Adding dynamic field controls in the form

Hello All,

I am trying to add dynamic controls in the form. I have added a tabPage, a group and added field controls in the group.

The form is working fine, but the tab page is collapsed while opening the form. I tried to use tabPage.FastTabExpanded(FastTabExpanded::Always), the tab is expanded but the controls are not visible. If I set tabPage.FastTabExpanded(FastTabExpanded::Yes) fields are visible but tabpage is collapsed and have to extend them manually.

Adding the code for reference,

private FormGroupControl buildTabPageControl(){    FormGroupControl            groupControl;    FormTabPageControl          tabPageControl;    tabPageControl = callerTabControl.addControl(FormControlType::TabPage, 'TestTabPage' + enum2Str(FormControlType::TabPage),        callerInsertAfterControl ? callerInsertAfterControl : callerTabControl.controlNum(callerTabControl.controlCount()));    tabPageControl.caption('Test'');    if (callerTabControl.style() == TabStyle::FastTabs)    {        tabPageControl.fastTabExpanded(FastTabExpanded::Always);    }    groupControl = tabPageControl.addControl(FormControlType::Group, 'TestGroup'' + /@SYS80404/);    groupControl.arrangeMethod(FormArrangeMethod::HorizontalWrap);    return groupControl;}

Any insights or suggestions on what I might be missing or causing this behavior?

Hi WeKey,

Can you please share ur code again in the comments section, because it's not readable.

Are you saying in case u set it as always, none of the fields appear? Did u try to clear usage data?

Here's more info about the fastTab expanded property

Hi Wekey,

When I quickly scan your coding, I don't see fields being added. Can you share the full method in a new reply, please?

Hello Andre and Layan,

Thanks for the reply. I tried to add the code snippet I am not sure why the code looks that way. However adding the remaining code here

private FormGroupControl getFormGroupControl()
{
    FormGroupControl groupControl;

    groupControl = this.buildTabPageControl();        

    return groupControl;
}

void updateDesign(boolean _isDynamicControl = false)
{
    Map                 fieldsAdded;
    FormGroupControl    formGroupControl;        

    formGroupControl    = this.getFormGroupControl();
    fieldsAdded         = this.getAvailableField();

    if (_isDynamicControl)
    {
        this.addDynamicFieldsControl(formGroupControl, fieldsAdded);
    }
    else
    {
        
        this.addFieldsControl(formGroupControl, fieldsAdded);
    }
}

private void addDynamicFieldsControl(FormGroupControl _formGroupControl, Map _fieldsAdded)
{
    MapEnumerator   fieldsEnumerator = _fieldsAdded.getEnumerator();

    _formGroupControl.columns(_fieldsAdded.elements() ? _fieldsAdded.elements() : 1);

    while (fieldsEnumerator.moveNext())
    {
        str fieldType = Table::getFieldType(fieldsEnumerator.currentKey());

        switch (fieldType)
        {
            case enum2Str(FieldType::String):
                FormStringControl stringControl = _formGroupControl.addControl(FormControlType::String, fieldId2Name(tableNum(Table), fieldsEnumerator.currentKey()));
                stringControl.label(fieldsEnumerator.currentValue());
                stringControl.text(formDataSource.cursor().(fieldsEnumerator.currentKey()));
                stringControl.lookupButton(Table::exist(fieldsEnumerator.currentValue()) ? FormLookupButton::Always : FormLookupButton::Never);
                stringControl.registerOverrideMethod(methodStr(FormStringControl, lookup), methodStr(TestFormHelper, dynamicCtrlLookup), this);
                stringControl.registerOverrideMethod(methodStr(FormStringControl, modified), methodStr(TestFormHelper, dynamicCtrlModified), this);
                stringControl.cacheDataMethod(NoYes::Yes);
                break;

            case enum2Str(FieldType::Integer):
                FormIntControl intControl = _formGroupControl.addControl(FormControlType::Integer, fieldId2Name(tableNum(Table), fieldsEnumerator.currentKey()));
                intControl.label(fieldsEnumerator.currentValue());
                intControl.value(formDataSource.cursor().(fieldsEnumerator.currentKey()));
                break;

            case enum2Str(FieldType::Real):
                FormRealControl realControl = _formGroupControl.addControl(FormControlType::Real, fieldId2Name(tableNum(Table), fieldsEnumerator.currentKey()));
                realControl.label(fieldsEnumerator.currentValue());
                realControl.realValue(formDataSource.cursor().(fieldsEnumerator.currentKey()));
                break;

            case enum2Str(FieldType::Date):
                FormDateControl dateControl = _formGroupControl.addControl(FormControlType::Date, fieldId2Name(tableNum(Table), fieldsEnumerator.currentKey()));
                dateControl.label(fieldsEnumerator.currentValue());
                dateControl.dateValue(formDataSource.cursor().(fieldsEnumerator.currentKey()));
                break;

            case enum2Str(FieldType::DateTime):
                FormDateTimeControl dateTimeControl = _formGroupControl.addControl(FormControlType::DateTime, fieldId2Name(tableNum(Table), fieldsEnumerator.currentKey()));
                dateTimeControl.label(fieldsEnumerator.currentValue());
                dateTimeControl.dateTimeValue(formDataSource.cursor().(fieldsEnumerator.currentKey()));
                break;

            case enum2Str(FieldType::Checkbox):
                FormComboBoxControl comboBoxControl = _formGroupControl.addControl(FormControlType::ComboBox, fieldId2Name(tableNum(Table), fieldsEnumerator.currentKey()));
                comboBoxControl.label(fieldsEnumerator.currentValue());
                comboBoxControl.enumType(enumNum(TestEnum));
                comboBoxControl.selection(formDataSource.cursor().(fieldsEnumerator.currentKey()));
                break;

            default:
                //do nothing
                break;
        }
    }
}

private FormGroupControl buildTabPageControl()
{   
    FormGroupControl            groupControl;
    FormTabPageControl          tabPageControl;

    tabPageControl = callerTabControl.addControl(FormControlType::TabPage, 'Test' + enum2Str(FormControlType::TabPage),
        callerInsertAfterControl ? callerInsertAfterControl : callerTabControl.controlNum(callerTabControl.controlCount()));
    tabPageControl.caption("TestTabPage");

    groupControl = tabPageControl.addControl(FormControlType::Group, 'Test' + "@SYS80404");
    groupControl.arrangeMethod(FormArrangeMethod::HorizontalWrap);

    return groupControl;
}

Original code as it was not readable in the post

private FormGroupControl buildTabPageControl() { FormGroupControl groupControl; FormTabPageControl tabPageControl; tabPageControl = callerTabControl.addControl(FormControlType::TabPage, 'Test' + enum2Str(FormControlType::TabPage), callerInsertAfterControl ? callerInsertAfterControl : callerTabControl.controlNum(callerTabControl.controlCount())); tabPageControl.caption("Test TabPage"); if (callerTabControl.style() == TabStyle::FastTabs) { tabPageControl.fastTabExpanded(FastTabExpanded::Always); } groupControl = tabPageControl.addControl(FormControlType::Group, 'Test' + "@SYS80404"); groupControl.arrangeMethod(FormArrangeMethod::HorizontalWrap); return groupControl; }

Also I tried to get the tabPageControl and do the same tabPageControl.fastTabExpanded(FastTabExpanded::Always); after adding the fields to the group, still no luck with that it behaves the same. If I set the FastTabExpanded::Yes (Anything expect Always) I can able to see the field but the tabpage is collapsed. When I set to Always the tabPage is expanded but couldn't able to see the fields.
