I have 1 Dropdownlist and 3 Textboxes and I want to add data from textboxes and after a button click they will be added to GridView
<asp:DropdownList ID="ddlClassification" runat="server" >
<asp:ListItem></asp:ListItem>
<asp:ListItem>Sample 1</asp:ListItem>
<asp:ListItem>Sample 2</asp:ListItem>
<asp:ListItem>Sample 3</asp:ListItem>
</asp:DropdownList>
<asp:TextBox ID="tbCost" runat="server" Width="100" ></asp:TextBox>
<asp:TextBox ID="tbAccumulate" runat="server" Width="100" ></asp:TextBox>
<asp:TextBox ID="tbNRV" runat="server" Width="100" ></asp:TextBox>
<asp:Button ID="btnAdd" runat="server" Text="ADD" onclick="btnAdd_Click" />
and this is What I have in code behind
public partial class SetUP : System.Web.UI.Page
{
DataRow dr;
DataTable dt = new DataTable();
protected void Page_Load(object sender, EventArgs e)
{
dt.Columns.Add("Classification");
dt.Columns.Add("Cost");
dt.Columns.Add("Accumulate");
dt.Columns.Add("NRV");
}
protected void btnAdd_Click(object sender, EventArgs e)
{
dr = dt.NewRow();
dr["Classification"] = ddlClassification.Text;
dr["Cost"] = tbCost.Text;
dr["Accumulate"] = tbAccumulate.Text;
dr["NRV"] = tbNRV.Text;
dt.Rows.Add(dr);
GridView1.DataSource = dt;
GridView1.DataBind();
