I want to print series in one cell of gridview sccording to condtiotion. I have used condition from ternary operator like
<%# Eval("Sequence").ToString()=="R" ? "Sequence1" : "Sequence2" %>
but i want to print series instead of string Sequence1 and Sequence2 by loop.
Can somebody show me a better approach of looping through a Try -Catch statement. I have something like this:
Try
dbConn.Open()
Catch ex As Exception
errmsg = ex.Message
End Try
I need to try to connect 5 times before logging an error. My first thought was to nest Try - Catch 5 levels but I didn't like that idea. I'm sure there is better solution to it.
Basically what i am trying to do is display a list of categories. And if the admin is logged in
i want to show some buttons next to each category. For example a button to delete it. The problem is that i dont know how to pass a parameter to the function that does the action.Like i specify that on button click the function 'DeleteCat' must be called but if i cant pass the ID of the category to be deleted this wont work.I know this can be done with commands and a repeater, but its not an option, i cant use a repeater.So apparanly this is what i am aiming for:

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 have menu item on my master page that has block around the text when the page is first run. I wrote in the css on the link and visited property to change the color to match the image color that it is on. When a menu item is clicked the color changes to the right color. How do I get it to the right color on when the page first opens or is there a way to get rid of the block or make it transperant?
View 1 RepliesI have 2 separate code-block asp.Net expressions in an aspx markup, with an html content between (span element in the example below). In the first code-block, there is "i" as an increment variable for the for loop.Then the code-block is cut with an html content.And another code-block expression is opened but as I see I can reach the "i" variable which was declared in the previous code-block.
So, how asp.net handles -compiles- the pieces of code-block experrions declared in the mark up? Does it check the semi-colons and generates some anonymous methods which will end up with many calls to Response.Write in the last place?

Im stuck with declaring a string which is in a loop within another loop.
Dim CompanyDetails As String = ""
Dim CompanyRow As DataRow
For Each CompanyRow In newdt.Rows
CompanyDetails += CompanyRow(1) & " " & CompanyRow(0) & "<br/>"...
How can I get this to see the GetInfo as declared..... since its in a loop within a loop?

View 3 Repliesi have users who can logon to my site. I don't use the asp.net provider (i have my own user storage) but do use forms authentication. No i want to block users from log on twice to my app. Now what is the simplest thing to accomplish this? I thought about an extra field in the database in the user record but is there something simpler? is there a sort of 'session' for the entire application where i can remember who is logged on (and which is not flushed at a random time)? maybe in the cache (but the cache is sometimes flushed) i've seen an example where a file with the username was written to disk (and removed when logged out)
EDIT:
Good question was: what do you mean with logon twice. I mean when a user logs on on another computer or when another person logs on with the same credentials

View 1 RepliesI have a simple wcf service like this, with a test method which simply sleeps for 20 seconds and returns a value. I wrote a test page which uses jquery to call it 10 times in a row, and it appears to execute concurrently, with the client waiting 20 seconds and then getting results back from all of the services at about the same time.
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall,ConcurrencyMode=ConcurrencyMode.Multiple,UseSynchronizationContext=false)]
public class AjaxTestWCFService : IAjaxTestWCFService
However if I set
aspNetCompatibilityEnabled="true"
in web.config then no matter what I do, with concurrencymode, usesynchronizationcontext or instance context mode, or even serviceThrottling config, it appears to execute each web service call sequentially, with it taking 2 minutes for all 10 requests to return!!
Now I realize that this may be because of session, but at least in ASMX services I was able to set enablesession to false. And in fact my web service method is not using session at all. So you may wonder, why use aspNetCompatibilityEnabled at all. Because I want to use ASP.net impersonation and forms authentication.
I even set
[ServiceContract(SessionMode=SessionMode.NotAllowed)]
So my question is, is this by design and how can I enable concurrent web service requests with ASP.net compatibility enabled?

View 6 RepliesWhat 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.
I have tried a few things without any luck.
<a href="http://MyWebsite/ActiveUsers?ID=InsertEvalHere"><%# Eval("Name")%></a>
The following code below is what I have tried to do:
<a href="<% "http://MyWebsite/ActiveUsers?ID=" + DataBinder.Eval(Container.DataItem("ID"))%>"><%# Eval("Name")%></a>
<a href="<% "http://MyWebsite/ActiveUsers?ID=" + Eval("ID")%>"><%# Eval("Name")%></a>
<a href="http://MyWebsite/ActiveUsers?ID=<% DataBinder.Eval(Container.DataItem("ID"))%>"><%# Eval("Name")%></a>
<a href="http://MyWebsite/ActiveUsers?ID=<%# Eval("ID")%>"><%# Eval("Name")%></a>
None of the above seemed to be right, as I keep getting this error - The tag is not well formed.
How should I handle this?
