在我的 asp.net 项目中,如何在单击按钮后立即刷新我的 gridview。我的按钮有更新代码。这是代码;
protected void Button3_Click(object sender, EventArgs e)
{
string strSQL = "UPDATE [bilgiler3] SET [HAM_FM] = ISNULL(MON,0)+ISNULL(TUE,0)+ISNULL(WED,0)+ISNULL(THU,0)+ISNULL(FRI,0)+ISNULL(SAT,0)+ISNULL(SUN,0) WHERE [DATE] BETWEEN @DATE1 AND @DATE2 AND WORK_TYPE='OUT'";
string connStr = WebConfigurationManager.ConnectionStrings["asgdb01ConnectionString"].ConnectionString;
using (SqlConnection conn = new SqlConnection(connStr))
{
using (SqlCommand comm = new SqlCommand())
{
comm.Connection = conn;
comm.CommandText = strSQL;
comm.CommandType = CommandType.Text;
comm.Parameters.AddWithValue("@DATE1", Convert.ToDateTime(TextBox1.Text));
comm.Parameters.AddWithValue("@DATE2", Convert.ToDateTime(TextBox2.Text));
try
{
conn.Open();
int i = comm.ExecuteNonQuery();
conn.Close();
if (i > 0)
{
Response.Write(" SUCCESS ");
}
else
{
Response.Write(" ERROR ! ");
}
}
catch (SqlException ex)
{
Response.Write(ex.ToString());
}
}
}
}
你可能会说“你需要绑定你的gridview的数据”,但我不明白这个方法。你能帮帮我吗?
非常感谢您。
