Retaining Current Values Of DropDown List inside a Form View Control
I have two dropdownlist controls inside a formview control which lists the "genre" and "rating" for a video game. The two dropdownlist are bound to an objectdatasource which extracts the "genre" item and "rating" item.

With this in mind, i manually added "listitems" in order for the user to have a selection of all the "genre" and "rating" fields. My problem is when i ...

Can a DataSource set the default value in a DropDownList (or the list fetch the value from a DataSource)?
Hi
I have a DropDownList that gets its values from a DataSource-control. Nothing magic so far. What makes me scratch my head is that I need to set the default (selected) value in the drop down.
As the values come from a data source, I do not know the key/value/index of the default I. Is there a possibility to make the drop down "ask the data source" which key should be the default (that is, only if the drop down is populated the first time, of course)?
Background: I have an application where an administrator can set the "standard" month that the application s...

Dropdown list binds to previous datasource value
I've created a custom drop down list by inheriting dropdownlist, and done a number of modifications to the DataSource property. The problem is that when I set the DataSource on the dropdown list it binds to the DataSource Previously set. Consider the following form: My modified dropdownlist is on the left, Each of the buttons modifies the data source and causes the dropdownlist to databind. However only button 153 causes any values to appear in the list (this is intended). Here's a scenario:The page loads and the Drop Down List empty because no datasource has be...
