Server Control - Avoid Adding Multiple Javascript

Jan 26, 2010

I created an asp.net Server control that derives from a LinkButton, and renders a small javascript function to the page. I want to use this control many times on the page, but just want the javascript to be rendered once on the page. On the other hand, I rather not manually add it in a js file, because i don't want to have a chance of forgetting to add the js file in the future.

How To Avoid Adding Runat="server" Destroying Server Tags <%...%>

Jul 30, 2010

Adding runat="server" is not rendering my server tags <%...%>

I have a masterpage with a few <li> for menu and since I have to set class=selected for the current page, I am using a little server tag to find the url and assign the particular class.

I have total of 10 <li> and not all menu is available to all types of user, I need to toggle few of the <li> if the user is not admin, so I have runat="server" added to them so I can set their visible=false through c#

Here is how it is at a glance:

<li runat="server" id="liBlog" class='<%= Request.Url.AbsoluteUri.EndsWith("/Blog") ? "selected" : "" %>'><a href="/Blog">Group Blog</a></li>
<li runat="server" id="liPoll" class='<%= Request.Url.AbsoluteUri.EndsWith("/Poll") ? "selected" : "" %>'><a href="/Poll">Poll</a></li>
<li id="liInvite" class='<%= Request.Url.AbsoluteUri.EndsWith("/Invite") ? "selected" : "" %>'><a href="/Invite">Invite</a></li>
<li id="liFavourite" class='<%= Request.Url.AbsoluteUri.Contains("/Favourite") ? "selected" : "" %>'><a href="/Favourite">My Favourites</a></li>

The <li> without runat="server" works fine, when on correct page the source code shows class="selected" or class="" as appropriate, the other <li> used to work fine too, until I decided to add the runat="server".

Once I added that runat="server", the whole block of class="" is being sent out to the html page, its not processing the server tags at all! I right click on the html and look at the source, it's being rendered as:

<li id="ctl00_ctl00_ContentPlaceHolder1_liBlog" class="<%= Request.Url.AbsoluteUri.EndsWith("/Blog") ? "selected" : "" %>"><a href="/Blog">Group Blog</a></li>

It's pouring out my server tags into the source code!

Why is this behaviour seen? How can I avoid it?

Web User Control With Javascript Used Multiple Times On A Page - How To Make Javascript Functions Point At The Correct Controls

Apr 12, 2010

I think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.

SQL Server :: Adding Rows To Multiple Primary Keyed Tables?

Jul 27, 2010

I am accessing rows in an SQL database table based upon the contents of 2 Primary key columns. But, I cannot insert new rows in the table when the content in one of the new Primary key columns already exists in another row. I get an error message that says: "Violation of PRIMARY KEY constraint 'PK_ReferendumVoters'. Cannot insert duplicate key in object 'dbo.ReferendumVoters'. The statement has been terminated."

The reason why this error is occurring is because I first stored "Referendum 1" in one column along with "me" in the second column of a new row for a "ReferendumVoters" table. Then, I attempted to insert a new row with the same "Referendum 1" string in the first column along with a different name in the second column. But, it will not let me do this even though I created a new index that defines the two columns as unique. Is there any way that will enable me to do this?

Javascript - Adding Click Events To User Control?

Aug 28, 2010

I have a user control in an asp.net web application. The control outputs an html list that is customized based on the currently logged in user. The list items are generated from a database look up and the user control is formatted to appear as a drop down list in the page.

The control itself is simple and looks like this:

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="item-lector.ascx.vb" Inherits="includes_usercontrols_item_selector" %>
<!--Item Selector-->
<div id="item-selector">
<%=Me.Output%>
</div>

The code behind file dynamically fills the control's "output" property so the final markup appears as follows:

<div id="item-selector">
<h1>Item 1 - Item 1</h1>
<a href="#" class="changeItem itemArrow">Change item</a>
<ul id="changeItemMenu" class="dropDownMenu">
<li><a href="#">Item 1</a></li>
<li><a href="#">Item 2</a></li>
<li><a href="#">Item 3</a></li>
<li><a href="#">Item 4</a></li>
<li><a href="#">Item 5</a></li>
<li><a href="#">Item 6</a></li>
<li><a href="#">Item 7</a></li>
<li><a href="#">Item 8</a></li>
<li><a href="#">Item 9</a></li>
<li><a href="#">Item 10</a></li>
</ul>
</div>

The ID and class properties are all necessary for formatting and other scripting. The control is meant to be used as a selector and the rest of the page should react to which item the user selects.

What I am trying to do is add click events to the list items. When the user clicks on one of the items in the list, I want to capture which item the user selects in the list (does this require a postback?) and do something with it in the code behind (< this is key).

I am more of a middle tier and db tier developer and UI development is not my strength so please consider me a newbie in that regard. I am not sure how to proceed or what to inject into the output string to enable this.

Mar 16, 2011

I wanted to stop multiple login of the same user. So, I created a table which keeps track of users who have logged in. When they log in, the data will be entered in the table. When they click on logout, data and session will be removed. The problem is, when they close the browser window without logging out, they won't be able to login ever again.

Web Forms :: Regex - Avoid Replacing Multiple Matches With The Same Value

Feb 12, 2010

I have a dummy html file:

.....<body>
<p><a href="http://www.google.com">link 1</a></p>
<p><a href="http://www.google.com">link 2</a></p>
<p><a href="http://www.google.com">link 3</a></p>
<p> </p>
</body>

I need to add a autoincrement int after the http://www.google.com, though unique for each occurance so the result will be:

<body>
<p><a href="http://www.google.com" 1>link 1</a></p>
<p><a href="http://www.google.com" 2>link 2</a></p>
<p><a href="http://www.google.com" 3>link 3</a></p>
<p> </p>
</body>

Obviously with .replace I get [URL] 3 2 1 > 1 and so on... I am thinking of contructing a two dimensional Array where myArray[0][0] will be the first match like myArray[URL][0] the second element the second match. myArray[URL][1] and so on. So then I would iterate through the second dimension of the array. Will this work? I am thinking that it won't...

Queue Access To The Database To Avoid Multiple Cache Items?

Jun 7, 2010

I have a music related ASP.NET web site which caches a lot of static information from the database on the first request.Sometimes, the application is reset and cache is cleared while the application is on heavy load and then all http requests go to the database to retrieve that static data and cache it for other requests.

How can I ensure that only one request go to the database and cache the results, so that other request simply read that info from cache and not needlessly retrieve the same info over and over again.Can I use thread locking? For example, can I do something like lock(this) { db access here }?
