Hi Andreas,

#Regarding ReadOnly property of the dataform editors

we have documented ‘How to set the readonly property for dataform editor in MAUI DataForm’ in our user guidance document. Please refer to the following UG documentation for your reference.

yes but i want to have a way to completely remove them from the dataform.

or in a more general way, a way to specify that only some properties are visible in the dataform.

since the DataObject comes from a libary i can not / want not to add Attributes to the class.

so maybe a way like if i use the  OnGenerateDataFormItem event to hide/remove selected properties from the DataForm

Andreas,

Your requirement can be achieved with the help of the GenerateDataFormItem event. Inside the event, we can check if the property of the model property is CanWrite or not and change the corresponding dataform editor's IsReadOnly or IsVisible property. Please refer to the code snippet for your reference.

Code Snippet

private void dataForm_GenerateDataFormItem(object sender, GenerateDataFormItemEventArgs e)

{

    if (e.DataFormItem != null)

    {

        var canWrite = dataForm.DataObject.GetType().GetProperty(e.DataFormItem.FieldName).CanWrite;

        if (!canWrite)

        {

            //// - set the IsReadOnly property to true

            e.DataFormItem.IsReadOnly = true;

            //// - set the IsVisible property to false

            e.DataFormItem.IsVisible = false;

        }

    }

}

Please refer to the demo sample in the attachment. Please let us know if you have any concerns.
