Web Forms :: Removing Existing JavaScript And Replace With Code?
Apr 12, 2010
In ASP.NET 4.0 RC2 the Menu Control by default emits Javascript like this:
[Code]....
There should be a feature coming up to disable this, but I think it's not in RC yet. At least it's not working for me.
Now, the problem is, that this Javascript kills my own Menu Javascript (I use an CSS Adapter). Is there a way to overwrite the stuff that comes from the Menu control? Can be a hack, just need something until this is fixed by MS.
I am receiving the contents of a file via ftp. I don't want to go into every detail (unless needed), but I am working with existing code that was using 3rd-party software to get ftp files. I am replacing that with .NET code. But I want to replace as little as possible of the existing code that is not specifically using the 3rd-party s/w. So I am trying to use a class originally written by the author of the code (a former employee).
This is his class constructor:
Code:
Public Sub New(ByVal fileName As String, ByVal content As StreamReader) Me.FileName = fileName Me.Content = content Me.TimeStamp = Date.Now End Sub
So I need to pass a StreamReader. My problem is how to get one. In my procedure ReceiveFile(), I execute this code:
Code:
Private Shared Sub ReceiveFile(ByVal sFilename As String, ByRef objMemoryStream As System.IO.MemoryStream) Try
Dim request As FtpWebRequest = DirectCast(WebRequest.Create("ftp site and folder" & sFilename), FtpWebRequest) request.Method = WebRequestMethods.Ftp.DownloadFile request.Credentials = New NetworkCredential("id", "pw") Dim response As FtpWebResponse = DirectCast(request.GetResponse(), FtpWebResponse) Dim responseStream As Stream = response.GetResponseStream() Dim reader As New StreamReader(responseStream) Dim sFile As String = reader.ReadToEnd 'reader.Close() ' response.Close() 'objMemoryStream = responseStream Dim objStream As System.IO.MemoryStream objStream = New System.IO.MemoryStream(Convert.FromBase64String(sFile)) ' objMemoryStream = Convert.FromBase64String(sFile) objMemoryStream = objStream 'Return reader Catch ex As Exception Dim i As Integer i = 10 End Try End Sub
responseStream is declared as a stream but when I query it in the debugger it says it's an FtpDataStream, after it's set equal to response.GetResponseStream. I want to take that stream and somehow get it into a MemoryStream. I thought I found the solution this morning via Convert.FromBase64String, but when I ran I got an exception saying "Invalid character in a base-64 string", and I think it's because of the newline character in the string. The file that's received contains three lines separated by a newline character.
I am working with a few .Net 4.0 webforms controls such as the Menu control and while I think it's great that I can now declare the way in which controls are rendered (i.e. as either tables or divs), I can't switch off the automagically-included javascript that manages the hover events for those controls, for example:new Sys.WebForms.Menu({ element: 'NavigationMenu', disappearAfter: 500, orientation: 'horizontal', tabIndex: 0, disabled: false }This appears at the bottom of every page that owns such a control.

I am developing an ASP.NET web page with C#. I have a sitemap document but I want to hide certain nodes based on the user's credentials. However, I am having problems with my code removing the actual node. Visual Studio runs the program with no errors. However, the node is still there. Below is the code I have developed for this. The node changes text to "it worked" as I hope written. However, it will not remove itself. I can get the item to be disabled, change enablement, but I need to hide it completely from the viewers view - not the document.
I tried putting a html replace code into a string which is then placed into a drop down menu. Only problem is it still appears as ² instead of a small 2.

It is not feasible to use ScriptManager.RegisterClientScriptBlock because script is around 200 to 300 of lines and also not feasible to move it in another JS File and Use ScriptManager.RegisterClientScriptInclude since each page has different script with almost same numbers of line Is there any way so that i can use existing script with minimum number of steps with full reusability

So I have a dropdown setup on the page called ddlVehicleType that is populated from a store. This method gets called when another dropdown is changed, and it's supposed to remove all items from the aforementioned store, re-add them as needed, and then populate the dropdown with the new values. It's doing everything it's supposed to EXCEPT clearing the store before it re-adds the values, so the result is, when I switch, I'm getting what it used to be PLUS the new values that should be in there by themselves. Here is the weird thing though, when I switch back, the values are removed without re-adding anything. Can anyone tell me what I'm doing wrong? Method is below:
function filterVehicleTypes() { var masterStore = Global.getComponent("vehicleTypeStore").getStore(); var Source = Global.getComponent("ddlValuationSource").getRawValue(); var isIncuded = ''; var IncludeFlags = ''; if (Source == undefined || Source == null) Source = ''; Global.getComponent("ddlVehicleType").getStore().removeAll(false); masterStore.each(function(rec) { switch (Source.toUpperCase()) { case 'KBB': if (rec.get('Code') == 'KBB') { Global.getComponent("ddlVehicleType").store.add(rec); } case 'NADA': IncludeFlags = rec.get('MiscCode1'); if (IncludeFlags != null) { isIncuded = IncludeFlags.substr(1, 1); if (isIncuded == 'Y' && rec.get('Code') == 'NADA') { Global.getComponent("ddlVehicleType").store.add(rec); } } break; default: IncludeFlags = rec.get('MiscCode1'); if (IncludeFlags != null) { isIncuded = IncludeFlags.substr(0, 1); if (isIncuded == 'Y') { Global.getComponent("ddlVehicleType").store.add(rec); } } break; } }); }

I have a multiline textbox that by default, is set to ReadOnly. I would like a button on the page to change the control to allow it to be edited. I would like this code to run on the client side because the page renders slowly and I'd like to avoid the post back.
The problem I'm having is the javascript code that I wrote to remove the readonly attribute appears to have no effect. I posted a stripped down example that illustrates the problem for your review.

i am new to ASP.NET. I am just now learning about all the benefits. I currently have some C# code that receives sensor signals such as distances from a robot and I wish to put that code into web services and into a website, so that if I want to gather some information from the robot i can through the web, as well as send signals back. I haven't found any information yet on how to do this.
