C# - HtmlInputHidden Control - Stop Name From Changing?
Aug 30, 2010I have an asp.net page and I'm trying to add a couple of hidden HTML input controls. I will be submitting this form to another site (PP) so I need the names of the controls to NOT change when rendered. Is there a way to make ASP.NET honor the name property that I set in the code-behind?
As an alternate, I don't need to dynamically create these controls, I can also just assign the value to an existing HTML field but I don't know how to do that with ASP.NET/C#

Changing CSS Class Based On Querystring
Jun 12, 2010I have a repeater control that generates a dynamic menu in an unordered list format. I have given each <li> item an id that includes a value from my database to make them unique:
<li id="category<%adding in my dynamic value from database here%>"><a href="#">Some Link</a></li>
One of the values that gets added to my list ids will match my querystring, making it the current page. So therefore I would like to highlight this to the user by changing the css class of the relevant li element. In my code behind I have created a string variable that takes the querystring value and modifies it to match the id. So for example my variable is "category7" - and I also have an li item on my page with an id of "category" How would I go about matching these two things in my VB and adding a class to the li element where the id = my variable.

View 2 RepliesHow To Declare A C# Web User Control But Stop It From Initializing
Apr 2, 2010I have a C#/ASP.NET .aspx page that declares two controls that each represents the content of one tab. I want a query string argument (e.g., ?tab=1) to determine which of the two controls is activated. My problem is, they both go through the initialization events and populate their child controls, wasting CPU resources and slowing the response time. Is it possible to deactivate them somehow so they don't go through any initialization?
My .aspx page looks like this:
<% if (TabId == 0)
{ %>
<my:usercontroltabone id="ctrl1" runat="server" />
<% }
else if (TabId == 1)
{ %>
<my:usercontroltabtwo id="ctrl2" runat="server" />
<% } %>
I assumed the that <%'s would have meant the control wouldn't actually be declared and so wouldn't initialize, but that isn't so...

Dec 7, 2010Problem Statement: I have a details web page which has a unique sesssion ID generated per user.

Changing User Name In A Table?
Mar 8, 2010I am using profiles to store extra information about users. The thing that I want is that I am changing user name. But on the other side I have photo album gallery where I have stored the User name (Creator of album). These two tables (aspnet_Profiles and PhotoAlbum) are in different databases.
I have tried the following code while changing the user name
Private con As New SqlConnection(ConfigurationManager.ConnectionStrings("Photo").ConnectionString)
Dim updateSql As String = "UPDATE PhotoAlbum SET UserName = @UserName WHERE UserName = " & userName.Text
con.Open()
Dim myCommand As New SqlCommand(updateSql, con)
myCommand.Parameters.AddWithValue("@UserName", newUsername)
myCommand.ExecuteNonQuery()
con.Close()
Here newUserName is the new user name field and UserName is the previous name stored in PhotoAlbum table.
But it does not seems to work.On debugging it reports Invalid Column Name "userName"
