View 1 RepliesI have a script manager and calendar extender on my aspx page. When I call a javascript function from my code behind page, the calendar extender doesn't work
ScriptManager.RegisterStartupScript(Page, this.GetType(), "javascriptfunction", "<script language=javascript>function();</script>", true);

I have an AJAX auto complete extender that calls a web service to generate a string[] for a textbox. Works great, The issue I am having is that I set the OnClientItemSelected property of the auto complete extender to call a JavaScript function that will intern call another web service to get the remaining data I need based on the item that was selected. (I need this because the auto complete web service only allows for key/value pairs and I need to return 10 columns of data) I cannot get the JS function to call the web service. I keep getting "(Namespace) is undefined" as a JS error. I tried to impliment Microsoft's example located at: [URL] but even if I copy there code line for line in a new project, I still encounter the same error.
Samples.AspNet.WebService.Add(a, b,SucceededCallback); //'Samples' is undefined - runtime If I remove the namespace so that it reads: Add(a, b,SucceededCallback); //Endless loop until you get stack overflow error
Has anyone got MS C# example to work? I saw a lot of people had this line missing in the web service, but I already had it. [System.Web.Script.Services.ScriptService]

Is is possible to call a Javascript function whether it's embedded in the HTML markup file or a .js file from a VB.Net procedure/function?
View 3 RepliesI am trying to call some javascript functions which I ahve written in some file. Eg.
function OpenPopup() {
alert("OpenPopUp");
return false;
}

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 wanted to show or hide duplicate records according to query. So, I need to know how to call the javscript function from C# codebehind.
<a onclick="Grid1.insertRecord(); return false;" id="a2" href="javascript:">Save</a>
When I click save i need to show a popup which i Have written in javascript.
if (!exist)//exists is the query
{
System.Web.UI.Control my = FindControl("a2");
a2.Attributes.Add("onclick", "retrun HideDuplicate()");
This line returns an error saying "a2 doesnot exist in current context."
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.

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 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
View 1 RepliesI'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.

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 am trying to call a Page Method using AJAX.
See the code
<asp:Button ID="btn_upload" runat="server" CssClass="btnEffects" Text="Upload"
onclick="btn_upload_Click" OnClientClick="return Validate();" />
Validate method is supposed to return true/false. The code for Validate method is
<script language="javascript">
function Validate()
{
var filename = $get('<%= txt_filename.ClientID %>').value;
PageMethods.IsValidFile(filename,OnSuccess, OnFailure);
// IsValidFile is a Page Method of bool return type
}
function OnSuccess(result)
{
if ( !result)
{
alert('File '+ $get('<%= txt_filename.ClientID %>').value + ' does not exist');
return false;
}
else
{
return true;
}
}
function OnFailure(error)
{
}
</script>
My problem is that even after showing the alert 'File somefilename does not exist'. The whole page refreshes (i.e, postback happens)
