Delete CheckBox Checked Selected Items in ListView ASP.Net

Hi @ Sangi,

I have made a small snippet for you.

Please try it.

HTML

 <div>
        <asp:ListView ID="lvUsers" runat="server">
            <ItemTemplate>
                <asp:CheckBox ID="chkCustomer" runat="server" />
                <asp:Label ID="lblCustomerId" runat="server" Text='<%#Eval("CustomerId") %>'></asp:Label>
                <asp:Label ID="lblCustomerName" runat="server" Text='<%#Eval("CustomerName") %>'></asp:Label>
                <br />
            </ItemTemplate>
        </asp:ListView>
        <asp:Button ID="btnDelete" runat="server" Text="Delete" OnClick="Delete" />
    </div>

C# Code:-

        SqlConnection con;
        SqlCommand cmd;
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)
            {
                con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConString"].ConnectionString);
                cmd = new SqlCommand("SELECT CustomerId, CustomerName FROM Customers", con);
                SqlDataAdapter da = new SqlDataAdapter(cmd);
                DataTable dt = new DataTable();
                da.Fill(dt);
                this.lvUsers.DataSource = dt;
                this.lvUsers.DataBind();

            }
        }

        protected void Delete(object sender, EventArgs e)
        {
            foreach (ListViewDataItem item in this.lvUsers.Items)
            {
                if (item.ItemType == ListViewItemType.DataItem)
                {
                    CheckBox chkUser = item.FindControl("chkCustomer") as CheckBox;
                    if (chkUser.Checked)
                    {
                        int customerId = int.Parse((item.FindControl("lblCustomerId") as Label).Text.Trim());
                        con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConString"].ConnectionString);
                        cmd = new SqlCommand("DELETE FROM Customers WHERE CustomerId=@Id", con);
                        cmd.Parameters.AddWithValue("@Id", customerId);
                        con.Open();
                        cmd.ExecuteNonQuery();
                        con.Close();
                    }
                }
            }

            Response.Redirect(Request.Url.AbsolutePath);
        }
