GridView overriding InitializePager

[Andrew Robinson]

I am overriding the InitializePager method on a grid view and displaying a
customized pager. Is there any way to insure that the method is always
called even if the number of rows is less than the page size? One of the
functions that I am adding is the ability to change the page size but once
the user shows "all" rows, there is no way to get back to the pager and thus
reduce the page size.

Thanks,

Hi Andrew,

As for the GridView control, the "InitializePager " method is called by the
"CreateRow" method which is further called by "CreateChildControls", you
can check it through the reflector tool:

=========
protected override int CreateChildControls(IEnumerable dataSource, bool
dataBinding)
{
....
=========

the problem here is that "GridView.CreateChildControls" will always check
the DataSource's itemset to see whether it is pageable, and only when it is
pagable will it create the pager, there hasn't exposed a built-in interface
for us to force the pager be displayed.

If you do want to display some infomration when the records count is not
pagable, do you think it is possible to use the GridView footer to display
them or manually use a wrapper table around the gridview to display the
information?
