How would one go about creating a facebook-style "Like" button in C# ASP.NET without doing a postback? Are there any code examples or tutorials that you know of? I assume that would have to use asynchronous javascript. (this is a tough one to search for due to the Facebook keyword!)
This would have to work with .NET 2.o framework, SQL Server 2005 and VS 2005.
I need some high-level advice on how to deal with this issue. I want to have dynamically created buttons, each with a different CommandArgument, that call an OnCommand event when clicked. Given that these are dynamic buttons, I have to re-create them in Page_Load after the postback. However, when I re-create the buttons, the orginal command arguments are lost, and the arguments generated after the postback are only valid.As you'd expect, if I don't recreate the buttons, the event handler is never called because the buttons don't exist.My question is, how can I retrieve those original commandarguments, without the use of sessions.
View 6 RepliesIam Creating a Hyperlink control in code behind user this way
string literalControl = "<asp:HyperLink ID="HyperLink1" onclick="fnClearField('asdf')" ForeColor="Red" Font-Underline=true CssClass="Row_Over_Ar_Ex" runat="server" >Clear</asp:HyperLink>";
cell.add( new literalcontrol(literalControl ))
but the control not showing all the style attributs, is this way the style attributes will not show?
do i have to create the server control using new hyperlink and then add all the attributes?
Let's say i have the following ASP.NET/CSS code:
<div style="color:Red;">
some text...<asp:Button runat="server" ID = "Button1" Text = "ABC" />
</div>
The "some text" part would be red but the text of the button is not red. Why? If I place a label in place of the button, the label's text would be red.
dynamically created style of a panel. On postback the style of the panel is getting reset to its design time style. I am assigning the style of this panel using javascript. on dropdowlist's index change, its getting reset.
View 3 RepliesFirst time using an Accordion Control and I'm having some trouble with the CSS, as per the subject description. I have only created the headers so far and assigned some basic CSS to them. Right now that CSS is only there to limit the width (and therefore clickable area) of the header to the width of the image that the header is represented by. This works fine until I click on one of the headers and then its width property is lost. Same for the other headers, they are fine for the first click and then after that they lose their style. There is no postback caused by selecting a header so this is not the reason that the CSS is being lost.

I have a script that runs during the Page_Load() event which checks a database table to make sure that the user is still owns the lock on the page. If they no longer own the lock, I disable all the controls on the page and display an
error message.My thinking was that by disabling all controls during Page_Load() I could prevent any PostBack events from occuring. For example, I have a button on the page called "Save and Quit"

A have a web page that does an AJAX callback. When the CallBack event is handled, my ASP.NET code generates some JavaScript that is then returned to the browser. The idea is that this JavaScript will then immediately be executed. The reality is that it isn't....

I have some CSS that uses lists to create 3D buttons styles similar to the link below:
http://articles.techrepublic.com.com/5100-10878_11-5323375.html
My problem is I have buttons which are server controls and thus render html buttons.
The question is how would I rewrite my button code to use lists and hyperlinks so I can apply the CSS which has been already written?
All I am doing in my button code is within the onclick event setting a string value and calling a method by passing it that string value.
I'm after is some onclick event equivalent i can hook my code into for hyperlink controls.

My <style> for thumbnails currently looks like this:
<style type="text/css">
img.TN {
width: 100%;
margin-bottom: 5.294%;
cursor: pointer; }
</style>
This is annoying, because I have to apply this style to every single thumbnail image individually, when there could be any number of them on the screen at any given time. All of the thumbnails are inside a single <div> that groups them together, and I'd like to apply a single style to the <div> that will push the attributes I need down to all of the the <img> elements nested inside, regardless how many thumbnails there are.

My code behind:

The event fires when the btnTransport button is clicked but it never recognises if a check box is or isn't selected and therefore never builds the mpString (line 17).
Is there a built in function/property for this or is it best to use the findcontrol method?
There is a Textbox and a button when user clicks on the button after entering the data in the textbox I want that new page is created .

Unfortunately nothing actually happens...am I missing something?
Edit -- Fixed
I was missing something! I had CommandName equal to my method name instead of OnCommand. I took out CommandName, kept the argument bit and replaced CommandName with OnCommand. Everything works now, but what would I ever need CommandName for?
I'm creating a web server control that has an image button on it.The html for the control is done in the RenderControls of the code, the control devrives from WebControl, IScriptControl, INamingContainer.The button is coded as follow in the RenderControls:
System.Web.UI.WebControls.ImageButton img = new System.Web.UI.WebControls.ImageButton();
img.ImageUrl = "Url of the image";
img.Click += new ImageClickEventHandler(img_Click);
img.ID = this.ClientID + "_img";
img.CausesValidation = false;
imgLock.RenderControl(output);
The button apreas in the browser but when i click on it, the page postsback but the event handler for the button doesn't get fired, from what i can figure out, since the control goes throught RenderControls eachtime the page is posted back, the button gets redrawn and the event handling disapears.
