Hi Experts,

I am facing difficulty to hide values on control Deliver_DlvMode in SalesAgreementGenerateReleaseorder form because there datasources SalesCreateReleaseOrderTableTmp and SalesCreateReleaseOrderLineTmp is temp table and DlvMode field is from these tables.

I was trying to OnQueryExecuting to just show "X-Factory" from Deliver_DlvMode control by eventhandler as below:

   [FormDataSourceEventHandler(formDataSourceStr(SalesAgreementGenerateReleaseOrder, SalesCreateReleaseOrderTableTmp), FormDataSourceEventType::QueryExecuting)]
    public static void SalesCreateReleaseOrderTableTmp_OnQueryExecuting(FormDataSource sender, FormDataSourceEventArgs e)
    {
       
        
        sender.query().dataSourceName(sender.name()).addRange(fieldnum(SalesCreateReleaseOrderTableTmp,DlvMode)).value("X-Factory");
    }

After Event Handler build, all fields grey out.

I need help how to achieve this.

Thanks,

Faiz

If I understand correctly, you want to limit the delivery modes that are available when creating a release order. You have to override the lookup of the delivery mode control. In your example, your are filtering the datasource of the form, that's why you don't see any data anymore.

Below is a simple working example (last time I checked) of how to override the lookup of the item field of a sales order. There are many examples online on how to do this.

public class SalesTableEventHandler { [FormDataSourceEventHandler(formDataSourceStr(SalesTable, SalesLine), FormDataSourceEventType::Initialized)] public static void SalesLine_OnInitialized(FormDataSource _sender, FormDataSourceEventArgs _e) { var overrides = SalesTableFormExtensionOverrides::construct(); _sender.object(fieldNum(SalesLine, ItemId)).registerOverrideMethod(methodStr(FormDataObject, lookup), methodStr(SalesTableFormExtensionOverrides, ItemId_OnLookup), overrides); } } public class SalesTableFormExtensionOverrides { protected void new() { } public static SalesTableFormExtensionOverrides construct() { return new SalesTableFormExtensionOverrides(); } public void ItemId_OnLookup(FormStringControl _callingControl) { SysTableLookup sysTableLookup = SysTableLookup::newParameters(tableNum(InventTable), _callingControl); sysTableLookup.addLookupfield(fieldNum(InventTable, ItemId)); sysTableLookup.addLookupfield(fieldNum(InventTable, NameAlias)); sysTableLookup.performFormLookup(); } }

Hi Anton,

I want Delivery_DlvMode only show "X-Factory" option when SalesAgreementGenerateReleaseorder form open. I do not want want based on itemid on SalesAgreement line.

I am confused because Deliver_DlvMode control datasource is from SalesCreateReleaseOrderTableTmp.

Please give me more suggestions.

Thanks,

Faiz

Hi @Faiz,

The way you used is incorrect you must use an event handler for lookup.

the code below for the header lookup if you want to do it for the lines too you have to create an event handler for the Delivery_Line_DlvMode field with the same logic.

[FormControlEventHandler(formControlStr(SalesAgreementGenerateReleaseOrder, Delivery_DlvMode), FormControlEventType::Lookup)] public static void Delivery_DlvMode_OnLookup(FormControl sender, FormControlEventArgs e) { QueryBuildDataSource queryBuildDataSource; Query query = new Query(); SysTableLookup sysTableLookup = SysTableLookup::newParameters(tableNum(DlvMode), sender); // Add the lookup columns sysTableLookup.addLookupfield(fieldNum(DlvMode, Code)); sysTableLookup.addLookupfield(fieldNum(DlvMode, Txt)); // Add Range queryBuildDataSource = query.addDataSource(tableNum(DlvMode)); queryBuildDataSource.addRange(fieldnum(DlvMode, Code)).value(queryValue("X-Factory")); sysTableLookup.parmQuery(query); // Run the lookup sysTableLookup.performFormLookup(); //cancel the call to super() to prevent the system from trying to show //the lookup form twice and cause an error. FormControlCancelableSuperEventArgs cancelableSuperEventArgs = e as FormControlCancelableSuperEventArgs; cancelableSuperEventArgs.CancelSuperCall(); }

Best regards,
