I have a Master Page with nested pages in ASP.NET. Fairly simply I want to databind some hyperlinks to a gridview for the master page. This however is throwing a null reference exception when I try to set the DataSource.
I tested the code on a separate page and it works as expected. When debugging I can see the Page_Load Sub hit twice, I don't know if this is the cause I have one nested page being loaded, this is a blank page at the moment
EXCEPTION Object reference not set to an instance of an object. MASTERPAGE CODE BEHIND Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

It's been a long while since I've done any VB.Net coding and need to bind some data to a form. I have multiple tables that share some common primary/foreign keys and need to easily be able to update them.
For example, I have a table with an ObjectID, TypeID, AreaID, and several other fields. When doing my layout, I need the TypeID (found only in the main table) to be a distinct value in a comboBox, and in the ComboBox which contains the Area to be the Area Description (from the main table tied to the Area table via the Area ID).
I have the following overloaded functions I use to fill a combobox.The first function works the way I want it to except for the fact that I pass a combobox in. I wanted to create a simpler function, thus my second attempt.For some reason the line:tempCombobox.DataSource = tempTable does not bind the data table to the tempCombobox. What am I doing wrong?

I need to create a new tree view, that is linked to a particular table.
Each row in the table has a parent id that links back to the table's primary key, and that defines the node hierarchy. So that relationship needs to be indicated in the databinding.
Am I able to use the standard treeview control in Visual Studio 2008, or do I need something extra to make this work?

In silverlight, can you bind to a property that contains parameter? For example, the following doesnt seem to work. Am I missing something or is this not possible?
