How to get the checkbox in a datagridview control in C#?

In C#, you can use the following code to obtain the status of the checkbox in a DataGridView:

foreach (DataGridViewRow row in dataGridView1.Rows)
{
    DataGridViewCheckBoxCell checkBox = row.Cells["ColumnName"] as DataGridViewCheckBoxCell;
    if (checkBox != null && checkBox.Value != null)
    {
        bool isChecked = (bool)checkBox.Value;
        // 根据isChecked的值来进行相应的操作
    }
}

Replace “ColumnName” with the actual name of the column where the checkboxes are located. By iterating through each row and retrieving the status of the checkboxes in the corresponding column, you can achieve obtaining the status of all checkboxes in the DataGridView.
