks for help.

8. WPF: Getting correct Width of Control with Adorner

Hi,
I wanted to create a textbox with an depending Label so that I do not have 
to add a label each time I add TextBox to a window and tried the following:

    public class LabelTextBox : TextBox
    {
        public static readonly DependencyProperty LabelPositionProperty = 
DependencyProperty.Register("LabelPosition", typeof(enAdornerPosition), 
typeof(LabelTextBox), new FrameworkPropertyMetadata(enAdornerPosition.Left, 
new PropertyChangedCallback(OnLabelPropertyChanged)));
        public static readonly DependencyProperty LabelCaptionProperty = 
DependencyProperty.Register("LabelCaption", typeof(string), 
typeof(LabelTextBox), new FrameworkPropertyMetadata("LabelTextBox", new 
PropertyChangedCallback(OnLabelPropertyChanged)));
        public static readonly DependencyProperty LabelWidthProperty = 
DependencyProperty.Register("LabelWidth", typeof(double), 
typeof(LabelTextBox), new FrameworkPropertyMetadata((double)90, new 
PropertyChangedCallback(OnLabelPropertyChanged)));

        public LabelTextBox()
        { }
        
        public double LabelWidth
        {
            get { return (double)GetValue(LabelWidthProperty); }
            set { SetValue(LabelWidthProperty, value); }
        }

        public string LabelCaption
        {
            get { return (string)GetValue(LabelCaptionProperty); }
            set { SetValue(LabelCaptionProperty, value); }
        }

        public enAdornerPosition LabelPosition
        {
            get {return (enAdornerPosition)GetValue(LabelPositionProperty); }
            set {SetValue(LabelPositionProperty, value);}
        }
        
                static void OnLabelPropertyChanged(DependencyObject d, 
DependencyPropertyChangedEventArgs e)
        {
            LabelTextBox soBox = (LabelTextBox)d;
            AdornerLayer soAdornerLayer = AdornerLayer.GetAdornerLayer(soBox);
            if (soAdornerLayer != null)
            {
                try { foreach (Adorner soAdorner in 
soAdornerLayer.GetAdorners(soBox)) { soAdornerLayer.Remove(soAdorner); } } 
catch { }
                double sdWidth = soBox.LabelWidth;
                TextBlock soLabel = new TextBlock() { Text = 
soBox.LabelCaption, Width = sdWidth, Foreground = soBox.Foreground };
                GenericAdorner soAdoner = new GenericAdorner(soBox, soLabel, 
soBox.LabelPosition, sdWidth);
                soAdornerLayer.Add(soAdoner);
            }
        }
    }

This still works fine besides the effect that the adorner is not included in 
the control width and resizing the control / window is still an adventure 
wharf the GUI will look like afterwards.

Is there a way to correct the control width (i tried something like an new 
Width Property which returns Textbox.Width+Label.Width, but this did not 
work...)?

Does anybody know how to do this?

Thanx,
Chris
