Programmatical Parameters w/MultiRowEdit on DataGrid

[Derek]

I have an aspx page where I use a reversebind and
templates to edit the entire datagrid at one time. I
added a textbox and button to change the parameter
criteria and then rerun the databind2 procedure. That
works fine the data is requeried and the new results are
displayed in the datagrid and the reversebind works for
saving the information. However if I add another text
box or dropdown box it does not seem to requery
correctly. If I remove the reversebind it will, but
without the reversebind I can not save changes to the
datagrid as a whole. I think I understand why using the
ddcp.selectedindex change sub will not work because it is
posting back however I can not figure out why adding an
additional text box for input and placing that within the
button1 command is not. I have looked at the stored
procedure also. I need to be able to either look at all
or a particular type of cp. I would prefer to use a drop
down box either inside or out of the button1 command.
Any help would appreciated. Thanks in advance

Here is both the code for page and stored_proc. page
also draws really slow:

Hi Derek,

I am not confident that I have understood the problem clearly. Did you need
to add a TextBox or Dropdownlist to let user select some values, and then
requery the database. If so, after user input the value and click a button
to post back, you need to execute BindData2() in PostBack, Is this right?

Yes, I want to call binddata2() on button1_click. It
seems the reverse bind is causing the issue however If I
remove that I can not use the save btn update the
database with multiple selections.



The page is set up so that on load if notispostback it
executes Binddata2() else it executes reversebind(). On
the page load the stored procedure is sent all default
parameters (%) to pull all the data. When the daysout
textbox receives input and the go button is clicked
Binddata2() is called and requeries fine. It is when I
add another textbox asking for input for another filter
parameter that it does not execute the stored procedure
correctly. Example they choose to filter based on "p".
It does not change the parameter to pull records only
with "p". The confusing part is that it will execute
binddata2() with the one textbox.

I would prefer to use the dropdown box with or without
the GO btn but if I could get the text box to work that
would be great. The stored procedure works fine in query
analyzer.

Hope this gives you a little more information.
I am including the Html which may help you to see what I
am trying to do. Thanks for your help, it is appreciated
very much

Hi Derek,

The problem is that when you click the button1, it is also a postback so
that the reverse update also get executed. Is possible to move
ReverseUpdate out of Form load and add it in the Save/Update button's Click?
