I want to fill data on button click event from DataGridView Control:

My code like this
for (int i = 0; i < dgv_EmpAttList.Columns.Count; i++)
{
txt_EnrollNo.Text = this.dgv_EmpAttList.CurrentRow.Cells[i].Value.ToString();
txt_FirstInTime.Text = this.dgv_EmpAttList.CurrentRow.Cells[i].Value.ToString();
txt_LastOutTime.Text = this.dgv_EmpAttList.CurrentRow.Cells[i].Value.ToString();
txt_TotalHours.Text = this.dgv_EmpAttList.CurrentRow.Cells[i].Value.ToString();
}
Looping through your columns probably won’t help here.
Try assigning each textbox the cell that it is mapped to:
