I need to programmatically parse and transform ASP.NET webform pages. It's a requirement that I have =(.
Anyone know any tools or frameworks?
Update:
I just need to modify ASPX pages (not rendered HTML code).
There are no inline c# code.
I would like to know which CODE, Classes could be useful for creating a WEB APPLICATION that could:
01 - Connect to an HTML file on the web.
02 - Parse its content (text content).
03 - Find out specific content in a page (for example looking for specific keywords).
Also how to implement:
04 - How to submit information programmatically in HTML page (feeling forms).
I am interested in understanding Classes and general practice and CODE for accomplish this task.
I've created a wallboard application to display outstanding support calls for my ICT department. I've bound a number of gridviews to sqldatasources which execute a stored procedure. This is automated via asp.net ajax controls and partially refreshes the page/data every 30 seconds.
At the moment, when the number of records in the gridview goes over 9, the gridview automatically pages and shows the number of pages in the bottom right hand corner. The helpdesk can then VNC to the box which controls the screen and manually click to see what's on the next page.
What I am after is a way to programmatically (using the c# code-behind file) changing the current displayed page after 10/15 seconds or so, obviously if this is possible in the scope of the gridview. I trailed using javascript (and failed at jquery) of scrolling the gridview within a div, however this didn't work as expected.
Can anyone point me in the right example. I can't find anyone else querying this functionality via a quick Google.
Gridview Code:
<asp:GridView ID="GridView1" ShowHeader="False" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"
GridLines="None" CellPadding="2" Font-Size="35pt" AllowPaging="True" PageSize="9">
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" SortExpression="ID">
<ItemStyle Width="15%" />
</asp:BoundField>
<asp:BoundField DataField="ASSIGNEES" HeaderText="ASSIGNEES" SortExpression="ASSIGNEES">
<ItemStyle Width="32%" Wrap="false"/>
</asp:BoundField>
<asp:BoundField DataField="title" HeaderText="title" SortExpression="title">
<ItemStyle Width="53%" Wrap="false"/>
</asp:BoundField>
</Columns>
</asp:GridView>
SqlDataSource Code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FPConnectionString %>" SelectCommand="HDMonitoringOutstandingToday" SelectCommandType="StoredProcedure"></asp:SqlDataSource>

Apropos MSDN link: [URL] [.NET Framework 4 - ASP.NET] Implementing Client Callbacks Programmatically Without Postbacks in ASP.NET Web Pages Using the code from the above link in the following code snippet, if you keep a break point on the statement "if (IsPostBack)" in the Page_Load event. The control moves into the "if (IsPostBack)" block after the alert, which mean that it is a Postback. Then, how come you say "...Without Postbacks"? I am getting confused here.

What I want is that I can add /edit or delete view pages. I don't want a complex content management system , just looking for any examples where one can add simple view page, I have no idea how to add action result dynamically, programatically on a controller page in mvc2.
View 5 RepliesI am a total novice to VB so bear with me.In my web-based project, I pass an ID field as a parameter in my URL and go through each row in my gridview to find the correct row that matches the ID parameter, like so:
[Code]....
[Code]....
The problem is that this code only works if the corresponding ID is in a row displayed on the first page. I want to loop through each page in the gridview's rows until either the correct ID is found or it reaches the end of the data set. How do I do this? I assume I need another For loop that looks something like...
[Code]....
...that will go right before my other for loop, and one will loop through each page in the gridview. But obviously I've got that For Loop completely wrong. How do I do this correctly?
I mean, it's easy to add a Button programmactically to an aspx page, but a server control's event handler probably has to be set early in the page life cycle (maybe before Control.Load event). As a result in reality, are dynamic controls rarely added to apsx pages?I wish there is a way to call postback at the server, so that a event is never too late.
View 2 RepliesI am using a server control on a single web.forms page. I have to use this control on a web.forms page since its a server control, although this is actually a MVC project. So I created a web.forms folder and put my new page in it. I then copy the example code from the signature control. I get the following error:
The base class includes the field 'ctrlSign', but its type (WebSignatureCapture.SignatureControl) is not compatible with the type of control (ASP.signaturecapture_signaturecontrol_ctlsignature_ascx).
I know the code works because if I removed the ID attribute from the server control, it no longer gives me this error and my control renders. But I need the attribute for the ID so I can perform is post event
I am using this signature control. Here's the web.forms code...
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Index.aspx.cs" Inherits="KahunaCentralTIDRevamp.SignatureCapture.Index" %> [code]....
I am using ASP.NET 2.0 on IIS6 therefore I can't use system.web.routing. I've tried a few URL rewriters but none did what I wanted.I basically need to transform (read/parse then redirect) URL 1 into 2 with minimum IIS configuration because I don't have the full authority to reconfigure web servers (i.e. ISAP on IIS6 or install 3rd party extensions/libraries). And I can't transform URL into 3 because all the physical links will break. [URL]
View 3 Repliesi am new with linq and i wanna do something like this in linq:

how can i do this?
i have the xml in a structure such as this:
<RWFCriteria reportType="ProgramReview">
<item id="36" name="" value="9" type="Milestone" />
<item id="31" name="" value="9" type="Milestone" />
<item id="33" name="" value="11" type="Milestone" />
</RWFCriteria>
in webform 1, i have search button when i click its open webform2 and there the gridview.
I want when i click the link in gridview in webform 2 then it close webform 2 and change the datasource parameter in webform 1 without open the new window (still same window)
What is right way to send visitors from one webform to other. What are their limitations and their plus points.

View 4 RepliesI want to use the web.config transformation that works fine for publish also for debugging.When i publish a web app, visual studio automatically transforms the web.config based on my currenc build configuration.How can i tell visual studio to do the same when i start debugging.On debug start it simply uses the default web.config without transformation.
View 5 RepliesI have easy to reproduce issue with web.config transform. Steps below are causing major grief.
Create new Web Application Project in VS 2010. Open web.debug.config, put following inside it
<?xml version="1.0"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform" xdt:Transform ="Replace">
<applicationSettings>
<MyProject.Properties.Settings>
<setting name="Username" serializeAs="String">
<value>username</value>
</setting>
</MyProject.Properties.Settings>
</applicationSettings>
</configuration>
Now deploy to file system on local hardrive. Open resulting web.config and see <value> setting has extrac carriag return and bunch of tabs in front of it..

I've got a data table with columns in which include Item, Category and Value (and others, but those are the only relevant ones for this problem) that I access via LINQ in a C# ASP.Net MVC app. I want to transform these into a matrix and output that as a CSV file to pull into Excel as matrix with the items down the side, the categories across the top and the values in the row cells. However, I don't know how many, or what, categories there will be in this table, nor will there always be a record for each item/category combination.
I've written this by looping round, getting my "master category" list, then looking again for each item, filling in either blank or Value, depending on whether the item/category record exists, but as there are currently 27000 records in the table, this isn't as fast as I'd like. Is there a slicker and faster way I can do this, maybe via LINQ (firing into a quicker SQL statement so the DB server can do the leg-work), or will any method essentially come back to what I am doing?
What are the steps to execute the task above? the reason I want to do that now is because the web site is ready for deployment and
we would like to deliver it as a DLL. I've heard of [aspnet_merge.exe] but I want to ofuscate my code with a 3rd party tool; and this ofuscator tool only works with Project-based projects.
I want to transfer data from datatable to a gridview with a hyperlink column. But dont know how to do.
I attach my code as below, what i want to do is to output 2 columns in gridview, and the first column should be a hyperlink. However, now the first column still shows nothing.

I have a page with an panel on it that can contain a number of editable controls (textboxes, date pickers etc). This panel (and the controls) are populated dynamicaly by loading up an XSLT tranformation and applying it to an XML document (which represents the entity being edited) in the Pages Load event if !isPostBack.
Once the user has made changes they click a button and the form posts back. At that point I want to be able to go through the various controls in the panel, get the updated values and persist them back to a database. When I try to access the controls in the underlying buttons even theyre not there the panel is empty.
What I think is happening is that the page is being recreated at the start of the post back. When its recreated the XSLT transformation doesnt run because its a postback so the edit panel never gets repopulated. The controls therefore dont exist as far as my Button handler is concerned and it cant access their values.
My stopgap solution to this is that Im not checking isPostBack before repopulating the panel, so now the panel gets repopulated in the post back, the controls are there and Im able to query their values. The problem is that this involves another round trip to the database server to pick up the xslt and thats undesirable.So, first of all, have I understood the problem correctly?
I could save the trip to the db by storing the xslt (probably in the view state) but the whole idea of having to load up the control before checking its values feels sort of wrong and Im concerned that Im doing the wrong thing without realising. When I repopulate the control I am, of course, applying the XSLT to the XML document as it stood before the user made any edits. I would have expected querying the value of a control to return me the value before the user changes, but it actually seems to return me the value of the control as it was in the page when the user clicked the button. How can that be?
I have installed VS2010 ultimate and have read with interest about the new publish options, config transformations but none of them are available. I have tried creating different release versions and cannot see the option, also have no new options for publish, just look like the VS2008 ones.
Is there some service pack or pack that i need to install these or does it sound like a reinstall?
Does anyone know if there is a way to "transform" specific sections of values instead of replacing the whole value or an attribute?
For example, I've got several appSettings entries that specify the Urls for different webservices. These entries are slightly different in the dev environment than the production environment. Some are less trivial than others

I have a question:
When I want to add "<br>" to a text of a gridview row to make it starts in a new line, but it doesn't work and I got the "<br>" in the view source of the IE.
we are trying to use google to get exchange rate prices.
they use a csv file which we get the code to go out and get.
what im trying to do is pick the first line of the file and just use that. i have the following code but its not just picking the one line.
