Dynamically update button

I am attempting to dynamically add a list of buttons:
private void updateClientListUI()
{
if (this.InvokeRequired)
{
this.Invoke(new MethodInvoker(this.updateClientListUI));
}
else
{
int count = 1;
int x = 0;
int y = 0;
for (int i = 0; i < 5; i++)
{
Button btn = new Button();
btn.Text = count.ToString();
btn.Name = count.ToString();
btn.Size = new Size(35, 35);
btn.Location = new Point(150, 150 * y);
//btn.Dock = DockStyle.Fill;
y++;
count++;
Controls.Add(btn);
}
}
}
Unfortunately this does not apply any buttons to the form.
In addition I was wondering how could I append these buttons in a panel called subPanelClient

This worked for me, the issue was the position of the button, as you have to indicate it within a panel or form.
In this case i just docked them to the panel
private void updateClientListUI()
{
if (this.InvokeRequired)
{
this.Invoke(new MethodInvoker(this.updateClientListUI));
}
else
{
//Debug.WriteLine(clientNames[0]);
int basex = subPanelClient.Location.X;
int basey = subPanelClient.Location.Y;
subPanelClient.Controls.Clear();
Debug.WriteLine(clientNames.Count);
for (int i = 0; i < clientNames.Count; i++)
{
Button b = new Button();
b.Left = basex;
b.Top = basey;
b.Size = new Size(25, 25); // <== add this line
b.Dock = DockStyle.Top;
b.ForeColor = Color.Gainsboro;
b.FlatStyle = FlatStyle.Flat;
b.FlatAppearance.BorderSize = 0;
b.Padding = new Padding(35, 0, 0, 0);
b.TextAlign = ContentAlignment.MiddleLeft;
basey += 25;
b.Name = clientNames[i];
b.Text = clientNames[i];
subPanelClient.Controls.Add(b);
buttonsAdded.Insert(i, b);
}
}
}

Custom groupbox control not painting correctly when added to tabpage

I have a groupbox which I created a custom paint event for so that I
can control the border color.
It works great when the groupbox is on a form but when the groupbox is
on a tabpage, the control does not paint properly. Everything is blurry
and the child controls inside the groupbox are also blurry and get a border
drawn.
Any gentle help would be greatly appreciated!
Thanks,
Dan

Custom MessageBox with custom-defined Buttons [duplicate]

I am doing C# application, and I want to change the style of a message box. Is it possible or not?
Example: change button style, fore color, etc.

You can't restyle the default MessageBox as that's dependant on the current Windows OS theme, however you can easily create your own MessageBox. Just add a new form (i.e. MyNewMessageBox) to your project with these settings:
FormBorderStyle FixedToolWindow
ShowInTaskBar False
StartPosition CenterScreen
To show it use myNewMessageBoxInstance.ShowDialog();. And add a label and buttons to your form, such as OK and Cancel and set their DialogResults appropriately, i.e. add a button to MyNewMessageBox and call it btnOK. Set the DialogResult property in the property window to DialogResult.OK. When that button is pressed it would return the OK result:
MyNewMessageBox myNewMessageBoxInstance = new MyNewMessageBox();
DialogResult result = myNewMessageBoxInstance.ShowDialog();
if (result == DialogResult.OK)
{
// etc
}
It would be advisable to add your own Show method that takes the text and other options you require:
public DialogResult Show(string text, Color foreColour)
{
lblText.Text = text;
lblText.ForeColor = foreColour;
return this.ShowDialog();
}

MessageBox::Show uses function from user32.dll, and its style is dependent on Windows, so you cannot change it like that, you have to create your own form

Here is the code needed to create your own message box:

Restrict the numbers of controls in a winform

i have a button in my form and for every button click it is adding groupBox. but i want a winform contain only 8 groupboxes. when the numbers of groupBox reach 8 it will automatically do Visible=false all 8 before groupBox and again adds a groupBox named(groupBox9). what must i do?

}
}
}

define an integer class variable and increase it everytime the button is clicked. After increasing it, check if it's greater than 8. If it is, set your stuff to Visible = false.
Mock up:
public class MyClass
{
private int groupboxCounter = 0;
public MyClass()
{
}
private void btn_click(...)
{
// add a new groupbox here
groupboxCounter++;
if (groupboxCounter > 8)
{
//make stuff invisible here
}
}
}

TableLayoutPanel changing it's sizing

I have a few tablelayoutpanels in my program in order to lay out different controls in rows. Until recently these were all working correctly, but after a change in server this is no longer the case. A potential cause is a change in screen resolution as I noticed similar problems on other computers running my program.
An example of this problem is shown below
Before the data rows are loaded (from database), the sizing is incorrect. A measurement using the VS designer shows that the size in figure 2 is correct. Interestingly, if I add a blank row to this table then the resizing doesn't happen.
public JobOpMainTable()
{
DoubleBuffered = true;
AutoSize = true;
AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowAndShrink;
DoubleBuffered = true;
BackColor = Color.White;
CellBorderStyle = TableLayoutPanelCellBorderStyle.Single;
headers();
}
private void headers()
{
string[] names = { "Operation", "Est Lab Hrs", "Est UM Hrs", "Act Lab Hrs", "Act UM Hrs" };
for (int i = 0; i < names.Length; i++) header(names[i], i);
}
private void header(string name, int col)
{
Panel pan = new Panel();
pan.Width = widths[col];
pan.Height = 25;
pan.BackColor = Color.Black;
pan.Dock = DockStyle.Fill;
pan.Margin = new System.Windows.Forms.Padding(0);
TextBox txt = new TextBox();
txt.Font = new System.Drawing.Font("Microsoft sans serif", 8, FontStyle.Bold);
txt.Text = name;
txt.ReadOnly = true;
txt.BackColor = Color.Black;
txt.ForeColor = Color.White;
txt.Dock = DockStyle.Fill;
txt.BorderStyle = System.Windows.Forms.BorderStyle.None
pan.Controls.Add(txt);
Controls.Add(pan, col, 0);
}
private int newRow()
{
int row = Controls.Count / 5;
for (int i = 0; i <= 4; i++)
{
TextBox txt = new TextBox();
txt.Width = widths[i];
txt.BackColor = Color.White;
txt.BorderStyle = System.Windows.Forms.BorderStyle.None;
txt.ReadOnly = true;
txt.Dock = DockStyle.Fill;
txt.Margin = new Padding(0);
txt.Enter += new EventHandler(enterCell);
txt.Leave += new EventHandler(leaveCell);
Controls.Add(txt, i, row);
}
return row;
}
Above is the code I believe is relevant to the problem. The resizing occurs the first time newRow() is called when loading in data: each new box makes the column wider. Again though, the odd thing is this doesn't occur if I add a row from the constructor
