TableLayoutPanel and AutoScroll - c#

I have a TableLayoutPanel to which I add rows dynamically.
Each row has an absolute size.
I set the AutoScroll to "true", but when I add rows that go out of the display of the TableLayoutPanel, I don't see the scroll.
This is the designer code:
namespace WindowsFormsApplication1
{
partial class Form1
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.tableLayoutPanel1 = new System.Windows.Forms.TableLayoutPanel();
this.button1 = new System.Windows.Forms.Button();
this.SuspendLayout();
//
// tableLayoutPanel1
//
this.tableLayoutPanel1.AutoScroll = true;
this.tableLayoutPanel1.CellBorderStyle = System.Windows.Forms.TableLayoutPanelCellBorderStyle.Single;
this.tableLayoutPanel1.ColumnCount = 1;
this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 50F));
this.tableLayoutPanel1.Location = new System.Drawing.Point(24, 48);
this.tableLayoutPanel1.Name = "tableLayoutPanel1";
this.tableLayoutPanel1.RowCount = 1;
this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, 50F));
this.tableLayoutPanel1.Size = new System.Drawing.Size(239, 163);
this.tableLayoutPanel1.TabIndex = 0;
//
// button1
//
this.button1.Location = new System.Drawing.Point(24, 10);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(239, 28);
this.button1.TabIndex = 1;
this.button1.Text = "button1";
this.button1.UseVisualStyleBackColor = true;
this.button1.Click += new System.EventHandler(this.button1_Click);
//
// Form1
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(292, 266);
this.Controls.Add(this.button1);
this.Controls.Add(this.tableLayoutPanel1);
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);
}
#endregion
private System.Windows.Forms.TableLayoutPanel tableLayoutPanel1;
private System.Windows.Forms.Button button1;
}
}
and this is how I add rows:
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
tableLayoutPanel1.RowCount++;
tableLayoutPanel1.RowStyles.Add(new RowStyle(SizeType.Absolute, 30));
Button b = new Button();
tableLayoutPanel1.Controls.Add(b, 0, tableLayoutPanel1.RowCount - 1);
}
}
}
Does anybody know what's going on?
thanks :)

Set the AutoScroll property to True.
Make sure that the default rows that get added by the designer do not cause any trouble. Make your constructor look like this:
public Form1() {
InitializeComponent();
tableLayoutPanel1.RowCount = 0;
tableLayoutPanel1.RowStyles.Clear();
tableLayoutPanel1.AutoScroll = true;
}

Looks like you're missing tableLayoutPanel.AutoSize = true.

Try the below line which may work for you:
this.tableLayoutPanel1.AutoScroll = true;
this.tableLayoutPanel1.Dock = DockStyle.Top;

Why aren't the generated buttons showing in the FlowLayoutPanel?

So, I'm trying to create an accordion with dynamically loaded buttons. In the future, the title of the buttons will change depending on the details I've retrieved from somewhere. For now, what I'm trying to do is to load buttons to look like these:
I've tried doing the following below:
// Forms1.cs
using System;
using System.Drawing;
using System.Windows.Forms;
namespace WindowsFormsApp1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
int buttonCount = 3;
var buttons = new FontAwesome.Sharp.IconButton[buttonCount];
for (int i = 0; i < buttonCount; i++)
{
var btn = new FontAwesome.Sharp.IconButton
{
Text = "Button " + i,
TextAlign = ContentAlignment.MiddleLeft,
IconChar = FontAwesome.Sharp.IconChar.Book,
IconColor = ColorTranslator.FromHtml("#6A6A73"),
IconSize = 20,
IconFont = FontAwesome.Sharp.IconFont.Auto,
TextImageRelation = TextImageRelation.ImageBeforeText,
FlatStyle = FlatStyle.Flat
};
btn.FlatAppearance.BorderSize = 0;
btn.ForeColor = ColorTranslator.FromHtml("#6A6A73");
btn.BackColor = ColorTranslator.FromHtml("#FDFEFF");
btn.Dock = DockStyle.Top;
buttons[i] = btn;
}
flowLayoutPanel1.Controls.AddRange(buttons);
}
}
}
// Forms1.Designer.cs
namespace WindowsFormsApp1
{
partial class Form1
{

protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code
/// <summary>

{
this.flowLayoutPanel1 = new System.Windows.Forms.FlowLayoutPanel();
this.SuspendLayout();
//

this.flowLayoutPanel1.BackColor = System.Drawing.SystemColors.ControlLight;
this.flowLayoutPanel1.Dock = System.Windows.Forms.DockStyle.Left;
this.flowLayoutPanel1.Location = new System.Drawing.Point(0, 0);
this.flowLayoutPanel1.Name = "flowLayoutPanel1";
this.flowLayoutPanel1.Size = new System.Drawing.Size(200, 450);
this.flowLayoutPanel1.TabIndex = 0;
//

//

this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(800, 450);
this.Controls.Add(this.flowLayoutPanel1);
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);
}
#endregion
private System.Windows.Forms.FlowLayoutPanel flowLayoutPanel1;
}
}
Here's what it looks like after building and running the application:
What am I doing wrong?
Form1_Load method is not subscribed to Load event of your form. Body of InitializeComponent is missing following line of code.
this.Load += new System.EventHandler(this.Form1_Load);
Insert this line before this.ResumeLayout(false);. You can fix it in designer as well.

how to disable part ToolStripSplitButton

I would like to disable the button part of a ToolStripSplitButton in a c# winforms app. As far as I see it is not possible and I would like to avoid a complex solution (rewriting entire toolstripsplitbutton) so I'm trying to disable visually at least, ie. draw a grayed icon when button part disabled.
First I browsed referencesource and found that ToolStripRenderer and ToolStripProfessionalRenderer uses some 'internal' properties and methods in OnRenderItemImage(ToolStripItemImageRenderEventArgs e) so I cannot mimic (copy-and-modify-a-bit) the behaviour of OnRenderItemImage.
Next I tried the following code.
Basically it works, the toolStripSplitButton1 is grayed out when the Tag is boolean false.
But this solution kills all my System.Windows.Forms.Timer somehow! Try this code, when toolStripSplitButton1.Tag == false then the toolstrip-independent timer1 does not tick anymore. And the toolStripSplitButton1 tooltip does not show up (guess because it uses Timer as well).
(button1 and button1_Click is just for toggle toolStripSplitButton1.Tag)
My first question is why OnRenderItemImage kills all System.Windows.Forms.Timer?
Second question is how to achieve the original aim to gray out button icon at least visually independently of the button itself?
using System;
using System.Windows.Forms;
namespace WindowsFormsApplication
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
toolStrip1.Renderer = new MyToolStripProfessionalRenderer();
toolStripSplitButton1.Tag = false; // this is for disabling button part
toolStripSplitButton1.ToolTipText = "toolStripSplitButton1 ToolTip";
System.Windows.Forms.Timer timer1 = new Timer();
timer1.Interval = 1000;
timer1.Tick += T_Tick;
timer1.Start();
}
int ticks = 0;
private void T_Tick(object sender, EventArgs e)
{
System.Diagnostics.Debug.WriteLine(ticks++);
}
private void button1_Click(object sender, EventArgs e)
{
toolStripSplitButton1.Tag = !((bool)toolStripSplitButton1.Tag);
}
}

{
protected override void OnRenderItemImage(ToolStripItemImageRenderEventArgs e)
{
try
{
if (e.Item.Enabled &&
e.Item.Tag?.GetType() == typeof(bool) &&
!(bool)e.Item.Tag)
{
e.Item.Enabled = false;
base.OnRenderItemImage(e);
e.Item.Enabled = true;
}

base.OnRenderItemImage(e);
}
catch (Exception ex)

// this never reached, there's no exceptions

I don't think that using a timer for tracking the change is a good idea. What I suggest is create a changeOccurred event and do the operations inside the event.

How to capture screenshot without user32.dll which is unmanaged code

Overview
I am trying to capture a screenshot of external application and load the image to a .NET PictureBox.
user32.dll Unmanaged Code
There are a bunch of examples using user32.dll an I am looking for a .NET answer that does not use the user32.dll file.
App #1
I have provided sample code below that I am using for demonstration purposes. When the program is executed, it parses Processes and saves ones with valid window titles to the drop-down list.
When you select the app name from the drop-down list and click the button, it will try to capture the screenshot app and load into the .NET PictureBox.

This is the code I came up with to take a screenshot of an application without using user32.dll.
To make the app active, and wait for 20 to make sure it has completed.
Microsoft.VisualBasic.Interaction.AppActivate(ProcessId);
Threading.Thread.Sleep(20);
To capture the active window, I used the following. Added a delay of 200, then convert the clipboard object to an image.
SendKeys.SendWait("%{PRTSC}");
Threading.Thread.Sleep(200);
IDataObject objData = Clipboard.GetDataObject();

How to prevent tearing when scrolling TableLayoutPanel?

I think vertical tearing is the proper term to describe what I'm seeing but here is an screenshot that shows the issue:
I thought the DoubleBuffered property could help with this but it neither setting it on my Form or inheriting TableLayoutPanel and setting it in the constructor seem to have any effect.
I apologize for the following long block of code, but I felt I should include a complete example that demonstrates the issue. You should just be able to copy it and run it to replicate my issue:
public class ScrollTearingDemo : Form
{
private const int ROW_COUNT = 20;
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]

{

}

Remove the title bar in Windows Forms

How can I remove the blue border that's on top of the Window Form? (I don't know the name of it exactly.)
You can set the Property FormBorderStyle to none in the designer,
or in code:
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
if by Blue Border thats on top of the Window Form you mean titlebar, set Forms ControlBox property to false and Text property to empty string ("").
here's a snippet:
this.ControlBox = false;
this.Text = String.Empty;

			
				
Also add this bit of code to your form to allow it to be draggable still.
Just add it right before the constructor (the method that calls InitializeComponent()
private const int WM_NCHITTEST = 0x84;
private const int HTCLIENT = 0x1;
private const int HTCAPTION = 0x2;
///
/// Handling the window messages
///
protected override void WndProc(ref Message message)
{
base.WndProc(ref message);
if (message.Msg == WM_NCHITTEST && (int)message.Result == HTCLIENT)
message.Result = (IntPtr)HTCAPTION;
}
That code is from: https://jachman.wordpress.com/2006/06/08/enhanced-drag-and-move-winforms-without-having-a-titlebar/
Now to get rid of the title bar but still have a border combine the code from the other response:
this.ControlBox = false;
this.Text = String.Empty;
with this line:
this.FormBorderStyle = FormBorderStyle.FixedSingle;
Put those 3 lines of code into the form's OnLoad event and you should have a nice 'floating' form that is draggable with a thin border (use FormBorderStyle.None if you want no border).
Me.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None
Set FormsBorderStyle of the Form to None.
If you do, it's up to you how to implement the dragging and closing functionality of the window.
I am sharing my code.
