- Declare Data table in global;
- Datatable hold temporary data;
DataTable dt = new DataTable();
- create column to datatable “dt”.
dt.Columns.Add("id");
dt.Columns.Add("name");
- Create temporary data and stored to datatable “dt”;
for (int i = 1; i < 21; i++)
{
dt.Rows.Add(DateTime.Now.ToString("hhmmssffffff")+"-"+i,
"Juan"+i+" Tamad"+i);
}
- Create/Add CheckBox in datagridview.
DataGridViewCheckBoxColumn checkColumn = new DataGridViewCheckBoxColumn();
checkColumn.Name = "Selection";
checkColumn.HeaderText = "Selection";
checkColumn.Width = 50;
checkColumn.ReadOnly = false;
checkColumn.FillWeight = 10;
dataGridView1.Columns.Add(checkColumn);
- Display date with button in datagridview;
dataGridView1.DataSource = dt;
- Hide button in datagridview or hide column in “Button”
dataGridView1.Columns[0].Visible = false;
- Show button in datagridview or hide column in “Button”
dataGridView1.Columns[0].Visible = true;
