While working on my code backend, I encountered a peculiar issue with the JavaScript array registration. At times, instead of registering the actual values, commas are being placed in the array.
Here are two scenarios showcasing different outcomes:
oData Table 1:
statustype | orderstatus | ordercount
6 | received | 6671
oData Table 2:
statustype | orderstatus | ordercount
8 | unknown | 1
4 | pending | 567
3 | in process | 117
1 | entered | 3
Dim sOrderStatus As String = String.Empty
Dim iOrderCount As New List(Of Integer)
With oData
If .Rows.Count = 0 Or sError.Length > 0 Then
Response.Write(GetErrorNotFound())
ddlWarehouses.Visible = False
lblWarehouse.Visible = False
Else
For Each oRow In .Rows
sOrderStatus = sOrderStatus & "'" & oRow.Item("OrderStatus").ToString & "',"
iOrderCount.Add(CInt(oRow.Item("ordercount")))
Next
'Convert to an array and then register as a JavaScript array
Dim orderArray As Integer() = iOrderCount.ToArray
For s = 0 To orderArray.Count - 1
Page.ClientScript.RegisterArrayDeclaration("orderArray", CStr(orderArray(s)))
Next
'Remove extra comma and register as a JavaScript array
If sOrderStatus <> String.Empty Then
sOrderStatus = sOrderStatus.Remove(sOrderStatus.LastIndexOf(","), 1)
Page.ClientScript.RegisterArrayDeclaration("generatedLabels", sOrderStatus)
End If
End If
End With
Javascript:
alert("length: " + orderArray.length);
alert(orderArray.toString());
Outcome 1:
length: 6671

Outcome 2:
length: 4

Edit: I've stumbled upon something intriguing. When declaring an integer array with multiple values, everything functions correctly but when only one value is declared, the issue arises. Could this be a bug??
Any assistance or pointers would be highly appreciated.
