FormCheckboxControl.checked(true) is not reflected on UI

Hi everyone, I have a question regarding the customization in Dynamics 365 Finance and Operations. I customize some fields on the DirPartyQuickCreateForm. The fields are the customized fields that I created in CustTable. Two of them are the checkbox control.

In my code which is written in the DirPartyQuickCreateForm_OnInitialized(), the /e-Invoice/ checkbox is represented with eInvCB, while /Consolidate E-Invoice/ is represented as consoCB. I tried to set eInvCB.autoDeclaration(true); eInvCB.checked(true) and same goes for the consoCB variable. When I debugged, I could see the value of my eInvCB was equal to 1, but the UI still showed unchecked.

For this issue, I tried to set eInvCB.value(1) but the UI remains unchanged. So, I would like to know if there is any way to check the checkbox when the form is initialized.

I appreciate any suggestions and guidance provided.

Thanks and regards,

Yue

Hi Yue,

Do you mean when you first open the form, the flag appear as false but when debugging they appear as true?

Also please share with us your code

Did you try run method something like this? Try defaulting with 1 instead true like below.

eInvCB.checked(1);

Hi,

You can try this code :

FormCheckBoxControl yourCheckBox = sender.design().controlName(formControlStr(YourFormName,YourControlName)) as FormCheckBoxControl; yourCheckBox.value(enum2int(NoYes::No));

Thanks,

If it's bound to a data source, set a value of the datasource field (e.g. custTable.MyField = true) instead of setting the value of the control itself.

I tried to create the new customer record and I found that the checkbox is still showing unchecked and the value stored in the table in SSMS is 0. I tried to write _custTable.ads_EInvCheckbox = true or
FormCheckBoxControl einvCB = sender.design().controlName(strFmt("%1_%2", formControlStr(DirPartyQuickCreateForm, DynamicDetail), fieldStr(CustTable, ads_EInvCheckbox))) as FormCheckBoxControl;
einvCB.value(enum2int(NoYes::Yes));

or

einvCB.checked(1);

but all of them are not working for my case. I did tried to set allowEdit(false), it worked.

I made it! I found out that I should use CoC to extend the data source and override its initValue() method to set the checkbox value default to 1.

Hi,

As Martin mentioned, looks like your control is bounded to the form data source. You need to first retrieve the form DataSource buffer and then retrieve the FormCheckboxControl buffer through the formDataSource buffer.

1. Sample code correction.

final class DirPartyQuickCreateFrom_Form_Handler { /// <summary> /// /// </summary> /// <param name="sender"></param> /// <param name="e"></param> [FormEventHandler(formStr(DirPartyQuickCreateForm), FormEventType::Initialized)] public static void DirPartyQuickCreateForm_OnInitialized(xFormRun sender, FormEventArgs e) { ads_ConsoEInvoiceParameters consoParameters; CustTable _custTable; FormCheckBoxControl einvCB = sender.design().controlName("<einvCBControlName"); //strFmt("%1_%2", formControlStr(DirPartyQuickCreateForm, DynamicDetail), fieldStr(CustTable, ads_EInvCheckbox))); //Modification FormCheckBoxControl consoCB = sender.design().controlName("<consolidateeinvoicecontrolname>"); //strFmt("%1_%2", formControlStr(DirPartyQuickCreateForm, DynamicDetail), // fieldStr(CustTable, ads_ConsolidateEInvCheckbox))) as FormCheckBoxControl; FormStringControl tin = sender.design().controlName(strFmt("%1_%2", formControlStr(DirPartyQuickCreateForm, DynamicDetail), fieldStr(CustTable, ads_TIN))); FormStringControl ic = sender.design().controlName(strFmt("%1_%2", formControlStr(DirPartyQuickCreateForm, DynamicDetail), fieldStr(CustTable, IdentificationNumber))); ic.label("Business registration/ identification/ passport number "); consoCB.autoDeclaration(true); einvCB.autoDeclaration(true); //einvCB.value(enum2int(NoYes::Yes)); _custTable.ads_EInvCheckbox = 1; //Remove this and add a code in the find() method on the table ads_ConsoEInvoiceParameters select * from consoParameters; if(consoParameters.ads_ConsolidateEInvCheckbox == 1) { consoCB.checked(true); } else { consoCB.checked(false); tin.mandatory(true); ic.mandatory(true); } } }

Tested the sample code on my sample development machine and this works.

2. Also, eliminate the statement from the OnInitialized event handler method. Instead add a find() method and add the select * from consoParamters in that find() method of the table ads_ConsoEInvoiceParameters.

select * from consoParamters

Adopt a similar approach for the
