Setting a field value or values removes previous selection

I have setup the QlikView OCX to work in my C# winforms app. I have gathered all possible field values for the specific fields that I am looking to target. I have created selectors that hold that data in .NET controls. The user would make selections within the .NET controls and click a button to set the field values.

I can easily set a field value for one of the fields. For example I am having no problem setting the date when that is the only option selected. However, if the user then makes a "company" selection along with the date selection, only the company selection is set. I can see in my current selections object that the date was initially set, very briefly, then when the company gets set it overrides the previous date selection. All I am left with is just the company selection, no date.

Here is the code I have:

private void SetValues() { Field dateField = qvDoc.GetField("Date"); dateField.Clear(); IArrayOfFieldValue selectedDateFields = tradeDateField.GetNoValues(); selectedDateFields.Add(); selectedDateFields[0].Number = Convert.ToDouble(qvDoc.Evalueate("=num('" + (DateTime)ddlDate.EditValue _ "')")); selectedDateFields[0].IsNumeric = true; dateField.SelectValues(selectedDateFields); Field companyField = qvDoc.GetField("Company"); companyField.Clear(); IArrayOfFieldValue selectedCompanyFields = companyField.GetNoValues(); for (int i = 0; i < selectedCompanies.Count; i++) { selectedCompanyFields.Add(); selectedCompanyFields[i].Text = selectedCompanies[i]; } companyField.SelectValues(selectedCompanyFields);

}

When running that method I would expect to see my current selections set with a date and company. Only the company is being set. What am I missing? Why does this remove my previous selection?
