Try this, It may help you:-

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            CheckBox chk = (CheckBox)(e.Row.FindControl("CheckBoxId"));

            If(chk.Text == "MyName")
             {
               chk.Checked = true;
             }

Solution 2

If you want to check in button click event then cod eshould be like this:-

C#

for (int i = 0; i < GridView1.Rows.Count; i++)
        {
            CheckBox chk = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("CheckBox1");

                if (chk.Checked)
                {
                   //your logic
                }

         }

Here in Cells[index], your index is the position of your checkbox column location.

Hope you find your solution.
Fun coding....

Solution 3

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
  }
}
