以下は私のコードです...
protected void Button3_Click(object sender、EventArgs e){fillgrid();
for (int i = 0; i < GridView1.Rows.Count; i++)
{
Label lblteachername = (Label)GridView1.Rows[i].FindControl("lblgridteachername");
CheckBox status = (CheckBox)GridView1.Rows[i].FindControl("chkgridstatus");
if (status.Checked == true)
{
string q = "insert into teacher (status) values('"+dayList[i].Date+"') where schid='"+dayList[i].SchId+"'";
}
}
}
問題は、girdviewのチェックボックスをオンにするかどうかに関係なく、if (status.Checked==true)
常に戻ることです。false
public void fillgrid()
{
string q = "select * from teacher where teachername='" + drpteachername.SelectedItem.ToString() + "' and ('2013-03-01' between date and todate) and '2013-03-31' between date and todate";
dt = dbo.Getdt(q);
//NOTE- if you bind gridview with dt, gridview will automatically generate no. of rows equal to the no. of rows returned to dt through the sql query from database.
abc();
DataTable dt1 = new DataTable();
for (int i = 0; i < dayList.Count; i++)
{
DataRow dr = dt1.NewRow();
dt1.Rows.Add(dr);
}
GridView1.DataSource = dt1;
GridView1.DataBind();
string teachername = drpteachername.SelectedItem.ToString();
string month = drpmonth.SelectedItem.ToString();
string strclass = drpclass1.SelectedItem.ToString();
string section = drpsection1.SelectedItem.ToString();
//string time=drpstarttime1.SelectedItem.ToString();
for (int i = 0; i < dayList.Count; i++)
{
Label lbldate = (Label)GridView1.Rows[i].FindControl("lblgriddate");
string fullstring = Convert.ToString(dayList[i].Date);
lbldate.Text = fullstring.Substring(0, 9);
//string q1 = "select starttime,endtime from teacher where teachername='"+drpteachername+"', and '"+fullstring+"' between date and todate";
//dt = dbo.Getdt(q1);
//int count=dt.Rows.Count;
Label lblteachername = (Label)GridView1.Rows[i].FindControl("lblgridteachername");
lblteachername.Text = teachername;
Label lblclass = (Label)GridView1.Rows[i].FindControl("lblgridclass");
lblclass.Text = dayList[i].Class;
Label lblsection = (Label)GridView1.Rows[i].FindControl("lblgridsection");
lblsection.Text = dayList[i].Section;
Label lbltime = (Label)GridView1.Rows[i].FindControl("lblgridtime");
lbltime.Text = dayList[i].StartTime.Substring(0, 5) + "-" + dayList[i].EndTime.Substring(0, 5);

abc()メソッドはリストを埋めるだけです。文脈がより明確になったことを願っています。
