hi how can i bind field from table to label?

推荐答案

试试这个.. :)

try this..:)

//Put this code in Combobox selected index change event

      DataTable dt = new DataTable();
      using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionName"].ConnectionString))
      {
          using (SqlCommand cmd = new SqlCommand("select Mark from TableName where Name="+ ComboBox.SelectedValue, con))
          {
              con.Open();
              SqlDataAdapter da = new SqlDataAdapter(cmd);
              da.Fill(dt);

              lblMark.Text = Convert.ToString(dt.Rows["Mark"]);

              con.Close();
              con.Dispose();
              cmd.Dispose();
          }
      }

它的工作对我来说，但这个标签在我的Gridview里面



希望它也为你工作



< asp：label id =Name1runat =servertext =< ;％＃DataBinder.Eval（Container.DataItem，column_name）％& gt;=xmlns：asp =＃unknown>

Its work for me but this label was inside my Gridview

Hope its work for you also

<asp:label id="Name1" runat="server" text="<%#DataBinder.Eval(Container.DataItem, " column_name")%&gt;"="" xmlns:asp="#unknown">
