How to avoid flickering in TableLayoutPanel in C # .net

Question

I use TableLayoutPanel for attendance labeling purposes. I added controls (panel and shortcut) inside this TableLayoutPanel and created events for them. In some conditions, I cleared all the controls and started linking the same controls in different positions of the TableLayoutPanel. When you re-bind controls, the TableLayoutPanel flickers and initializes too slowly.

Answer 1

Pause the layout until you add all of your controls.

TableLayoutPanel panel = new TabelLayoutPanel(); panel.SuspendLayout(); // add controls panel.ResumeLayout(); 

Also look at the use of double buffering. You will need to subclass the TableLayoutPanel class. An example is here .

This worked great for me. Remove flicker due to window-shaped TableLayoutPanel & Panel

Here is what is in this link (literally copied)

To completely remove flicker due to TableLayoutPanel & Panel in the window form, follow these steps: = - 1. Set the double buffering property of the form = true. 2. Insert the following 2 functions in form.cs

 #region .. Double Buffered function .. public static void SetDoubleBuffered(System.Windows.Forms.Control c) { if (System.Windows.Forms.SystemInformation.TerminalServerSession) return; System.Reflection.PropertyInfo aProp = typeof(System.Windows.Forms.Control).GetProperty("DoubleBuffered", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance); aProp.SetValue(c, true, null); } #endregion #region .. code for Flucuring .. protected override CreateParams CreateParams { get { CreateParams cp = base.CreateParams; cp.ExStyle |= 0x02000000; return cp; } } #endregion 

3. Call SetDoubleBuffered("TableLaoutPannel_controlName") for each TableLayoutPannel , Pannel , Splitcontainer , Datagridview and all container controls.

Use this panel to set the dBuffer property to true.

 public partial class MyTableLayoutPanel : TableLayoutPanel { public MyTableLayoutPanel() { InitializeComponent(); } public MyTableLayoutPanel(IContainer container) { container.Add(this); InitializeComponent(); } /// <summary> /// Double buffer /// </summary> [Description("Double buffer")] [DefaultValue(true)] public bool dBuffer { get { return this.DoubleBuffered; } set { this.DoubleBuffered = value; } } }

VB.net:

  Protected Overrides ReadOnly Property CreateParams() As CreateParams Get Dim cp As CreateParams = MyBase.CreateParams cp.ExStyle = cp.ExStyle Or &H2000000 Return cp End Get End Property 

FROM#:

  protected override CreateParams CreateParams { get { CreateParams cp = base.CreateParams; cp.ExStyle = cp.ExStyle | 0x2000000; return cp; } } 

In VB, add it to the end of the affected class, and I assure you that this will work.

In C # add a property to the top of the class along with your other properties.

Essentially, it expects full rendering of Winform and removes the flickering of the shape drawn on the screen. If you have not tested it, please do not neglect it. I had a huge problem with winform delay, and this fixed it.

Answer 5

This code, presented on another question, nailed it; it uses an API call to set the TableLayoutPanel redraw.

Answer 6

There is another alternative that I ended up using, since quite a lot of my user interface used transparency for background colors. I understand that this significantly reduces performance in WINFORMS. However, this does not apply to WPF applications (usually not visible as flicker), so conversion can be useful.

Answer 7

 //Call this function on form load. SetDoubleBuffered(tableLayoutPanel1); public static void SetDoubleBuffered(System.Windows.Forms.Control c) { if (System.Windows.Forms.SystemInformation.TerminalServerSession) return; System.Reflection.PropertyInfo aProp = typeof(System.Windows.Forms.Control).GetProperty("DoubleBuffered", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance); aProp.SetValue(c, true, null); } 

// The double-buffered solution works fine for the table layout pane, and no flickering occurs

Answer 8

As an improvement to the above, I had better results:

  TableLayoutPanel panel = new TabelLayoutPanel(); panel.SuspendLayout(); panel.StopPaint(); // add controls panel.ResumePaint(); panel.ResumeLayout();
