If rectangle locations exceed draw rectangle within panel

Question

hi

 

if(x>1000 || y>1000)

 

if these two coordinates went out of panel, bring that into 1000 location and draw rectangle within panel. donot allow to exceed in any case. I did something like this but iam getting negative values how to avoid that. Draw rectangle within panel only, check for all 4coordinates.

 

HighPreference 

 

Assume  

XCoordinate=1100         this is default my Panelsize(h=1013,w=1556)

Ycoordinate==1100

width=500

height=500 

 

How this is drawn for if width and height exceed panelsize.

_displayobj.height = panel1.Height - _displayobj.yCoordinate - padding;

_displayobj.width = panel1.Width - _displayobj.xCoordinate - padding;

if(_displayobj.xCoordinate>1000 ||_displayobj.yCoordinate>1000 || _displayobj.height<0 ||_displayobj.width<0)

{

var a =(panel1.Location.X);

var b = panel1.Location.Y;

_displayobj.xCoordinate = a;

_displayobj.yCoordinate = b;

_displayobj.height = panel1.Height - 12 - padding;

_displayobj.width = panel1.Width - 274 - padding;

}

if (_displayobj.rectWidth > _displayobj.width || _displayobj.rectHeight > _displayobj.height)

{

_displayobj.rectHeight = Math.Min(_displayobj.rectHeight, _displayobj.height);

_displayobj.rectWidth = Math.Min(_displayobj.rectWidth, _displayobj.width);

string message = ("The given size and location are not fit to this area, so we are adjusting rectangle withine drawing area.If you want to draw press 'OK'");

string title = ("Please Confirm Your Action");

MessageBoxButtons buttons = MessageBoxButtons.OKCancel;

DialogResult result = MessageBox.Show(message, title, buttons);

if (result == DialogResult.OK)

{

Graphics g = panel1.CreateGraphics();

g.DrawRectangle(Pens.Black, _displayobj.xCoordinate, _displayobj.yCoordinate, _displayobj.rectWidth, _displayobj.rectHeight);

txtHeight.Text = Convert.ToString(_displayobj.rectHeight);

txtWidth.Text = Convert.ToString(_displayobj.rectWidth);

panel1.Invalidate();

}

else if (result == DialogResult.Cancel)

{

_displayobj._isValid = false;

return _displayobj._isValid;

}

}

 

i wrote this is for X,Y exceed panel.But showing error not able to draw

if(_displayobj.xCoordinate>1000 ||_displayobj.yCoordinate>1000) 

 var c = 1000;

var d = 1000;

int newx, newy;

_displayobj.xCoordinate = c;

 _displayobj.yCoordinate = d;

 newx = _displayobj.xCoordinate - _displayobj.rectWidth - padding;

 newy = _displayobj.yCoordinate - _displayobj.rectHeight - padding;

 

help me how to solve this.please.

Thank u
