禁用该复选框后，不应进行更新

我有两个页面，一个是管理员，另一个是教师。 管理员根据教师分配科目。 学院只想选择所需时间。 我的问题是我不想对禁用的复选框执行更新查询。 我已经尝试了下面的代码，但它也正在更新为禁用复选框。

using (SqlConnection con2 = new SqlConnection(ConfigurationManager.ConnectionStrings ["ConnectionString"].ConnectionString)) { foreach (GridViewRow r in Gv1.Rows){ if (((( (((CheckBox)(Gv1.Rows[r.RowIndex].FindControl("chkHour1"))).Checked == true || ((CheckBox)(Gv1.Rows[r.RowIndex].FindControl("chkHour1"))).Checked == false) || (((CheckBox)(Gv1.Rows[r.RowIndex].FindControl("chkHour2"))).Checked == true || ((CheckBox)(Gv1.Rows[r.RowIndex].FindControl("chkHour2"))).Checked == false) || (((CheckBox)(Gv1.Rows[r.RowIndex].FindControl("chkHour3"))).Checked == true || ((CheckBox)(Gv1.Rows[r.RowIndex].FindControl("chkHour3"))).Checked == false) || (((CheckBox)(Gv1.Rows[r.RowIndex].FindControl("chkHour4"))).Checked == true || ((CheckBox)(Gv1.Rows[r.RowIndex].FindControl("chkHour4"))).Checked == false) || (((CheckBox)(Gv1.Rows[r.RowIndex].FindControl("chkHour5"))).Checked == true || ((CheckBox)(Gv1.Rows[r.RowIndex].FindControl("chkHour5"))).Checked == false) )))) { SqlCommand comm; CheckBox aa; bool hour1 = (r.FindControl("chkHour1") as CheckBox).Checked; bool hour2 = (r.FindControl("chkHour2") as CheckBox).Checked; bool hour3 = (r.FindControl("chkHour3") as CheckBox).Checked; bool hour4 = (r.FindControl("chkHour4") as CheckBox).Checked; bool hour5 = (r.FindControl("chkHour5") as CheckBox).Checked; string subject1 = ddlsubj.SelectedValue; string subject2 = ddlsubj.SelectedValue; string subject3 = ddlsubj.SelectedValue; string subject4 = ddlsubj.SelectedValue; string subject5 = ddlsubj.SelectedValue; string datedif = r.Cells[0].Text; aa=(CheckBox)sender; con2.Open(); comm = new SqlCommand(); comm.Connection = con2; comm.CommandType = CommandType.Text; if (aa.Enabled==false) { comm = new SqlCommand("UPDATE test SET aa=false when subject1=CASE WHEN (@hour1)= 'false' THEN NULL ELSE @subject1 END, subject2=CASE WHEN (@hour2)= 'false' THEN NULL ELSE @subject2 END, subject3=CASE WHEN (@hour3)= 'false' THEN NULL ELSE @subject3 END, subject4=CASE WHEN (@hour4)= 'false' THEN NULL ELSE @subject4 END, subject5=CASE WHEN (@hour5)='false' THEN NULL ELSE @subject5 END, hour1 = CASE WHEN (@hour1)= 'false' THEN 'false' ELSE 'true' END, hour2 = CASE WHEN (@hour2)= 'false' THEN 'false' ELSE 'true' END, hour3 = CASE WHEN (@hour3)= 'false' THEN 'false' ELSE 'true' END , hour4 = CASE WHEN (@hour4)= 'false' THEN 'false' ELSE 'true' END , hour5 = CASE WHEN (@hour5)= 'false' THEN 'false' ELSE 'true' END where datedif=@datedif", con2); } else { comm = new SqlCommand("update test set aa=true when subject1=CASE WHEN (@hour1)= 'false' THEN NULL ELSE @subject1 END, subject2=CASE WHEN (@hour2)= 'false' THEN NULL ELSE @subject2 END, subject3=CASE WHEN (@hour3)= 'false' THEN NULL ELSE @subject3 END, subject4=CASE WHEN (@hour4)= 'false' THEN NULL ELSE @subject4 END, subject5=CASE WHEN (@hour5)='false' THEN NULL ELSE @subject5 END, hour1 = CASE WHEN (@hour1)= 'false' THEN 'false' ELSE 'true' END, hour2 = CASE WHEN (@hour2)= 'false' THEN 'false' ELSE 'true' END, hour3 = CASE WHEN (@hour3)= 'false' THEN 'false' ELSE 'true' END , hour4 = CASE WHEN (@hour4)= 'false' THEN 'false' ELSE 'true' END , hour5 = CASE WHEN (@hour5)= 'false' THEN 'false' ELSE 'true' END where datedif=@datedif", con2); } comm.Parameters.AddWithValue("@subject1",subject1); comm.Parameters.AddWithValue("@subject2", subject2); comm.Parameters.AddWithValue("@subject3", subject3); comm.Parameters.AddWithValue("@subject4", subject4); comm.Parameters.AddWithValue("@subject5", subject5); comm.Parameters.AddWithValue("@hour1", hour1); comm.Parameters.AddWithValue("@datedif", datedif); comm.Parameters.AddWithValue("@hour2", hour2); comm.Parameters.AddWithValue("@hour3", hour3); comm.Parameters.AddWithValue("@hour4", hour4); comm.Parameters.AddWithValue("@hour5", hour5); comm.ExecuteNonQuery(); con2.Close(); } } } 

Answer 1

您可能希望首先删除IF语句，因为它不需要。 正如其他人所说的那样，正在检查两个真正的OR（||）假，它总是正确的。

第二，看不到你检查的任何地方.Enabled == False这可能适合你所看到的。

Answer 2

根据您的代码，如果禁用复选框，则执行一个查询，如果启用了复选框，则执行另一个查询

 if (aa.Enabled==false) { } else{ } 

如果您不想在禁用的复选框上执行，请删除下面的部分

 if (aa.Enabled==false) { }
