X++ | d365FO - Create a list of table name lookup

 
This is very similar to X++ | d365FO - Create a lookup with a table fields list. Just show another example which looks quite simpler.

Scenario / expected result
We have a string control on a form, then we'd like to have a lookup which shows all of table name from AOT.
 














Solution
The overview processes are:
 
  1. Create a temp table with metadata-populate method
  2. Add a lookup method to the table that will be a form's data source
  3. Add a lookup method on the form's control
 
1. Create a temp table with metadata-populate method
 
Create 'aaaTableNameListTemp' table. Set it as InMemory table. Add a string 'TableName' field (extends from IdentifierName or else you want).
 



Create 'populate' method 
 using Microsoft.Dynamics.AX.Metadata.MetaModel;  
 public class aaaTableNameListTemp extends common  
 {  
   public static aaaTableNameListTemp populate()  
   {  
     aaaTableNameListTemp table;  
     var tables = Microsoft.Dynamics.Ax.Xpp.MetadataSupport::TableNames();  
     while (tables.MoveNext())  
     {  
       table.clear();  
       table.initValue();  
       table.TableName = tables.Current;  
       table.insert();  
     }  
     return table;  
   }  
 }
 
2. Add a lookup method to the table that will be a form's data source

For example, if our table is 'aaaTable' table. Add 'lookupTableName' method on that table. 
   public void lookupTableName(FormStringControl _control)  
   {  
     SysTableLookup    lookup;  
     QueryBuildDataSource qbds;  
     Query q = new Query();  
     qbds = q.addDataSource(tableNum(aaaTableNameListTemp));  
     qbds.addSortField(fieldNum(aaaTableNameListTemp, TableName), SortOrder::Ascending);  
     lookup = SysTableLookup::newParameters(tableNum(aaaTableNameListTemp),  
              _control,  
              true);  
     lookup.addLookupField(fieldnum(aaaTableNameListTemp, TableName), true);  
     lookup.parmQuery(q);  
     lookup.parmTmpBuffer(aaaTableNameListTemp::populate());  
     lookup.performFormLookup();  
   }
3. Add a lookup method on the form's control

On your desired control, override 'lookup' method and put the below code.
 

 








  
   [Control("String")]  
   class Grid_FormName  
   {  
     public void lookup()  
     {  
       aaaTable.lookupFormName(this);  
     }  
   }

 

 

............................................

 

 [Control("String")]
    class DGS_EditWorkTemplateSettings_WorkTemplateTable
    {
        /// <summary>
        ///
        /// </summary>
        public void lookup()
        {
            SysTableLookup    lookup;
            QueryBuildDataSource qbds;
            Query q = new Query();
            qbds = q.addDataSource(tableNum(DGS_TableNameListTmp));
            qbds.addSortField(fieldNum(DGS_TableNameListTmp, TableName), SortOrder::Ascending);
            lookup = SysTableLookup::newParameters(tableNum(DGS_TableNameListTmp),
              this,
              true);
            lookup.addLookupField(fieldnum(DGS_TableNameListTmp, TableName), true);
            lookup.parmQuery(q);
            lookup.parmTmpBuffer(DGS_TableNameListTmp::populate());
            lookup.performFormLookup();
        }

    }

    [Control("String")]
    class DGS_EditWorkTemplateSettings_WorkTemplateField
    {
        /// <summary>
        ///
        /// </summary>
        public void lookup()
        {
            SysTableFieldLookup tableFieldLookup; // function for lookup field
            TmpSysTableField tmpSysTableField;  // to catch selected lookup value
            str tableName = DGS_EditWorkTemplateSettings_WorkTemplateTable.valueStr();

            Query query = new Query();
            ;
            query.addDataSource(Global::tableName2Id(tableName));
            tableFieldLookup = new SysTableFieldLookup(query);
            tmpSysTableField.DictTableId = (Global::tableName2Id(tableName));
            tableFieldLookup.performLookupField(this, tmpSysTableField); // lookup display label description
        }

    }

 

 

// 在Query中尋找有多少Table:

    public static DGS_TableNameListTmp populateByQuery(str QueryName)
    {
        DGS_TableNameListTmp table;
        Query q;
        QueryRun queryRun;
        int i,j,dsCount,rangeCount;
        QueryBuildDataSource ds;

        queryRun = new QueryRun(QueryName);
        q = queryRun.query();

        dsCount   = q.dataSourceCount();
        for (i = 1; i <= dsCount; i++)
        {
            ds = q.dataSourceNo(i);           
            table.TableName = tableId2Name(ds.table());
            table.insert();
        }      
        return table;
    }
