Here's my .aspx code.

"Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I'm more of a php guy, so this is a little over my head..
I have a DataList containing an ImageButton whose ImageUrl property I want to set by combining it with a string returned from a codebehind file property and a database value.
I have a protected property in my codebehind called strPath.
I want to combine it with a database value in my aspx file. Like so:

I've defined a session variable in my Session_Start procedure
void Session_Start(object sender, EventArgs e)
{
<other stuff>
string sAdmin= bAdmin.ToString();
Session["SessionAdmin"] = sAdmin;
}
Then in my masterpage I want to use the Session Variable to conditionally show some links in a list.
How do I write the Boolean expression to correctly access the session variable SessionAdmin?
Here's what I have:
<div id="menu">
<ul>
<li><a href="/EmployeeTime.aspx">Employee Time</a></li>
<% if ( *** a Boolean expression involving Session variable "SessionAdmin" *** ) {%>
<li><a href="/Employee.aspx">Employees</a></li>
<li><a href="/ProductLine.aspx">Product Lines</a></li>
<li><a href="/Task.aspx">Tasks</a></li>
<li><a href="/Type.aspx">Work Types</a></li>
<li><a href="/Activity.aspx">Activities</a></li>
<%} %>>
</ul>
</div>
How do I correctly define my boolean expression? I've been looking, but haven't found the right syntax.
I have a variable in an aspx file I need to use/recover it's value into an ascx web control that's in this aspx file. It's possible to do it? The aspx dynamically loads web controls depending the scenario, so this web control not allways is loaded.

In Datalist Item Template Another Datalist And Child Datalist How can we access link button inside chile datalist when click in child link button
View 1 RepliesI have to display data (names) in a random order on the website. The data is stored in a MS Access database. The names must be displayed in a GridView and DataList in different places. I have created a query in MS Access "zorder: Rnd([MarinaAccommodation]![ID])" which works fine in MS Access giving me a different order each time.
The problem is that when I try run it on the website the order remains the same, it does not change each time the page is loaded.
The problem is that i have a search page. Access Database holding the information. I have a Access Datasource on the page with a Datalist to show the data. I need to find a way on setting it up to says "Sorry no results found" when the is no results. i am unsure on how to do this though.
Below is my datasource and datalist
[Code]....
how to get the selected item in datalist? For eg, I'm displaying a list of food items in a datalist with food name, price, type, a button(Click to order). Now I wanted to click on the selected button and get that specific food name, price & etc from the datalist.
View 1 RepliesI had Datalist and I want to give item style when I click on it to show user the he select this item I did my code but when I selected item It didnot have any style
protected void DataList3_ItemDataBound(object sender, DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
e.Item.Attributes["onmouseover"] = "this.style.cursor='hand';this.style.textDecoration='underline';";
e.Item.Attributes["onmouseout"] = "this.style.textDecoration='none';";
e.Item.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.DataList3, "Select$" + e.Item.ItemIndex);
}
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 have to make report and print. how to print datalist each item in different page.
View 3 RepliesI have a Datalist and when a button is clicked I would like to send the values of the fields to a new page to fill some text boxes. What is the best way to do this. I had thought that since the DataList had itemtemplates that were labels I could reference them like regular labels ( str = Label1.text ). That isn't working. I was just going to send the values through a query string. Which I have an example of that, unless there is a better way.
View 3 RepliesI put common code in the app_code directory. I access classes in the code all the time from aspx.cs files by "using" the name space from the C# file in app_code and then referencing the class. Now I want to access a class from an app_code file a aspx file. How do I do this?
View 8 RepliesI want to set my DataList control to have only 7 items visible in each column after DataBind.Let's say' if I have 18 items in the data source; DataList should be rendered as 3 colums.
1st column will have first 7 items.
2nd column will have items from 8 to 15
3rd column will have items from 16 to 18
How can I set the item count per column for each itemTemplate?
I have the following DataList control:

When I click on the LinkButton, I want to insert the current item in the DataList into the database via LINQ to SQL in C# code behind. In the codeb behind, how do I retrieve that particular item so I can insert it into the database?
I have a datalist control which is filtered through a query string select parameter for a single product each time
This is on a details page What i want is to dynamically set the page's title according to the selected product's name Something like..... Page Title="<%# Eval("Title") %>"..... but that of cource won't work
I'm using C# for my code behind
I'm creating a forum and the forum posts are items in a datalist.
Now I want to include the nifty feature that when one has replied to a message and the forum thread page is being displayed, the page is autmatically scrolled down to the message one wrote (the same thing goes for linking to a message, one wants the page to be scrolled down to the right place from the start).
I guess this could be done using anchors an html, but is there a function i vb.net that would do this for me?
I'm trying to do something what I thought was simple: Attach a local click event to a DataList item. Yet I can't get it to work.
To make things simplest for everyone to understand I've created this sample little project.
I have a datalist, and on the ItemTemplate, I do this for example:
<%#Eval ("MinAge") %>
Where MinAge is a Int. I also have a MaxAge that is also an int.
Quesiton is, how do i change it so that i could do something like:
if (MaxAge == 99)
MinAge + "+"
else
MinAge + "-" + MaxAge
so that if we have minage=18,maxage=99 it will be 18+ if we have minage=18,maxage=20 it will be 18 - 20
the thing is it gets complicated for me because i try to change int to string, so what is the proper way of doing it?
I have one datalist,in datalist one column is UserName and in second column one button i.e. Delete. When I click on Delete then delete the this row from datalist.how to create this functionality.
View 1 Repliesfirst off I can't post the code, so I will do my best to try to explain what I am trying to do. I have a repeater with three literals (a member ID, a name, a uservalue) and three hyperlinks. Each of the hyperlinks goes to a different page (obviously).What I am trying to do is when the user clicks on one of the hyperlinks, (doesn't matter which one because the three literals need to be put into session variables regardless) I want the session variables set to the literal values before calling the next page.How do I get the session variables set when the user clicks on one of the hyperlinks?
