I am using a DataList Control and with the Eval Bind below in the Item Template.
[code]....
I want to do is add a bracket each side of the "CountryName" so it displays as (Spain) for example.
I have a datalist and would like to add an if statement within the Text part of my label.
Tried the following but it doesn't work
Note: if I do a normal eval Text='<%# Eval("UI_successful_trans")%>' the value returned from the database will be 1 or 0. Depending of which value is returned, I would like to have the text "Win" or "Lose" returned. ( I know that this could easily be done in code behind but I would like to know if it is
possible to to do that inline ?
[Code]....
[Code]....
<asp:Label ID="lblsize" runat="server" Text='<%# Eval("size")%>' />
in the syntax above, what is '<%# Eval("size")%>' means?
How do I store an Eval in a variable or use the value of the Eval in an if statement?
View 5 RepliesI have a conditional Eval statement in a Gridview that returns a boolean result to display an image if two datafields(strings) are identical:
Visible='<%# Eval("customerA").Equals(Eval("customerB")) %>'
Works great except I don't want the image to display if both datafields are empty. How can I add that logic into this Eval stmt?
I am using Eval inside a datalist to populate a hyperlink within the datalist with a navigateURL value and I am using it as follows:
<asp:HyperLink ID="HyperLink_FullStory" runat="server" Text="Full Story" NavigateUrl='<%#Eval("LinkAddress")%>'></asp:HyperLink>
The issue I am facing is that the current page URL is getting appended to the 'LinkAddress'(the URL being fetched from the database) and thus,the final URL formed is not a valid one.Can someone suggest how do I remove the current page URL? Is there any way it can be done without writing code in the code behind page?

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.

I am pulling states from a database. When I get to "district of columbia" I would like to change the result to "washingtondc".

I have a datalist which acts like a table and displays certain values. I'm trying to display a boolean value as yes or no as opposed to true or false. This is what my current line looks like, is there any way to use an inline If statement to get this to work?
[Code]....
How can I make this show yes or no instead of true or false?
I am using C# and ASP.NET
i have the code to test:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =8", Con)
Now, I need something like this:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =" + LblInfoEditar.text, Con)
The problem:
The LblInfoEditar is outside the datalist so it works fine. (note: in this label I put a value like the 8)
But I have this label to test because I need to access a label inside datalist:
<asp:Label Visible="false" runat="server" ID="LblNumEntrevista" Text='<%# Container.DataItem("EntrevistadoCodigo") %>'></asp:Label>
The problem is: in this line I've to put something to access this LblNumEntrevista HOW?
I try:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =" +
ListaPendentes.LblInfoEditar.text, Con)
But of course I don't work because I can't do this...
I have some data which contains angle brackets in some of the fields.Even if properly escaped as <: or > (or even the hex codes), or contained in CDATA, in Visual Studio 2005 ASP.Net, the field data is being truncated at the first angle bracket. If I replace the data with curly braces, it displays fine.Is this a parser defect in the TreeView control? I can use Response.Write and see that the data provided by the XmlDataSource is fine. Example:
<ITReview>
<row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/>
</ITReview>
<ITReview>
<row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/>
</ITReview>
This truncates right after TT Description. If I change to curly braces or parentheses, it displays fine.
i have a FormView, it renders fields from a SQLServer database but also much static text specific to the database value I get. I dont know if this can be done in the code behind and put all this in a function . I put it in my formview
<ItemTemplate>
<% If Eval("Feature1") = "Yes" Then %>
<%# Eval("Username") %> A lot of text
<% elseIf Eval("Feature1") = "No" Then %>
<%# Eval("Username") %>
A lot of different text
<% End If %>
</ItemTemplate>
If I do the code above I get error message:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. Can this be done within the formview?

does the reason is square brackets ?

I have a repeater that has been given a datasource from my database containing pictures. The problem is that when i create and log a user into my site i send him to a folder that has no access from others than the ones with a roles called User. When he creates his profile, he uploads a picture which is saved in the same folder "User/picture/picturename" and in the database "picture/picturename".
Now i need to pull this picture to the Default page page where users are not logged in. If i add an Image Control to the frontpage with ImageUrl='<%#Eval ("PictureThumbURL") %>' it tries to pull out the picture from the folder User which is obvious that it can't since it lacks the User/ in front.
Is it possible to get this picture by manually adding User/ to the ImageUrl='<%#Eval ("PictureThumbURL") %>' and if so, how?
