I want then LLBLGenProDataSource2 do not perfrom a select when the page load first time,that is the Page.IsPostbakc=false.

There are some controls in my page to create a filter for the datasource control.I want the datasource control execute a select action only when I click a "Query" button.When the page load for the first time(not postback),I want the datasource control do nothing. As the mess data in db,if no filter use,the page will load slowly.That's what I not want. Is there such a property for LLBLGenProDataSource2 like "Enable" I can use for

Page_Load() { if(!IsPostBack) { datasource.Enable=false;//Should do nothing } else { //perform a select action } }

And at current,I have to use a absolutely "False" filter such as "1=2" and so on to perform this function.

Try this:

if (!IsPostBack)            
{
    LLBLGenProDataSource21.Refetch = false;
}

And when you perform the search (btnSearch_Click, for instance), set it to true.

NO,it still select all records

I think as long as it's set to to some controls it will automatically fetch the records once that control is loaded.

So what you can try is to remove this association from the aspx code, and later in code when you want it to fetch the records associate it to the appropriate control's DataSource property, and call DataBind() of the control.
