我有 3 个 DatagridviewCheckboxCell 并使用此代码检查它们:
foreach (DataGridViewRow row in dataGridView1.Rows)
{
DataGridViewCheckBoxCell chk1 = (DataGridViewCheckBoxCell)row.Cells["Column6"];
DataGridViewCheckBoxCell chk2 = (DataGridViewCheckBoxCell)row.Cells["Column7"];
DataGridViewCheckBoxCell chk3 = (DataGridViewCheckBoxCell)row.Cells["Column8"];
string commande2 = "SELECT id_pres from Fonct_Prest where id_fonc = @id";
OleDbCommand cmd2 = new OleDbCommand(commande2, con);
cmd2.Parameters.AddWithValue("@id", row.Cells["Code"].Value);
dt2.Load(cmd2.ExecuteReader());
for (int i = 0; i < dt2.Rows.Count; i++)
{
if (dt2.Rows[i][0].ToString() == "1")
{
chk1.Value = true;
}
if (dt2.Rows[i][0].ToString() == "2")
{
chk2.Value = true;
}
if (dt2.Rows[i][0].ToString() == "6")
{
chk3.Value = true;
}
}
cmd2.Parameters.Clear();
dt2.Rows.Clear();
}
此代码工作正常,但在 datagridview 的第一行未选中复选框。我的代码中的错误在哪里?
