I have a form called studentForm which has a studentCombobox, studentTextbox and a studentDatagridView
In the constructor of the studentForm I need to bind studentCombobox to the StudentbindingSource of the main form and to bind studentDataGridView to appropriate binding source in the mainForm.So that this datagrid view displays all the bookings for the studentID currently selected in studentComboBox
studentComboBox.DataSource = MainForm.StudentBindingSource
studentComboBox.DisplayMember = "StudentID"
studentDataGridView.DataSource = MainForm.StudentDataSet
studentDataGridView.DataMember = "Names "
This is the code I wrote in the constructor
I am trying to bind data from a text box on my form to a field in my database table. First of all I have created a DataSet, BindingSource and Table Adapter in the forms Design view, but I am having from there. Under the properties of each text box I have set the DataBindings (Text) to the field in the table under the forms instance and DataSet rather than the Projects Data Sources. I am very rusty at Visual Studio 2005 and that is all I have to work with.

View 10 RepliesI have the following XML file:
<?xml version="1.0" encoding="utf-8" ?>
<root>
<Language code="0" control="form" attribute="text">
<NL>Upload expansies</NL>
<UK>Upload expansions</UK>
</Language>

I would like to bind the text between the NL or UK tags, based on a setting, to the control with the name in the attribute "control".
I started with this:
Dim xf As New Xml.XmlDocument

I am thinking I need to do something like a search in the xmldocument for the specific control, then get the text from the children.

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.

View 1 RepliesIt'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?
