Web Forms :: Serializing The Value From A Textbox In Aspx.cs File To JavaScript Code?
Feb 19, 2011I have a list in a textbox in aspx.cs file and I want to pass it in the javascript code in the second web form.
View 12 RepliesI have a list in a textbox in aspx.cs file and I want to pass it in the javascript code in the second web form.
View 12 RepliesI have a web form where I create an array of type structure.
In this form I have:
[code]....
but this is not OK.
I have the following code:
<script type="text/javascript">
var checksSinceLastPostBack = new Array();
function clientSelectedIndexChanged(sender, eventArgs) {
var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");
var serializedCheckData = checksSinceLastPostBack.serializeArray();
if (ajaxManager != null)
ajaxManager.ajaxRequest(serializedCheckData);
}
</script>
The
var serializedCheckData = checksSinceLastPostBack.serializeArray();
doesn't seem to work. Am I misunderstanding this?
Also if this works, how would I deserialize it in the code behind?
A have a custom object - Person in my cs-file and I want to Bind the property Firstname from Person to my textbox txtFirstname in my aspx-file but I cant seem to make it work.
I usually work with webcontrols so its very rare that I get out of my cs-file and use the aspx-file. I can solve my problem by letting my cs-file update the Text-property on my TextBox - but I dont want that I have declared my Person object as protected in my cs-file like this
protected Person myPerson = new Person { Firstname = "Testname" }; and my aspx-file looks like this
<asp:TextBox ID="txtFirstname" runat="server" Text='<%# Bind("myPerson.Firstname")%>'></asp:TextBox>
I get nothing in my textbox and I want to use this method to update the text-property for a change - you know just to learn some new and not getting stocked in the cs-file all the time.
I am working solo on an Asp.net/C# project created by someone in the past. I created two new web forms, and then built the prjocect and did the deploy using a TFS team build project. For some strange reason, my Aspx file is not getting copied to the destination DEV server. It does get copied to a temp folder on that server, but in the end, the team build is failing and not copying over the new Aspx file.
So until I figure out how to fix the team build script, is their a way to just copy the Aspx file out to the desired server location? That as well as copying out a dll which is associated with the build file?

View 8 RepliesThe code I have entered below works fine in an .aspx file, however when I seperate the C# code into an aspx.cs file I get the red underlining for both 'UserAccountWizard' and 'RegisterPatientWizard'.

View 3 Replies.aspx file that I would have never even thought to look. It was occuring because of a control(ListView I believe) that had been "completely" commented out using the <!-- --> tags. The text was all green which gave me the re-assuring feeling that this code would not be included in the website. I finally decided to search my entire .aspx page for any occurences of the variable it kept insisting couldn't be "databound" and sure enough it was inside a template of a ListView control that was commented out.

I have code that needs to run in two deployments. Let's call them deployment H and deployment W.
The code is already running in deployment H, and there's an aspx page and an aspx.cs code-behind file. The code is compiled for framework 2.0 which is the lowest common denominator of the two deployments. Deployment H has its own logos and styling which are coded in its aspx file.
Deployment W now wants to use this same page, but it wants its own logos and styling. There are also additional fields on the page that deployment H doesn't need.
I think it's easier to maintain one code base which is why I want the same code-behind file, but I am having trouble figuring out how to set this up in Visual Studio. Orginally, I was going to have two projects, one for W and one for H, but I'd have to make the same changes to both files when some of the common areas changes.

How do i add my javascript file as an embeded resource to the page after the ajax javascript already on the page? NB want to do this part dynamically to have code wrapped up in usercontrol.
in aspx page: scriptmanager
Code: Assembly: WebResource("Functions.js", "text/javascript")
Code: onPreRender:
ScriptManager.RegisterClientScriptResource(Me.Page, Me.GetType().BaseType, "Functions.js")
This code successfully adds my javascript code to the page but not after the AJAX javascript and so not all of my functions work correctly.
I want to use authntication which apparently only work on folders. Thus, I wanted to move the Default.asp file into a new folder that I created. When I tried doing this by cut and paste I ran into problems. I changed the reference in the first line of the aspx file "Page" but the code behind VB file no longer sees the aspx page. In other words, the reference to contorls like Listbox1 show up being undeclared.
Is there a way to move the Default file and the related code behind file to a folder so everything works?
We have encountered this difference in file creation while using a HttpHandler Versus a Code Behind Aspx page. We are reading a saved jpg/png picture as byte array from a 'Image' field in sql server database and create a physical file in the server. Both the Aspx Page and Httphandler use the same code pasted below.
//Begin
int docID = Convert.ToInt32(Request.QueryString["DocID"]);
var docRow = documentDB.GetDocument(docID);
// Retrieve the physical directory path for the Uploads subdirectory
string destDir = Server.MapPath("../../Uploads").ToString() + "\";
string strFileName = destDir + DateTime.Now.ToFileTime() + "_" + docRow.DocName.ToString();
FileStream fs = new FileStream(strFileName, FileMode.CreateNew, FileAccess.Write);
fs.Write(docRow.DocData, 0, docRow.DocData.Length);
fs.Flush();
fs.Close();
// End
After the file is created, it is viewable as a jpg/png Image only in Aspx Code Behind. While in case of HttpHandler it is not a valid Image.
First i created the TimeSheet.aspx file,then added code files names TimeSheet.aspx.cs file. created a TimeSheet class and code some code in that ,later in the @page directive added the codebehind attibute with value "TimeSheet.aspx.cs" and inherits attribute with value TimeSheet. Now i want to make this code behind file to show up as a sub-branch of TimeSheetp.aspx.Just like a designer file.
Like
TimeSheet.aspx
|----TimeSheet.aspx.cs
how will i do that?
I have a system that has several large objects that need to be built and populated each and every time, and these objects may be accessed quite often as well. As a strategy, caching would not be that good for me because there are potentially thousands of these objects which are fairly large. So I propose to serialize the objects to the file system and then deserialize it when I need those objects again. I have several classes that need this serialization functionality.
These objects change as well, so on the next access I check if there were any changes and then I grab only the changes and edit the object, and then reserialize the object.
My question is what is the best way to do this, since I have several classes ..
How i prevent "inline code" in .aspx or .ascx file like sharepoint "Code blocks are not allowed in this file"
View 1 RepliesIs there a way i can access a certain textbox in the .asps.cs file code?
I have an insert statement where i have a textbox like so for example:
PHP Code:
<asp:TextBox ID="txt_title" runat="server"</asp:TextBox>
And then in the backend i access it like to txt_title.Text;
This is fine. However i have a calendar popup which is shown:
PHP Code:
[code]....
A calendar popup appears when i click on the button. Now i need to insert the textbox value in the database but i cant seem to get access to it in the .cs file. I have tried adding runat="server" but it then stops the popup from working.
The inline code
<% for (int i = 0; i < ThumbnailList.Items.Count; i++)
{ Response.Write("thumbnailViews[" + i.ToString() + "] = $find('" +
ThumbnailList.Items[i].FindControl("ThumbnailView").ClientID + "');
"); } %>
produces a bunch of compile time errors in Visual Studio 2008 - although it works fine.
But this seems to be the exact way inline code should be added, at least according to this MS help file:
[URL]
The errors are:
expected expression (at "<%")
expected ';' (at "int i")
expected ')' (at ThumbnailList.Items.Count;
expected ';' (at " i++)")
I have done a
<%@ Page Language="C#" ...
at the top of the file.
I can't get my .aspx page to recognize control events in it's codebehind.

which is fine, but I don't want to use inline script.
