Hi All,

I want to create contacts view. My model is:

public class Contact
{
    public Contact()
    {
        Documents = new HashSet<Document>();
    }

    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string ContactNo { get; set; }
    public string EmailId { get; set; }
    public string Address { get; set; }
    public string Notes { get; set; }
    public ICollection<Document> Documents { get; set; }
}

public class Document
{
    public Document() { }

    public int Id { get; set; }
    public int ContactId { get; set; }
    public string DocumentNo { get; set; }
    public string DocumentType { get; set; }
    public byte[] FileContent { get; set; }
    public string FileName { get; set; }
    public int ContentLength { get; set; }
}

I have created view with Contact details and Grid for documents. Actually I am new to MVC so I am searched internet how to achieve this. But I cannot find any workable solution yet. I do not know how to add one or more document and persist document details in grid.  What I am trying to achieve is save contact information with uploaded documents (one or more) while submit the form.


Thanks in advance.

Hello Arun,

I recommend you going through the following articles which explains how to implement hierarchy and CRUD operations:
 - Client Hierarchy
 - Ajax Editing

You can also check the following forum thread for sample implementation of upload as editor: upload-in-grid-custom-editor.

Hello Arun,

Unfortunately from the provided code we are not able to assemble a runnable project. Thus I've created an  example using Upload in Grid edit form.

Can you modify it so that it replicates the issue which you are facing?
