當while循環重複迭代時,我已經有一個問題,已經綁定的是由新記錄替換,但我想通過while循環的迭代來綁定所有數據。Gridview數據綁定
我是一個新的我不知道它是如何可能的。
while (i >= 0)
{
if (i != 0)
{
group_idd = group_ids[--i];
}
SqlConnection connection3 = new SqlConnection(ConfigurationManager.ConnectionStrings["Connection_String"].ConnectionString);
using (connection3)
{
using (SqlCommand cmdd = new SqlCommand())
{
cmdd.CommandText = "SELECT [news_category],[id] FROM [news_profile] WHERE [user_id]='" + user_id + "' AND [group_id]='" + group_idd + "' AND [profile_id] IS NOT NULL";
cmdd.Connection = connection3;
connection3.Open();
GridView1.DataSource = cmdd.ExecuteReader();
GridView1.DataBind();
connection3.Close();
}
}
if (i == 0)
{
--i;
}
}
