Web Forms :: Processing Links In Dynamic Text?
Jan 4, 2010
I have a web page that loads in user-defined text from a database field into a label. This text may or may not contain HTML links (standard <a href> tags). I need a way to enumerate through the links and enable/disable certain links based on whether or not the person viewing the page is logged in or not (via a session variable).The html tags include a runat=server attribute and the text is standard formatted HTML. Since the text is being loaded into a label straight from the database, the links aren't loaded into the controls collection for the form - so, I'm not able to reference the links that way.

Let's say I passed a couple of querystring to populate my datalist on another page. Then I want to filter/refine that datalist further by clicking on links( which are dynamically created depending on the data on the datalist) and when clicked will pass another querystring to create a new refined datalist.
Example: I clicked on a link that redirects to [URL], a datalist will be produced on another page. Then there is are link on the same page that go to [URL], [URL], then another datalist will be produced. how to code these links, what I have in mind is link (4), link (10). The numbers represent how many records it will display if that link is clicked.

While c < 5
Dim Label1 As New Label()

Dim link As New HyperLink()
link.NavigateUrl = "simple.aspx"
link.BackColor = Drawing.Color.Aqua
Label1.Text = c.ToString()

Not sure if the derived page is actually relevant to the problem here, but ran into an interesting gotcha on some code I'm working through at the moment.
I have a custom masterpage class, which derives from System.Web.UI.MasterPage so that it can be extended with additional useful properties. The page that that uses this masterpage has a declaration at the top (note the Page Title being set).
<%@ Page Language="C#" MasterPageFile="~/MasterPages/Landing.master" AutoEventWireup="true" CodeFile="Index.aspx.cs" Inherits="Index" Title="Welcome to the site" %>
In addition, the master page has stylesheet references in the head which are pulled from a CDN that is defined in a config file.
<head id="Head1" runat="server">
<link rel="stylesheet" type="text/css" href="<%= CDN %>/css/main.css" />
</head>
Now the example above obviously doesn't work, because the runat attribute in the head container means that the codeblock in the the link is static text, and renders as is, in the resulting html.
If I remove the runat attribute from head, the CDN works, but now I notice that the Title is no longer being set. If I debug, and try to access Page.Title in the Immediate Window, I get an exception:
// Using the Title property of Page requires a header control on the page. (e.g. <head runat="server" />).
So, is there a way to get the Page Title from the declaration, put my own title placeholder in the head and set it from the master page code-behind, or, is there a better way to dynamically set the CDN domain for the stylesheets? The only way I think I can do that is to build the entire html link tag(s) and append it to the header control, but I thought there might be a more elegant solution, so I'm asking here first.

I have a stored procedure that has hyperlinks in it when I call that stored procedure into a gridview those hyperlinks are displayed which is fine. I want them removed when I export the gridview to excel but remember they are in my stored procedure.
Here's the query
SELECT '' AS reg, RegionAcronym, '<a href=nation.aspx?RegionAcronym=' + Regionacronym + '>' + 'PHI' + '</a>' as area,
SUM(totpenfodds) AS 'totpenfodds',
SUM(pendinfo) AS 'pendinfo', SUM(pendndds) AS 'pendndds',
SUM(pendfo300) AS 'pendfo300',

In my code below, I'm trying to re-write a string and convert and http text into actual web links.
It doesn't seem to be working and I think the problem may be that I'm rewriting the string and inserting another http string into the original string which then causes problems with the loop.

I have a project where I need to create menu buttons from a list in SQL Server. The problem I am having is that I need to add code to the text of those buttons. So there would be a birthday button and it should display the number of birthdays within the next two weeks or a button with the number of upcoming events.
Clarification:
There is no code yet, just some requirements. What I am doing is querying a table to get the list of buttons to display. Now each of these buttons may have dynamic text, for things like count of birthdays, events,etc... I am trying to see what the best way would be to handle this. Should I embed a snippet of code to go along with the menu item to execute when I iterate over the menu items? Maybe I should build a javascript file to go along with the code, which I add code to query a service for certain menu items?

We are in the process of building a huge site. We are contemplating on whether to do the processing of HTML at server side (ASP .Net) or at the client side. For example we have HTML files which acts like templates for the generation of tabs. Is it better for the server side to get hold of content section (div) of HTML load the appropriate values and send the updated HTML to the browser or is it better that a chunk of data is passed onto client and make Javascript do the work?

I'm working on a page which allows a user to do the following:
upload XML filevalidate XML filebulk loads data from XML file into MS SQL Server tablesruns a number of stored procedures to do certain checks on the imported data.
Now, I know how to do all of the above.
However, I would like to inform the user between the execution of the above mentioned actions what is happening.
I've looked at using the controls "updatepanels" and "updateprogress", but can't seem to get it to work.
If I put some static text like "Loading..." in the updateprogress control, I do see that whilst the code is running.
However, I don't want to show static text but want to change the text dynamically.
It appears that server-side controls are completely ignored inside the "updateprogress" control (why?).
Ideally I would like to do something like:
<form id="form1" runat="server">
<asp:ScriptManager ID="scriptMgr" runat="server" />
<div>
<asp:UpdateProgress runat="server" id="PageUpdateProgress">
<ProgressTemplate>
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
</ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdatePanel runat="server" id="Panel">
<ContentTemplate>
<asp:Button runat="server" id="UpdateButton" onclick="UpdateButton_Click" text="Update" />
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
In the code behind:
Protected Sub UpdateButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles UpdateButton.Click
Label1.Text = "Starting action 1."
System.Threading.Thread.Sleep(2000)
Label1.Text = "Starting action 2."
System.Threading.Thread.Sleep(2000)
Label1.Text = "Starting action 3."
System.Threading.Thread.Sleep(2000)
End Sub
Unfortunately I'm getting syntax errors on Label1.Text as it doesn't seem to recognize the control.
I know I'm a newbie and that I'm probably going around this completely the wrong way.
where I'm going wrong and how I can get this to work. I can't imagine I'm the only one who wants to achieve something like this in a webform.

I have a dynamic textbox appearing in a gridview on the row editing function. I have the following code to set the focus tot he textbox:
GridView1.EditIndex = e.NewEditIndex
BindData()
GridView1.Rows(e.NewEditIndex).FindControl("txtTargetAmount").Focus()
This works fine, but I would now also like to select the data in the textbox so the user does not have to select the text before typing, they can just type straight away. I have been trying to use:
txtTargetAmount1.SelectionStart = 0
txtTargetAmount1.SelectionLength = txtTargetAmount1.Text.Length
but this does not work.
