Calling Javascript From Codebehind?
Sep 16, 2010I have read many different resources but am still not sure if this is possible without using AJAX.
I have a javascript function that loads a div into a modal and says "Loading Please Wait" I have named this funciton loadingModal()
function loadingModal(url)
{
loadModal(...)
}
What I need to do is only trigger this after I have verified that the password and username are correct on the server side so:
btnSubmit_OnClick(object sender EventArgs e)
{
string usr;
string password;
if (verify(usr, password))
{
///// TRIGGER JAVASCRIPT HERE
LOAD TONS OF SESSION VARIABLES
.
.
.
}
else
Show Error and Definitely Don't ever mention still loading
}
I know I could just attach an onclientclick call to the javascript however it would load the loading modal even if it was an invalid username and password
Can I trigger javascript mid execution from the server side?

JavaScript - Create Css Class On The Fly In Codebehind
Aug 4, 2010I have a search page that is used in multiple places with multiple 'themes' throughout my site. I have a few divs that can have their background color changed based on a radio button selection (whether they are enabled or not). I can do this just fine by changing the css class of the div on the fly with javascript.
However, these themes could potentially change, and the background color is grabbed from a database when the page is created. Right now I do this in the C# codebehind:
string bgStyle = "background-color:" +theme.searchTextHeaderColor +";";
OwnerSearchHeader.Attributes.Add("style", bgStyle);
In the Javascript I need to change this color to make it look disabled, and when the user clicks back to this div I need to re-enable it by changing it back to its original color. But since I only knew this color in the code-behind, I don't know what it was in the Javascript.
So my thought was to create a css class in the resulting HTML page when the page is loaded with the background color I need. Then I could simply switch from the divEnabled and divDisabled class in the javascript. But I'm not exactly sure how to do that.

View 5 RepliesJavascript - Determine Generated ID's From Codebehind?
Mar 14, 2010In ASP.NET, when you give a tag an ID it generates a unique HTML id for the element based on the control hierachy, ie.

C# - Executing A Javascript Function From Codebehind?
Nov 3, 2010OK, this feels like a question that should be easy to answer, but as with so much mixing of asp.net and jQuery, it's a bit of a nightmare.
What I want to do is be fading a div in and out at various times during the client's viewing of my asp.net page; I fade it out using jQuery's fadeTo() before triggering an UpdatePanel update (to indicate that the data there is not fresh) and I want to fade it in again once the UpdatePanel has been updated. I've gotten as far as updating the UpdatePanel in the codebehind, and this results in the div's content changing... but how do I fade the div back in again?
The way I see it, there are 2 ways; register an event handler on page load to detect when the div's content has been changed and fade it back in, or call a function from the asp.net codebehind when I've updated the div to fade it back in.
In the first case, there doesn't seem to be any event triggered by the div's content changing, so I can't seem to do that. If anyone knows how I could get a client event to trigger when I update the div, that would be a nice solution.
In the second case, I thought that this was what ClientScriptManager was for, but it doesn't quite do what I want. I want to be able to register a particular Javascript function with ClientScriptManager and then tell ClientScriptManager to execute it in the client, from my codebehind. You can't seem to do that. ClientScriptManager.RegisterClientScriptBlock() simply inserts some <script> into the HTML output, rather than calling a function. Presumably this would work if I kept registering things like:
<script>fadeBackIn();</script>
because the Javascript would be immediately evaluated and run, but this feels messy, and that feeling is intensified by the fact that I'd have to keep randomly generating a new unique value for the key argument of ClientScriptManager.RegisterClientScriptBlock(), because it's specifically designed to stop this kind of repeated code. However, I'm struggling to see an alternative.
I'd really like something along the lines of:
ClientScriptManager.RegisterClientScriptFunction("fadeBackIn", "function fadeBackIn(){ ... }");
ClientScriptManager.ExecuteClientScriptFunction("fadeBackIn");

View 2 RepliesC# - Setting Hidden Input Value In JavaScript, Then Accessing It In Codebehind
Apr 21, 2010I have been trying to set the value of a hidden input by using Javascript and then access the value from within my C# codebehind. When I run the code that is copied below, the value that is assigned to assignedIDs is "", which I assume is the default value for a hidden input. If I manually set the value in the html tag, then assignedIDs is set to that value.
This behavior suggests to me that the value of the input is being reset (re-rendered?) between the onClientClick and onClick events firing.
