Custom lookup on EP

21 Sep

To provide an ASP.Net text box to work as AX lookup field, need to follow following steps
1-Creae a new text box in page (Out of AXForm)
2-Add new ax lookup control from tool box
3-Set target control as added text box by using Lookup control’s target properly
4-If you want to show filtered data on the lookup then chose lookup types as CustomDataSet
5-To define lookup dataset use lookupControl’s Lookup event and set lookupDataSet by using following pattern code

protected void LookupFieldName_Lookup(object sender, AxLookupEventArgs e)
{
//Getcurrent user to filter record based on current user
String usr = WindowsIdentity.GetCurrent().Name;
int pos = usr.IndexOf(‘\\’);
usr = pos != -1 ? usr.Substring(pos + 1) : usr;
AxLookup lookup = (AxLookup)sender;

// Create the lookup data set. The respective table will be used.
Proxy.SysDataSetBuilder sysDataSetBuilder;
sysDataSetBuilder = Proxy.SysDataSetBuilder.constructLookupDataSet(AxSession.AxaptaAdapter,TableMetadata.TableNum(AxSession, “TableName”));

// Set the generated data set as the lookup data set.
lookup.LookupDataSet = new DataSet(AxSession, sysDataSetBuilder.toDataSet());
using (Proxy.Query query = lookup.LookupDataSet.DataSetViews[0].MasterDataSource.query())
{
query.dataSourceNo(1).addRange(TableArrayFieldMetadata.FieldNum(this.AxSession, “TableName”, “FieldName”)).value = “ValueInStringFormat”
//Example String.Format(“{0:dd/MM/yyyy}..{1}”, System.DateTime.Today, DateTime.MaxValue.ToShortDateString());

}

// Specify the fields for the lookup.
lookup.Fields.Add(AxBoundFieldFactory.Create(AxSession, lookup.LookupDataSetViewMetadata.ViewFields[“Field1”]));
lookup.Fields.Add(AxBoundFieldFactory.Create(AxSession, lookup.LookupDataSetViewMetadata.ViewFields[“Field2”]));
lookup.Fields.Add(AxBoundFieldFactory.Create(AxSession, lookup.LookupDataSetViewMetadata.ViewFields[“Field3”]));
lookup.Fields.Add(AxBoundFieldFactory.Create(AxSession, lookup.LookupDataSetViewMetadata.ViewFields[“Field4”]));
// Specify the select field for the lookup.
lookup.SelectField = “Index/LookupFieldName”;
