Updating sql database from a listbox

The key of data binding is the Binding attribute of a control in XAML.

The Binding attribute takes a property of the data source.

For example, we are binding a Text Block with Contact Name in the below code.

Now I add a List Box control and set its Items Source property as the first Data Table of the Data Set and set Item Template to the resource defined above.

Immediately the listbox is filled with "datarowview". Load *** some code deleted here for brevity *** Key Ds. On the general issues, of whether (a) Selected Index Changed is fired by an addition to a bound list and (b) it is the right event to use for your purpose, I think the answers are "Yes" and "Yes". But if re-doing the binding solves the display problem, will you be happy with that?

I added an item to the listbox and then I navigate to new values in the list box clicking the button after each move to update the datagrid. So why would the very same code not work in listbox_Selected Index Chang Sure, here's the code. I can see the seconds change in the label as I navigate the list box. Display Member = "Keyword" (to which it was previously set) did not fire the event in those. Roger Roger, It seems the only thing I can do to "fix" this is to put List Box1.Using bind variables also improves query performance in the database, eliminates the need for special handling of literal quotation marks in the input, and protects against SQL injection attacks.The following code shows a typical contains a client copy of the database data.Your XML data is "shredded" by OPENXML into a table, whence you can perform an update using all the input data.In the example above, each item tag would shredded into a row, each attribute name (name, value), becomes a column, and the values of the attributes are the field values for the columns.
