[nahla]

dear all

have a good day

i've a radschadualr in which students segister there schadual.

this schadual consists of substances each one is (leacture-tutorial-lab).

what i need is forcing the student to choose these sub categories (leacture-tutorial-lab) before leaving to choose new subject. and if he tries an error msg popup saying that "you should choose all substance groop- please complete your choice".

here is the code i wrote but it does't work.

　

if

(this.treeView.SelectedNode == null)

return;

if (this.treeView.SelectedNode.Value != "m")

return;

string s = this.treeView.SelectedNode.Text;

string corsnode = this.treeView.SelectedNode.ParentNode.Text;

string cors_id = corsnode.Substring(0, corsnode.IndexOf('-') - 1).Trim();

string stu_id = Session["test"].ToString();

OracleConnection conn = new OracleConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

try
 {
 conn.Open();
 OracleCommand cmd = new OracleCommand("COMPLETE_GROUP_TYPE");
cmd.CommandType =CommandType.StoredProcedure;
 cmd.Connection = conn;
 cmd.Parameters.Add("COURSEID", OracleType.Char).Value = cors_id.ToString();
cmd.Parameters.Add("STUDENTID", OracleType.Char).Value = stu_id.ToString();
 cmd.ExecuteNonQuery();
 }
 catch (Exception ex)
 {
 Label2.Text ="ERROR."+ ex.Message;
 }
 finally
 {
 conn.Close();
 }

Hello Nahla,

It is not very clear which event you are trying to handle and what exactly you are trying to validate. If I understand you correctly, you may have a look at the Advanced Template demo in the AdvancedForm.aspx file to see how the validation issue is handled there.

      lec.102 sun(9:am-10.30am).
      tut.105 sat(11am-12.30 pm).
      lab.200 mon(9am-10.30am).
-dem250
      lec205 tus(9am-11am).

what i need is to force the student to choose all appointements in corse cs510.
b4 leaving to choose in corse dem250.

Hello Nahla,

It is difficult me to understand what exactly seems to be the issue.
Would you please try to isolate the problem in a sample project and send it to us via support ticket so that we can be more helpful.
