Place a grid of labels on a form

Place a grid of labels on a form - c#

I'm trying to place a grid of labels on my winforms app. First, I'm populating a list of label objects of size (200 x 50) and then trying to place them so that when x reaches the width of the form (581), I increment y by 50 + 1
Here is my code:
private List<Label> _labels;
private int xOffset = 10;
private int yOffset = 10;
public Form1()
{
InitializeComponent();
_labels = new List<Label>();
for(var i = 0; i <= 20; i++)
_labels.Add(new Label() { Name = "lbl" + i, Height = 50, Width = 200, MinimumSize = new Size(200, 50), BorderStyle = System.Windows.Forms.BorderStyle.Fixed3D, Text = "Label "+i});
// 581, 517
var x = 0;
var y = 0;
foreach (var lbl in _labels)
{
if (x >= 580)
{
x = 0;
y = y + lbl.Height + 2;
lbl.Location = new Point(x, y);
}
this.Controls.Add(lbl);
x += x + lbl.Width;
}
}
It's only placing the even labels from the list on new lines. I'm not sure what I'm doing wrong.
I'm trying to place all of the labels in a grid like design. When one row is full, go to the next row and continue placing labels from the list on that new "row"

You need to move the Location setting code out of the resetting loop:
foreach (var lbl in _labels)
{
if (x >= 580)
{
x = 0;
y = y + lbl.Height + 2;
}
lbl.Location = new Point(x, y);
this.Controls.Add(lbl);
x += lbl.Width;
}

The problematic part is here
x += x + lbl.Width; //+= x
change it to
x += lbl.Width;
Get the
lbl.Location = new Point(x, y);
out of the if statement
if (x >= 580)
{
x = 0;
y = y + lbl.Height + 2;
//lbl.Location = new Point(x, y);
}
lbl.Location = new Point(x, y);
this.Controls.Add(lbl);
x += lbl.Width;

Try this using a Docked FlowLayoutPanel:
public partial class Form1 : Form
{
List<Label> labels;
public Form1()
{
InitializeComponent();
this.labels=new List<Label>();
AddLabelsToFrom(20);
}
void AddLabelsToFrom(int count)
{
for (int i=0; i<count; i++)
{
var lbl=new Label() { Name="lbl"+i, Height=50, Width=200, MinimumSize=new Size(200, 50), BorderStyle=System.Windows.Forms.BorderStyle.Fixed3D, Text="Label "+i };
labels.Add(lbl);
flowLayoutPanel1.Controls.Add(lbl);
}
}
}

void SetGridLabel()
{
for (int i = 0; ; i++)
{
for (int j = 0; ; j++)
{
Label L = new Label();
L.TextAlign = ContentAlignment.MiddleCenter;
L.AutoSize = false;
L.Size = new Size(70, 70);
L.Text = "Test_" + j + "_" + i;
L.Location = new Point(j * L.Size.Width, i * L.Size.Height);
if ((i + 1) * L.Size.Height > this.Size.Height)
return;
if ((j + 1) * L.Size.Width > this.Size.Width)
break;
this.Controls.Add(L);
}
}
}

private List<Label> _labels;
public Form1()
{
InitializeComponent();
_labels = new List<Label>();
for (var i = 0; i <= 20; i++)
_labels.Add(new Label()
{
Name = "lbl" + i, Height = 50,Width = 200,
Size = MinimumSize = new Size(200, 50),
Location = new Point(i * 200 % 600, 50 * (i * 200 / 600)),
BorderStyle = System.Windows.Forms.BorderStyle.Fixed3D,
Text = "Label " + i
});
foreach (var lbl in _labels) this.Controls.Add(lbl);
}

c# adding New Button Depending on the # of items in mySQLWorkbench

This code adds new buttons depending on the # of items saved on my items table.
mySQL WorkBench
I dont know why it keeps on duplicating my buttons. I just want to keep the buttons arranged into 4 columns.
object[] itemDetail;
object[] itemLi = itemsWS.searchItem("", "drinks", "all");
int cleft = 0;
for (int i = 0; i < itemLi.Length; i++)
{
itemDetail = itemsWS.getItemInfo(itemLi[i].ToString());
for (int x = 35; x < 537; x++)
{
Button myButton = new Button();
myButton.Text = itemDetail[0].ToString();
myButton.Top = cleft * 80;
myButton.Left = 70;
myButton.Location = new Point(x, cleft);
myButton.Size = new Size(100, 60);
tabPage1.Controls.Add(myButton);
cleft = cleft + 15;
//cleft = cleft + 1;
x += 134;
}
}

try something like this:
int x = 35;
int cleft = 0;
foreach (var item in itemLi)
{
Button myButton = new Button();
myButton.Text = itemDetail[0].ToString();
myButton.Top = cleft * 80;
myButton.Left = 70;
myButton.Location = new Point(x, cleft);
myButton.Size = new Size(100, 60);
tabPage1.Controls.Add(myButton);
x += 134;
// Check if x is greater than form size,
// If so, resets x, and increments cleft
if (x >= 537)
{
x == 35;
cleft += 15
}
}
I'm not exactly sure what x and cleft are doing, but you get the idea (hopefully)

You can also put FlowLayoutPanel inside the Bread tabpage, then just set the Orientation property of the FlowLayoutPanel, then do Ben's suggestion without the Top, Left, Location, cleft, and x stuff so you won't need to set the location of the Buttons.

How to Print images on paper using PrintDocument

My problem is that is that my code prints the images overlapping each other. I do not know how to change the x and y positions. The printer should print 3 images per row and then move to the next row.

Desired output :
I am getting :
As you can see the last digit is overlapping. I want to draw it next to the previous one

I have observed the code and found the issue.. in panel1_print u are not incrementing the values properly..
I have made the required changes now u will get the 4 bar in a line and 5th one in another line - check the attached image.
just replace ur panel1_Paint with this new code thats it you can find the changes..
I have marked them as
//start changes by Deepak
..
..
..
//end changes by Deepak
and also declare two variables loopValX and loopValY as int

You Should do it with the help of a DataGridView (That Contains Images in a Column).
The Images Will Then Print in each new row or column (by modifying as your desire)
The Following Class will do your work by passing it the whole DataGridView And Header in its constructor.

Your position variables are being declared inside the loop, meaning that they are reset for each pass through the loop. Keep position variables for X and Y outside of the loop over serial and adjust it for the total width (and height, if you start a new row of barcodes) of each barcode.

Add "columns" of controls dynamically based on container height

I'm using vs2012 (C#) for my app and I'm looking for a way to add a label and textbox to a tabPage on my form, dynamically. But because the # of controls to be added could be larger than 10, I am also trying to add them in "columns" so the container control will only scroll horizontally, not vertically.
For instance, I'm trying to do something like this:
LabelControl LabelControl LabelControl LabelControl
TextboxControl TextboxControl TextboxControl TextboxControl
LabelControl LabelControl LabelControl LabelControl
TextboxControl TextboxControl TextboxControl TextboxControl
etc.
The "container" control is a TabPage, so I know I have to grab the height from that and use it. I am able to get the textboxes to render but am having difficulty with the label controls being on top, then the textboxes below.
Here's what I've got so far:
int height = tabPageBicycle.Height;
Point startLocation = new Point(0, 0);
int previousX = 0;
int previousY = 0;
int currentX = 0;
for (int x = 0; x < 75; x++)
{
Label label = new Label();
TextEdit text = new TextEdit();
label.Text = x.ToString();
text.Text = x.ToString();
label.Location = new Point(currentX, previousY);
tabPageBicycle.Controls.Add(label);
if ((height - previousY) < text.Height)
{
currentX += 100;
previousY = 0;
}
text.Location = new Point(currentX + text.Height + 5, previousY + 50);
previousX = text.Location.X;
previousY = text.Location.Y;
tabPageBicycle.Controls.Add(text);
}
Any clues as to what I am doing wrong?

Ended up figuring it out, after taking it line-by-line and seeing what was being done in the loop. Here's the final code I used....as always, I'm open to suggestions/comments/etc. on how to make it better/more efficient.
int labelY = 0;
int textY = 0;
int startX = 5;
int startY = 5;
int height = tabPageBicycle.Height;
Point startLocation = new Point(0, 0);
for (int x = 0; x < 75; x++)
{
Label label = new Label();
TextEdit text = new TextEdit();
label.AutoSize = true;
label.Text = x.ToString();
text.Text = x.ToString();
//Determine if the next set of controls will be past the height of the container.
//If so, start on the next column (change X).
if ((height - textY) < ((label.Height + 10) + text.Height))
{
startX += 125;
labelY = 0;
}
//Start of new column.
if (labelY == 0)
label.Location = new Point(startX, startY);
else
label.Location = new Point(startX, textY + label.Height + 10);
tabPageBicycle.Controls.Add(label);
labelY = label.Location.Y;
textY = labelY + 15;
text.Location = new Point(startX, textY);
textY = text.Location.Y;
tabPageBicycle.Controls.Add(text);
}
and the results:
I hope it helps someone else out!

Dynamically programming a grid consisting of 64 buttons (8x8)

I'm trying to create a chess game purely for my learning C# and chess. Just to start off with, I would like to create an 8x8 grid of buttons through code rather than the designer. This would save me hard coding each button individually.
A button array would seem a good way to start but I have no idea how to implement this.

You can create a "square" class:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
class Square:PictureBox
{
private bool color;
private char piece;
}
and define an array to make place for 8x8 squares.
public partial class Form1 : Form
{
Square[,] square = new Square[8, 8];
public Form1()
{
InitializeComponent();
int i, j;
for (i = 0; i < 8; i++)
{
for (j = 0; j < 8; j++)
{
this.square[i, j] = new Square();//Creating the chess object//

May be you ca use the code below to solve your problem. This code is of Windows Form application in C#. And for the control Button.
for (int i = 0; i< 8; i++)
{
for (int j = 0; j < 8; j++)
{
Button BtnNew = new Button;
BtnNew.Height = 80;
BtnNew.Width = 80;
BtnNew.Location = new Point(80*i, 80*j);
this.Controls.Add(BtnNew);
}
}

We Keep Coding

C# (C-Sharp) is a programming language developed by Microsoft that runs on the .NET Framework.

Place a grid of labels on a form - c#

You need to move the Location setting code out of the resetting loop: foreach (var lbl in _labels) { if (x >= 580) { x = 0; y = y + lbl.Height + 2; } lbl.Location = new Point(x, y); this.Controls.Add(lbl); x += lbl.Width; }
