Item Not Found

[Frederick Switzer]

When trying to save items from my SfDataForm, items that are marked as [DataType(DataType.Date)] for example the item.Value is not present.

Here is my object decoration:

[Display(GroupName = "Basic", Name = "DOB")]
  [DataFormDisplayOptions(RowOrder = 2, ItemsOrderInRow = 0)]
  [Required(ErrorMessage = "DOB is required")]
  [DataType(DataType.Date)]
  public string DOB { get; set; }

And here is my On Save Method:

private async void saveButton_Clicked(object sender, EventArgs e)
  {
      Patient patient = new Patient();


      if (this.patientDataForm.Items != null)
      {
          foreach (var viewItem in this.patientDataForm.Items)
          {
              if (viewItem is DataFormItem dataFormItem)
              {
                  string fieldName = dataFormItem.FieldName;
                  string labelText = dataFormItem.LabelText;
                  var value = dataFormItem.GetValue();
              }


              if (viewItem is DataFormGroupItem groupItem)
              {
                  var groupItems = groupItem.Items;


                  foreach (var item in groupItems)
                  {
                      string fieldName = item.FieldName;
                      string labelText = item.LabelText;
                      var value = item.GetValue();




                      if (fieldName == "DOB")
                      {
                          patient.DOB = (value != null) ? value.ToString() : " ";
                          Debug.WriteLine($"DOB Value: {patient.DOB}");
                      }






                      if (fieldName == "fname")
                      {
                          patient.fname = (value != null) ? value.ToString() : " ";
                      }


}
}
    }
}

How do I find the object?

Hi Frederick,

Thank you for reaching out to us. To ensure the Date editor in SfDataForm correctly retrieves and binds the value, please define the `DOB` property as `DateTime` instead of a string. Here’s the correct approach:  

 

[Display(GroupName = "Basic", Name = "DOB")]

[DataFormDisplayOptions(RowOrder = 2, ItemsOrderInRow = 0)]

[Required(ErrorMessage = "DOB is required")]

[DataType(DataType.Date)]

public DateTime DOB { get; set; }

 

private async void saveButton_Clicked(object sender, EventArgs e)

{

    Patient patient = new Patient();

 

    if (this.patientDataForm.Items != null)

    {

        foreach (var viewItem in this.patientDataForm.Items)

        {

            if (viewItem is DataFormItem dataFormItem)

            {

                string fieldName = dataFormItem.FieldName;

                string labelText = dataFormItem.LabelText;

                var value = dataFormItem.GetValue();

            }

 

            if (viewItem is DataFormGroupItem groupItem)

            {

                var groupItems = groupItem.Items;

 

                foreach (var item in groupItems)

                {

                    string fieldName = item.FieldName;

                    string labelText = item.LabelText;

                    var value = item.GetValue();

 

                    if (fieldName == "DOB")

                    {

                        if (value is DateTime dateValue)

                        {

                            Debug.WriteLine($"DOB Value: {dateValue.Date.ToString()}");

                        }  

                    }

 

                    if (fieldName == "fname")

                    {

                        patient.fname = (value != null) ? value.ToString() : " ";

                    }

                }

            }

        }

    }

}
