I have a listview control on an .aspx page. Inside this list view i want to check "Type" property which comes from database. here is the example code :
[code]...
As a last resort i tried to user DataBinder.Eval() but i get the exception "Expected class, delegate, enum, interface, or struct". What can i be doing wrong? Writing a function in code-behind isn't an option for me.
where I show a link if value>0 .. However it gives me a bad url(history.aspx?visitorid=%3C%#%20Eval) when I put visitorID=<%#...%>inside another Eval<%#..%>
What I'm trying to do is if the "Name" column is empty then bind to "Other" column, otherwise bind to "Name" column. Anyone know the right syntax, keep getting object not set to reference. I'm doing this in VB.Net.
if you have two table inner join like SELECT* From A INNER JOIN B on A.ID = B.IDSay A and B tables both have Username values but A's username is Test, and B's username is Test2When I do Eval("Username") it always print out "Test", how can I configure it to print out "Test2"... meaning how to specify which table's value to put using eval.. is there something like Eval(B.("Username"))??
What I am trying to achieve is to use an Eval as parameter in my anchor tag's href. The anchor is nested inside a repeater, why I cannot use the code behind to achieve this.
but an error occurred in the javascript Error Console in Mozilla browser. Error: missing ) after argument list Source File: javascript:NavigateUrl("<%#Eval("TicketID")%>","<%=RedirectURL%20%>"); Line: 1, Column: 22 Source Code: NavigateUrl("<%#Eval("TicketID")%>","<%=RedirectURL %>");
I want to remove the error. but functionality is ok.
When creating a website using Asp.Net and using controls such as the ListView is it good practice to use the "Eval" command or should there be a literal and the data populated in the databind event?
Code: <asp:Label ID="lblName" runat="server" Text='<%# Eval("Title")%> <%# Eval("Forename")%> <%# Eval("Surname")%>' ></asp:Label> And what is the best way to achive this?
I want to know where lies the difference between these two.I had a google search on this topic and a lots of replies and each of them tell the same thing:
Eval means one way binding(i.e;readonly) Bind means two way binding(i.e;both read as well as write the datasource)
but none of them explained it more clearly.all i want to know is how can i use the Bind to update/insert something from the datasource?
I've a asp.net linkbutton inside asp.net repeater control which renders multiple link buttons. I want to set the style of each and every linkbutton dynamically.
I have a SQLDataSource that is bound to a ListView control but I want to place parts of the bound record into the HTML TITLE attribute. Here is my codebehind file that I want to change so it can use Eval to construct a dynamic TITLE based on the data content:
I am working on my first project with the Entity Framework and am having some difficulty displaying advanced information with the EntityDataSource and a ListView.
For example, given the two entities:
Item Name Price Order Number Items <---- Navigation Property to Items contained in the Order
I want to display a list of all orders with a column with the total number of items in the order and a column with the sum of the prices of all items in the order.
I am using an EntityDataSource configured as follows:
In the ItemTemplate of the ListView, I can write the order number as follows:
<%# Eval("Number") %>
I had trouble figuring out how to display a count of items in the order. I tried using Items.Count() function in select statement in the EntityDataSource but that didn't work. Eventually I figured out I could do the following in my ItemTemplate:
<%# Eval("Items").Count() %>
Now I am stuck trying to get the sum of the items. I am stuck here. I have tried using
<%# Eval("Items").Sum(Function(i) i.Price)%>
but I get the following error:
Public member 'Sum' on type 'EntityCollection(Of Item)' not found.
This confuses me because I know that Sum is a method of EntityCollection(Of ).
My two questions are as follows:
Am I getting the item count correctly?
How should I go about getting the sum of the prices of the items?
I have two images progress.png and completed.png. Depending on the status in the db table (In Progress of Complete), I want to display the appropriate image. What is the correct syntax for the IIF() statement within asp.net?
pseudocode:
<asp:image ImageUrl='<%# IIF(Eval("Status").Equals("In Progress") display - 'images/progress.png') else if status equals "Complete" display - 'images/complete.png' %>' />
I have a gridview and the OnRowDataBound event is linked to this function:
if (e.Row.RowType == DataControlRowType.DataRow) { ThisRow = e.Row.DataItem as MyObjectModel; if (ThisRow.Property1 == null) { e.Row.Cells[5].Text = "-"; }
This code looks at the value of a property of the object in the data source and if it's null, converts the null to display "-" in column 5. The problem I'm having is that if I change the order of the columns of the gridview, then I need to change the index of every other modification. What I'd like to do is change the statement "e.Row.Cells[5].Text" to something that says "the cell whose column header is xyz".
