Question

I have a group checkbook list which i want to preselect from the database table. I amusing following code to for the selection of this but it is not working

Data in table is store in following format
example:-

1,2,
1,5,7,
1,2,3,4,

HTML

<asp:checkboxlist id="chkBoxDaysList" runat="server">
 <asp:listitem  runat="server" value="1"  Text="Sunday" />
 <asp:listitem  runat="server" value="2" Text="Monday" />
 <asp:listitem  runat="server" value="3" Text="Tuesday" />
 <asp:listitem  runat="server" value="4" Text="Wednesday" />
 <asp:listitem  runat="server" value="5" Text="Thrusday" />
 <asp:listitem  runat="server" value="6" Text="Friday" />
 <asp:listitem  runat="server" value="7" Text="Saturday" />
</asp:checkboxlist>

C# Code to preselect checkbox based on data saved previously

public void getSelectedDays()
{
IDataReader dr;

String strSqlDays = "SELECT * FROM EventCalender WHERE rowID = 6";
DataSet ds = new DataSet();
ds = DataProvider.Connect_Select(strSqlDays);
dr = ds.Tables[0].CreateDataReader();

string[] s = new string[50];
while (dr.Read())
{
    s = dr["EventDays"].ToString().Split(',');

}
int length = s.Length;
for (int i = 0; i <= s.Length - 1; i++)
{
    string cntry = s[i];
    for (int j = 0; j <= chkBoxDaysList.Items.Count - 1; j++)
    {
        if (chkBoxDaysList.Items[j].Text == s[i])
        {
            chkBoxDaysList.Items[j].Selected = true;
            break;
        }
    }
}

}

Right now code doesn’t generate any error but doesn’t select any checkbox also

Answer 1

You are checking text of checkbox with value from DB. Please check value of the checkboxlist with value from DB record.Corrected code is shown below–>

 if (chkBoxDaysList.Items[j].Value == s[i])
        {
            chkBoxDaysList.Items[j].Selected = true;
            break;
        }
