I have two columns of type checkbox in a grid view. How when i check column1, column2 can become unchecked and vice-versa.
I try to write this code but i have many problems maybe:-

C#

Private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
   DataGridViewCheckboxCell Ch1= new DataGridViewCheckboxCel();
   DataGridViewCheckboxCell Ch2= new DataGridViewCheckboxCel();
   
   Ch1 = (DataGridViewCheckboxCell)dataGridView1.Rows[dataGridView1.CurrentRow.Index].Cells[0];
 Ch2 = (DataGridViewCheckboxCell)dataGridView1.Rows[dataGridView1.CurrentRow.Index].Cells[0];

   if(ch1.Value == null)
      ch1.Value = false;
   elseif(Ch2.Value != null)
      Ch2.Value = false;

  switch(ch1.Value.ToString())
  {
     Case 'True':
                Ch1.Value = false;
                breake;
     Case 'False':
                if(Convert.ToBoolean(Ch1.Value) == false)

I understand what you're trying to do, but i do not understand what kind of problems do you have.
On the other side, why do you need 2 columns? Vacation is a type of absence. So, why do you want to store that values into 2 different columns?
[EDIT]
Check this: Build a Custom RadioButton Cell and Column for the DataGridView Control
and
DataGridView Custom Column of Type ListView or CheckedListBox

I can recommend using a BindingSource, see A Detailed Data Binding Tutorial
A Detailed Data Binding Tutorial[^]

To get or set the value:

C#

private void DataGridView1CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
	switch (this.DataGridView1.Columns[e.ColumnIndex].Name)
	{
		case "Absence":
			bool flag = (bool)this.DataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value;
			this.DataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex + 1].Value = !flag;
			break;
		case "vacation":
			bool flag = (bool)this.DataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value;
			this.DataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex - 1].Value = !flag;
			break;
	}
}
