推荐答案

hi，



猜你可以在代码隐藏中调用OnTextChanged事件并尝试从那里访问gridview。
代码下面的
可能会有所帮助：

guess u can call OnTextChanged event in the codebehind and try to access the gridview from there.
below code might help:

<asp:textbox id="TextBox1" runat="server" autopostback="true" ontextchanged="text" xmlns:asp="#unknown"></asp:textbox>

数据访问层：

data access layer:

public DataTable populategridview(int id)
  {
      SqlDataAdapter da = new SqlDataAdapter("select empname from development.dbo.employee where empid='" + id + "'", xconn);
      DataTable dt = new DataTable();
      da.Fill(dt);
      return dt;
  }

Codebehind：

Codebehind:

protected void text(object sender, EventArgs e)
{
    DAL obj2 = new DAL();
    int id = Convert.ToInt32(TextBox1.Text);
    DataTable dtnew = obj2.populategridview(id);
    grdview.DataSource = dtnew;
    grdview.DataBind();

}

尝试做上面的事情..猜它应该有效..还没试过它...... :)
