I need to remove an item from the check box list ("cblServices") based on the query string value ("serveytype").
I pasted my code here.
[Code]....
When the query string ("serveytype") = 1, some of the items in the checkboxlist "cblServices" need to be removed before it's being Enabled = true.
Similarly, when "serveytype" = 2, some of the items need to be removed.,etc..
I need to charge my checkboxlist1 from database, eg load fruits and vegetables. When selecting fruits, new filter based on the previous selection in my checkboxlist2. for specific search.
View 1 RepliesThe following code works well as long as I pass a querystring value to the datalist.
Private Sub BindGrid()
Dim id As Integer = Integer.Parse(Context.Request.QueryString("id"))
Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Using con As New SqlConnection(strConnString)
Using cmd As New SqlCommand()
cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"
[Code] ......
However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.
Most websites have pointed me to this code to use:
<FooterTemplate>
<asp:Label ID="lblEmpty" Text="No Result" runat="server"
Visible='<%#boolean.parse(([b]list[/b].Items.Count=0).ToString())%>'>
</asp:Label>
</FooterTemplate>
The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.

I have a checkboxlist which is being dynamically populated. Code is below.
chklbCourses.DataSource = dt; // datatable returning
CourseName,CourseID and price

I am trying to get a drop down and a form view to work together. I've never used form views before. I also am using the entity framework to do everything. This is also my first time with it.

I'm looking for a way to get rid of the querystring of a page and redirect to itself but preserver the querystring data in some way. Exmaple: [URL] should redirect to [UL] Still, after the redirect, I want to be able to pick up the parameters that were originally passed. And I don't want to have [URL] in the browser's history.
What I tried so far:
* Response.Redirect(): does a proper redirect without creating browser history but I cannot preserver the parameters.
* Server.Transfer: preserves the parameters but the browser's URL remains unchanged.
* Create a client form on the fly and submit in "onload": works, querystring is gone, parameters are accessible through Request.Form, but creates a history entry in the browser.
The only thing I can currently think of is to store the parameters in the session, then redirect, then pick them up from there.
