WinForm Adaptive screen resolution specific operation and precautions

First step: First with the help of a class file AutoSizeFormClass.cs

Class Autosizeformclass
{
public struct Controlrect
{
public int left;
public int Top;
public int Width;
public int Height;
}
(2). Declaring 1 objects
Note that you cannot use the control list to record list Nctrl; Because of the control's associativity, the record is always the current size.
Public list oldctrl= new list ()///here will be the Latin greater than less than the filter out, can only be changed to Chinese, use to change back to Latin
Public list<controlrect> Oldctrl = new list<controlrect> ();
int ctrlno = 0;//1;
(3). Create two functions
(3.1) record the initial position and size of the form and its controls,
public void Controllinitializesize (Control mform)
{
Controlrect CR;
Cr.left = Mform.left; Cr.top = Mform.top; Cr.width = Mform.width; Cr.height = Mform.height;
Oldctrl.add (CR);//The first one is "form itself", only one time
AddControl (mform);//The remaining controls in the window may also nest controls (such as a panel) and be extracted separately, as they are called recursively
This. WindowState = (System.Windows.Forms.FormWindowState) (2);//After recording the initial position and size of the control, then maximize
0-normalize, 1-minimize,2-maximize
}
private void AddControl (Control ctl)
{
foreach (Control c in CTL.) Controls)
{//** is placed here, the control's child controls are first recorded, and the control itself is recorded
if (C.controls.count > 0)
AddControl (c);//The remaining controls in the window may also nest controls (such as a panel) and be extracted separately, as they are called recursively
Controlrect Objctrl;
Objctrl.left = C.left; Objctrl.top = C.top; Objctrl.width = C.width; Objctrl.height = C.height;
Oldctrl.add (Objctrl);
* * Here, the control itself is recorded before the control's child controls are recorded
if (C.controls.count > 0)
AddControl (c);//The remaining controls in the window may also nest controls (such as a panel) and be extracted separately, as they are called recursively
}
}
(3.2) Control adaptive size,
public void Controlautosize (Control mform)
{
if (Ctrlno = = 0)
{//* If the original size and position of the control are recorded in the Form1_Load of the form, there is no problem, but there is a problem with adding skins, because some controls, such as DataGridView, have not been completed and the number of child controls is small
* To record the original size and position of the control in the form's form1_sizechanged, the first time the size is changed, all the control's child controls have been formed
Controlrect CR;
Cr.left = Mform.left; Cr.top = Mform.top; Cr.width = Mform.width; Cr.height = Mform.height;
Cr.left = 0; cr.top = 0; Cr.width = MForm.PreferredSize.Width; Cr.height = MForm.PreferredSize.Height;

Oldctrl.add (CR);//The first one is "form itself", only one time
AddControl (mform);//The remaining controls within the window may nest other controls (such as a panel), so they are drawn separately for recursive invocation
}
float Wscale = (float) mform.width/(float) oldctrl[0]. width;//the proportions between the old and new forms, with the oldest old form
float Hscale = (float) mform.height/(float) oldctrl[0]. height;//. Height;
Ctrlno = 1;//enters = 1, No. 0 is the form itself, the control in the window, starting with ordinal 1
Autoscalecontrol (Mform, Wscale, Hscale);//The remaining controls in the window may also nest controls (such as a panel) and be extracted separately, as they are called recursively
}
private void Autoscalecontrol (Control ctl, float wscale, float hscale)
{
int ctrLeft0, ctrTop0, CtrWidth0, ctrHeight0;
int Ctrlno = 1;//1th is the left,top,width,height of the form itself, so the form control starts with Ctrlno=1
foreach (Control c in CTL.) Controls)
{//** is placed here, the control's child controls are scaled first, and the control itself is scaled back
if (C.controls.count > 0)
Autoscalecontrol (c, Wscale, Hscale);//The remaining controls in the window may also nest controls (such as a panel) and be extracted separately, as they are called recursively
CtrLeft0 = Oldctrl[ctrlno]. Left;
CtrTop0 = Oldctrl[ctrlno]. Top;
CtrWidth0 = Oldctrl[ctrlno]. Width;
CtrHeight0 = Oldctrl[ctrlno]. Height;
C.left = (int) ((ctrleft0-wleft0) * Wscale) + wleft1;//linear scale between old and new controls
C.top = (int) ((ctrtop0-wtop0) * h) + wTop1;
C.left = (int) ((ctrLeft0) * wscale);//linear scale between old and new controls. The control position is relative to the form, so you cannot add + wLeft1
C.top = (int) ((ctrTop0) * hscale);//
C.width = (int) (CTRWIDTH0 * wscale);//is only related to the initial size, so it cannot be multiplied by the current width (int) (C.width * W);
C.height = (int) (CTRHEIGHT0 * hscale);//
ctrlno++;//Cumulative serial Number
* * Here, it is the child controls that scale the control itself before scaling the control
if (C.controls.count > 0)
Autoscalecontrol (c, Wscale, Hscale);//The remaining controls in the window may also nest controls (such as a panel) and be extracted separately, as they are called recursively

if (CTL is DataGridView)
{
DataGridView DGV = ctl as DataGridView;
Cursor.current = Cursors.waitcursor;

int widths = 0;
for (int i = 0; i < DGV. Columns.count; i++)
{
DGV. AutoResizeColumn (i, datagridviewautosizecolumnmode.allcells); Automatically adjust column widths
Widths + = DGV. Columns[i]. Width; Calculates the width of the cell column after the adjustment column and
}
if (Widths >= ctl. Size.width)//If the width of the adjustment column is greater than the Set column width
DGV. autoSizeColumnsMode = Datagridviewautosizecolumnsmode.displayedcells; Adjust the mode of a column automatically
Else
DGV. autoSizeColumnsMode = Datagridviewautosizecolumnsmode.fill; If it is less than the fill

Cursor.current = Cursors.Default;
}
}
}

}

Step Two:

private void Form_sizechanged (object sender, EventArgs e)
{
Asc.controlautosize (this);
}

private void Form_Load (object sender, EventArgs e)
{

Asc.controllinitializesize (this);

}

Step three: Note some of the settings for the control

Label AutoSize set to True if the parent container panel is set, the AutoSize of the panel is true

Panel/picturebox has background image backgroundimage, BackgroundImageLayout set to Stretch;picturebox if set image, then set SizeMode: StretchImage
