Hide and show winform TableLayout Row via c #
screen2_Mar31.jpg Screen3_Mar31.jpg I designed the TableLayout with four rows, since the first row should always be visible, while the last row exists with the Add label so that the intermediate rows are hidden, when the user clicks the Add button, he needs to sequentially show hidden rows for first click 1,2, 4th row to be shown, and for second rows of clicks 1,2,3 will be visible, and row 4 (which contains "Add" to hide)
but I saw that the controls created on the second and third lines move to the fourth line, hiding those lines,
please help me fix the above, thanks in advance,
private void linkLabel2_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
for (int i = 1; i < tableLayoutPanel15.RowCount - 1; i++)
{
if (tableLayoutPanel15.RowStyles[i].Height == 0)
{
if (i == 1)
{
tableLayoutPanel15.RowStyles[i - 1] = new RowStyle(SizeType.Percent, 50f);
tableLayoutPanel15.RowStyles[i] = new RowStyle(SizeType.Percent, 50f);
cmb_DrawnBy2.Visible = true;
cmb_percentageBy2.Visible = true;
}
else
{
tableLayoutPanel15.RowStyles[i - 2] = new RowStyle(SizeType.Percent, 33.33f);
tableLayoutPanel15.RowStyles[i - 1] = new RowStyle(SizeType.Percent, 33.33f);
tableLayoutPanel15.RowStyles[i] = new RowStyle(SizeType.Percent, 33.33f);
tableLayoutPanel15.RowStyles[i + 1] = new RowStyle(SizeType.Percent, 0);
}
break;
}
}
}

There is no need to use a loop in your script for
if I understand correctly. You can do it in a simple and straightforward way with an expression switch
. Have a look at this code which I reproduced based on your description
int visibleRow = 1;
private void LinkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
switch(visibleRow++)
{
case 1:
comboBox2.Visible = true;
numericUpDown2.Visible = true;
break;
case 2:
comboBox3.Visible = true;
numericUpDown3.Visible = true;
linkLabel1.Visible = false;
break;
}
}
Here is:
comboBox1
and numericUpDown1
belong to line number 1
comboBox2
and numericUpDown2
belong to line # 2
comboBox3
and numericUpDown3
belong to line number 3
linkLabel1
belongs to line number 4
And this is how I formatted the table layout control
namespace WindowsFormsApp4
{
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);
}

/// the contents of this method with the code editor.
