In ASP.NET 4.0, I have an IHttpModule that apply a filter on HttpRequest.Filter. As the result, the content stream length is changed, and it breaks WCF with now returns 400 bad request because of the mismatch between the body length and the HTTP headers.
View 1 Repliesi am pulling data from database to the pdf file but i need to show those data in page by page. Here i am using iTextSharp for pdf. Is there any page break options. I did try document.NewPage(); But it didn't work out.
View 3 RepliesI have a rdl report for displaying letters. When the content of a letter is very long(say 8000 characters), naturally on printing it will be printed in multiple pages. But when I do a preview, all the content is shown in one page only with vertical scrollbars. Can I have a page break here, so that I know the amount of pages my letter is going to consume on printing.?
View 1 RepliesI am trying to add a validation of the textbox.text.length in a FormView and prevent the insertion of being made in case the text length is not compliant (less than four characters).
In the scenario when clicking the submit button an Alert should appear with xxxx warinig text. and the Insert command being prevented.
This is my FormView Insert Template:

Let's say I have an abstract class IA, with subclasses A1, A2, A3.For each subclass, I had a page with a FormView to insert/edit/view, with code specific to that class. The templates for insert/edit/view are all very similar, so it was mostly cut & paste, and the compiler had no problem that there were controls with the same IDs in the different templates.Something like this:
<asp:FormView>
<InsertItemTemplate>
<asp:Label id="Label1" />

I have a two-character field for US State. I add a RegularExpressionValidator control to validate the input using
ValidationExpression="[a-zA-Z]{2}"which works to validate the content when something's entered, but it doesn't catch if someone just leaves the textbox blank.
Is there any way to validate within the same regex to catch an empty textbox?
I am exporting a HTML table to excel by sending the data as a HTML Table string and setting the content headers:

Is there a simple way of setting the content-length based on the size of the HTML string? Or should I just leave it blank anyway...would be nice to have the content-length ideally...
I have an asp.net web page to serve large file downloads to users.
The page is hosted on IIS7, Windows Server 2008.
The strange thing is that users can download at good speeds (2MB/s) when I don't add a content-length response header but as soon as I add this header, download speed drops to somewhere around 35kbps/s.
This is the code:

Of course I can leave the content-length out but the user will not know how big the file is and how long the download will take...which is annoying.
I have repeator control that is bind to a datareader.

What i want is to display 100 characters from it, along with more href link at the end.

One of my apps is to document aircraft inspection at mil sites. The discrepancy report for any one tail number can be many pages long. The description of the discrepancy in a gridview cell can be several lines. Therefore when the gridview hits the bottom of the physical page, the print spooler frequently splits the gridview row leaving part on one page and the rest at the top of the following page. I have done my due-diligence in research before posting but maybe I'm using the wrong words. I found something on CodeProject but it is too complicated for me. Does anyone have a simple solution? I use C# and am not very sharp with Java script.
View 6 RepliesI need to set the pager settings of an ASP GridView to look just like this:
********************************************************************** ******************************************
********************************************************************** ******************************************
Showing 31 - 40 of 500 items Page:<12345678910>
I have edited and tweaked so many attributes, but I have gotten confused. Here is the GridView header as I have it now:
HTML Code:
<asp:GridView ID="OrdersGridView" runat="server"
AllowPaging="True" AllowSorting="True" PageSize="25"
AutoGenerateColumns="False" width="100%"
CssClass="mGrid" PagerStyle-CssClass="paging" AlternatingRowStyle-CssClass="alt" PagerSettings-PageButtonCount="20" ShowFooter="True"
[Code] .....
That gives me the following look:
********************************************************************************** **********************************************
********************************************************************************** **********************************************
I still do not know how to get the records count and things over to the left on the same line. I have them down on my footer in the DataRowBound routine.
The first image I posted in the picture of what I want it to look like, the behavior of the < and the > brackets is to go to the next page not jump to the front or back or anything else.
Is it possible to edit the content of a view from a action filter.
What I am working on is a Resourcemanager that I can use to manage
my style sheets, js and other resources. I want to be able to put
lines in the the view any where like Html.ResourceManager.AddScriptFile("MyScript")
or Html.ResourceManager.AddCSSFile("MyCSS")
and at the end of the view call Html.Render(); this would then place the content of my resources at this point. My problem is that I want to put the CSS stuff at the top of the view, but them problem is that it is renderend at the end of the view, so I tought that I could use a ActionFilter to move it to the top of the view.
1) What would be the best way to do this task ?
2) Is there any resources that describe the way that the MVC framework works in more detail ?
I have several functions running on a postback that can take a little time to complete.
When postback is initiated I show a loading image with this code:
function showLoader()
{
document.getElementById("<%=loadingImage.ClientID%>").style.visibility="visible";
}
I want to be able to add code to this function so if user tries to leave at this point they are informed the operation is not complete.
[code]....
how I can tweak to just show when user leaves page and not when postback completes?
I'm creating a RDLC report in C#. Is it possible to insert the content of a Word 2003 document (with formatting) in it (either in design time or programmatically) before exporting to PDF. The final result will be a PDF file containing the initial report (fields from database) and the Word document content following it.
Why this? I need to give the user the possibility to fill a form, attach a word document and export the all to PDF as I described earlier (ASP.NET). I don't have Word installed on the server so I can't Interact with its COM objects.

With dgBookings
.AllowPaging = True
.PagerStyle.Mode = PagerMode.NumericPages
.PagerStyle.PageButtonCount = 5

End With
Is there a way to set the horizontal-align in the code too I tried adding this
.PagerStyle.HorizontalAlign = Right
and I get this errorArgument not specified for parameter 'Length' of 'Public Function Right(str As String, Length As Integer) As String'.
All implementation of IHttpModule I've seen looks following:
[code]....
I am wondering why is the Dispose method always empty? Shouldn't we unsubscribe the event which we subscribe in the Init method?
I've declared an event on an HTTP Module so it will poll subscribers for a true/false value to determine if it should go ahead with its task of tweaking the HTTP Response. If only one subscriber answers true then it runs its logic.
Are there potential pitfalls I'm not seeing?
public class ResponseTweaker : IHttpModule {
// to be a list of subscribers
List<Func<HttpApplication, bool>> listRespondants = new List<Func<HttpApplication, bool>>();
// event that stores its subscribers in a collection
public event Func<HttpApplication, bool> RequestConfirmation {
[Code]....
Is it possible filtering a list in a content page by a value set in its master page? I mean when a user clicks on a link button in master page a variable is set and then based on the value that variable, when loading a content page, a list in it is filtered?
View 1 RepliesWhat is the difference between HttpApplication class and IHttpModule? Are they both same or different?
I see articles that mention the same events in both the classes.
An IHttpModule implementation I created
public class ResponseTweaker : IHttpModule { // my module ...
is registered in Web.config
<system.web>
<httpModules>
<add name="redman" type="ResponseTweaker"/>
</httpModules>
and an instance of it is sitting in the pipeline.
From the perspective of a caller (e.g. from the Global.asax.cs file), how should I get a reference to that module instance?
public class NHibernateSessionPerRequest<T>:IHttpModule
{
public void Dispose() { }
public void Init(HttpApplication context)
{
context.BeginRequest += BeginRequest;
context.EndRequest += EndRequest;
}
}
How can it be registered in web.config?
