Dear Friend
Help me!
I have five datagridview in a windows form.each datagridview contains first column of checkbox column.I match certain criteria pragmatically and set value for checkbox column true.When i debug program i see that code hit ...r2.cells[0].value =true ..but visually not changed.only first datagridview checkbox vaue change visually remain unchanged.
Please help me what i am doing wrong.
Code is as below..
#region Dhulai Labour(Only dgvlgodawn is checked visually too)
DataTable dt2 = Mst.LabourWork(1, dt.Rows[0]["lot_Nos"].ToString());
if (dt2.Rows.Count > 0)
{
for (int i = 0; i <= dt2.Rows.Count - 1; i++)
{
foreach (DataGridViewRow r in dgvLGodawn.Rows)
{
if (r.Cells[1].Value.ToString() == dt2.Rows[i]["labourid"].ToString())
{
r.Cells[0].Value = true;
r.Cells[3].Value = decimal.Parse(dt2.Rows[i]["wagesamount"].ToString());
}
}

推荐答案
直接在datagridview数据源上工作，因为这提供了某种映射
就像那样
work directly on the datagridview datasource as this provide some kind of mapping
like that
foreach (DataRow row in ((DataTable)dataGridView1.DataSource).Rows)
{
row["Check"]=true;
}
