[CLOSED] Grid Panel editing
I am trying to prevent editing based on a value in code behind. In the example the statement "if 1=2" would be some business logic/condition. I am returning false thinking that should prevent editing but it does not.
<%@ Page Language="vb" %>
<script runat="server">
Private Class GridDTO
Property ID As Integer
Property Trade As Boolean = True
Property Type As String
Property ChangeGuidance As String
End Class
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack AndAlso Not Ext.Net.X.IsAjaxRequest Then
Dim data As New List(Of GridDTO)
Dim X = New GridDTO With {.ID = 1, .Trade = True, .ChangeGuidance = ""}
data.Add(X)
X = New GridDTO With {.ID = 2, .Trade = True, .ChangeGuidance = "Test Guidance"}
data.Add(X)
X = New GridDTO With {.ID = 3, .Trade = False, .ChangeGuidance = ""}
data.Add(X)
storeVerification.DataSource = data
storeVerification.DataBind()
End If
End Sub
<DirectMethod([Namespace]:="ModelHoldingsGrid")>
Public Function BeforeEdit() As Boolean
If 1 = 2 Then
Return True
Else
Return False
End If
End Function
<DirectMethod([Namespace]:="VerificationGrid")>
Public Sub Edit(id As Integer)
Me.grdAllocationsVerification.GetStore().GetById(id).Commit()
End Sub
