[RESOLVED] [2005] Getting data back from a user control to a parent control

[steve_rm]

Hello,

I have a user control. See the image below. The tab control is not part of the user control. but everything inside is.

When a user wants to delete a task the taskID is taken from the tab name and passed to the user control in a public property. So I know what task I want to delete.

'Code in the user control
Public Property TaskID() As Integer
        Get
            Return _taskID
        End Get
        Set(ByVal value As Integer)
            _taskID = value
        End Set
    End Property

'

In the parent form I get the TaskID from the tab name and pass it to the public property
Private Sub TabControl1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TabControl1.Click
        Try
            Dim taskID As Integer = 0

            taskID = Integer.Parse(Me.TabControl1.SelectedTab.Name)
            newTask.TaskID = taskID
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try
    End Sub

But the problem is when I delete I want to be sure that the deletion was successful and pass this back to the parent control. And that is something I can't see to do.

For example: if there was a problem with the delete then I don't want to delete the tab but inform the user there was a problem.

'code in the user control for deleting the task, but if not successful, how do i send this back to the parent control?
Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click
        Try
            Dim rowsAffected As Integer = 0
            rowsAffected = Me.TA_IncidentTask1.DeleteTask(_taskID)
            If (rowsAffected = 0) Then
               'Not successful so how do i inform the user
            End If
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try
    End Sub

I am ok at passing information to the user control by using public properties as you have seen in the code above. But i need to know if the delete was successful or not.

Can anyone help and advice me on this. code examples would be most grateful.

Many thanks,
