Checkbox not updating Datacardvalue

[nchandran]

Hi,

I have a checkbox when checked changes a particular text field datacardvalue in a form to "NA" and then when checkbox is unchecked sets to "".

This was working when i created a new canvas app and practised the code. however when i used the same concept on my app , the form text field says name isn't valid, identifier isn't recognised. 

Text Field is a Datacardvalue where default property is RT1

This is the code for the checkbox -> On check property: If(true, UpdateContext({RT1:"NA"})), On Uncheck property: If(true,UpdateContext({RT1:""})). Screenshots belows shows the parent Datacard default property and 2nd screenshot shows the datacardvalue default property .

Hi @nchandran 

OnCheck Checkbox

 If(Checkbox3.Value, UpdateContext({RT1:"NA"}))

OnUnchecked Checkbox

 If(!Checkbox3.Value, UpdateContext({RT1:Blank()}))

If use your form for Edit and New Use this code on the Datacard Default

 If( YourFormName.Mode = FormMode.New,RT1,             ThisItem.EQUIPMENU)

Change Checkbox3  and YourFormName  whatever your control name  also RT1 add Default datacard EQUIPMENU the control you wanted to reset. to "NA"

Let me know if you need any more assistance

Hi  @nchandran 

Please fellow this as i see there's typo error on control names and make sure you use my formulas whole Not this If(true, UpdateContext({RT1:"NA"}))

, so lets rename your form name  FormLoans to same on the code 

If(FormLoans.Mode = FormMode.New,RT1,ThisItem.EQUIPMENU)

Checkbox OnCheck  copy the formula whole and paste OnCheck 

 If(Checkbox4.Value, UpdateContext({RT1:"NA"}))

Rename your checkbox to Checkbox4

Checkbox  - OnUncheck 

 If(!Checkbox4.Value, UpdateContext({RT1:Blank()}))

I have tested my end and its working here what I get

Let me know if you need any assistance

Facing this error on the DataCard default property. Aren't we suppose to place this in the datacardvalue then the datacard? ok anyway its not working.

[Ramole]

did you paste below codes to checkbox first as you will need Variable to be valid before the datacard RT1 to work 

Oncheck 

 If(Checkbox4.Value, UpdateContext({RT1:"NA"}))

Uncheck

 If(!Checkbox4.Value, UpdateContext({RT1:Blank()}))

Then add the Datacard the 

If(FormLoans.Mode = FormMode.New,RT1,ThisItem.EQUIPMENU)

@nchandran 

Did you add this code to checkbox? first and make sure you name the checkbox Checkbox4 

If(Checkbox4.Value, UpdateContext({RT1:"NA"}))

@nchandran 

I Did not ask this where is the checkbox placed, same screen where the Form is,  or in a different Screen ?

If its same screen use same code I give you before.

If NOT then you will need a variable global in other words, a variable that is visible from all other screens within your app so we will need to modify our old formula.

CheckBox   -  OnCheck

  If(Checkbox4.Value, Set(RT1,"NA"))

CheckBox   -  Uncheck

 If(!Checkbox4.Value, Set(RT1,Blank()))

DataCard 

If(FormLoans.Mode = FormMode.New,RT1,ThisItem.EQUIPMENU)
