Asp.net's ObjectDataSource data bind event

Question

Hi there I'm Working on an Asp.net/C# application. I want to bind a list of objects to a grid view. I've been looking a while to the ObjectDataSource control and it loads data to my datagrid as soon as my page loads. Can I change this behaviour? For example, how can I set DataBinding only when a button on my page gets clicked?

tks

Answer 1

You can create the objectdatasource in the code behind and do the bind onclick.

Answer 2

You can hook into the ObjectDataSource's Selecting event and cancel any selects that don't match the criteria you're looking for. I do this all the time based on values in other controls.

Look at the e.Cancel property for that event.

Answer 3

Do not set the datasource in markup and simply do it in the code-behind on the OnClick event of the button.

Programatically, you can specify the object to bind to as shown in the answer to this question...
