Hi,

I'm having trouble getting a DataGridView to populate in this simple VB.NET forms application.

I'm going through, creating the dataset, adding columns and then rows, but when I run the program, no exceptions are thrown, but my datagrid view is completely empty.

Can anyone suggest what might be wrong here?

Cheers
Imports ToDoListLibrary

Imports System.IO

Imports System.Data.SqlClient

 

 

Public Class ToDoListUI

 

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

 

        Dim toDoItem = New ToDoItem()

 

        toDoItem.ToDoItemDoneProperty() = False

        toDoItem.ToDoItemDoneDateTimeProperty() = DateTime.Now

        toDoItem.ToDoItemDoByDateTimeProperty() = DateTime.Now

        toDoItem.ToDoItemTextProperty() = ""

        toDoItem.ToDoItemPriorityProperty() = toDoItem.ToDoItemPriorityProperty().High

 

        Dim toDoList = New ToDoList()

 

        toDoList.ToDoItemListProperty().Add(toDoItem)

 

 

        Dim ds As DataSet = New DataSet()

 

        Dim tb As DataTable = ds.Tables.Add()

 

        tb.Columns.Add("ToDoItemDone", GetType(Boolean))

        tb.Columns.Add("ToDoItemDoneDateTime", GetType(DateTime))

        tb.Columns.Add("ToDoItemDoByDateTime", GetType(DateTime))

        tb.Columns.Add("ToDoItemText", GetType(String))

        tb.Columns.Add("ToDoItemPriority", GetType(ToDoItem.ToDoItemPriority))

 

 

        For Each toDo As ToDoItem In toDoList.ToDoItemListProperty()

 

            tb.Rows.Add(toDo.ToDoItemDoneProperty, toDo.ToDoItemDoneDateTimeProperty, _

                         toDo.ToDoItemDoByDateTimeProperty, toDo.ToDoItemTextProperty, _

                         toDo.ToDoItemPriorityProperty)

        Next

 

        m_toDoListUIDataGridView.DataSource = ds.DefaultViewManager

 

    End Sub

 

 

End Class

Hi Cognize,

Try to use this line:

m_toDoListUIDataGridView.DataSource = ds.Tables(0)

or

m_toDoListUIDataGridView.DataSource = dt

Regards,

Falcko
