怎么把已有数据库绑定到gridview中，最好给出代码
如题
[解决办法]
string connStr =ConfigurationSettings.AppSettings[ "ConnString1 "].ToString();
Session[ "constr "] = connStr;
string SqlStr = "SELECT * FROM 表 ";
DataSet ds = new DataSet();
try
{
SqlConnection conn = new SqlConnection(connStr);
if (conn.State.ToString() == "Closed ") conn.Open();
SqlDataAdapter da = new SqlDataAdapter(SqlStr, conn);
da.Fill(ds, "test01 ");
if (conn.State.ToString() == "Open ") conn.Close();
GridView1.DataSource = ds.Tables[0].DefaultView;
GridView1.DataBind();
}
catch (Exception ex)
{
//throw ex;
Response.Write( "数据库错误，错误原因： " + ex.Message);
Response.End();
}
[解决办法]
DataTable dt=..//你自己获取数据的方法，也可以是dataset等
gridview1.DataSource=dt;
gridview.DataBind();
[解决办法]
string str1= "select * from table ";
try
{
using(con = new SqlConnection(System.Configuration.ConfigurationSettings.AppSettings[ "DSN "]))
{
DataSet ds = new DataSet();
adapter = new SqlDataAdapter(str1,con);
adapter.SelectCommand.Parameters.Add( "@Id ",Request.QueryString[ "Id "].ToString());
adapter.Fill(ds);
DataColumn dc = new DataColumn( "Des ",System.Type.GetType( "System.String "));
this.gridview1.DataSource = ds.Tables[0].DefaultView;
this.gridview1.DataBind();
}
}
catch
{}
