Add a User Control to a Form

When you add a user control to a form, you should use the Sub-View control and set the VirtualPath property to the user control ASCX file.

Procedure

1. Create a user control.
2. Sign the user control project.
3. Set the Inherits property of the user control to the full class name.
   Inherits="WebApplication1.WebUserControl1 ,WebApplication1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=4b06ea5bb276e861"
4. Put the user's control assembly in the GAC.
5. Put the ASCX file in the Cora SeQuence shared resources folder.
6. On the form, add a Sub-View control, and in the markup, set the VirtualPath property.

Get the Cora SeQuence Form Control (hosting the user control)

 private FormControl GetFormControl()
        {
            Control control = this.Parent;
            FormControl sequenceForm = null;
            while (control != null)
            {
                sequenceForm = control as FormControl;
                if (sequenceForm != null)
                {
                    break;
                }
                control = control.TemplateControl;
                //the TemplateControl property for a user control returns itself or null
                if (control != null)
                {
                    control = control.Parent;
                }
            }
            return sequenceForm;
        }

Add the Save Data Function

private void SaveData(List<string> values)
        {
            FormControl sequenceForm = GetFormControl();
            if (sequenceForm != null)
            {
                var viewModel = this.GetFormUIViewModel();
                if (viewModel != null)
                {
                    DataModel dataModel = ((IDataModelAccessor)sequenceForm).DataModel;
                    DataContext ctx = viewModel.DataContextManager.GetDataContext(dataModel);
                    IDataTable logTable = ctx.GetDataTable("TableQueryName");
                    IDataRow logRow;
                    foreach (string s in values)
                    {
                        logRow = logTable.CreateRow();
                        //add the rest of the fields here
                        //logRow.SetField("[field name]", [value]);
                        logRow.SetField("myString", s);
                        logTable.InsertOnSubmit(logRow);
                    }
                    try
                    {
                        ctx.SubmitChanges();
                    }
                    catch (Exception ex)
                    {
                        DiagnosticUtility.EventLog.LogError("Error submiting the data.\n" + ex.ToString());
                        throw;
                    }
                }
            }
        }

Add the Event that Triggers the Save Method

 protected void Button1_Click(object sender, EventArgs e)
        {
            List<string> l = new List<string>();
            l.Add("a");
            l.Add("b");
            SaveData(l);
        }
