Commit via Button

Emad Afaq

Asked On January 9, 2020 05:37 AM UTC

How do i access the values from the individual fields when a button action is performed and validation is done? I want to pass those values to a rest service. what will be the best approach?

private void OnCommit(object dataForm)

{

var dataFormLayout = dataForm as Syncfusion.XForms.DataForm.SfDataForm;

var isValid = dataFormLayout.Validate();

dataFormLayout.Commit();

if (!isValid)

{

App.Current.MainPage.DisplayAlert("Alert", "Please enter valid details", "Ok");

return;

}

App.Current.MainPage.DisplayAlert("Alert", "Money Transferred", "Ok"); // Here I want to perform the API Call.

dataFormLayout.IsReadOnly = true;

this.IsVisible = false;

}

Hi Emad,

Thank you for contacting Syncfusion support.

Based on the shared information we have checked your requirement of “Accessing field values after DataForm commit”. DataForm DataObject will hold the committed values of each field, you can get the entire class or individual field values from DataObject of DataForm.

Please refer the following code example for the same,

[C#]

private void OnCommit(object dataForm)

{

var dataFormLayout = dataForm as Syncfusion.XForms.DataForm.SfDataForm;

var isValid = dataFormLayout.Validate();

dataFormLayout.Commit();

//Gets value of model class

var model = dataFormLayout.DataObject;

//Gets individual field values

var firstName = (dataFormLayout.DataObject as ContactsInfo).FirstName;

var lastName = (dataFormLayout.DataObject as ContactsInfo).LastName;

var email = (dataFormLayout.DataObject as ContactsInfo).Email;

var contactNumber = (dataFormLayout.DataObject as ContactsInfo).ContactNumber;

}

We have prepared a sample based on your requirement,
