Forms Data Controls :: Use Session Variable In Markup Aspx Page?
Sep 8, 2010
Is it possible to use a session variable in the markup aspx page ?
Cause I have a gridview that use an sqldatasource and in the UpdateCommand I want to include a the session variable : session("username").
Ex :
UpdateCommand="UPDATE departments SET DEP_name = @DEP_name, DEP_active = @DEP_active, DEP_date_stamp = CONVERT (CHAR(8), GETDATE(), 112) + ' ' + CONVERT (VARCHAR(8), GETDATE(), 108),
DEP_user_stamp = <% session("username") %> WHERE (DEP_mnc = @original_DEP_mnc)">
This give me an error :
Server tags cannot contain <% .... %> constructs.

I have created a web user control called Activity. I have defined a public-facing event on that web user control called OnActivityDelete. There is a delete button in the Activity control. When the delete button is clicked, the Activity control fires the OnActivityDelete event. I am using this web user control in a repeater. I assign an event handler to the OnActivityDelete event on the repeater's item data bound event. When I click the delete button for the Activity control, the event fires from the Activity control, but it never hits the event handler in the page that's using the control. (I have stepped into the code with the debugger and confirmed this behavior).
My suspicion is that this behavior has something to do with the fact that the event handlers are added in code behind when I bind the repeater to a datasource, which I only do if the page is not posting back.Is it possible to define the event handler for the Activity control in the markup of the aspx page? If so, will this solve my problem?If not, do I have to bind the repeater and hook up to the events every page load in order to solve my problem (this works, I just tested it), or is there some viewstate trick to getting the events to persist? Markup of Repeater on page:
<asp:Repeater ID="rptrActivites" runat="server" EnableViewState="true">
<ItemTemplate>
<div class="activity">[code]...
Page's code behind:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If Not Page.IsPostBack Then
GetActivities() [code]....

I have a page with 2 dropdown menus and 2 datagrids.
The datagrids get populated by a database based on a dropdown menu slection.
This page links to another page which in turn links back to the original.
If the user leaves the first page and then returns back I want to keep the dropdown menus and datagrids populated.
I tried doing this with session variables but can't get the datagrids to stay populated ...

A question from a non-web-designer about the preferred - and least browser-sensitive - way of shifting users controls a few pixels horizontally and vertically if I'm using divs instead of table cells.
If you look at this top part of a web page, you will notice that the lower menu is a couple of pixels too far to the left and a couple pixels too high. (Note right edge doesn't line up with the menu above it. Also, tops of image buttons to the right of the lower control are clipped.)
Can I position them absolutely, or use white space to shift the lower one into alignment?
Here's a screenshot:
Here is the approximate markup:
<body id="bodyTag" runat="server">
<form id="Form1" method="post" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<div id="divAll" runat="server" style="visibility:visible;">

I have dropdown and I have to bind that dropdown on the basis of user login so that when the page load the drop down should show only one item on the basis of user login and i may have use that dropdown item as a search parameter.I have a objectdatasource named TblFltReg having one of the fields named "Owner" which is the SectionId.
There is a table named TblSections having "SectionId" and "Description".User can be selected in a Session variable.I have another table "Users" having "UserName", "UProfile", "SectionId".Actually I dont know how can I get SectionId from Users table into Session variable.So I have two tasks: one to get SectionId into Session Variable and another is to show dropdown item on the basis of User login.Hope you understand.
How can I perform that task?

Currently in an .aspx file, I am storing a value (filename that was created in that session) in an hidden text box. When the user clicks on the "Print" labeled Hyperlink control, it opens the file that was stored in the hidden text box control. But when the user goes to different screen (in the same session), I loose the filename value that is stored in the hidden text box control. So I would like to store the filename variable in a session variable. So that if the user leaves this .aspx file and comes back to this .aspx file I can load the value into the hidden text box from the session variable.

I am using an asp.net/c# datalist.
<asp:DataList ID="EquipmentList" RepeatColumns="5".....
I have the following line inside the <ItemTemplate> tag:
<a href=""><%# {I want to put something here but dont know how} %> </a>
In my code behind I have a NameValueCollection variable that contains all strings:
NameValueCollection myListofStrings = //calling a method here that populates myListofStrings
this.EquipmentList.DataSource = myListofStrings;
this.EquipmentList.DataBind();
can someone tell me how to bind this NameValueCollection variable to my datalist tag in the markup? Also additional knowledge on how to bind a datalist to a dataset, sqldatareader, IList<>
but for now what do I write inside the tag if lets say i HAVE to bind to a NameValueCollection variable like in my case above. It has no properties or columns so I cannot write anything like Eval("propertyname") which is the answer that most here gave me. It is just like I am binding it to an array of strings. So what do I write now?

I am using ASP.NET..........
It is possible to create a session variable on page load just for a particular page/url?
The problem that I have is: The user comes to page 1 and the session variable becomes A, then he opens page 2 in a new tab and the session variable because B on both page 1 and page 2.
So when the user needs the session variable on page 1 it does not work because the variable have changed!

I'm new to ASP.NET and can't figure out how to accomplish this...My code (that needs fixing):
<asp:HyperLink runat="server"
NavigateUrl="~/EditReport.aspx?featureId=<%= featureId %>" />
featureId gets defined as an integer in the backing code. I want href's like...
/EditReport.aspx?featureId=2224
...but instead I am getting...
/EditReport.aspx?featureId=<%= featureId %>

I have an asp.net repeater control with a series of asp:hyperlink's
<asp:HyperLink runat="server" ID="name" NavigationUrl="~/Pages/display.aspx?fileid={0}&user={1}" />
and then on the OnItemDataBound method:
fullname.NavigationUrl=string.Format(name.NavigationUrl, user.fileid, user.userid);
So that gives me a series of URLs in the repeater:
[URL]
OK, so with a simple proxy tool someone can replace either of the parameters with some OTHER number to get access to what they shouldn't see.
server-side validation and authentication aside, is there a better method other than passing parameters when trying to create a dynamic URL within a repeater?
