Get item name using item id (using active mathod and display mathod)

Today i am using active mathod to store item name in database table using display mathod.

Step1 . create table and take 2 string control one for itemid and second form itemname

Step 2. Write mathod in table mathod dispaly mathod name itemname

display itemname itemname()

{

inventtable inventtable;

;

return inventtable::find(this.ItemId).ItemName;

}

Step3. Now create form take both control and in itemid control datasource new table and datamathod name this display mathod itemname().

By this now when you select itemid , you will select itemname. But by this you will not see itemname in table.

For that

Step4. Form -> datasource mathod -> overwrite active mathod and write this code.

public int active()

{

   int ret;

   ret = super();

   

   RackInqueryTable.itemname = rackinquerytable.itemname();

   return ret;

}

Now you will see change in form and table too.

Thanks
