Data form

Question

i tried adding the data form to a xamarin.forms project last night and it doesnt show up if its inside a stacklayout. Is that expected?Also, how do you override the text of a label?Thanks!

Ah, I figured it out.  I think because the content is dynamically generated, the StackLayout doesn't know how to show it properly.  I changed to a grid and its fine.

Hi Danny, 
 
Thanks for contacting Syncfusion support. 
 
We have checked your query and we are unable to meet your scenario “SfDataForm loading inside the StakLayout”. We have ensured this scenario with Syncfusion Product Version 16.1.0.32 and the SfDataForm working fine in our side. If SfDataForm’s dataobject is not binding properly, then the DataForm height becomes zero. 
 
We have attached the tested sample along with this response. Please find the same from below.

Hi Danny, 
 
Regading Override text of Label 
 
Way 1: 
You can change text of Label by using DataAnnotation attributes in Entity collection. 
 
Please refer the below code example 




// ShortName shown as text of Label 
[Display(ShortName = "Collection Details")] 
        public string Collection 
        { 
            get 
            { 
                return collection; 
            } 
            set 
            { 
                this.collection = value; 
            } 
        } 
 
Way 2: 
You can change text of Label using AutoGeneratingDataFormItem event. 
 
Code example 




        dataForm.AutoGeneratingDataFormItem += DataForm_AutoGeneratingDataFormItem; 
        dataForm.DataObject = new ContactsInfo();                      
        
 
        private void DataForm_AutoGeneratingDataFormItem(object sender, AutoGeneratingDataFormItemEventArgs e) 
        { 
            if (e.DataFormItem != null && e.DataFormItem.Name == "Collection") 
            { 
                e.DataFormItem.LabelText = "Collection Details"; 
            } 
        }
