I have this array of picture boxes that hold bitmaps representings stars. I made a textbox that resizes itself as i type text in it or delete it(representing the name of the star). I need the custom textbox control to dynamically dock beneath the star. Logically this wasn't hard except i run into trouble thats why i'm here. The textbox docks and centers itself x-wise but not y-wise. It behaves like it ignores completely the

Parent.Controls[myStarIndex].Height

bit in the following code, but it behaves perfectly regarding the x part of the point calulations, can somebody help?

edit: Link to another thread i'm using to get help: http://forums.microsoft.com/MSDN/Sh...SiteID=1&mode=1

Also more of the code that could cause this behaviour but wich i also doubt it does.

private void StarName_Resize(object sender, EventArgs e)
{

if (Parent != null)
{

Point point = new Point();
int myTextBoxIndex = Parent.Controls.GetChildIndex(this);
int myStarIndex = myTextBoxIndex - 1;

point.X = Parent.Controls[myStarIndex].Location.X + Parent.Controls[myStarIndex].Width / 2 - Width / 2;

point.Y = Parent.Controls[myStarIndex].Location.Y + Parent.Controls[myStarIndex].Height;

Location = point;

}
}

the indexes are like this:

1 4 7 10 ...these are the cusom Star controls(image boxes)

2 5 8 11 ...these are the custom StarName controls(textboxes)

3 6 9 12 ...some other control i docked above the Star control

no poblem here i debugged and saw these numbers are proper, also if they weren't the textbox controls wouldn't dock anywhere near the Star control.

# 1 Re: problems dynamically moving a control

You presumably don't realise that this:Parent.Controls[myStarIndex].Location.Yis the same as this:Parent.Controls[myStarIndex].Topand this:Parent.Controls[myStarIndex].Location.Y + Parent.Controls[myStarIndex].Heightis the same as this:Parent.Controls[myStarIndex].BottomNow, there's some real inefficiency going on there. For a start, you're going to the Parent's Controls collection four times and getting the same control every time. If it's the same control then just get it once.

Apart from all that, I strongly suggest that you create your own UserControl. It should contain the PictureBox, the TextBox and the other control, plus the logic to resize and reposition the TextBox in relation to the PictureBox. All you have to do then is add multiple instances of that UserControl to your form and Bob's your uncle. The form doesn't have to know anything about any of that logic and neither does the TextBox. It's really a butcher job that the TextBox's internal logic relies on some other control that may or may not be on its Parent control. The UserControl should manage a set of three related controls and then the form can mange the UserControls.

With ".Bottom" still doesn't work but it is more efficient thanks for that.
I need to do it like this and i'm explaining next why. Still not working. So not obvious why too...

I allready did a custom control containing all that in a TableLayoutPanel, but, i don't want that overlapping any other controls by mistake. For instance if the textbox happens to be the widest in that control then the TableLayoutPanel width has to be that wide, and as high as the textbox + picture box + someothercontrol over the picture box 20 px high. And doing message filtering for the TableLayoutPanel looks awfully messy, not to mention that i would do it for the first time and need time researching into it.
