how do sharepoint pages load? - sharepoint

I need to understand the load sequence for a sharepoint page that uses a query string to filter content.
If I pass in a query string, I assume that SharePoint first passes that query string to any web parts that need it, waits for the web parts to load their content then loads the final page? OR does SharePoint first load the page then pass the query to its web parts.

The QueryString is acessible in your webparts, it gets passed at the very beginning of the request.

Web Part is just another Control in the Page and it behaves in the same way as other controls, so same Page Execution Cycle happens in the WebPart pages as well and the Query String will be always avaliable in your WebPart code.

How to take parameter from sharepoint and pass to SSRS report

What I have is a page in sharepoint that has a URL that points to the page the contains a parameter at the end, as in "ttp://theur|?Project=projname and what I need is to somehow pass the value of the Project parameter that is in that URL and pass it to the SSRS report so that I can use it on there. I am displaying the SSRS report on the sharepoint page as an SSRS report viewer web part.
If you're using the report viewer page, you can pass the parameter by appending rp:=value into the query string where is the name of the report parameter. For a web part embedded in a SharePoint you may be able to use a querystring filter web part and send the value to the report web part.

Create a web page in Orchard

I need to create a "custom" web page in Orchard. As I understand it, below are the steps I need to take to do so. Before I go down this somewhat lengthy process, are there any steps I'm missing or that I can skip?
Create a model
Create a content part and content part record which use the above model
Create a driver which implements the Display method which returns the "shape" of the content part
Create a shape template to render the shape returned from the above driver
Create a content type which holds the content part
Create a page which holds the content type
Add the page to my site
This page is "custom", in the sense that it needs to pull data from a web service and display it in an interactive way. When the user makes changes, those changes will need to be sent back to the web service.
Those are really steps for creating a content item. You would want to create a content item if your page should be treated as content - e.g. administrators can create, edit, publish, unpublish, and finally delete your page.
If you just want to create a simple page, then there is nothing to stop you from creating your own ASP MVC controller. You can define routes for it using Orchard's routing, and if you decorate it with a [Themed] attribute, it will even inherit the site's theme.

Passing parameters through sharepoint sitepage to web part

So I'm building sharepoint pages that are consisted of web parts. I need to send parameter to a page, and that send it further to these web parts, and I have no idea how to do this...
OOTB way:
You can use query string filter web part to capture the query string values and pass it to the web parts.

Custom WebParts:
You can use the following code snippet to capture the query string.
Request.QueryString["param"]

UpdatePanel in SharePoint throws an error

I get the following when I click on a custom made webpart in the Web Part Gallery: The control with ID 'UpdatePanel1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it. If I use the webpart, ie perform a search, I get a pop-up error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The Status code returned from the server was: 500.
This webpart takes a search string from a textbox, passes it to BL/DAL and returns a data from DB. I've integrated an UpdatePanel for partial postbacks - used this blog as guide but it is not working.
I've added the scriptManager to the default.master page using MSSP Designer as the blog suggests but curiously, the script manager causes an error (red underline) In Internet Explorer 6.0 the tag <asp:ScriptManager> is not permitted.
I'm not totally sure what's up with that but here's an alternative. Dont use MS Ajax - EVER. jQuery is simpler, faster, better, stronger, sexier!
This is how I normally do this stuff:
add jQuery to your master page head
create a user control that implements your web part ui. This should use Page.ScriptManager.RegistryScriptInclude or .RegistryScriptBlock to insert script for the control. Eg, methods to do your callback using jQuery.Ajax.
create a web part wrapper for the user control
create an aspx in _layouts that acts as the 'service' for your callback. The page load can use the parameters passed from the ajax call to return some json or text
Instead of #4 you could create a web service but this is a lot harder with SharePoint - an apx will work well enough.

connecting web parts in sharepoint

I am trying to connect to simple webparts in my sharepoint team site, i need one of the webparts to filter its information based on what it recieves from another webpart
I am using the query string filter webpart and the a list view webpart but no matter how i connect them always i am getting this error
"Web Part Error: This page has exceeded its data fetch limit for connected Web Parts. Try disconnecting one or more Web Parts to correct the problem."
What should I do and what am I doing wrong
update:
i can connect to web parts on some other pgae, but getting this error on the DispForm.aspx page of a certain item , is webpart connections not allowed there ??!!
There is an issue with creating QueryString filter webparts in sharepoint, when you're not using the Web UI (I'm making an assumption that you aren't).
This fella here has a post about it and how he hacked around the issue.

Another option is not using the QueryString filter web part at all, and just passing querystrings to a regular web part.

Me too,you look this url
http://blogs.msdn.com/sharepointdesigner/archive/2008/03/26/sharepoint-conference-building-a-sharepoint-designer-mashup-part-1.aspx
I have fixed this issue.
Problem
In the sharepoint list, filtered column name in query strng fitlter has been deleted and added new column with same name.
Solution: Remove filter and Set current view again in webpart properties. It works fine.

The page 'DispForm.aspx' usually is a form of a SharePoint list and different rules apply to list-form pages than on pages that do not belong to a Sharepoint list (and the differences are hardly documented). I solved the problem by workarounds; you could use not a ListViewWebPart, but a DataViewWebPart (Using Query String and Data view WebPart), or you could avoid the QueryStringFilterWebPart by using URL parameters that the ListViewWebPart understands (ListViewWebPart Filter Param).
