Environment: VS2005, ASP.Net 2.0, SQLServer 2000, VB.Net, IIS6
I use a GridView Control which is based on a SQLDataSource. The datasource
is based on a Select statement and is filtered by the FilterExpressio n. The
GridView also has a pager element (below, displaying first, previous, next,
last icons), paging is enabled, page contains 10 rows.
The user now skips some pages by clicking a view times on the next icon.
Now he changes the filter by entering a text in a text box.
This .Text property is thenafter used to set the
SQLDataSource.F ilterExpression .
The displayed rows are correctly filtered and displayed, and paging works
fine. The only thing I don't understand is, why the pager doesn't reset to
page 1 if I change the FilterExpressio n. It just displays a page within the
resultset, not the first one. I even didn't find what page it displays, must
be an index or something it uses as it's not the same pagenumber as I had
before.
I also didn't find the method to request the first page after I've changed
the FilterExpressio n else I would use the textbox's TextChanged event to
reset the pager control to start at page 1.
Any idea how to do this? Or is it a bug? Do I have to do a workaround or
even stop using the FilterExpressio n and instead change the SQLCommand of
the SQLDataSource and manipulate the WHERE clause inside? I expect this
would result in disposing the cache and re-reading all records, what I don't
like for performance reasons.
Thanks for any hints on how to display the first page of a GridView control
programmaticall y after the FilterExpressio n of the SQLDataSource has
changed!

Got the answer:
<GridName>.Page Index = 0
works fine. Must have been blind!

Hello,
Does anyone have an idea on how I can filter the data in the gridview
control that was returned by an sql query?
I have a gridview that works fine when I populate it with data. Now I want
to look at that data and filter it based on what is in it.
I know that this could have been done with data sets and data views in
asp.net 1.1 but how is this done now in asp.net 2.0?

Hello,
I've been playing with master/detail views as well as editing in the

I have 2 tables, a table of cars (pretty basic, an ID, a description, and a
Color ID) and a table of colors (Color ID, and a color description). I've
added a gridview and a detailsview as I'm playing with both and how to get

I have a number of simple select queries that a user needs to be able to
execute and display the data on the screen in a gridview. My thought was
that I could use a Gridview set to dymanically generate columns and bound to
a SQLDataSource. Then the user can click buttons (or whatever) and it
changes the SelectCommand property of the SQLDataSource and re-binds the
GridView.
That worked great until I enabled paging. When paging is...

I have a Gridview displaying the results of a stored procedure. The
stored procedure is constantly changing so the columns displayed in the
data grid are constantly changing. I'd like to give users the ability
to filter by the value of any column. This is easily done using the
FilterExpression property of the DataSource. However, prior to
creating the filter expression, I need to know if the column they wish
to filter contains text or...

Here is an example of what I believe is a bug in ASP.NET 2.0 GridView paging

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
