in my code behind:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataSet ds = new DataSet();
DataTable dt = new DataTable();
DataColumn dc = new DataColumn("Id");
DataColumn dc1 = new DataColumn("Name");
//DataColumn dc2 = new DataColumn("Id");
dt.Columns.Add(dc);
dt.Columns.Add(dc1);
// dt.Columns.Add(dc2);
ds.Tables.Add(dt);
Session["data"] = ds;
GridView1.DataBind();
}
}
protected void btnSave_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection("Data Source=GATE-PC\\SQLEXPRESS;Initial Catalog=dbProfile;Integrated Security=True");
con.Open();
foreach (GridViewRow row in GridView1.Rows)
{
SqlCommand cmdd = new SqlCommand("Insert into Profile (Id, profile_Id)VALUES(@id, @pid)", con);
cmdd.CommandType = System.Data.CommandType.Text;
cmdd.Parameters.AddWithValue("@id", row.Cells[1].Text);
cmdd.Parameters.AddWithValue("@pid", txtbid.Text);
cmdd.ExecuteNonQuery();
}
}
protected void btnAdd_Click(object sender, EventArgs e)
{
DataSet ds = (DataSet)Session["data"];
DataRow dr = ds.Tables[0].NewRow();
dr[0] = DropDownList1.Text.Trim();
dr[1] = DropDownList1.SelectedItem;
//dr[2] = txtId.Text.Trim();
ds.Tables[0].Rows.Add(dr);
GridView1.DataSource = ds;
GridView1.DataBind();
}
Now, I am trying to remove checked rows on my gridview with this code:
protected void btnRemove_Click(object sender, EventArgs e)
{
ArrayList del = new ArrayList();
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
CheckBox chkDelete = (CheckBox)row.Cells[0].FindControl("CheckBox1");
if (chkDelete != null)
{
if (chkDelete.Checked)
{
string id = row.Cells[1].Text;
del.Add(productId);
}
}
}
}
GridView1.DataBind();
}
