C# - Calling Javascript From A Code Behind Vs. Calling A Code Behind From Javascript
Mar 8, 2010
I have a web application that will need to access code behind methods as well as javascript methods. For this particular implementation it doesn't really matter which order they are called in from a program flow perspective.
I'm looking for insight into when it would be appropriate to use a code behind to call javascript and when it would be appropriate to call javascript from a code behind. Are there any ramifications of doing it one way or the other that I should be aware of before moving forward with an implementation?
Is there a best practice way to do it or is it very specific to the actual implementation?

I have a JavaScript-based timeline which needs to use data from an SQL server. The queries and the JSON conversions have been worked out in the form of C#.NET functions within a code file related to an .aspx page. So for a complete newbie to ASP.NET, how do you set up a function call like this from JavaScript?I would love it if someone had some simple example code I could learn/get some pointers from.Edit: I am using .NET 3.5

So I have this idea of creating a asp.net user control, to handle all forms of modal popups (whether it be error handling, forms, dialogs, etc).
I already created this before, placing the user control in the top master page, exposing it to all content pages, so I could do something like:
Master.Popup.ShowException(Exception);
And the usercontrol itself would have the necessary markup to look like a modal dialog, and in the show method just do a .Visible = true.
This is all fine, but I've started thinking of implementing a bit of style with jquery. I'd like for the usercontrol to have some sort of jquery animation on show. But I don't know how to go about achieving this, as I don't know how I would call that jquery function from the codebehind instead of the popup.visible = true.

I have a java script function which presents a countdown timer.when the timer reaches zero, I want to somehow activate a function on the server side in the code-behind.I understand it is impossible to directly call a server-side function, but is there a simple way to still fire it?I want to fire the (event-handler) code behind function: protected void ButtonFinish_Click(object sender, EventArgs e).
var _countDowncontainer = 0;
var _currentSeconds = 0;
function ActivateCountDown(strContainerID, initialValue) { _countDowncontainer = document.getElementById(strContainerID);

I am using Ajax's EnablePageMethods way to call server side code using javascript. The problem is that in IE8 the page automatically refreshes after the ajax call has been completed i.e. the server side function has been executed successfully. I want the same to happen with Chrome and Firefox but it doesnt refresh the page once the server side function has been executed.
I am using this way to call server side code from Javascript -- [URL]
this is the javascript function:
[code]...
this is where i am calling the javascript event:
<a href='myPageName.aspx' onclick='javascript:editNode(1);return false;'>Delete</a>

I 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?

I'm trying to implement the cascading dropdown from the toolkit. I need to get the count in a sub category dropdown, if it's zero then I turn off the visibility of the sub category.If I use the javascript OnChange event then my script fires before the web method, so I need to know how to fire my script AFTER the web method has fired please.
My demo page: http://bit.ly/92RYvq
Below is my code and the order I need it to fire.
[WebMethod]
public CascadingDropDownNameValue[] GetSubCats1(string knownCategoryValues, string category)

StringDictionary kv = CascadingDropDown.ParseKnownCategoryValuesString(knownCategoryValues); [Code]....

how to call a partial view from within a Javascript function? I've looked around the web, but all the examples that I have been able to find are examples using Ajax.ActionLink or Ajax.BeginForm.
When a user clicks on an item, I want to be able to hide/display some Divs and possible do other operations before calling the partial view. ActionLink doesn't appear to provide that ability. Depending upon the item the user clicked, I may be assigning the results of the PartialView to the same Div, or to a different Div.
What I'm looking to achieve, is to have an onclick handler associated with the item which performs whatever other operations might need to be done, then assign the result of the call of the PartialView to the appropiate Div. In some instances, the function might even be making two separate calls to PartialViews, to update the content of two separate Divs.

I often want to call a function in the code behind using the "<%# ... %>" syntax. Sometimes is works and sometimes it doesn't. It is also a difficult syntax to search for. Can someone point me at an explanation of the working (or not) of this syntax?
I just tried this:
<asp:TextBox
ID="TextBox1"
runat="server"
Text="<%# getBCSConnectionString() %>"
></asp:TextBox>
For example. The function is in the code behind (it returns a string). The TextBox is empty and no break point is hit in the function; it does not appear to be called.

I'm new to Borland C++ Builder and the application that I'm working on has to be launched from a ASP.net application on click of a button. That ASP.net application is able to launch other EXEs (made in C#) but when my application is launched it crashes immediately with a msg "an error has is encountered, tell microsoft about this problem" with button "Don't Send" "Send error report" and "debug". The ASP.net program is able to call "notepad.exe" which is probably not written on .net.
So, how do I call an application from ASP.net/c# which written in Borland C++ Builder and is launching successfully when I double click the application.

Now I would like to move this same WebForm functionality into a AJAX Control Kit TabControlPanel

Here is what I have tried, but it won't compile. I get the following error. Where do I put the script and how do I reference controls in the AJAX TabControlContainer?

I have a button on which I wish to validate a specific ValidationGroup in ASP.NET. This button is not a server control, but a standard a tag with an onclick event on.
I have multiple validation groups on this page, so by calling Page_ClientValidate() is not enough, as the other validators will kick in as well.
