How to add default parameters to Quick Search through customization ? I used the code below but it return some error. I replace the “new DataTable()” with "defaultConditions ".

            DataTable defaultConditions = new DataTable();
            defaultConditions.Columns.Add("FieldName", typeof(string));
            defaultConditions.Columns.Add("Operator", typeof(string));
            defaultConditions.Columns.Add("Value", typeof(string));

            DataRow conditionRow = defaultConditions.NewRow();
            conditionRow["FieldName"] = "PartClass.ClassID";  
            conditionRow["Operator"] = "=";        
            conditionRow["Value"] = "001";      
            defaultConditions.Rows.Add(conditionRow);

I use a quick search with default parameters on the sales order entry. In my case I need to pass in CustID to the search to filter by order history. I don’t have the original source handy but it was from elsewhere on this forum and I’ve adjusted it to work for me.

sender = oTrans.EpiBaseForm;
QuickSearchAdapter _qdA = new QuickSearchAdapter(oTrans);
_qdA.BOConnect();
_qdA.GetByID("","CustXRefSearch");
QuickSearchDataSet qsds = _qdA.QuickSearchData;

// Loop through all criteria to find what I want.  Only Constant type seem to work with passed in values
foreach(QuickSearchDataSet.QuickSearchCriteriaRow r in qsds.QuickSearchCriteria) {
    if(r.FieldName.Equals("CustID") && r.CriteriaType.Equals("Constant")) {
        r.CriteriaValue = edvH.CurrentDataRow["CustomerCustID"].ToString();
        break;
    }
}
  
using(QuickSearchPanel panel = _qdA.GetQuickSearchPanel(oTrans.EpiBaseForm)) {
	if(panel !=null) {
		using(QuickSearchForm form = new QuickSearchForm(_qdA)) {
			form.LastQS = "CustXRefSearch";
			System.Reflection.MethodInfo mi = form.GetType().GetMethod("addQuickSearchPanel",System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
			mi.Invoke(form, new object[]{panel});

			SearchOptions options = SearchOptions.CreateSearchForm(DataSetMode.ListDataSet);
			options.Sender = sender;

			options.SelectMode = SelectMode.SingleSelect;
			form.ShowDialog(new Ice.Lib.Searches.EpiSearchEngine((EpiBaseAdapter)_qdA),options);
			System.Reflection.FieldInfo fi = form.GetType().GetField("selectObject", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
			object ret = fi.GetValue(form);
			if(ret!=null) {
				// Do something with ret value  
			}
		}
	}
}
