我有1个Dropdownlist和3个Textboxes,我想从文本框中添加数据,点击按钮后会将它们添加到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" />
这就是我在代码背后的内容
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();
}
我已经完成了一次,但现在我在GridView1.DataBind();
上收到错误有人可以帮我解决问题

当您添加列时,请执行此操作
dt.Columns.Add(new DataColumn("Classification", typeof(string)));
