dt.Columns.Add(col);
col = new DataColumn("col3");
dt.Columns.Add(col);
col = new DataColumn("col4");
dt.Columns.Add(col);
dr ["col1"] = this.drpdwnmedicine_name.SelectedValue;

dr ["col3"] = this.dosage.Value;

推荐答案

尝试查找通过以下方式.

try to find out in the following way.

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">

      <Columns>

          <asp:BoundField DataField="CompanyName"  HeaderText="Company"/>

          <asp:BoundField DataField="ContactName" HeaderText="Name"/>

          <asp:BoundField DataField="ContactTitle" HeaderText="Title"/>

          <asp:BoundField DataField="Address" HeaderText="Address"/>

      </Columns>

      </asp:GridView>
