Hi,

The cells in the DataGidViewCheckBoxColumn are of type DataGirdViewCheckBoxCell. So, you cannot cast directly DataGirdViewCheckBoxCell to checkbox. instead you can use DataGirdViewCheckBoxCell itself.

refer this link for more on DataGirdViewCheckBoxCell.

Set DataGridViewCheckBoxCell Value to True[^]
DataGridViewCheckBoxCell Class[^]

Hope it helps.

Hi,
Why you want to typecast that? You can directly fetch the value.
Try this:

C#

foreach (DataGridViewRow dataGridRow in dataGridView1.Rows)
{
   if (dataGridRow.Cells["YourCheckboxColumn"].Value != null &&    (bool)dataGridRow.Cells["YourCheckboxColumn"].Value)
  {
         // Checked
  }
  else if (dataGridRow.Cells["YourCheckboxColumn"].Value == null)
  {
         // Unchecked
  }
}
