.NET (Core and Framework)

This is Tarun

I want to do CRUD Operations in Windows Forms Using Entity Framework.

Would you please tell me how to do this.

I already tried this article <a href="http://www.codeproject.com/Articles/221931/Entity-Framework-in-WinForms">Entity Framework in WinForms</a>[<a href="http://www.codeproject.com/Articles/221931/Entity-Framework-in-WinForms" target="_blank" title="New Window">^</a>] But Here It did n't enable entitydatasource control in this.

Kindly Reply me

protected void btnEdit_Click(object sender, EventArgs e)
    {
        try
        {
            GridViewRow row = ((LinkButton)sender).Parent.Parent as GridViewRow;
            HiddenField vId = (HiddenField)gvUser.Rows[row.RowIndex].FindControl("hdPK");
            form obj = new form(cmscon.CONNECTIONSTRING, Convert.ToInt32(vId.Value));
            GetValue(obj);
            Label1.Text = "";
            lblError.InnerHtml = "";
        }
        catch (Exception ex)
        {

        }
    }

<asp:TemplateField HeaderText="Action">
                    <ItemTemplate>
                           <asp:HiddenField ID="hdPK" runat="server" Value='<%# Eval("Id") %>' />
                           <asp:LinkButton ID="btnEdit" runat="server" OnClick="btnEdit_Click" CausesValidation="false">Edit</asp:LinkButton>
                           &nbsp;&nbsp;
